Split from self-cleaning-pool-problems-t55414.html Butterfly
I've also got the Paramount 6 port system that's performing below standard lately. It's about 8 years old.
I opened the module housing and don't see anything obviously amiss but, one comment caused here me to pause; how freely should the impeller turn? I can move it with my finger but not what I'd call freely.
Also, when I opened it there was some built up calcium, not a lot or enough to look like it would impede movement. But, is it possible there is build up I cant see and maybe that's binding the impeller a little? Can it be cleaned with an acid bath?
My next step is obviously to pull the nozzles and see if any need replacement...they are rather expensive so how will I know if one is bad?
Thank you in advance!
