I bought a new anoroid that protects my water tank from corrosion. It is also the only way of draining the water tank when winterising.
When I installed it in the spring it seemed a bit tight as the plug was new I didn't think much about it.
Of course I used good judgement as far as tightening it and was careful not to overdo it as I would be draining in the fall again.
What happened is over the summer the plug seized on the tank and I thought I was going to strip out the threads as I had to use a lot of torx to removed it.
My question is what are people using to prevent this problem?
I know about anti-seize compounds but I am not fussy about petroleum products being in contact with the water system.
Anybody have any ideas?
