Need Help to Drain Pentair TRII 60

[Petra Pool]

I have a new Pentair TRII 60 sand filter with side Mount. This is the first time it is being winterized. I noticed after the pool service person drained the pipes that there is still some water in the sight glass on the multi port valve. The response I got back from the pool winterizing service person was that the sight glass was too tight and he didn’t want to break it, so he didn’t remove it. Does the sight glass typically get removed on this model TR 60 for winter?

I agree with him on the sight glass being very tight and perhaps not good idea to try to force to remove it as it might break.

In addition, it appears that there is a drain plug on the bottom of the filter that was still left in.
My pool service person claims he removed the plug and I am seeing the female end of the drain assembly and the drain plug feeds into that assembly.

The parts I see removed do not look fully like all the parts to the drain plug however. There is only one white type screw. Please see photos below. It appears the twist tie drain plug part is still attached to the filter or was screwed back on. The black twist plug removed and in the white skimmer basket photo below is the aspiration part on top of the filter.

Please advise on how I could further drain the water from this filter to get it out of sight glass and elsewhere to be safe. Is it possible to drain with a shop vac somehow? Should I be worried that my filter was not fully drained properly? Thanks for any help on this.

The photo with the drain plug is a bit dark and hard to see, but it appears to be the female spigot portion still installed. In your strainer basket it looks like the small black drain plug that screws on to it. I also see what appears to be the black bleeder valve T fitting.

As for the sight glass, you might try a small strap wrench.

Hi Texas Splash! Thank you so much for your help! I took a closer look at the drain plug area and you were right it looks like the black plug was from the drain hole and Actually was removed. It appears water is still draining out very slowly from the sand filter. The other black part In the skimmer basket was the T part with the pressure gauge and the aspirator as you already assumed.

I don’t know what the white plastic type screw is though that was also removed. Is this part of the drain plug area too? If not, Where does this part go?

The Pentair manual doesn’t say anything about removing the sight glass for winter and I am concerned this is pressurized area too so maybe not a good idea to try to remove it. Is there any other way to try to get remaining water out of multiport valve area and sight glass without removing the sight glass?

Here are better photos of drain area attached. Thanks again!

I don't have a Triton TR-series filter but I see no reason to remove the sight glass. It will not be pressurized (and will drain) when the pump is off.

The filter drain is a two part drain assembly.

This part is like a small lateral and it allows the water to drain out without allowing sand to come out.

The plug part screws into the hole you can see.

Some people accidentally remove the whole assembly and sand comes out.

In my opinion, it looks like the whole part was removed by someone because they did not know any better and then they screwed it back in when they realized that they made a mistake.

It is actually very difficult to reinstall this part because sand will keep flowing out and that jams the threads.

You can tell they removed the whole part because there is filter sand on the ground.

I suspect that it will probably leak when the filter is restarted in the spring because it looks cross threaded and it is basically impossible to seal with the sand in the threads.

What are the 4 stainless steel screws from?

Can you show the whole system?

Here, you can see that the plug is slightly off from where it should be.

The threads should be the same distance, but they are off by about 2 degrees, which indicates a crossthread.

To me, it looks tilted about 2 to 3 degrees from where it should be.

The part also looks like it has a tool mark like a pair of pliers was used to unscrew the part.
