I am having a problem with a P-trap under my bath tub. every 6 to 8 months, the p-trap works itself loose and leaks. I then have to open the ceiling up, re-tighten the PVC trap, re-patch the ceiling and re-paint. Does anyone have a solution to this problem? Is there something like loc-tite for PVC? Help!!!

To prevent moisture buildup and improve performance, install a continuous air barrier—such as drywall or specialized membranes—under tongue-and-groove boards or other interior wall paneling.

You could drill a small hole through the side of the nut and wire it to something stationary (ala aircraft safety wiring).
Thats actually not a bad idea. I will look at the nut to see if theres enough lip to do it with. Its pretty funny though. I had an old jeep along time ago and had to do the same thing with a loose steering column. I used aircraft wire to keep it tight. Thanks, Jon
Put in a glued together P trap. For a non accessable area it may be code to have a glued together trap (You would have to check your local codes)
If the P-trap is working loose, it's because something's moving. It may be the pipes in the wall moving up and down, it may be an adjacent toilet rocking, or it may be the tub itself bouncing due to poor support. Figure out what it is and see if you can correct the problem.
If I couldn't figure out a permanent fix, I would at least put a tastefully trimmed access hatch in the ceiling.
I was thinking that's probably a good way to guarantee it'll never leak again.

if you have slip fittings by code you have to have an access hole.why not just get ABS fittings and glue them up. there is a glue that can be used to glue ABS to PVC if necessary.
Could I not just use PVC cement on the slip fitting just as well? I like the idea of the hockey tape too.
The cement would likely set up before you had the two trap parts tightened all the way.
Dunno about the PVC fittings- we don't use that stuff around here except for drainage. But on the ABS fittings, the nuts are polyethylene- glue won't touch them.
I'd figure out what's vibrating this thing loose and fix that- urgently. If it's not the trap, it'll be something else that fails later, probably somewhere much less easy to fix than your trap.
Wrap two layers of hockey tape around the joint and for a couple of inches above and below it. The nut will not turn until you take the tape back off again.
But do as Dan suggested first and figure out why it's working loose. It's not supposed to do that.

As someone posted if you have "SJ" fittings (slip joint) they must be accessible.
Most pvc glue will glue abs to pvc, although that is not legal, must have a "transition" coupling.
Gluing your current "p" trap as someone posted will probably set before completely together then yer screwed.

Dan h is right you have to remove tub then set in wet cement to stabilize it
Well, I didn't say that. If the tub is moving probably some bracing can be installed from below to stabilize it.

How can you brace a tub from below? theres a floor there
Yeah, and he's opened up the ceiling, and can see some of the tub bottom through the opening for the drain.First off, a very likely scenario is that a joist was cut to install the plumbing, and fixing that problem somehow would rectify the situation. Next, if the problem is floor bounce, sistering the joists or installing bridging would likely help. Finally, if the problem is that the tub bottom itself is moving up and down, bracing it through the (possibly enlarged) drain opening would prevent movement of the trap.

Agree with BigBill, use a glue trap. Do not mix ABS+PVC together. Universal glues have been banned where I work, [The N.E.] for many years; they will leak. If you use a glue trap the only nut you will have will be accessable on the back side of the tub, not the ceiling. You should have a access panel there anyway. Lots of luck.

" Universal glues have been banned where I work, [The N.E.] for many years; they will leak. "That is the wrong type of glue.Universal will work on either ABS or PVC, but it is not designed for use on a combination.However, there is a TRANSISTION adhesive that is speced for that purpose. But IIRC you are only suppose to have one per house.Of coure there are the rubber (fernco, mission) type of couplings that can be used.
Sorry Bill, I guess that I wasn't clear on my post, what I was trying to say is you can't mix the material with universal glue. My bad.
