Pool Leak Detection Kit – 8 oz Blue Dye with Reusable Syringe – High-Visibility Leak Finder for Pools, Hot Tubs & Spas – 40+ Refills– Professional Water Tracing Tool

If you are reading this just buy this stuff! I knew I had a structure leak, but had zero faith this stuff would help me find it so I did the dumb thing and guessed by using epoxy all in my skimmer opening and even grouted a few spots I thought could be the source of the leak once the water level stopped dropping. Everything I did was a waste of time and $. I bought this as a last resort and in no time I found a pin hole leak in the title grout on my top step! Without this I never would have seen the hole or guessed the leak was even in that spot! Use this to check all your spots that have grout.

Came on time and worked as expected.It took more to find the leak so I’m happy that I just didn’t buy the syringe full. I bought the Syringe and bottle.Thanks

Wasn’t sure when using it, but found the leak because I puttied where I thought it was leaking and where the fluid appeared to be going & sure enough, no more water loss.

Works good

My pool had a leak and I tried some food dye and thought I had a idea of where the problem was, But since my inground pool is surround by concrete I need to be sure. So I ordered this.It really did not work much better then the food dye, but there was much more so I did not feel like I was wasting my fluid. I came to a similar decision that it was one of the pool return jets, but since they are all connected I did not know which one. It was able to rule out the drain, skimmer and auto filler. In the end I hired a guy with a special microphone device that he could hear the leak and zero on how far into the return line pipe it was cracked. (turned out to be less than 1" from my fiberglass pool.So if you want to improve your guess, this stuff is OK, but if you want the real answer, get a pro with a listening deviceMy leak detection and the expert were in sync, the expect told me exactly where issue was and the dye had just told me somewhere in the return lines

This dye did not work quite as well as another dye did. The syringe definitely comes in handy for pinpoint an area that you want to check for a leak. But I think the gallon green dye worked better. You can definitely see it in the water is more of a neon where this wasn’t really bright, but it works.

Syringe Came Broken

Worked well
