CT pump guy
I have to work on variable speed systems at client's homes as a technician. I have 3 current systems that are experiencing greater than normal pressure drops before the well pumps turn on to build the system back up to pressure. On one a subdrive system I'm experiencing an 8 pound drop. On another a balance flow system I'm experiencing a 10-12 pound drop, should only be 5 psi. On the 3rd a Grundfos Sqe system I'm experiencing a 20 to 40 psi drop before the pump starts, but once it starts it delivers 60 psi consistently until I turn off the flowing water and the it build to 80 psi until it turns off. This system is only set for 60 psi. All 3 systems have tank pressure set at 70% of operating pressure. On the Franklin and Balance flow system I've already changed transducers and moved them to the far side the tank tee's. Same results. What do ya guys think, try new panels or what.
