## Overview

Lo-Chlor Leak Sealer is a liquid solution designed to effectively seal minor leaks in pools and spas, preventing significant water loss and potential damage. It works within 24 hours and eliminates the need to empty your pool or spa, making it a convenient choice for pool owners.

## Description

Seals minor leaks in most in-ground swimming pools & spas. Can seal leaks losing up to 1" of water per day in a 15,000 gallon pool. No need to empty pool or spa. Fast acting - usually stops leaks in 24 hours. Lo-Chlor Leak Sealer is an amazing special compound that has been developed to help seal minor cracks and leaks in swimming pools. A leaking pool is every pool owner's nightmare. Lo-Chlor has developed an easy way to plug minor leaks. Leak Sealer has a very high pH (about 12) so when you add it to your pool it takes on the pH of pool water (between 7.0 and 8.0). It now no longer functions as a liquid and starts to solidify in the presence of oxygen at the site of the leak. To ensure best results, please follow the instructions from the manufacturer.

## Customer Reviews

### ⭐⭐⭐⭐⭐ It did work takes a little wait time.
*by A***� on May 30, 2024*

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.

### ⭐ Doesn't work
*by J***K on August 29, 2021*

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.

### ⭐⭐⭐⭐ Definitely worked, but I think the leak is back
*by 2***M on May 28, 2024*

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.
