Do you have a leak on your pool chlorinator? This is a common problem that can be solved by checking your chlorinator o-ring. This Hayward chlorinator is notorious for leaking around the lid once the o-ring fails. If you have a chlorinator that looks like this expect to change this o-ring once every 6 months.
To check & change the o-ring:
1. Take the lid off the chlorinator (sometimes it will be locked down and you will need a big pipe wrench to move it.)
2. On the top of the lid is a little disk. Use a flathead screwdriver to remove the disk and you will see a plastic nut underneath it.
3. Use the same flathead screwdriver to remove the nut.
4. Separate the cover from the cover cap. This may be difficult if the o-ring gets jammed between the two pieces. You may need to use the screwdriver to pry them apart. Be careful not to break the plastic pieces.
5. Check the o-ring for cracks and make sure that it sits snug around the cover.
6. Replace & lubricate the o-ring with a silicone based lubricant. Do this once a month or when the cover becomes hard to unscrew.
If you have a Hayward chlorinator I would suggest buying a couple of these o-rings at a time because you will be changing this time and time again.
We install chlorinators but I steer clear of Hayward chlorinators because they give our clients more trouble than some other models that are out there.
A couple of my favorite brands are the Rainbow Lifeguard chlorinator and a beefier model made by a company called CMP that are great for any poolcare Orlando needs.
