## Description

MavAquadoc Professional Seal A Leak

Review: Pull the filters, dump in the entire bottle and let it go 24 hours. Was losing 10+ gallons a day and it's completely stopped the leak and haven't lost a drop since. Is it a permanent solution? Probably not...but time will tell that tale (will update in due time) Update: Just shy of 3 weeks since treatment I have developed a small leak again. Treated with a second bottle and will continue to update the results. Also to note, you'll probably want to be sure to have a replacement set of filters on hand as shortly after reinstalling them they were plugged up. I will wait 48 hours this time before putting them back in.
Review: It actually does what it says it does, I had a leak that I just couldn’t find in my hot tub so I said I’ll try this thing, I had to do it twice but actually did the job effortlessly, I only used 1.5 ounces each time and I have a 5 person hot tub so I have loads left. But definitely something to have on hand if ever needed.

## Questions & Answers

**Q: how to add if no skimmer and dont know where leak is in my pond? do i turn off pump after the 8 hours once i add product to pond?**
A: Hi. The directions for Leak Sealer is as follows:

1.Turn pump off.
2.Remove cartridge or filter grids to avoid product from going past the filtration system.
3.If you have identified the leak, simply pour the recommended dosage directly into the water at the area of the leak. If the leak is unidentified, pour the recommended dosage to into the skimmer.
4.Wait 30 minutes after application, then turn pump on and run the pump for 8 hours.
5.After 8 hours, check spa to see if it is still leaking water. If it's still losing water, apply a second application within the next 24 hours.
6.Replace filter grids or cartridges after 24 hours and resume normal filtration.
7.Wait at least 24 hours before anyone enters the hot tub.

**Q: will this work on polypropylene shell spa leaks?**
A: I did not work, it was worthless

**Q: Would you need to run jets for 8 hours if only for a 75 gallon spa bathtub? Nervous to run that long.**
A: We recommend a full 8 hours to allow the sealing process to take effect.

**Q: How do you use with a sand filter**
A: This "solution" can be poured directly into the pool water, without the pump and filter system running. Let it sit for about an hour, then run your pump for an hour or 2. Let set again about an hour...now turn everything back on and you're ready to swim.

*by B***E on 17 November 2025*

Have a 600 gallon fiberglass hot tub. Leak was most likely in one or both return lines to the pump. Made several attempts to fix the leak with negative results. Leak was not changed. was hoping for it to work but no such luck. Cant say it is a waste of money for everyone as it apparently has worked for some. Not for me so i wasted my money
