General Pool/Spa
Why is there water leaking from the backwash/waste line while I am filtering the pool?
- At the bottom of the valve is a spider gasket. This gasket seals against the valve body to divide the ports. Depending on the placement of the handle, each port is designed to direct the water flow in the appropriate direction. If the gasket swells, or becomes unseated from the channel, the water will flow in various directions. The gasket can be replaced in some models or the entire key/stem assembly will need to be replaced.
How do I replace the spider gasket?
- On all models with the exception of the 714 series, the spider gasket can be replaced. The
first step would be to GENLTY remove the old gasket and glue, ensuring the channels are clean and clear. There are two types of glues that can be used for this application, crazy glue or 3M adhesive, part number SPX0710Z9.
- 3M adhesive – Lay a bead of adhesive into the channel where the gasket sits. Place the flat side of gasket into the channel. Apply pressure to firmly seat the gasket and let dry for 24 hours.
- Crazy Glue – Use caution when using crazy glue. You will have only ONE chance to seat the gasket. Follow the instructions above for installation.
What is the difference between a CL200 and a CL220?
- The difference between the two units is how they are installed. The CL200 is installed in-line. This means that it is directly installed into the rigid PVC plumbing lines. The CL220 is an off-line chlorinator and is attached to the PVC plumbing lines through the black tubing and saddle clamps included with the unit. The output and types of chlorine dispensed are the same.
Where does the chlorinator get installed?
- It is the last piece of equipment installed in the plumbing lines on the equipment pad. It is located just before the water returns to the pool. This is done to keep the extremely corrosive chlorine water and gas from entering into the equipment.
What chemicals can I use in the chlorinator?
- ONLY Trichloro-S-Triazinetrione (Tri-Chloro) based, slow dissolving stabilized tablets are to be used in the chlorinator.
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.
