Water Pressure Tapers Off!
Ramenom

I've been having a problem with the water pressure in my house. My house had constant water pressure before I turned off the water to fix a leaky faucet. After turning the water back on the water pressure has become really low. Almost everywhere besides the fixed leaky faucet has low water pressure. It's especially noticeable when I tried to wash my clothes. For some reason barely any water comes out of my washer now even though it looks like there are separate lines running to my washer than to the rest of the house. The washer would start off a normal, with moderate water pressure but than spouts out barely any water. During that time I can hear a hissing noise coming from the pipe near the water meter. Also, I don't see any leaks coming from the area that making the hissing sound. Having the washer on causes no water to come out of any faucet too. Can anyone tell me what's causing the problem?

Thank you.

If you have iron pipes, when you turned off the main you broke rust and crust loose inside the pipe that is now causing your pressure issues. You can try cleaning out the aerators at faucets and showerheads, odds are you'll have to have the lines back-flushed.

If you have copper or pex water lines, then it sounds like there could be an issue with the main valve, try shutting it off and opening it to full open minus 1/4 turn.

It is also possible that when you turned the water back on, a seal came loose in the shut off valve and is blocking the flow of water. You might try turning the water off again and then back on. Sometimes that works, if you are really lucky that day.

Get a water pressure gauge and measure the pressure in a few locations. If you get readings lower than 40 PSI, it's your pipes.

Next, get a few plumbers to look at your system.

Personally, I think that you may need to re-pipe, if you have galvanized pipes.

How old are the pipe? Are they a dull grey color ?

FWIW you have a flow rate problem. Pressure is measured with no water flowing, at static pressure.

If there is a pressure problem, its outside the house. from whatever is supplying the water be it a well or the city.
