Conservacap Use with A-36-A (4.5 gpf) Kits

Any problems using Conservacaps with 4.5 gpf kits.  If not, what is the amount of water savings per flush?



NO PROBLEMS WHATSOEVER !   Keep in mind that Conservacap shortens a flush cycle about 22% (ie .75 gal savings on a 3.5 gal flush).   A 22 percent reduction of 4.5 gal is right on 1 gal per flush savings.

Also, keep in mind that there is a tremendous amount of redundant water use built in those 4.5 gpf kits.  Most toilets will flush with almost half that amount of water use,  which is why the 4.5 gal kits today can be converted to use 3.5 gals by just turning the flow ring over to expose the rough surface instead of the smooth side.  That little trick will save a full gallon of water per flush right there.  Then add the Conservacap and you are saving almost two gallons per flush.

NOTE:   Not all of the  A-36-A kits have the water saving conversion factor built into them.   Not long ago, I got a call from a fellow who said he worked in purchasing for the GSA in Chicago.  He asked about using Conservacap with his 4.5 gal kits and when I mentioned saving water first with the conversion and then using Conservacap, he told me that his kits were older and they didn’t have that feature available.

“That’s too bad,” I told.  “How many of those older kits do you have?”

“Millions,”  he said.

We are still waiting for that order…



Will Reduced Water Use Affect our plumbing system?

This is the only note I have ever sent this Simbach guy.  And notice that it was back in Feb, before I left for Australia.   They didn’t fire that plumber because of this.  They fired him for putting 4.5 gal kits in all of the 1.6 gal fixtures.

Fixx it

Your plumber is either out of the loop or he is lazy.  Take your pick.

Since many of us plumbers are lazy,  I’m incline to think it is the latter.  To us, less water could mean more work (maintenance), so many plumbers are reluctant to buy into any thing that saves too much water.  There have been thousands of Conservacaps installed in fixtures all across the county and I have never heard anyone say that they didn’t produce enough water to keep the lines clear, so your boy is all by himself….for the moment.

If you want to see a complete turnaround and change of attitude, tell your plumber that since the water saving caps won’t work for your facility, that he should start getting price quotes on new Sloan and Zurn flushometer 1.6 GPF low flow toilets.  Also, ask him to provide you with a timetable for how long it will take him to install all of the new fixtures.

“Glory Be!” he is going to tell you within a week’s time.  “I’ve retested those water saving inner caps…and now they seem to work just fine.”  This has happened with us more than once.

Good luck and write me back if any advice I ever give you works.  I don’t want to hear about it if it doesn’t.

Hey Frank:

Thanks for the advice on using moderators over aerators in our common area sinks.  We installed the .5 GPM and they work like a charm.

Another questions please.  Several of our off campus buildings  recently installed Conservacap in their flushometer fixtures and are impressed with the water savings and like the performance.  I gave our plumber here some of them to try in our main building and he tells me that they didn’t work at all (caused stoppages, etc)  and that he really doesn’t want to use less water in our facility because of the building’s age.   Our building is newer than the other facilities where the caps seem to be working well.  I don’t understand why these things won’t work for us here.

Please advise
