My husband and I recently returned form a trip to Israel and every toilet we saw was dual-flush. Europe has had a lot of them too in public settings starting in the late '90s. I'm on the Board and my husband is going to submit an agenda item for our monthly meeting presenting the benefits to our high rise of giving an incentive for owners to purchase/install dual-flush toilets.

Our HOA pays for water and the sewer rate is about 130% of our water bill each month. We have 211 residential units = about 240 toilets. At 14 y.o., many owners have already replaced their dated toilets; he & I now have two dual-flush models, but the majority of owners do not.

The old ones have flappers that leak that residents often don't fix. I started a program a few years back where our engineers would replace flapper at no cost to residents and we saved $1800 in six months. Unfortunately, the engineering contractor stopped allowing our engineers into the units except for emergencies.

Dual flush toilets save water and also are less likely to clog (very important in high rises!). They range in price from your basic Home Depot model for $100 to $1,000 and even more for toilets with all the bells & whistles and side-flusing handles. (Most models have the flush buttons on the top of the tank.)

From what I've learned, the dual flush will use on average 1.28 gal. per flush (gpf) vs. 1.6 gpf. But I don't know how to calculate how many gallons per year that saves per toilet. Apparently there's an average flush per resident, but I can't find those data. I've seen info about the "average family" will save ..., but I'd say we're under 2 people per unit. Anyone know how to get an accurate number??

I'm thinking that we could offer $100 incentive per toilet. Does that make sense? From what I can gather, the savings should be close to $80-$100 per toilet per year including sewer. But I'm not at all confident.

You can estimate the savings. Figure that the dual-flush saves .30 gallons per flush over the 1.6 gallon-models. Then count the number of flushes you make in a day and multiply the number of flushes times .30 gallons. Then multiply that times the number of people who live in your building.

If you assume an average of ten flushes per day times 211 units times 2.5 occupants per unit times the .30 gallon savings, you would come up with a figure of 1582.5 gallons per day. Monthly water savings would be 47,475 gallons per month. Your mileage may vary.

Check with some of the local water agencies, as the rebates they offer essentially paid for the toilets, including the installation.

If it were me, and I had a perfectly good working toilet, I wouldn't spend $400 for a new toilet and $300 to install even with $100 incentive.

FREE dual flush system:

If it's yellow, let it mellow.
If it's brown, flush it down.

'Pee' left in a bowl until the next use of bowl will neither smell nor stain.
With the lid down it can not even been seen.

We bought a dual flush system that you add to the existing tank for about $25 in Costco which was very easy to install. The knob has a place to push on top for liquid waste and the bottom knob is for solid waste. We have had it for 3 years with absolutely no problems. Even if we did have a problem, Costco accepts all returns We had a significant savings in our water bill. Since we are free standing homes I did put the information in our newsletter. Only one person I know of bought one and has complained about it --sometimes you have to hold the button for 2 or 3 seconds ---but he complains about a lot.

This small addition definitely saved us money on the water bill

Thank you everyone!

First, I mistyped the number of residential-unit toilets here. It's about 440 (not 240).

PitA, we Cali folk are very familiar with the old slogan from, when?, the '70s? We do remind residents about water conservation about 3X a year in our newsletter & include tips about washers, dishwashers, showers, teeth brushing, regular water use, toilets.

Cecelia, thanks for the tip! I did read about those kits and they seem pretty effective. My husband'll include them in his agenda item.

Steve, If you were on the board of HOA with an annual water bill budget of $62,000 and an annual sewer budget of $80,000 I'd hope you'd be trying to think of conservation strategies too. And that you'd encourage others. Even if only 25 owners replace their old-style flush toilets with dual flush ones, we'll be in a better financial place. There is, by the way, a certain element of owners here--for better or for worse-- who like to possess the "latest." The sleekEZ-to-clean single-piece comfort height toilet with self lowering lid & rim & dual flush tech costs about $550. My understanding is that installation is about $125 (my husband did ours).

Richard. I'll check on rebates for both the toilet and the installation. Thank you! It'll be useful info to have. And maybe it's not too late to get it for the one we installed in April!

