Anderson Refill Florescent DYE for Pool and SPA, 8 FL.OZ, Fluorescent-Yellow

Did what it’s supposed to do

Very very bright glow with blacklight flashlight! Helped me find th leak in my rv pipes immediately! I hardly used a teaspoon amount and hv a practically new bottle tht will tk me forevet to use so id say worth th money in th long run especially if u mess with plumbing at any point. Id highly suggest it as a gift for the plumber in ur life theyll love it if they dont hv it already!

A good product. Would have been better if I knew how to use it. My leak detection efforts with the dye showed no leak, but we continued to lose water. Called in the pros who, by the way, use the same dye and he found the leak. Instead of simply squirting the dye near the drain or plug or wherever you'r testing, one has to "Draw the dye out very slowly like drawing with a pencil." Yup, he found the leak.

AAAA

It worked and was highly visible. I used a regular medical syringe to inject. As our botique hotel is in Mexico, PlayaLindaHotel.com we have issues transhipping from a US address so look for alternatives. You might first try a mix of Chlorine powder and Chlorine checking agent to make a bright yellow dye. also I would suggest 1st to check your pool filter valve is not leaking to the drain when the pump is running, perhaps if you have a connection you can loosen on the drain line to check, alternatively leave the pump off for a day and compare pool drop to regular evaporation rate. i look after a 20 year old Jacuzzi and a 8 year old Hayward sand filter and both leak to the drain. I have a shutoff valve plumbed in to drain after each now that I independently close, of course one must make sure to open it before doing a back flush, or anything that sends water to the drain. Regards checking for a leak it was bad dropping several inches in a day so I let the pool drain until it stopped, then added a inch of water. I injected a thin line of dye around the pool close to the edge and very quickly found a spot between some tiles where the dye disappeared between some tiles. I had some stuff you are supposed to be able to add to a pool to seal but it just sucked through as well so I used some epoxy putty which did the trick.

Works perfectly. I had no idea where the leak was in my pool so I did the bucket test to figure out if the leak was in the tile or pipes. Once I knew it was in the tile I took this around the tile in my pool and found the leak within an hour. Definitely worth not spending $100+ on a professional detecting the leak. Very nice product

Excellent product. Found leak in above ground pool in less than an hour. Saved on huge repair service call.

The fluorescent dye held together very well and was very visible in the pool water. While I didn't locate any leaks during my 1st attempt ( trying to locate a very small leak even professionals have been unable to find), I do feel if this product could be used to find bigger leaks.
