    Heat Pump By-pass/ two 3-way diverter valves or one with check-valve

    I have started the plumbing for by-passing the heat pump but ran into a concern. According to all instructions the check-valve should be at the lowest point of the plumbing. This is not quite possible for me because after the heater the returns then run underground. Will the check-valve work...

    Should the heat pump have a by-pass for the water

    I have a question on my pool plumbing. Should the heat pump have a by-pass for the water? My concern is that if the heat pump fails [leaks] that I will be unable to run the pump and filter. Is this something I should be concerned with and have it done? Here is a pic of my current set-up.

    Can you repair by gluing a broken pump housing?

    I just ordered a Hayward Tristar XE 1.85 THP pool pump which arrived tonight with a broken base. This pump was very difficult to find and I would like to know if gluing this back together will hold. If so what type of glue would you use? I want a Tristar pump because it would be a simple install...
