Increasing Water Pressure


We have pretty good water pressure through out the house except for one bathroom. The water Pressure coming out of the two faucets and shower fixtures is minimal. How do I increase this?

Increasing Water Pressure


did you clean the aerator in the end of the faucet? did you check to see that the shutoffs under the sink are all the way open? did you remove the shower head and check for a restrictor inside it that may be clogged?

Increasing Water Pressure


If the pipes are downsized going to the bathroom, like say .. a reducer is used, there will be a decrease in pressure. Especially if this is an upstairs bathroom.

Also, if any aerators or shower heads are clogged then there will be a decrease in pressure. That is unlikely though since water pressure is fine elsewhere, but it is a possibility.

Your aerators and shower heads could be the low flow kind too and you could be mistaking the low flow as low pressure. I would definitely have the pressure (psi) tested.

A valve could be slightly closed as well. Do check all the valves in the bathroom and at the main and make sure they are turned on all the way.

As for fixes. I would replace all the aerators and shower heads with the high pressure kind and see if that helps. If none of that that works then you will have to look at pipe size.

If there are any reducers at any point where the plumbing goes to the bathroom then do remove them and run a larger pipe. If the pipe is just undersized then run larger pipes to the bathroom.

Sounds like under sized suppy lines.
If there is low flow then the pressure drops once the valve is opened.

Some shower heads have screens/flow restrictor that can be blocked

Increasing Water Pressure


I have a shower head which has an inline screen before the flow restricter which I would have to clean a couple of times a year.

When was the last time the OP drained his HW tank, could be calcium be floating around in the system plugging up the shower head and screens.

I really doubt piping size would be the issue as a 1/2" pipe 30 ft long with an inlet pressure of 75 PSI going to the second floor (15ft vertical) would be capable carrying 5 GPM with a pressure drop of only 14 PSI.

Say outlet pressure of 60 PSI at the inlet of the valve assembly at full flow rate. Most of todays shower heads are designed around (from memory) 2 GPM.

Shower heads sometimes have water savers/restrictors in them.
Shower heads also get plugged with minerals and junk just like an aerator depending on water quality

You dont seem to be reading anything here because I already addressed shower heads and aerators. Also, with shower heads and aerators that conserve water ... the flow on them is reduced resulting in an increase in pressure. He does not have an increase in pressure though he actually has a decrease. So that's not the problem. As for a clog, it's very unlikely that is the problem either since water pressure is fine throughout the rest of the house.

Please go back and reread my post because I never said you said they are. As for a clog, its very unlikely that is the problem since water pressure is fine throughout the rest of the house.

Increasing Water Pressure


I guess the pertinent question here is,

Is this an existing problem or a new problem?

If it is a new problem then one could assume that there is an issue with the point of use aerators and restrictors, which could be a result of mineral build up possibly from the hot water tank.

If this is an existing problem, never had good pressure, then there could be an isolation valve on the main leading to this bath room (such as required in a (2) story structure) which is inpeding flow,

or if galvanized piping, could be a blockage again from mineral deposits,

or piping which not large enough for the desired flow.

I guess we will just have to wait until the OP returns and provides more information.

If the pipping is blocked from crud, corrosion, lime, rust, etc.. whatever, then why are all other pipes in the house not blocked?
