Because of plumbing set up the best and easiest place to install whole house filters is between the well and pressure tank. Which means ball valves in the line. I am looking for a high pressure cut off switch that will cut off electricity to the pressure switch on the tank in case pressure on well side of filters gets high for what ever reason. Would like something without automatic reset. I would rather reset it manually. Need one that would cut off power at about 80psi. Can someone throw me an idea where I could get one and name of product? Thanks for any help.
