Guest guest Posted January 16, 2007 Share Posted January 16, 2007 I'd probably go with a Relief Valve at the end of the line. The pump runs continuously and you set the Relief Valve setpoint 10psi less than the pump's highest pressure (which it instantly reaches if all the valves are closed). So when no valves are open, the relief valve lifts and discharges back into the pool, keeping the pressure stable and the pump happy. When one or more valves open, the pressure will drop and the relief valve will close when if it drops below the "blowdown" point.There are lots of relief valve types. Some work electrically and need a pressure sensor to control them, others use a smaller pilot valve to control the bigger valve, and some are just plain spring loaded lift valves (like the one on my pool cleaner outlet). Not all relief valves can handle long term relief. Link to comment Share on other sites More sharing options...
Guest guest Posted January 16, 2007 Share Posted January 16, 2007 Yeah, that would be better for larger systems (10+ heads). The ones professional water displays use are the same, except with an adjustible output. Link to comment Share on other sites More sharing options...
