Im having to replace pressure switch every few weeks to a month where flow eventualy just stops where switch fails. is the reason that the switches keep breaking because i dont use a flow controller and just use a shut off valve, the switch clicks constant whislt in use, is this normal?? Never had this problem when had varistream controlers.
Also does it matter what connection i attatch to on shureflow?? I always connect to the top connectorwhich is the live im guessing then also the bottom connector never the middle 1.
Other vAn has flowjet and never have any probs with that.

Help or advice would be great.
Cheers.

Have you tried adjusting the pressure cut-off by turning the grub screw on top of the pump?
Sounds to me that the pressure cut-off setting is wrong, as it shouldn't be constantly cycling on and off like that.
No wonder the switches are burning out.
Another way is to add a relay to protect the pressure switch as recommended by Peter Fogwill, although I've never really had to do that myself.
There's definitely something wrong if you are constantly burning the switches out!

Grub screw??
Do i have to take anything apart to get to grub screw?
I only know of the 3 screws that take the switch housing off.

There should be a small grub screw on top of the pressure switch housing.
You need a small allen key (2mm I think?) and by turning the screw you can raise or lower the pressure cut-off.

adjust it while the pump is running, turn it until the cycling stops, can't mind what direction
