Pentair- Clean & Clear plus filter drain plug problem

Posted by luvh20 (My Page) on

I tried to drain my filter by opening the bottom drain plug. I tried turning, what I thought was the plug, and this cap like looking thing broke off exposing what is the plug.

The way my filter was installed, the plug facing the wall of my house, it is very hard to reach this plug.

I used channel lock pliers to grab a hold of the plastic
hex nut and was able to loosen plug and drain.

My question is, does anyone know if I can replace that
cheap plug with o-ring with some kind of plastic or metal
ball valve? Will I still need an o-ring if I use a male threaded ball valve with teflon tape?

It just seem's to me that there has to be an easier and better way than what Pentair has.

Any thoughts, suggestions, help from the experts would highly be appreciated.

I've got the same filter and when I was going through pool school the PB rep told me to remove that plug to drain the tank before removing the filters and I was like "You've got to be kidding me!! How the heck can I even get a wrench on that thing, and then get it back on without cross-threading the plastic threads on it??" Then I pointed out to him that there is a hose bibb installed on the plumbing that is well below the tank seam, and why can't I just open that bibb up to drain the water down low enough to remove the canister top and pull the filters? He looked at it thoughtfully and said that indeed he couldn't think of why that wouldn't work. And that's exactly what I've been doing, LOL! It works great. Hopefully you have a bibb like that on your setup as well, if you do then give that a try and leave the bottom plug alone. Don't forget to open the valve on top of the filter canister to let air in as it's draining down.

They make a tool specifically for that plug. The plug is best replaced with the original. A pro can remove it pretty easy as we do it hundreds of times. That's probably why your guy said to remove it like it was a no brainer. The wrench is easier though.

trsew- I do have a hose bib attached to the line going from pump to filter, I'll give that a try. Thanks!

repair guy- where does one get that tool for the plug?

Thanks for the info.


RE: Pentair- Clean & Clear plus filter drain plug problem

I'd imagine you can get one anywhere. e-mail me and I'll find the part number by then. I know they are about $45.00

RE: Pentair- Clean & Clear plus filter drain plug problem

repair guy - thanks, but for $45.00, I'd rather drain it another way, and use the $45.00 to get a half a tank of gas.:)

RE: Pentair- Clean & Clear plus filter drain plug problem

Channel locks work great but when one can't get that to work, the wrench is the solution if you want no headaches. I use it all of the time but then again, I use it 15-20 times a week.

RE: Pentair- Clean & Clear plus filter drain plug problem

Well I guess I was a little confused.
The plug itself had a plastic cover over it that is glued on. The first time I cleaned the filter, I turned the cover, and the plug came out, and I reinstalled it.

The next time I went to remove the plug, the cover broke off. Why that cover was over the plug is a mystery. It had a small hex nut on it for a wrench, but the cover is only glued on to the plug.

Pentair sent a warranty person out today and he installed a
new plug, but even he didn't know why that glued on cover
was on there.
He did give me a tip on removing the plug, use the shaft of a screwdriver that will fit in the slot of the plug and turn it. I'll try it next time.
I do have this to say about Pentair to anybody who is
trying to decide between equipment. I called about my plug
filter problem one day, and they were out the next day to fix it. Now that is service!!!


RE: Pentair- Clean & Clear plus filter drain plug problem

That slotted hex plastic plug does loosen easy with a screwdriver blade but it is sometimes a bit tough on the Pentair. The same plug is on the Hayward and the access is easier. The newer versions of the Pentair tank have a totally different plug that can be turned by hand.

The only drawback to this filter is that every piece of black fitting that engages the tank is weak. From the bulkheads, to the plug to the air relief. They crack, leak and loosen more than any other brand out there. The only saving grace is that the tank itself is probably the strongest compared to the others. You'll replace more tank lids and bottoms on Hayward.
