So....I cam home the other day to my hot water leaking water all over the basement floor. I took off the supply hoses and found that the cold water inlet nipple was badly deteriorated around the threads and was no longer able to make a seal with the gasket in the supply hose.
I decided at 7pm to start some emergency plumbing work, since I value hot showers in the morning. I went to the big box (orange one) and they only had 3" dielectric nipples, so in a pinch, I decided I would use 6" galvanized steel nipples until I can get my hands on the proper 5" dielectric nipples.
So far so good.....that is until I put a pipe wrench to the 15+ yr old water heaters nipples. Even with my largest wrench and almost tipping the water heater over from torque, nothing was budging. The nipple itself started to deform and collapse on me.
This is a common occurrence when I'm working on cars suspensions here in the N.East due to all the salt. Everything is rust-welded stuck. So the mechanic in me said, oh, this is no problem. Let me do what I always do --> PB Blaster and torch. I sprayed the nipples with PB Blaster and hit it with the MAPP torch for about 30-60 seconds each. Then they came loose like butter. No issues there.
Installed the new temporary nipples. Hooked up the hoses. Leak tested. Everything great! Job well done....but wait...
My hot water has smelled so strongly of PB blaster for days, it's unbelievable. That stuff is some kind of unholy concoction. I thought to myself, 2 or 3 sprays a nipple and after a hot shower or two, the stuff will be gone. Wrong....
It doesn't seem to be fading even in the least. I assume its floating like a slick on top of the water in the heater, but I had thought the first few gallons of flower through it would take it all with it right off the top. It didn't happen the way I thought.
Any thoughts on how to get rid of this unholy hellish stuff out of my water heater? Now every time I run the dishwasher, do the laundry, take a shower, I'm infusing everything with some small amount of PB blaster. Enough that I can still smell it very strongly.
Do I think it will kill me? No. Am I happy about the way it turned out? Not really.
Any tips, tricks, or suggestions? My only thought it to open up the hot water outlet hose and put a few drops of Dawn liquid dishwashing soap in. My hope is that the soap will help to break up and emulsify the PB blaster penetrating oil slick on top and disperse it, such that it actually flushes as I use hot water over the next few days.
