Hi All, The system I have consists of PGP heads 4 per zone and supplied by 3/4 copper to 1" funny pipe. Anyway, the static pressure in the area is 40psi and I have an operating pressure of 32psi. Pretty low static and the municipality states it's "normal" I was thinking of adding a Davey booster pump to increase the operating pressure to 45 to 50psi. What are your thoughts on this idea? The main reasoning is to obtain a bit more throw and better dispersion. Here is some info on the pump system (HS18-30HT1), http://www.daveyusa.com/hsinfo.html I can plumb it in no problem but I honestly don't fully understand how flow is affected once the pressure increases or if I'll have a suction effect off the city supply. Thanks for any tips. J.
