toiletI got an email asking about low water pressure as the toilet was filling. This can happen and it can be easy to fix. If it is the toilet that has low water pressure, in other words it is taking too long to refill, there are a few quick things to do.

\

First, make sure the angle valve to the toilet is fully opened. Follow the water line from the tank to the valve. Turn the handle counter-clockwise until it stops, and the valve should be fully opened. If that doesn’t work and the rest of the house has good pressure, it may be an issue with the angle stop or supply line itself. Remove the supply line from the fill valve at the bottom of the tank and point it in a bucket. Turn the angle valve back on and see if you have strong pressure.

If the pressure is low, I would replace the angle valve and/or the supply line. If the pressure is strong, I would replace the toilet fill valve. Fill valves fail and replacing it will insure you have a good flow of water if the water pressure is good.

Much of the detective work here involves isolating the problem. Like any solution, you have to get to the root problem in order to solve it.
