What is the difference between an inline and offline chlorinator?

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.)

Can the Powerclean Ultra chlorinator be used on a home water purification system?

A  Answered on 2/28/2013 by InyoPools Product Specialist Patrick P.

I wouldn't recommend using the Powerclean Ultra chlorinator on any system that has pressure above 35 psi.

Yes you can use Chlorine Sticks instead of Chlorine Tablets in this chlorinator.

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.

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.

My Pentair chlorinator had a dry-rotted hose which was leaking

Written on 9/6/2021 by Guest

The removal and installation was simple.
Tools needed: Hacksaw, measuring tape, Sharpie marker, Slotted screw driver, sand paper, PVC primer and cement.
*If this is a new install please note a check valve will be required so chlorinated water does not back flow into heater / filter / pump.
*If this is your first time working with PVC pipe it is recommended that you watch some youtube videos on installation of pvc piping.
1 - Use the hacksaw to remove remove existing chlorinator or cut pvc to add the new chlorinator. Cut closest to the chlorinator to leave as much of the pvc piping as possible.
2 - attach the appropriate, included, coupling connections to the chlorinator ~ My application was 2" PVC
3 - Measure the length of the chlorinator and subtract the length in each side for the input existing pvc pipe.
4 - Mark the pvc pipe so the end result will be the length of the chlorinator, and cut pvc pipe to size as needed with hack saw. Use screw driver to de-burr the ends of the pvc pipes.
5 - remove coupling connectors
6 - use sand paper to rough the connecting point of the coupling connectors to be glued to the existing pvc piping.
7 - use sand paper to rough the existing pvc pipe to be glued to the coupling connector
8 - Use pvc primer to prime all roughed connection points
9 - Use pvc cement to glue coupling connectors to existing pvc pipe
10 - allow cement dry time as directed on bottle as system will be under pressure
11 - attach chlorinator to couplings and hand tighten. Take care to install the chlorinator with the proper flow direction.
12 - test system for leaks before adding chlorine tablets
13 - If there are no leaks add tablets and turn chlorinator value to desired position
