Chlorinator (Chemical Feeder)
A chlorinator, sometimes called a chemical feeder, automatically dispenses chlorine tablets or liquid into circulating water so a traditional chlorine pool doesn't need chlorine added by hand every time.
Most manufacturers estimate this range for a well-maintained chlorinator (chemical feeder), though the real number depends heavily on usage, water balance, and how consistently it's serviced.
Routine maintenance
- Refill the tablet feeder or liquid reservoir on a regular schedule
- Adjust the output/flow dial as seasonal chlorine demand changes
- Inspect and clean the feed line and check valve for chlorine scale buildup
- Verify the lid seal and vents aren't corroded or cracked
Common issues
- Corroded fittings and lids from the concentrated chlorine gas inside the feeder
- Clogged feed lines from calcium or chlorine scale
- Inconsistent dosing when the flow dial or check valve wears out
- Cracked housing from swollen tablets or freeze damage
When to replace
Replace the feeder once the housing or lid corrodes to the point of leaking or cracking. The chlorine gas inside is corrosive enough that repair parts rarely outlast a fresh unit by much, so most pool professionals treat feeders as a replace-not-repair item once corrosion sets in.
Skimmer logs this chlorinator (chemical feeder)'s install date, warranty, and every service visit, so you always know exactly how old it is and what's been done.
See pricing →A salt chlorinator (salt cell) converts dissolved salt in the water into chlorine through electrolysis, continuously generating sanitizer so a saltwater pool rarely needs chlorine added by hand.
An automation system centralizes control of pumps, heaters, lighting, and sometimes chemical feeders through a control panel or app, and can include ORP/pH controllers that automatically adjust sanitizer and acid dosing.
The filter removes suspended debris and particulates from circulating water before it returns to the pool. Cartridge, sand, and D.E. filters all do this job with different media and different maintenance rhythms.
