lime deposits

ddenny

someone has an old boiler and wants to sell his house. doesn't want to buy a new  boiler . but there are lime deposits and rust around the copper fittings going in and out of the tankless coil. any sugestions on how to dress it up and maybe scrape the buildup off or would I be risking a leak. any kind of rust inhibitor I can brush on? It's a ford. I never replaced a tankless coil but this one doesn't look as difficult as others to remove but you never know.                   thank you.

removing lime deposits

on our previous boiler, the steam piping had been incorrectly piped with 4" copper. the solder joints always had a few leak areas with lime deposit build-up. before the annual boiler inspection, i would put a copper wire brush in my drill, and remove the crusty bits. that kept us passing the exam, until the inspector discovered a leak in one the sections..but that's another story.

if you are an installer, there might be some liability if you were to make only a "cosmetic" repair like that.--nbc
