Frankenplug Swimming Pool Leak Repair (4" Pool Fitting)

It worked like a charm! Had a huge split on my return jet fitting. Ordered the 4” franken plug and it stopped the leak 100%.The plastic and piece was just a tad too big for my return line and it did not fit. I took a file to the end piece as it doesn’t assist in stopping the water. After filing it down a bit, it slid right in, and stopped the leak instantly.If it doesn’t fit for you, take the 3 minutes to think about it and how you can resolve it without just giving up and returning the product. The plastic piece on the end DOES NOT do anything to stop the water. The rubber is what does that.

This little guy fixed a leak.We ended up having the fitting replaced as it was covered under warranty, but now we have a big hole in the concrete pool deck.The plug was so easy and now I almost wish we just left it in place instead of replacing the fittings.

If you are selling your home or just want to put off repairing your pool this product works. I have a small leak where the fitting glues to the pipe on my return jet. Installation is easy and it sealed for 6 months. This is a bandaid fix and not a permanent repair.

It didn't quite work out for me. The inlet diameter was too small and it was adding 10 psi to my system. It went from about 12 to 22 psi. I didn't want to risk ruining my system as it's already fragile. Outside of the psi increase, I think it's a great product, I would've kept it on if it didn't put too much pressure. I know it's still within working condition but I just didn't want to risk it. Instead, I'm going to try the drain Frankenplug next. That one has a 1 inch diameter instead of this one which measure 5/8 inch.

When we uncovered the pool this year, the water level was lower than normal. I followed the 'dirt' line ring on the pool and it appeared to lean toward an issue with the pool returns. Using some food dye, I discovered a crack on a inground pool return built into the plastic walk-in steps. The crack was where the threads begin where the eyeball would screw into. The only way to change this would be to cut the concreate, dig and replace which will be an expensive job. I took a gamble with Frankenplug and it appears to be working perfectly. The pool was dropping about 1.5 inches everyday and this plug stopped the water loss so far.It's hard to determine how 'tight' it needs to be, because at the same time I don't want to crack it worse than it is. At first installation, my dye tests were good, except I felt it still was losing water. I tightened it a bit more, and now it seems to have stopped. It's a great concept for sure! Tightening it pulls the front & rear of the plug together causing the rubber middle to expand, (like squishing the rubber)-- Good luck!

it does not fit

We had a leak in one or both of our pool returns by our steps. As a last ditch effort to save substantial time, effort and money in breaking up concrete to replace pipes, we gave this a try. One of our returns was badly cracked and was losing 2 to 3 inches of water overnight. After using franken plugs we are losing less than 1/8th of an inch overnight. We did have to alter the plug slightly due to pipe becoming more narrow than the end of the franken plug. Hubby used our grinder to carefully shave down until pipe fit perfectly. A great invention that I am hoping will last for years

Various opinions whether this is a 'permanent' fix or a temporary fix, but, I'll take an $80 gamble over a $3000 repair bill any day. 2 suggestions, though: (1) it'd be nice to be able to aim the inlet, like the original one (that wouldn't be real hard to do) and (2) provide a plug to seal it for winterizing (also not real hard to do). I'll give this a 5 rating anyway just for the amount of money it has saved me (so far). If the manufacturer reads these reviews, it'd be nice to have the suggestions taken seriously.
