Lo-Chlor Leak Sealer - 2 Pack

Closing my pool noticed small leaks and ordered this material. Leaks are sealed and have remained sealed for 2 weeks. Time will tell how well they remain sealed.

Had a leak detection service confirm that leak was in a return line. Purchased this product and followed instructions on the product label as recommended. Leak is 5/8" in 24 hours. Ran the pump on Bi-Pass for 12 hours (8 hours minimum recommended) then ran the pump on Filter for 24 hours. Checked water level and it had dropped, as usual, 5/8". Ran on Filter for additional 24 hours, checked water level and it had dropped another 5/8". I have 2 friends and a pool maintenance company advise me not to buy this product but foolishly did not heed their advice. Do yourself a favor, save yourself some money and avoid this product.

Super easy to use, and we stopped losing water the day we used it. Two problems I had: First, check the ingredients before you use it and then swim. I swam 2 days later, and I got hives almost immediately. So most likely silicone is one of the ingredients (or one of my other allergies). That’s no big deal for most people without silly allergies. :) Second, I think the leak is back after a month or so. So it’s a great temporary fix, and it’s possible that this water loss is more related to the Florida heat than the leak. But it was SO much less expensive than a real leak repair, so I gave it 4 stars. Overall, it’s good, not perfect.

I usually write a 1 or a 5 star review on things. This product is an exception. To get right to the point: This stuff may or not have made a small difference , but my leak persists.!! You are better off buying pool putty and applying it around where your skinner meets the pool. Almost half the price and worked better !

It didn't really seem like it helped at first so I put another dose in and the next day it was very hot the leak was much more obvious that it had slowed down by the end of the week the leak is no more in my fountain base on the side. I think it being in the upper 90's helped it set quicker the first day I added it was a little cooler. Definitely had my doubts considering I had already put a painted on masonry product that actually did very little and over a day ended up leaking more. I also bought that on Amazon. This stuff is like a liquid silicone I got it on my fingers and rubbed it together and it dried instantly and crumbled. So it gets into the nooks and eventually seals it up on account it's not some sort of big hole my problem was more of water seeping out of the fountain base. It did work which I was surprised actually for how little was used and the cost now I have plenty for other things in the future.

It did what it said it could do. I had a leak in my skimmer line that was very small. I put in a bottle but I let it stand for 24 hours after initial startup. No more air leak at pump basket. This saved me from digging a new line.

I am an old long time Cedar Hot tub builder and owner... leaks just happen with a tub sometimes. Typically I use another product every few years and I just pour the whole bottle in and wait. This liquid is pretty powerful... I ordered 2 large bottles to keep one on hand... but after only adding in a few ounces the leaks just stopped... WTH? It's been a week and I have drained and refilled and the tub still is not leaking... WOW what the heck. My concern is there is no mention of what this stuff is... I don't trust it to get into the water with it in so I drain and refill. For now I am absolutely blown away with how well this works. UPDATE went from 5 stars to 1 or zero. After 2 weeks I can say that all the leaks are now back. No idea how this worked so fast but it doesnt hold up.

This spring, I filled my pool knowing I'd need to backwash a lot upon opening. But, when I pulled the cover back, the water line was down 6-8". Since all returns and intakes were still plugged from the winter, I knew it was the bottom drain. (EEKS!) 33 yr. old built in pool, approx 8' to bottom drain. This is the 2nd time I've used this product. Both times it has worked. If not for this product I would have had to close the bottom drain, likely causing poor circulation and perhaps a dirty pool. I highly recommend it!!

J’avais une fuite importante dans mon SPA et le produit a réglé le problème, ça fonctionne vraiment, je suis très heureux.
