Thanks - I ordered a couple of these to give them a try. I'll have to drill a hole for the ground wire as well (can't find any for 3/4" pipe w/ 2 holes ready to go). If it still leaks, I can drain to below these and add sealant around the plug. I should probably drain anyway to get the water...

After a lot of pressure testing, dye testing, etc., I found that I've got water flowing into the electrical conduit in the back of one of my light niche's (wet niche, Pentair Intellibright LED light fixture). There is a bonding (ground) wire and the light cable running into the conduit from the...

Does anyone know how much chlorine is released from a hot tub as chlorine gas? Obviously, there are a number of variables here so we'll assume perfect water chemistry and FC level. Obviously, chlorine gas is 'suboptimal' for inhalation and I've always assumed (maybe incorrectly) that the level...

I've been reading up on the chemistry of the different chlorine compositions to determine what to use when I can't get liquid sodium hypochlorite (thanks ChemGeek) and ran across something odd: The link below is to a granular trichlor product - which sounds like the stuff people are using in...

Thanks for the responses. I did disabled the UV on the hot tub because it did not seem to do anything for my water and since it kills the chlorine, I think it's actually a nuisance. I also have a large UV sanitizer on my salt water pool. Hmmm... interesting idea to nuke that as well but it's...

From what I've gathered on this site, it seems the chlorine should only be decreased by sunlight and attacking organic materials in the water. So, if I have clean water and no sunlight, should my chlorine levels be stable (such that I should not have to add chlorine)? This question is...