Larry, I really appreciate your math help. I haven't done the calculations yet, but I do think, since 25 units (of 211) are only occupied part year and the rest have slightly less than two occupants per condo, I have a start. I did find the av. flush per day at somewhere between 6 & 8 per person, so that'll help too. I know we can't be exact, but our onsite engineers' ll be able to do the research.

Steve, I'm not getting your attitude. Why start a trial program when, if the Board approves the incentive, we can invite all owners? it costs the HOA nothing. We'd have the program on our web site, send an email blast and put it in our newsletter.

Even in high rises, a few residents do their own plumbing so long as it doesn't require ARC approval. Seating a toilet does not. My husband & I have an HO6 policy that includes covering water damage to other units and loss of use, or damage to the common area caused by us. But, again, Steve, why the snarkiness?

speaking as a retired plumber:

'dual flush' = 1.28 versus 1.56 (in actual practice)

a 'hi-end' will save $

a 'lo-end' which must be flushed twice will cost $

more savings will be obtained by actually servicing the toilets once a year for flapper issues and proper water level settings

try to get the members together for an annual 'bowl check' by a reputable 'handy man'

Apparently, PitA, the tech for dual flush now means that no matter what one costs, the flush force is the same. I did fine that on a google search. The price difference is for all kinds of extras now available on the market. You know, not only heated seats an self cleaning bowls, but the ones that you approach and the lid automatically raises?

A team of techs has been in our units cleaning out the clothes dryer ducts. Our lead security officer accompanies them and has put the blue tablets in the units' toilet tanks to check for leaky flappers. If he sees one, a request is sent to the unit owner to repair it. But we can't force them to.

I tell you, PitA, when our engineers were permitted to go into units to replace worn flappers at no cost--those were the glory days!

I have two toilets and I replaced one with a dual flush. It saved me as much as $15 a wk. if/when I need to replace the other a dual flush will be the choice.

the difference in the flushes is about 1 quart

at 4 quarts per gallon it would take 4 THOUSAND flushes to save 1 'unit' of water and sewer charges (assuming you are billed per 1000 gal)

your 'perceived' savings were probably due to having a new toilet installed

ps. 4000 / 30 = 133 flushes per day

assuming 3 people and 10 flushes each that would be 30 flushes 'over' 133 so your actual savings would be ?????????

pps. I fully realize the actual facts are unpleasant to hear

Kerry;

The 'dye test' takes 15-20 minutes.

Do the math as to whether they 'waited' to actually find SMALL (but continuous) leaks.

Trust me, MAINTENANCE is what saves $$$, not 'newfangled' gimmicks.

IMO: as these (newer) dual flush tanks begin to fail 'en masse' you will REALLY start to see waste as VERY VERY FEW will able to DIY repair ~ most are NOT repairable via a simple flapper replacement as they have PROPRIETARY mechanisms ~ they do, however, work well when 'brand spanky new'

Again, I appreciate your reply, PitA. I assume one of them was for Sally. $15 a week savings doesn't sound accurate.

I still haven't done the math partly because it's now become too late for my husband to submit if for our July 1 board meeting. Too busy with life!

I do think thank with soooooo many dual flushes in Israel and Europe and apparently required in parts of Australia, there must be some savings involved. We first saw them in Europe in the late '90s, so I imagine some have reached maintenance-issue age, but they keep installing 'em. And, look, 90% of our residents don't even know what a toilet flapper is let alone how to change them out.

Maintenance, of course, is best! But we can't force owners to maintain their toilets.

Actually, because our dryer vent starts in a laundry closet and the duct work runs 30-40 feet to terminate at our balcony ceilings, the techs do spend about 20 minutes in every condo. Long enough for the blue tablets to show leaks. They open ceiling hatches, clean the lint from the booster fan mechanism and check the duct from the dryer to the ceiling. In the balconies, they take off the ceiling duct cover and vacuum inside the duct. Just more of the issues in high rises! But I wouldn't live any other way!

European toilets are much more expensive AND better made.

European business law is COMPLETELY foreign to us.

