Cut Off Settings for Pump - Lawn Irrigation
Posted by Mike on June 22, 2003 at 09:40:29:
I have a 3 year old house which has a well system. We have a 1 hp pump and a large capacity tank (don't know exact gallon size but its one of the biggest on the market). Initially, the cut on/off PSI was 30/50. My wife was complaining about the water pressure from the shower so I bumped it to around 40/60. Water pressure seems better. However, when one of my sprinkler zones kicks on (the one farthest from house), the pump can only get to around 50 psi (so, it never shuts off on this zone). My pump usually runs for about 60 - 90 seconds on the other zones with a resting period of >2 - 3 minutes. I hate to lower the cut off back to 30/50 just for this one zone but am I wearing out my pump with this continous running? If I did lower my cut off, would adding more air pressure to tank help with pressure from the shower head?
