Just reading Hydraulics 101stckey and I have a question about this statement:
"Also, when designing a plumbing system, it is a good idea to have a separate suction line from each skimmer and/or main drain pair from the pool all the way to the pump. This keeps the suction head low so the pump basket will not draw in air."
Do I understand this to mean that instead of connecting a skimmer/drain together at the pool end with shut off valves and a Tee Fitting to a single suction line (a single 30' run of pipe) to the pump, that each skimmer/drain line should have its own dedicated suction line and shut off valves from the pool to the pump location and there, at the pump end, it is combined together with a Tee Fitting to single line into the pump? If my rough distance was 30', at each skimmer/drain location at the pool I would have the connector from the pool to a shut off valve, then each would have 30' (2- 30' pipe runs side by side of return plumbing to the pump pad) which would be connected by a Tee Fitting and a single line into the pump? Does the same apply to return lines?
So, if I had 2 skimmer/drain connections and 2- return connections at the pool, that I would run 2 - 30' suction lines and 2 a 30' return lines. (120 feet of piping to and from the pump pad to the pool). I would put 2- shut off valves at the pool end and connect the 2 suction lines into 1 at the pump pad. The same applies for the return lines?
My friends these are the questions that come up when you give an upholsterer too much information...
