Hayward SPX1091Z7TC Above Ground Chlorinator

What This Part Is Used For
The Hayward SPX1091Z7TC Above Ground Chlorinator is an in-line chlorinator used on above ground pool circulation plumbing. It installs in the return line and feeds chlorine into the water as the pump runs.

Why This Part Matters
A working feeder helps keep chlorine levels steady without constant manual dosing. When a chlorinator leaks or stops feeding properly, water can turn quickly during hot weather and heavy use. Replacing the unit restores controlled chlorine delivery through normal circulation.
