Boiler stop leak

Pete_16

Does anybody know if "boiler stop leak" will seal a small leak in the piping just off the boiler?

stop leak ,will work if it is small pin hole ,if pipes are detoriated ,Iwould replace piping ,Their is no such thing as a quick fix that wont come back to cause you problems later. Iam not sure what it will do on impellers on a hot water system.

I have used many different brands of stop leak --its a crap-shoot some boilers have lasted for years others made it worse by cooling them off and putting stop-leak in some have held until the worst possible time then---well you know in between 50 service calls and other jobs going on we were installing a new boiler--T&M on overtime --if its piping more than likely its perforated if its a wet return, or if its at the threads the piping is so thin-----you need to replace it

Do it right

And FIX the leak. Stop leak is a bandaid that you're trying to put on wet skin.
