Does the unit come with the hose and connectors needed to hook it up?.

Cecil B on Jul 18, 2021

BEST ANSWER: Yes - all hoses and connectors you need to get it going. You still need to drill the holes if they aren't there already. Also, you'll need the anchor bolts to mount it to the cement.

does this unit come with the regulator (dial that controls amount of chlorine dispensed)?

A shopper on May 12, 2017

BEST ANSWER: Yes, the black thing you see toward the bottom on the photo is where the dial is. It also came with the tubing to connect for water to flow into the chlorinator and out into the filter/return to pool. The gasket was also included that fits inside the lid.

what would cause a water leak coming from the top of this unit?

A shopper on Jul 17, 2016

BEST ANSWER: I always keep a spare o-ring on hand. We have had them just wear over years, and we've had one get caught in the threads when replacing the lid. Once there is a crushed or flat spot, it will leak. Fortunately, they are inexpensive and easy to replace. Just put a light coat of silicone lubricant, and it should stop the leak.
