I have a drilled well which is 500’ deep with a 1 HP pump and a Wellmate WM-9 which is rated at 100 psi. My pressure switch is a 60/40 and I want to increase the pressure for sprinkler systems I’m installing. What’s the highest pressure I should go to ? I was thinking 50/70 or 55/75. I have both copper and PEX water lines installed in my house and the house was built in 2004 so fairly new. Also if I raise the pressure on the switch should I also increase the bladder pressure in the tank to 2 pounds lower than kick on pressure?
Thanks for any help
