water pump pressure switch

[wmfels]

I have a 12v diaphragm water pump that started leaking. Don't know the brand but removed the pressure switch because its leaking. Where do I find a new switch,or replacement part?

Most hardware stores sell them. Make sure you get the pressure range appropriate for your system.

Good chance it's a par pump. Most boat stores should have the pressure switch
