    Default Low water volume problem from municipal water supply

    Is there any way to increase a low water volume problem from municipal water supply.

    Pressure is not an issue, it is simply the volume of water we are getting that is a problem. You can barely run a faucet if you have the shower going. Pressure was tested from the main to the house and all is good in that regard. Town is unwilling to help any further. Anything else that could be done on my end?"



    By the way the house was but in 2001...so all copper piping. All valves were checked to be fully opened, and the water was bypassed to test as well.



    Looking for some other alternative to increase water volume, if that is even possible.



    Thanks in advance !

    How was it tested? Simply reading a pressure gauge in static conditions is meaningless if there is an obstruction between the city supply and your home. The pressure will be fine, right up until you start flowing some water, then it will plummet and the flow will be low. What matters is the combination of flowrate and pressure.

    Get a test gauge ($~10 at a big box store) and see what the pressure in your home does with any flow. If you have a PRV and hook up on the city side of the PRV then can tell you if the pressure is falling on their side with flow. The problem could be your PRV.

    Is this a recent problem or has it always been like this?

    What is the diameter of the pipes:

    1) supplying your meter

    2) running from the meter into your house and supplying the various fixtures.

    If your pipe is under-sized, then that may be the problem.

    If you have half inch pipe supplying too many fixtures, then increasing the diameter of some of those runs may help. Generally, you want 3/4" to the bathroom, then reduce to 1/2" to each fixture.