If something fails to operate as expected / implied the SELLER is DIRECTLY responsible.
(the seller may, or may not, have recourse against the manufacturer)
The buyer gets IMMEDIATE repair or replacement + all damages = more expensive

ps. a European plumbing fixture is VERY difficult to retrofit into a USA home

I am not referring to Euro fixtures designed for export to USA but Euro fixtures designed for Europe plumbing systems

pps. the above 'tears the heart from my chest'

Sorry but can I mention that some people may not like the HOA being all up in their bathroom habits... LOL! Unless it is a retirment home, not many want to hear "two flushes or one?"...

It is a good suggestion to homeowners to incorporate but unless you all decide to fund the whole project together, then education is the way to go. I do not think the HOA should be responsible for such items. However, Real Estate agents selling the homes may like the feature to promote.

Melissa, I think I don't understand your post. I wonder if you know what a dual flash toilet is. Please read my earlier posts on "education": water savings tips 3X a year in our newsletter; HOA pays for water & sewer for our 211 high rise condos with 440 toilets, so trying to find ways to save matters; no owner can be forced to update their toilets.

And finally, "The Jabberwock, with eyes of flame, Came whiffling through the tulgey wood, And burbled as it came!"

I stand by what I wobbled... A HOA can strongly suggest and educate but NEVER mandate... Unless the entire HOA and owners agree and fund the project. Good luck on you getting owners to change. I know the advantages of dual flush toilets but still not purchasing one. No need to sell me on the concept. It is just low on my priorities... 3 toilets and a septic system... Not much need in it.

I still don't get your reply, Melissa. We won't suggest the Board "mandate" that everyone purchase dual flush toilets! And indeed we can not. Why do you think that's the case??? But there are certain things that boards CAN mandate as you well know.

The proposal to the Board will to be offer an incentive, perhaps $100, to change to dual flush. The board does have the authority to approve this up to a amount that the board can determine--if it's interested. We have a few directors who aren't up to date on the newer technologies.

I got the idea from a News piece I read on this Forum back in '11 or '12. A FL HOA offered some sort of credit also for a water saving initiate. Can't remember the details though.

I'm not talking about dual flash toilets from EuropePitA, only saying that the folks there keep buying more and more and more of them.

US firms do mauf. them, including Koehler (sp?) and other well known brands

yes, us firms such as kohler manufacture them

but

imo

there is a lot of 'catching up' to do before they are TRULY cost saving

except if they are used to replace an OLD non water saving unit using 3.5 or even 4.0

said bowls would be pre 1996, likely that most have been replaced anyway by now

replacing a LEAKING or NON FUNCTIONAL 1.56 with a dual flush will save a LOT of 444

BUT

the 'seeable' savings will be because of the replacement itself, not because of the dual flush

In results from field studies using a popular dual-flush toilet with a 0.8 gallon-per-flush (gpf) and 1.6 gpf options at single-family residences, it was found that the overall average flush volume for this fixture was approximately 1.24 gpf. This volume is virtually identical to the 1.28 gpf volume rating of single-flush HETs.

Thank you so much PitA. By going to the site, I found many other useful articles because I now looked for HET (high efficiency toilet) data. I had not heard of HETs before today.

All HETs, I learned, are 1.28 gpf whether they are single flush or dual flash. More, Calif. eff. 1/14, requires that all toilets for new dwellings be HETs. And I think replacement toilets too. That part's not so clear to me. Apparently this law is coming soon to other sates, e.g., Texas.

So, owners in my condo building who replaced their toilets beginning this year, replaced them with HETs (it seems), which is good!

So, PitA's cite is: "In results from field studies using a popular dual-flush toilet with a 0.8 gallon-per-flush (gpf) and 1.6 gpf options at single-family residences, it was found that the overall average flush volume for this fixture was approximately 1.24 gpf. This volume is virtually identical to the 1.28 gpf volume rating of single-flush HETs."

So, any HET, by definition, is more efficient than a 1.6gpf. Most toilets still are 1.6gpf and any HET will provide savings over that old type. I also noticed that the article was from 2004.

Its likely you had a leaky toilet anyway. You would have those same savings if you replaced the $3 flapper at the bottom.

Did anyone else catch wanting to give a cash incentive to install the dual flush? Let us see who can post the fastest on why this idea is not good? Mmm... Hint: A HOA is only funded by its members for its members?

