Sloan valve with 3/4 inch service

I would like to install a Sloan type flush valve for a toilet application in my house. My understanding from reading the instructions for the sloan valve is that it requires a one inch inlet service to operate properly. My house service is only 3/4 inch. I had a brain storm that perhaps I could use a well pressure system tank with a one inch outlet to get the proper pressure and flow to work with the sloan type valve I would prefer to use. Otherwise, I might have to go with an old fashioned high tank flush system.

If you have room close to the toilet to install the tank, then it "may" work, but it is not a given, because we do not know exactly how you will do the rest of the piping.

Check the specs on the Sloan valve. While it flushes 1.6 gallons per flush, like any other toilet, the INSTANEOUS flow rate required is very high. This is why pipe size is more important that static pressure available.

You could use a 1" x 3/4" brass bushing. Like the other's said, the volume might not be there.

You would need an expansion tank very near the toilet, with 1" pipe dedicated to the toilet only from the tank. That may work.

Sounds like a lot of work to make a commercial valve work in residential.

Sloan also makes a in-tank Flushmate for toilets.

Or any of the newer toilets with 3" (+/-) flappers work very well.

People that have used the Sloan Flushometer commercial valve with standard residential piping systems, have been very sorry they went that way.

In commercial use, we often have a 1.5" or 2" water meter.

Sometimes I bring a 2" line through the bathroom core, and tee off with 1" supplies for the toilets.

I was in a lery large church in Puyallup once, that had been undersized, and really nothing worked very well there.
