Pentair IntelliChem
The IntelliChem Water Chemistry Controller automatically monitors the pool's pH and sanitizer levels and adjusted them with acid in an Acid Canister and chlorine in a Chlorine Canister.
Acid Canister
The siphon tube is inside the pump head. It runs on rollers to create suction to send acid to the pool return. They generally need to be replaced every year because they get eaten up by the acid.[1]
Acid not Dosing
The pins that the nylon rollers are riding on inside the pump head can back out about 1/8”, so the rollers are crooked and not putting enough pressure on the tube. Put them back in place and it will work fine.[2]
Tips
- keep a spare roller assembly handy as They corrode badly and stop working[3]
- fill the acid tank 2/3 acid 1/3 water. It does require re-filling more often but the equipment lasts long due to the diluted acid.[4]
