Hello:Â Not to be contrary, but I never put anything on a frozen pipe I wouldn’t mind having in my water.Â So, I must disagree with the advice you got.Â Brute force is better for you than penetrating oilÂ 😛
I agree with your statement and thank you for bringing that up. However this is the only solution I have at this point. Brute force just didn’t prevail unfortunately. Minimal amount of the PB Blaster, none went down current nipples. While some may penetrate through the threads and into the tank. I imagine by the time we would consume the hot water(if ever) most would be dilluted enough to be harmless.
