can I replace my ph. sensor switch. controller will not open feeder unit to raise ph. levels even tho the readout is below set point ?

A  Answered on 4/20/2017 by InyoPools Product Specialist Scott W.

I do not have any replacement parts information for that controller. I would give Pentair a call, 800-831-7133, to get a part number from them for the part that you are needing.
