I'm having a 20x40 vinyl lined concrete wall hard bottom inground pool 3 1/2-8' deep built.
I've been given recommendations by one builder for a main drain install(extra charge it is optional) and by another not to put one in.
Is this a must have or is it unnecessary? I know the new double drains w/hydrostatic valve and special cover are safe.
I'm concerned with heat distribution and filtering. The no main drain builder uses 3 skimmers, 3 directional return jets,
and 2 deep returns. The 2 deep returns are to provide deep water circulation. I was told by him that the main drain is really only for draining
and not that effective for filtering or heat distribution, draining below the skimmer height can be done with a pump.
Thanks in advance for any advice. I want to make sure I make the right decision.
