What is the difference between an inline and offline chlorinator?
 Reply

A  Answered on 1/30/2012 by InyoPools Product Specialist Patrick P.

An inline chlorinator would be plumbed directly inline with the plumbing.  For an existing pool, this would mean a section of pipe would need to be cut out to install the chlorinator.  An offline chlorinator attaches to existing plumbing by chlorinator tubing (holes would be drilled into existing pipe to attach the tubing.)

2 questions: Do I need to bleed air out every time I add tablets? The first time I used it, I filled it with water to get air out as instructed, turned on pumped then noticed a small water leak coming from edge of glass... Is this OK? I shut pump off then drained water out resealed the lid and turned it back on. Water level never came up high enough to leak water.
 Reply

A  Answered on 7/19/2015 by InyoPools Product Specialist Hector F.

It is always okay to bleed air from the system after opening equipment up. If there are leaks coming from any pieces of equipment then check the condition of parts surrounding the area as well as any seals and gaskets.

A  Answered on 6/30/2016 by InyoPools Product Specialist Alan M.

What is the results of a chlorine test on your water? The strong smell could be from an excessive amount of chlorine added to the water or from chlorine bonding to bacteria, resulting in chloramines. Chloramines form when chlorine binds to the body waste swimmers bring into pool. Here is a great link on How To Remove The Chlorine Smell From Your Swimming Pool.

After about 2 years of usage, the dial on my 25280-100 cannot be moved. The pool repairman who installed the unit said the chlorinator should be removed once a year and the dial assembly cleaned to clear out chlorine residue. I removed the unit but was unable to take out the dial assembly. The handle on the assembly is solid plastic with no apparent way to get it off. It is unlike the diagram that came with the unit, which shows a knockout plug and a screw holding the handle to the unit.

If more water is flowing into the feeder, that increases the level of chlorine in the pool, correct? That's assuming that tabs are in the feeder, of course. I think the label on our dial is backwards. It suggests that clockwise (counterclockwise) turns decrease (increase) chlorine output. Your comments and the instructions suggest otherwise. Thanks!

The lid you must the clear plastic version that will in fact cloud over after time, there is a clear glass lid option available as a complete unit part # _25280-400-000 that should prevent the lid from becoming foggy or cloudy.

My PowerClean Ultra has worked great for about 4 years. In the past week, I noticed the tube that holds 3" tablets fills all the way to the top with water when it normally is only about 4 inches filled with water. Wearing a mask, I removed the pucks and poured hot water into the tube over the grate and the water bubbles and flows out so I believe I have gotten rid of any residual chlorine grit and grime in the chlorinator. Any ideas of why this is happening and how to resolve it?

Hi Eddie, our best guess is that there might be an issue with the PowerClean Max Chlorinator Check Valve - 25280000920.  Be sure it is clean and free of debris and the seals and gaskets have a light coating of lubricant on them.  They can degrade over time.

I don't want to break anything or mess up my chlorinator.

      Unfortunately, we do not have a resource to fully answer your question. When reviewing the schematic there is a part directly under the PowerClean Max Chlorinator Check Valve - 25280-000-920 it appears that piece lifts out of the body of the chlorinator and the check valve has a lock tab to connect to it. The check valve is assembled to replace it, I attached another image of the check valve from underneath. I hope this helps.
