Hello to all,

Hope everyone and their families are all safe and doing well.

Need to perform a leak test at the 2 drains and light of my spa. Cannot get the dye to these levels w any concentration to discern if I have water movement or not? I have 8 jets/returns and was able to see that no dye rushed out of these areas...

thank you very much,
tstex

tex,

I have used this... Pool Leak Fluorescent Dye Test with Syringe - ANDFT601

Plus bottles of refill.

That said, I was never impressed with the performance of the dye tests in general. Any water movement makes the dye almost useless.. I believe that it only works when you have a massive leak.. A little leak just does not suck the dye in, unless you are right on top of it.

Thanks,

Jim R.

Thanks Jim / That's certainly a better approach.

I read the entire link and didn;t see anything on how to get the liquid to a place 2-2.5ft below water line...is the product viscous enough that it will not move from my water movement? Thoughts? thanks again

No, it is thin as water... Water movement from trying to get to the problem is part of the reason that I was not all that impressed.

You are supposed to take the whole syringe underwater. Bring the end close to where you think the leak is and then squeeze the syringe to release the dye right next to the potential leak.

Brett,

I think we understand that, the problem is that just getting the syringe into position cause the water to swirl and move.. Even if you try to stay still, it is pretty hard to keep the water from moving.

Brett, I get that. But if my spa drains are 2.5ft under water and I stick my arms in and discharge as you say, Jim is saying the movement of my arms in or back creates enough water movement that it moves the dye away from the target area.

Based on the size & design, I think these were geared for skimmers, or cracks around the water line where the 6" extension can easily access and you don't disturb the water. If there's something I'm missing, I'm all ears bc I'd like s soln. Thanks
