    Low water pressure in entire house except bathroom.
    The other day my parent's noticed water was coming through their tiles in the downstairs bathroom. After a plumber came over, he turned on the water upstairs and listened to the walls and detected a leak. He cut open the wall outside the bathroom and revealed a pipe about 3 feet up that was spraying water. He said he could tell by the amount of ' gunk' on the elbow joints that this was a problem in the past for previous owners. He replaced the pipe, put more " gunk " on and now it no longer leaks, but a new problem has developed.

    The entire houses water pressure is down drastically- Except for the bathroom that is directly adjacent to the water heater in the garage.. Every bathroom and sink has lower pressure, including the rooms he did not visit and did not touch.

    Before the plumber game, the pressure was fine - even with the leak- but now it's not. The only things he did was fix/ replace the pipe, and do something at the water heater- Which I'm assuming was to shut off and open the valves at some point.

    The top valve ( the red valve in the picture) is open - so the pressure isn't being stifled there- which leads me to the pipe he fixed ( pictured)

    Can anyone think of any things to check for why the pressure is all of a sudden so low immediately after he fixed the leak? I'd really appreciate your help. I've included some pictures in case that might help.

    I will be contacting the plumber tomorrow to have him come out again if It's not something simple but I thought I would ask here first to see if someone might have some ideas..

    Thank you
    -Mike

    Hi Mike

    Remove the aerators from the end of the faucets and clean them... could simply be some sediment got kicked up when the cold water main got shut off to do the repair work. Of this repaire the faucets, remove the hoses for the back of the washing machine as well and clean the screens there...

    Back to you...

    Don't forget to remove the aerators and check the screens for debris and trash . Open the valves and flush the lines. If there is still a problem you may have picked up debris in the cartages. If that is the case the cartages may have to be pulled and the entire system flushed. Let us know what you find. Good luck, Tom
