The Hayward Chlorinator is the most recognized pool chlorine feeder on the market.
Hayward chlorinators have been around since the 70’s, in the same design, and one could say it’s America’s favorite pool chlorinator.
If you use Trichlor tablets or sticks, the safest, easiest and most accurate way to slow-dissolve them is with a chlorine feeder. A pool floater can get stuck or flip over, and putting any type of pool chemical into the skimmer is a big no-no.
Aboveground or inground, all pools that use chlorine tablets, should also use a tablet feeder, like the Hayward Chlorinator.
Hayward Chlorinator Installation
The CL-220 (or CL-110) are for off-line installation. The feeder base is screwed to the floor, and hoses carry water in and out of the feeder, pushing chlorine through injection fittings in the pipes.
In-Line Hayward Chlorinator Install
Hayward CL100/CL200 are designed for permanent installation to PVC pipe or hose. Both feeders have 1.5″ female threads to connect to a hose adapter (above ground pools), or a 1.5″ male adapter. You can also buy the optional Hayward SxS Unions, connectors to match 1.5″ PVC pipe.
In-line chlorinators must be installed after the filter and after any heater. They should be installed at ground level to prevent back flow, and if you have a heater, a one-way check valve should be installed between the heater and the feeder, to prevent damage from corrosive chlorine gas.
- Shut off pump and open air bleeder to drain pipes.
- Locate section of pipe to cut, measure twice and cut, twice.
- Thread 1.5″ adapters (2) fully into feeder, sealing with Teflon tape.
- Use PVC Primer and Glue to connect pipes to adapters.
- Fill with America’s Favorite Chlorine!
Off-Line Hayward Chlorinator Install
If you don’t have the 9″ of clear horizontal pipe, close to the ground available to hard plumb the CL200 chlorinator, you can install an Off-Line CL-220 model. No plumbing involved, but you do need a power drill and a 3/8″ drill bit for the injection fittings.
Securing a Hayward chlorinator into a concrete floor with anchors and screws is recommended, to hold the body stationary when you remove the lid. An alternate method is to fasten the feeder to a hefty piece of pressure treated lumber that is pegged into the pad.
- Secure the CL220 feeder to the pad or hefty length of lumber.
- Mark the Inlet and Outlet locations for the hose fittings.
- Drill 3/8″ hole at marked locations, clean holes of any burrs.
- Install hose fitting/gasket and clamp firmly to pipe.
- Connect feed hoses, cutting off excessive excess.
- Fill with slow dissolving Trichlor tablets or sticks!
Hayward Chlorinator Maintenance
The Hayward Chlorinator is a workhorse and doesn’t need too much attention to keep plugging away. Here’s some items that may need attention from time to time:
Clogged Chlorinator: A cheap chlorine tablet can leave behind a crusty, goopy residue. Do not use any solvents or chemicals to clean, which can cause a reaction. Use only water to flush out the feeder. For Off-Line models, a new Check Valve & Inlet Fitting (CLX220EA) is in order every few years, to keep water flowing properly. Also replaceable is the internal standpipe or feeder pipe (CLX200H).
Stuck Chlorinator Lid: The Hayward Chlorinator has a unique internal o-ring, made of Viton, a chlorine resistant rubber. It can grip very tightly, and if the base is not anchored tightly, be almost impossible to remove. There is an aftermarket lid wrench available, or removal tool.
Lid O-ring Replacement: The Viton Lid O-ring mentioned above? It needs replacement if it becomes distended or pinched. Remove the logo cap to get at the screw to separate the inner top and o-ring from the outer top. Lube your chlorinator lid o-ring (CLX200K) regularly to keep smooth operation.
Hose Replacement: Although the black poly hoses used for the Off-Line CL-220 model are UV resistant, they don’t last forever, especially in strong sunlight or freezing winters. Fortunately, you can buy an 8′ replacement chlorinator tubing (CLX220J), or the Accessory Pak (CLX220GA) for hose, clamp, nuts and fittings.
Winterizing a Hayward Chlorinator: For safety’s sake, please remove all tablets and rinse the inside with clean water thoroughly. Do not replace the lid for storage, chlorine residue may continue to gas off. Store open in a cool, dry area during periods of non-use, or just remove the drain plug and leave it connected for winter.
