Pool Leak Detection Dye Kit - with 2 Precision Applicators - 75+ Tests - Superior Long Lasting UV Pool Dye Easily Locates Leaks - for All Pool, Spa, & Hot Tub Types - 8 OZ (Fluorescent Yellow)

Great product, found the leak in my aboveground pool in minutes

Worked instantly. I was able to find the leak from my hot tub going back into my pool from a faulty check valve. I barely used any and will have alot more if I ever need it.

Worked pretty good

worked great!

Great product with a straight and curved applicator to allow access to all penetrations and access points. I easily located my leak and was able to repair. Highly recommend this product.

My video shows my first try using this fluorescent dye. My pool has a very slow leak from the spa into the pool. I'm convinced that the leak is through a grout line either below or between the single row of tiles that surround the top of the spa. The spa water drips through the stone wall separating it from the pool all night after the pump shuts off. The instructions on the dye bottle call for positioning the dispensing tip 1/2" from the suspected leak. Not knowing where the leak was, I held the tip maybe 6" above the water surface and dispensed a ribbon. The dye did not seem to disappear through a leak but I did see dye entering the pool below. I wasn't able to tell exactly where the leak was. This was obviously not the best way to dispense the dye. I'll try again by dispensing small quantities of dye near each vertical grout line, one at a time, until I can track down the leak. I have no doubt that I'll be able to locate my leak but it's small enough that it will take time. I like the ease with which I can see the dye in my pool and how it disperses slowly in calm water. As the description says, it does look fluorescent in daylight - like a yellow-green. The kit came with plenty of dye and two syringes with two different dispensing tips. I've been needing a syringe like this for years for precision dispensing of glue, but I couldn't find one. The bottom line: This is a nice leak detection kit at a good price.

Arrived in plastic bag with leaking bottle, making it messy to start with. Syringe is a little hard to control. When you really need a tiny ribbon you can get a cloud that covers too much area. Other than that, it does work. Really should be half the price.

Wow, that dye is bright. Easy to see. Just inject near suspected leaks and you can see it move towards the leak.

Work very well.

excellent yellow fluorescent colour, easy to see and stays visible long enough to identify leaks in pool liner and other areas.

Muy buena calidad
