Hello all, yet another question or two:
When plumbing suction, I have read somewhere that you need to plumb them in a ring so that all suctions are feeding off the same line such that there is no difference in pressure. Does this also apply to returns?
On a 12-15k gallon pool is adding a floor return at the deep end wise? Does anyone know what the costs are of this type of return vs in wall?
For safety should you insist on dual main drains? (anti-vortex in case one gets plugged)
