    I got everything set up and it seems to held 5psi for about 15 to 20 min then it dropped 1 to 1.5 psi after 30 mins. Should I worry about this at all or is it fine since it did not drop in the first 15 minutes?


    Thanks

    You have a leak. Can you fill with water?

    if the pipe will not hold the weight of a water test, it is not installed correctly
    pvs should be supported every 4' and on both sides of each fitting

    Where I plumb from, drainage pipes must hold a 3m column of water for 15 minutes.

    If the supports holding the piping will not support the weight of the pipes filled with water, it must be re done.
