Last year I drove a 2" well point to service a single hose bibb. The primary purpose of that well is a drip irrigation system for 12 fruit trees and 18 blueberry plants. It also now serves about 250' of soaker hose for a sweet corn patch.
The pump is a Red Lion RJS-75-PREM with the integrated pressure switch. As it was only feeding a single bibb I installed the pump to the top of a 7 gallon pressure tank. When it was first installed I found that when the orchard watering timer would come on the pressure drop was enough that the pump would kick on but the pressure switch would chatter. I imagine this is because of the large amount of water from the pump trying to get through the 3/4 pex and then almost instantly filling the pressure tank. I was able to fine tune my pressure switch to stop this behavior.
However, this past summer I had to add in a couple of motion activated sprinklers to keep the deer away from the squash my wife added. They each fire for up to about 10 seconds which causes the same issue I had before where the pump switch chatters.
I have thought through some possible solutions but I wanted additional input from the more experienced:
1. Move the pressure switch pick up so that it does not come off the housing of the pump. I imagine if I move it down stream away from the instantaneousness of the pump kicking on that might work.
2. Add in a second tank to the system. A larger amount of water to displace before the pump cycled would I imagine help. There isn't a ton of space in the current installation location but I imagine I could work something out.
3. Swap out the pressure tank with a larger unit. Same rationale as above.
What say you experts?