It is still a choice for people. The reason to choose is just the same as not choosing. I bet not alot of people want to change no matter how hard you try to convince them. I am still on a septic system and my water bill is under $20 a month. You are not convincing me and I know plumbing...

Learning from the reference that you provided, PitA, the proposal to the Board will ask it to offer the incentive for any HET that an owner installs. In both my dual flush toilets,btw, the liquid-only (aka #1) flush leaves no yellow water.

"An HOA only is funded by its members for its members." I did know that Melissa even before I ever read your many, many posts with that phrase.

It does happen, Melissa, that Boards decide to authorize spending every members' funds (maintenance fees) to yield savings. Usually these initiatives involve energy savings. They often have upfront costs even with rebates and tax credits, but those are paid back in xx months or years because of the savings.

This may not apply as often to HOAs of detached homes as, say, to high rises. But I imagine that if the HOA is responsible for the street lights, the board may want to retrofit them with LEDs, i.e., spend Members' funds. Or, I’m guessing that new sprinkler system or irrigation technologies can generate savings after the payback period. But it will take members' funds to update these.

I just noticed that this topic has had a large number of views! I don't know why because there are so few high rise posters. So maybe there're lurkers who are considering replacing their own toilets for savings and/or aesthetics. Maybe someone is willing to tell why so many views??

I'm going to summarize later what I've learned form Richard, Larry, Cecelia and PitA and from online sources.

summary:

HET = good - 1.28 / flush

Dual Flush HET = ??? - 1.6 and .08 / flush = 1.24 AVERAGE = not cost effective vs single HET
KerryL1 (California)

In high rises where the HOA pays water & sewer, there are two good reasons to install HETs: To save on water & sewer bills and to help avoid clogs.

An HET (high efficiency toilet) may be dual flush or single flush. Or pressure flush too.

HETs carry the WaterSense label, kind of like an EnergyStar label.

The savings by switching to an HET from 1.6gpf toilet is about 20-30%.

If one person uses five flushes per day, the savings with an HET will be about 300 gallons per year. For folks who stay at home a lot, there will be more flushes per day and vice versa. If the current toilet is 3.5gpf, an HET will save 4,000 gallons per year!!

HET's use 1.28gpf or less. Toilets since 1992 use 1.6gpf. Toilets prior to then use 3.5gpf up to 7gpf!

The savings probably will be less in regions where water is cheap and water & sewer costs are unrelated.

There are retrofits for about $25 at stores like Costco which convert toilet sto dual flush.

Local regions/water districts offer rebates when an HET is purchased. A district in CA, for instance, currently offers $250.

Prices start low and go waaaay up. If remodeling one or more baths, HETs in sleek styles should be a good investment for resale of detached homes.

That's all I can think of. Thanks again to those who offered helpful suggestions.

Dual Flush vs HET Toilets – (not for the squeamish)

Ok so I’m on a toilet blogging kick lately. Feel free to skip this post if you are squeamish about potty talk. I’ve talked about the Toto Aquia Dual Flush toilet on my blog in the past. I’ve probably installed 30 of these toilets in the last 6 years and they are a fantastic flushing toilet. They use .8 gallons of water on the low flush button and 1.6 gallons on the high flush button. This Aquia at my house is a powerhouse flusher and has not once clogged, I liked it for a while…. Except, my opinion of them (meaning all Dual Flush toilets) has changed after a few years. Here’s why, they have a TINY water spot inside the bowl. Here’s a photo of the Aquia in my Guest Bathroom.

It’s a nice looking modern toilet. Dual flush buttons are on the top of the tank.

Here’s a shot of the bowl, can you see that tiny water spot?

I added some blue food color drops to show how tiny the water spot is on this dual flush toilets.

