Very good, but like everything, it wears out over time.
This is my second CL220 Hayward Feeder. The first one lasted about 10 years before the dial that controls the flow of bromine started to become inaccurate. Hopefully I can get another 10 years or more out of my second one. Also, over time the top lid became very difficult to open. They sell a plastic wrench to assist in opening the lid that I would recommend once it becomes stuck or hard to open.Read full review

Hayward CL220 Off Line Chlorinator Chlorine Feeder
This is an excellent Chlorinator for our above ground pool I recently found out that you should change the O-rin inside the chlorinator cover every 1 to 2 years to make putting the cover on & off easy. If you don't change the O-ring it may be virtually impossible to close the chlorinator coverf completely.Read full review

Hayward CL220 Pool Chlorinator
This Hayward Chlorinator was easy to install but I am a little disappointed that they removed the drain plug in the bottom of the reservoir.

As a swimming pool service technician, I have been installing these Hayward chlorinators for 30 years. It’s the only chlorinator I use. Excellent prod

Will Last a Few Years Then It's Time to Replace
This is a replacement for the same Hayward Chlorinator that I've had for several years. After a number of years opening and closing the chlorinators becomes harder and harder. You can replace the o-ring in the cover which helps for a while. However the chlorine seems to do something to the plastic that the affects the threads on the canister or the lid and I've found the easiest solution is just to replace the feeder.Read full review

Product is OK
I would have given it 5 starts but gave it 4 because the valve the regulates the flow from the chlorinator to the pool is basically functions like an on/off switch. There is almost no variation of flow. If the flow is set low (like I would like to adjust it too) when I check it a day later there is no flow at all--and no chlorine going into the pool. The flow valve design needs work.Read full review

Good
Very easy to install and works great, only needed a 3/8" drillbit and regular tools

better than non-Hayward chlorinators
The brand name Hayward chlorinator provides better service life than the knock offs. The lower price of the knock offs is not commensurate with their quality compared to Hayward.

Chlorine feeder
Works great, you can really load it up with chlorine tablets and regulate the amount that goes into the pool. It should last 5 + years before it will start to clog up.

install one for easy maintenance
I've only used Hayward chlorinators for our pool over the past 30 years. They do eventually fail and need replacing but when working properly it is a relief to know the pool is automactically being chlorinated.Read full review
