What is a check-valve?
- A check valve is used to prevent water from flowing in the opposite direction. A check valve for a chlorinator is used to prevent chlorine gas from entering into the pool equipment. ALL CHLORINATORS SHOULD HAVE A CHECK VALVE ASSEMBLY.
- CL220 has a check valve assembly built into the discharge fitting. In addition, the black tubing, on the discharge side should be looped. This is called a “Hartford loop” which helps prevent chlorine gas from getting into the equipment.
- CL200 requires an in-line check valve that is plumed into the pipes. A chemical resistant check valve should be used to prevent the gases from backing up into the equipment. This is especially important if there is a gas heater.

What size pool can a chlorinator handle?
- CL200, CL220
These units hold up to nine (9) pounds of tablets. Either unit can handle up to a 36,000-gallon pool. The dispensing rate is .05-lb/per hour. The exact level of chlorine in the water will depend upon environmental conditions, water balance and bather load.
- CL220BR
This is e used only as a brominator for bromine tablets. It can supply bromine for about 24,000 gallons of water. The dispensing rate is the same, .05lb/hr, but the required level of Bromine in a pool is higher then chlorine.
- CL100, CL110
These units are designed for above ground pools. The capacity is 4.2 pounds of tablets and can handle a pool up to 14,000 gallons. Depending on the bather load and chemical balances, it may need to be run for longer then 8 hours a day to maintain proper sanitizer level.
Why is it important to use the specific Hayward lid o-ring?
- The gas inside the chlorinator is extremely corrosive. The Hayward o-ring (CLX220K) is made of a composite material with a percentage of lead. The lead enables it to be more tolerant to the chlorine gas.
Why is there so much build-up inside the chlorinator?
- All Tri-Chlor tablets are comprised with a certain amount of binding materials. (Binders are used to convert the chemical into a tablet format). Using the purest form of Tri-Chlor will ensure less build up inside the chlorinator and extend the life of your chlorinator. Consult your local Hayward dealer for chlorine options.
How do I winterize my chlorinator?
- Ensure the feeder has been drained of all water. Next remove the lid and properly dispose of any chlorine inside the chlorinator. (Consult your chemical manufacturer for the required disposal procedures).
- CL220 - Remove the lid and disconnect the black tubing from the plumbing lines. Ensure that the water is drained, and then store for the winter.
- CL200 – Remove the lid and open the drain plug on the bottom of the unit. Replace the lid and screw on loosely.
- CL100 & 110 - Dispose of the remaining chlorine per manufacturer’s instructions, drain and store for the winter.
Do I need to lubricate my chlorinator lid o-ring?
- Yes. The lid o-ring should be lubricated at least once per month to maintain its elasticity. A silicone-based lubricant should be used as it holds up better to the chlorine gas. Hayward’s product Jack’s Lube part # SP032712 can be used on all Hayward o-rings and gaskets.
What is a skimmer and what is its purpose?
- A skimmer is a suction port, installed at water level. It collects surface debris in its’ basket, as the water flows through the skimmer to the filter.
How many skimmers do I need?
- The Association of Pool and Spa Professionals (APSP) advises that there should be a minimum of one skimmer per 400 sq. ft. of pool surface area.
Where should the skimmer be placed?
- A skimmer should be placed in the path of circulating water. There aren’t any hard rules on location, especially with the popularity of free form pools.
What are float valves and equalizers?
- The equalizer valve goes into the skimmer, below the basket to balance the water flow. These are required for commercial applications in order to meet NSF code. The float valve monitors the water flow from the skimmer. If the flow is obstructed, or the water level fall below the skimmer throat, it will open the equalizer valve so water can be pulled from the main drain, preventing an air lock in the skimmer.
