Hayward SPX1105Z4TC Above Ground Chlorinator

What This Part Is Used For
The Hayward SPX1105Z4TC Above Ground Chlorinator is an in-line chlorinator used on above ground pool circulation plumbing. It installs in the return line so chlorine can be fed into the pool water as the pump runs.

Why This Part Matters
Consistent chlorination is what keeps water clear and sanitary between tests and manual dosing. A failing or bypassed chlorinator can lead to algae blooms and unstable chlorine levels, especially during peak heat. Replacing the unit restores controlled chlorine delivery through normal circulation.
