Dual flush conversions, Two flush.com VS Selectaflush

That's great you converted your toilets. How was the installation process for the Twoflush.com unit? I've seen the Brondell Perfect Flush dual-flush upgrade at the West Coast Green tradeshow, but I'm under the impression that unit takes some time and some effort to install. In the pictures, it looks like it probably has more pieces than the Twoflush.com unit. 

 

In any case, that's very good to know which one has been working better for you.

Dual flush toilets are definitely a good way to save water at home. Today when fresh water levels in many parts of the world have dropped alarmingly, we need to make all the effort we can to save water. In fact BeWaterWise.com also has a very good section on how to save water - http://www.bewaterwise.com/tips01.html . These tips are not only simple but inexpensive too, and can save gallons of water everyday. Please check them out and pass the word around, water conservation is very important. Without water there will be no life of Earth.

 

My personal experience with the Selectaflush is that my company sold them for a short time under the name of One2flush. Today August 3, 2009 we are still getting returns on the Selectaflush product. The heartache of Selectaflush drove me to finding a product that actually worked like it said it would as well as was easy to install and worked in most toilets. We found that product and market it under the One2flush label. We have dual flush conversion kits that fit both 2" and 3" toilets. We get no returns and best of all we are actually helping to save water. You can get them here. www.beingwater.com

I like the idea of a dual flush conversion but do you think the half flush really works as specified?  I've used a few in the past (can't remember which ones) and from a plain eye view, it didn't really look like half flush was all that different from full flush.  But maybe there's a lot of adjustment with the unit and the specific toilet?

Hi Brucebr100, Welcome to the Ecohuddle!

Can you provide some actual figures to support the claims?

It would be interesting to many people. Until there are actual figures on the table it is all talk where you have to front the money to see if it really works.

Is there any independent verification of the claims?

Thanks,
Russ
 

Russ,

Let's start with the basics.
1. Both the Select-A-Flush and the Two-Flush have rigid plastic flush arms that only allow for installation in front handle toilets. The One2flush has a Stainless Steel cable that allows installation in any type of toilet.
2. Both the Select-A-Flush and the Two-Flush are 12" tall. The One2flush is 8.5" and will fit in tanks from 9" up
3. The Select-A-Flush does not have adjustable flush rates.The One2flush will adjust to any tank. Meaning, if you have a big wide 3.5 gallon tank, you can adjust both the 1/2 flush and the full flush to get a bowl swirl while using a minimal amount of water. The same is true of 1.6 gallon toilets. These tanks are taller and narrower, so they have different flush requirements than the old toilets. The One2flush has taken this into account. If you look at one of our One2flush You tube videos , the one showing the American Standard installation, you can easily see what I am talking about.
4. We also have a unit that replaces 3" flush valves. we have installed them in Totos and Kohlers as well as Eljer Titan. In all cases. They have significantly improved the flushing ability as well as conserving water on the 1/2 flush mode.
5. The One2flush has been picked up by Ace, True Value, Orgill's, and Friedman's to name a few. And will be available this fall.
6. The One2flush won the Retailers Award for the most innovative product at the 2009 National Hardware Show.
7. The One2flush bonus pack comes with a Water Saving Fill Valve that regulates the amount of water that is sent to the bowl. Did you know that over a gallon of water can be wasted down the overflow tube? we have addressed this issue.

I know that you asked for independent testing to verify what I am saying here. We have attempted to work with Watersense but they are unwilling to test this product because of the variables that are involved with the installation in different toilets. Meaning, we can cut a 3.5 gallon toilet down to .9 gallons on the half flush and a 1.6 gallon toilet down to .6 on the half flush and still get an effective bowl evacuation. But since they are different there is no standard established for testing like there is for complete toilet assembly's.  The best we can do in this circumstance is offer a refund if our unit doesn't work as advertised. This includes shipping both ways. We have had only one return to date and that was because the 2" model did not fit his 3" toilet. This was before we came out with the three" version. If you would like real testimonials, I can supply you with those. In fact here's one that came in while I was authoring this reply.

"Didn't realize I ordered kits that included the valves but gives me the opportunity to replace some 15 year old parts while I have the tank drained. Converted one last night - took a bit longer to get it adjusted than I thought it would - but I have to say it works and works well. More 'fun with plumbing' tonight and we'll be saving water. Right now our eight year old refuses to use any other bathroom than the one I converted."

I hope this helps.

Well done Brucebr100,

You laid out the facts quite nicely for all of us. Your details sound good to me though my knowledge is less than none on this topic.

Let's see if anyone else has any questions. 

Thank you,
Russ

I had an American Standard Flowise dual flush for a week.  The postage-stamp of water in the bottom of the bowl was not aligned with, shall we say, the exit port, above the seat, which meant the porcelain took the direct hit.  So this was not a 3 litre / 6 litre toilet, it was a 3 litre / 36 litre toilet, because I had to hit the button six times to get it clean. 
Conversions may work better, because the water footprint in the bowl remains the same.  Rona (in Canada) sells a dual-flush with a conventional bowl that looks like it would do the job.
After arguments at Home Depot, they agreed to take back the AS and exchange it (no refund) so I am stuck with a Cadet3, which I would give a mark of B.
