When i first bought my house my jet pump was fine, but now it would never shut down. My brand pump is a Myers like a SW Series like the pumpandtankswebsite.com. I would have to turn off the pump just so it would not over heat. The PSI would go up to 52 maybe a little more or less. When its turned on water works fine with normal clear water and pressure however the jet pump won't turn off when not needed. Also it has be dripping water once in a while. Any suggestions? Thanks
