Hi everyone,

I’m looking for advice on a pool installation issue. While we don't build pools, we construct custom homes, and one of our clients is having trouble with a pool that was installed by a contractor we recommended and hired. The pool company is refusing to fix the problem, and after testing with Canadian Leak Detection (who were great), we've determined the leak is coming from both of our Aqua Lamps.

It seems the pool installer may have overtightened the lamps, which caused several screws to break free. We’ve tried removing the AL7, caulking behind the ring, and installing new gaskets. We also caulked where the AL7 meets the AL10 inside the lamp because a dye test showed a pinhole leak at the 6 o'clock position on both lights.

After further inspection, we found that the AL6 screws are spinning and the brass inserts in the AL10 have pulled out slightly, now sitting about 1/16" to 1/8" proud of the AL10. Since there's 10 feet of concrete decking above the lights, we can't replace the AL10 without cutting into the concrete.

Does anyone have a solution for fixing these brass inserts so they sit flush with the AL10 and stop spinning? We want to ensure good compression of the AL7 against the liner when we install new gaskets and tighten the AL6 screws into the AL10 brass inserts. We tried epoxying one of the screws but did not have good sucess. MAybe we used the wrong epoxy??

Thanks in advance for any suggestions!

Would a Rivnut work? Amazon sells a kit with different sizes and the installation tool. I’ve used them for various things around the house and they work great.
You may need to countersink them in AL10

Appreciate the idea. Took a look and it could work. I'm a little nervous that it might crack the plastic on the AL10. If we don't have any other suggestions it might be worth a shot. Thanks for the advice!
 
Hmmm, this may be a long shot as well but a self tapping threaded brass insert might get the job done if you can extract the original insert. Something like this. You might consider locking it in with a little epoxy.
 
How about using JB Weld to stop the brass inserts from spinning. JB Weld is strong as heck and waterproof when dry.

Push some JBWeld under the loose part with a toothpick, then build up a bead on the backside of the insert and glue it to AL10.
