What to do if Pentair Water Filtration Systems fails to regenerate?
If your Pentair Water Filtration System fails to regenerate, it could be due to a few reasons: * Interrupted electrical service: Ensure permanent electrical service by checking the fuse, plug, and switch. * Defective timer: Replace the controller. * Power failure: Reset the time of day.
Why is my Pentair Water Filtration System producing hard water?
Several factors can cause hard water with your Pentair Water Filtration System. It could be due to an open by-pass valve (close it), lack of salt in the brine tank (add salt, keeping the level above the water), a plugged injector screen (clean it), insufficient water flowing into the brine tank (check fill time and clean the brine line flow control if plugged), a leak at the distributor tube (ensure the tube isn't cracked and check the o-ring and tube pilot), or an internal valve leak (replace seals, spacers, and/or piston).
