How to remove and clean UV sleeve?

TWYOUNG · Sep 30, 2022

It's time for me to clean my Pentair 40W UV Quartz sleeve for the FIRST TIME and I'm a little anxious about it. Do I need to drain it? Do I just unscrew the smaller grey part or do I need to disconnect it at the larger black cap? Are there any videos showing how to do this? The only ones I've seen are for large commercial models. Thank you so much!

Shut off flow to UV first, remove black cap, lift out bulb, then you should be able to lift out the quartz sleeve, they can be stubborn to get out.

So no need to drain it? Will any water come out? Just to clarify I'm not replacing the bulb so I imagine the bulb will just remain inside the sleeve while I clean the sleeve?

I don't know, depends on your UV plumbing. Got a better picture of the setup?

With it mounted vertically like you have it, you shouldn't need to drain it. I have the same model mounted the same way. If you still have the instructions that came with it, there are detailed directions in there on how to remove the different pieces.

The UV is on it's own pump which I will shut off. I installed a valve after the UV which I can close to eliminate any backflow.

Then it should be fine with no drainage issues.

Thanks for all your help. Shouldn't have been so concerned as it couldn't have been easier. As it turns out after 3 months of running it looked to be totally clean and not in need of maintenance. Cleaned with vinegar anyway a replaced.

I would remove it and give it a good cleaning while your cleaning the sleeve. Mine gets a lot of crap in it.

Clean what in addition to the sleeve?

The whole unit. Mine is an aqua but I remove it and flush the tubing out with a hose. also I clean the pump at the same time. Where the sleeve goes that tube gets Detritus inside.
