HaywardCL110 Off-line Automatic Chemical Feeder,Black

The Product was an easy install. Took less than an hour and is working great. The install time includes building an elevated position so that the unit's top sits above the water level. The input tube was installed where the line from the pump goes into the filter head. I put the output on the return fitting at the pool.The one negative I saw in many other comments was how hard it was to remove the cap to add more chlorine. I suspect they are tightening the cap too much. This is an O-ring seal, which doesn't need to be tightened hardly at all. The pressure in the unit will cause the o-ring to deform sealing it. Once the pump is turned off the pressure drops, the o-ring goes back to its original profile. Just put the cap on until it touches the o-ring and then maybe tighten another couple of degrees. If you are worried about a leak, just turn the pump on and look. If its leaking, very unlikely, then turn off and tighten just a little more. I've added chlorine 4 times so far and it has been finger tighten off and on. No wrench or pliers needed.

Fast, easy install and works great. Couldn't be happier.

Works great, saves chlorine tablets although requires flow adjustment seasonally based on outdoor temperatures.Taking one star away because the black tubing became brittle and cracked after only one season. When trying to replace, the plastic tubing connector also broke.Here’s the important part: do yourself a favor and before you install this, buy from Amazon 8mm OD x 6mm ID PTFE tubing (yes PTFE, not poly or any other material) and use instead of the black tubing that comes with the unit. PTFE is UV stable, does not react with Bromine or Chlorine, and won’t crack under low temperatures. It’s the same material used to insulate cabling on the space shuttle and the tubing is widely used for 3D printers so it’s not that expensive… but it will save you from having a leak down the road.One note: I don’t know why the price went up so much in one year. I paid around $54 in Sept of 2022.

I've had this product before and it is so easy to use. Monitor your pool's chlorine levels. If the level is too high, turn the dial down on the chlorinator. If the level is too low, turn the dial up. What can be easier than that?!

Very difficult to use as the lid is extremely difficult to open and it did not allow chlorine tabs to dissolve properly. Poor build quality.

Fast delivery . Perfect clorinator with all the pieces and parts you would have gotten brand new . Awesome deal thanks !!!

This is my 3rd one in 5 years. The top gets very difficult to open and eventually the product cracks around the hose connections. I have tried every recommendation to get them to open easier but none of the ideas have worked. The "o" rings must be expanding. Either way, the product does not last long but it does work great.

It keeps the chlorine at a good level. Slight adjustments are needed every now and then. I used to put some chlorine in the skimmer. Using the Hayward auto chemical feeder is not only easier, but uses a lot less chlorine. And now I don't have the chlorine spikes I used to have.
