On Friday, I had no water in the house. Inspected my jet pump and pressure switch. Found that the diaphram on the 4 year old pressure switch was leaking. I replaced the pressure switch with a copy - Square-D 30/50 pressure switch rated for 115 or 230v. I run it at 230V. Turned on the power. Worked like a charm for about two hours. Inspected the switch again and noted that the contacts on the switch had gone askew such that when the switch was closed the only one contacts was (well) making contact. Thought it was a defective switch. Exchanged it for a new one, replaced the defective one. Pump cycled on and off like it should for 48 hours. Inspected the switch, same problem.
Only other thing I can add is that the contacts seem to sparking a lot when the pump is running.
Better description of the switch.
Switch has 4 connections for wires. Two outer ones are connected to power. The two inner are connected to the pump. When the switch is closed contact is made by a small metal bar across the right two and a separate metal bar makes contact across the left two. In the case of the first bad replacement switch the right bar was rotated such that no contact was made when the switch was closed. In the case of the second switch, it was the left contact.
Any suggestions??
I had the first Square D switch for 4 yrs, now two bad ones? Is it my set up or maybe a bad lot of switches?
Are there better switches?
I believe the pump is 2 or 2.5 HP. Could I be pulling too much current for the switch?
In advance, thanks for your help.
