Toilets, Sinks, Showers, Tubs and Disposals - Water pressure for toilet?

I am going to install a pressure assisted toilet (mansfield quantum) and I assume I need to check the water pressure first. Can this be done with some kind of flow test in gallons per minute or do I need to put some kind of gauge on it?

What is the normal pressure in a house?

Thanks in advance,

Joe

Screw on pressure gauge on an outdoor faucet is easiest if the outdoor faucets aren't before a pressure reducing valve (if you have one). Bout $10 at any hardware store or home center.

I think most common is about 45-60 psi for city water.

Mansfield specifies a minimum static pressure of 25 PSI at the supply line connected to the toilet. The pressure anywhere else is often irrelevant and could be misleading.

To verify/validate sufficient static pressure at the supply line you'll need a large (2 - 3 gallon) bucket, a timing device (stopwatch, wristwatch, or any thing with a "second hand" or the digital equivalent), and a towel or mop to sponge up any water that may drip onto the floor while you disconnect and reconnect the supply line.

Disconnect your supply line from the existing toilet and direct it into the bucket. Fully open the supply stop for exactly 30 seconds and then quickly close it.

If you have one gallon or more in your bucket, your water pressure meets or exceeds the 25 PSI minimum requirement.

Good luck!
