Using gravity flush on a flushometer bowl

[Dadnoz]

is it possible to use a tank on a bowl specified for flushometer use? the tank would need to have sufficient capacity of course, but are there other considerations?

Wanting to revert a 2 piece 4 bolt wall mounted toilet back to an in wall tank as originally installed circa 1960.

Considering a Kohler K-4323-0 bowl (or similar) with a Geberit 109304005 tank.

Thanks!

If I wanted to get a Flushometer toilet working in a home with normal plumbing, I would consider using a precharged pressure tank, as are used with wells. Maybe a 20 gallon tank, which can deliver about 5 gallons. A smaller one may work.

In the realm of possible, you could upgrade your home plumbing size to not require any tank to support the flow rate needed. People sometime replace their service line from the street for various reasons. If you were going to do that, perhaps because you are doing and addition or your existing line had some failure, you could upsize the service line size at the same time.

I am not saying your proposed method is impossible, but it seems less probable.

Thanks! Will research the pressure tanks. My incoming service might be sufficient as the builder had installed a 1 1/2” fire hose in the basement! Will check the possibility of running a 1” supply to the toilet as well.

I think you are liking the flushometer for decor reasons. If your objective is just a wall hung toilet, there are in-wall tanks and toilets that are made to use those.

Those bowls need a huge amount of water for a short amount of time, which is why they need a large supply line and enough pressure behind them to work.
