I have been noticing a trend with the acid injection pump heads on these units.
They seem to be lasting only 3 to 4 months. Pentair has been good with replacing them, but after warranty is up that can get a little pricey.
I have also noticed a back flow of pool water into the acid tanks after a period of time.
Has anybody else been having issues with these.
Trying to collect as much info as possible.