It’s my opinion that all Dual Flush toilets suffer from this same issue of a small water spot. I probably don’t need to spell this out, but the issue with this small spot is that when you go #2 in this toilet your target is small. Thus, you end up streaking #2 in the toilet on dry porcelein. The initial flush will get most of this down the drain but it leaves some clinging to the bowl which necessitates using a toilet brush to clean the bowl, then hitting the flush button again. Your 1.6 gallon initial flush plus this second ā€œcleaningā€ flush using the .8gallon button means that going #2 actually requires 2.4 gallons of water use. Plus you’ve now got a yucky toilet brush with remnants of #2 attached. (Sorry for the graphic nature, but this NEVER gets mentioned and I sure didn’t know it ahead of time)
So, now let’s compare the water spot on HET (high efficiency toilets are 1.28 gallons per single flush). Here’s my hall bathroom with a Kohler Wellworth 1.28 gpf HET.

Kohler Wellworth HET. Not quite as good looking as the Toto Aquia

Look at that normal water spot. It’s HUGE compared to the Dual Flush models.

Here’s my Toto EcoDrake HET in my Master Bath. I’ve had it 5 years now and LOVE it.

Here’s the water spot on the Toto EcoDrake HET.

The photo above is the EcoDrake (see my review of this toilet) which uses 1.28 gallons of water, but the water spot looks like an average 1.6 GPF normal toilet. In the end it’s this normal sized water spot that puts these HET toilets on my recommended list. I no longer recommend Dual Flush toilets and I would be sure you know what you are getting into before buying one.

HET vs Dual Flush = HET Wins!

summary update:

HET toilet = 1.28 gal per flush

Dual flush toilet = 1.24 gal per flush

0.04 gal (or 5.1 oz) difference

negligible savings paid for by the 'visual appearance' after #2 use

IMO: HET wins over Dual Flush based upon actual functionality/cleanliness!

I've drawn the same conclusion, PitA. Single-flush HETs are better than dual flush HETs. You cited a blogger who wrote that single flush toilet are more effective with solids, but he sure didn't pick a very attractive one--there are much nicer styles out there.

We do, indeed, get occasional staining with our dual flush Inax EchoX series comfort height, single piece toilet. We do not with our single piece Fresca, which is about 2-years old now. The water comes into the bowl differently in each so maybe that matters??

I contacted our developer who just finished a couple of high rise projects in the state. He comes from the construction side of the projects and says the single flush HETs are better.

S'all for now!

After getting ideas from people on this forum, John, combined with my own research led me to the conclusion that a single-flush 1.28gpf is marginally better than a 1.24gpf dual flush toilet. The latter, though is a lot better than the 1.6gpf in most homes (in the US).

Becoming more educated is one of the great things about this site! Another point is that lots of ideas might come from other posters, but to actually learn about something takes our own initiative. & digging

history:

tank raised on wall = 5-7 gal

tank close coupled = 3.5-6 gal

water c 1.6 gal (1992 required)

dual flush = 0.8 / 1.6 gal (average 1.24)

HET = 1.28 gal (2015 CA required, probably 'the wave to come')

Steve;

to play Devil's Advocate,

not all dual flush leave streaks

having said that;

a GOOD non-streaking dual flush will save 0.04 gal / 5.1 oz on average per use

not worth the extra complexity and future repair costs vs. a HET

KerryL1;

a 'dual flush' is NOT a HET

first came 'water saver' = 1.6

second came 'dual flush' = o.8/1.6

then came HET = 1.28

Well, PitA it took 5 seconds to confirm that dual flush toilets are, in fact, HETs. This is from a British Columbia site.

"Question: What is a high-efficiency toilet (HET)?

Answer: A high-efficiency toilet (HET) is a toilet with a flush volume of 4.8 litres (1.28 gallons) or less. Dual-flush toilets are classified as HETs because the ratio of reduced flushes (up to 4.1 litres) to full flushes (up to 6 litres) results in an effective flush volume that is less than 4.8 litres."

Second, the legislation that all new toilets sold in CA must be HET became effective 1/14 (won't be '15). Texas is indeed next.

Third, I asked our lead security officer today how many leaky flappers he found by using the dye in toilets while other maintenance was done in each condo. He was writing his report when I saw him and thinks it's about 45. We have about 440 toilets in our 211 condos, here and our sewer bill is tied to our water bill.

While one HET used by two people in a cheap-water state might be pointless, a couple of dozen or more in our HOA in an expensive-water & sewer star could save us a lot.
