    What size pipe??

    So 1 1/2 inch pipe is the standard correct? I told my builder I wanted 2 inch pipe and he said it was NOT needed?? I think he is mistaken?? Anyone? I also want a variable speed pump.

    It may not be needed, but only cost a little more, and will likely save you some electricty over time due to lower head pressure on the pump.

    2" pipe certainly isn't "needed" in most situations, but it is nice to have. It will improve the overall efficiency of your system by several percent, which can add up in electrical savings over the years. Plus, as Isaac-1 said, the additional cost is so small that it is a guaranteed win in the long run.

    The "standard" has been moving away from 1 1/2" pipe towards 2" pipe for years. These days more pools are built with 2" than with 1 1/2", though there are still plenty of 1 1/5" pipe pools built.

    One caveat.....regular size pool, correct?

    If it's a 5k pool, PB is right!
