    Very low water pressure to toilet
    We have taken the valve off thinking maybe that was the problem, it wasn't. With the valve off we turned the water on to the house and there was very little pressure. The sink and shower which is positioned on each side of the toilet gets plenty of water pressure. What could be wrong?

    Please help.

    Hi Tom,

    I have the first diagram, it is a fluid master, it has been changed twice, so we moved towards having a bad valve, neither of them show to be the problem. We had the valve off the CPVC line and turned the water on at the main shut off to see what kind of pressure we had without the valve. The pressure was very little, no force what so ever. The water coming out of the pipe was only about the radius of the pipe. Any take on this problem? We just bought this house less than 3 months ago, the house is on a slab and 12 yrs old. Every water spickett, shower, sink, and other toilet have great water pressure, we are clueless on this one.

    Thanks for the help,
    Melinda

    Is your water system one that uses a manifold. That is, where the water comes into the house is there a pipe with a lot of service lines going off to different fixtures? Some have shut off valves for each line, some do not.

    I am not sure, we are on city water/sewer and the house is on a slab. I haven't seen anything such as you described in the garage, is there another location it might be?

    Not sure if this is the manifold as you described, I was thinking it was our irrigation system. New to this... Sorry... :confused:

    Not likely to be in the garage unless you have a heated garage of live where it never freezes. Be where you turn the water to the entire house on and off. Since you have removed the stop valve underneath the toilet and there is no pressure on the open pipe there has to be a restriction somewhere in that pipe. That restriction is most likely to be at a valve. Can you trace the pipe back to the main pipe coming into the house?

    Ifirst thought of a bad seal but Harold's correct. You have a blockage somewhere in the branch. Is your house completely piped in Plastic or is this a repipe job? Has the pressure always been bad at the toilet? Did it ever fill good or was it like that when you bought the house? Back to you, Tom

    HI Tom,
    We bought this house in March, the toilet has taken at least 15 minutes to fill the tank. My husband and I are stumped! I only see CPVC throughout the house. I am not sure how long it has been this way before we bought the house. The reason we are stumped is that the sink, toilet and shower plumbing run along the same wall with the toilet in the middle of the sink and shower, both the sink and shower have great water pressure, but the toilet is a sad situation. This bathroom is the guest/kids bathroom, I am very anxious to have this fixed as we are going to have several guest over this weekend. Any ideas on what to do? My husband says that he is not going to rip out the wall. I tried to submit a picture, but the file was too large. Thanks again,

    Melinda
