I didn't want to post this in the same thread as above, so, There is a hardware store that is across the street from our shop ( at work) They have been around for a long time. You used to be able to find things there that no one else had. A true country hardware store. Well the old people that owned it, and worked there, just got to old to run it any more. They sold out to true value. True value is messing up the store, It is nothing like it use to be. The specialty items that they used to have are all gone. I walked into the store the other day to get some PVC glue for my TIG torch, cooling pipe. I have a PVC manifold to run 3 different TIG torches, and a cooling pipe we use. I sprung a leak in a PVC elbow, so I pick up some blue PVC lava glue. I ask one of the 2 clerks there if this was for hot water. He said well um I thing, I stopped him rite there and said, hey thats ok, if you don't know the answer, you do know. I will take this, because I am almost sure this is what I need. I get back to the shop. I show the glue to our shop helper, and he said, yea, that is what you need. Its for hot water. Its a shame when a 21 year old kid, knows more than a 45 year old man who works at a hardware store.
