Adventures in Plumbing
The original installation (2009) came with steel, i.e. magnetic, tank bolts.
Eight years of anaerobic, carbonate-rich water dissolved the heads of the bolts.
The rubber washers had no compression around a portion of their perimeter.
Viola! A water leak.
The replacement bolts are non-magnetic and look like brass. I expect them to last decades.
The bottom of the tank has a hairline crack in it but I think we have enough dissolved minerals in our water that it will seal up as long as we don't put things in the tank to minimize rust stains.
