I ordered the exact PN PDM25 any yours will not screw in but pops in and twists? I need threads.

In the Pleatco catalog there is a adapter that has the 2 lugs on one end and a threaded end opposite. I was lucky that i did not throw out my old filter, so i used the adapter in the hottub on the new filter. Perhaps if you call the 800-886-5160 phone number they could find you one. I can email you some pictures of my adapter if you need them if you provide a address for me. Mine is for a dream maker hottub.

On mine I just kinda push it down and twist. No threads. It fits pretty tight. Mine is for a 2008 Dream maker odyssey.

this particular filter is designed to twist onto a tabbed adapter I was able to purchase an adapter from dayspring spas the manufacturer of our spa tub for this purpose at little expense otherwise there is a filter which is shorter in size that is threaded as well but I do not remember the part number.

Your old filter should have a removable insert with threads that you can take off and put on the new one

I noticed last night that mine is threaded upside down. I'm going to try and get a replacement.

It'l is supposed to screw in to the base. If it does not, yours is defective. I would exchange it.

I had no issues with mine. I did have to wiggle it a little to get the pin in but nothing major.

chances are there is not pins to order I try getting a new internal valve they don't sell parts, I learned my mistake do not buy oversea stuff and expect to find parts or get parts. for my setup I replaced the whole thing the valve was making grinding noise and as time went by it got worse and it was stuck off position....

Probably needs to be returned. I didn't have this problem. If can't return, I guess you could drill the heads off of the screws and use a vice grips to turn the threaded part out, then replace the screws with suitable hardware store replacements.

I am sorry I don't know the thread pattern. I thought it was a course thread?But don't remember for sure. I know once I traded knob on you place the plugIn aligned straight across. Sorry I don't know the thread side, guess 7/16??Lee

Mine go in but it is a Really TIGHT Fit. Seems like the negative spring is super tight, I pushed from the + end with a plastic knife.

Twist on. You need to line up the threads carefully, though. If you rush and force it, it will leak.

Mine has a plastic twist nut that screws onto the wand. If your plastic twist connection has the threads then it may be the same as mine and works. The wand brass end is threaded and attaches to a similarly threaded nut (mine is a plastic nut)

I had the same problem. The nut is an inset nut on the newer models (the manual diagram hasn't been updated to indicate as such); if you push up on the inset nut from the bottom while screwing in the bolt, it will engage the threads. Good luck!

Use a plastic screw (food grade and high temp suitable - e.g. for water lines) - that is the best option I can give you. The threads seems to be non-standard.You should also try getting the correct nuts from the seller.

Unfortunately it does sound like it is defective. The one I got has threads to screw onto any standard hose. I would request an RMA on yours.

I dound the right thread dog at Best Service Store. Volere PRB 3058. It came as a set of deive dog and prop and nut. Different size prop though. Not a real great fix. Hit me back if you dind a better dix

I've never had that problem. I thread locked the screws even though I thought it was overkill. Perhaps they were screwed in at a bad angle and finally gave out?

I had zero problems. May be a defective screw or it has been crossthreaded.

There's nothing defective about your unit check the second comment for contacts. I own several of these and the internal component isnt lined up correctly. Best of Luck. Stick with it. The reward is worth the trouble.
