    Any suggestions on how to patch a hole in the bottom of a steel boiler feed tank? 100 gal. tank, 25 years old, the new one is on order, but will take 4 to 6 weeks. I might need the boilers before that. The hole is about 1" in dia. There is 0 psi. Weld, chauk, epoxy???

    welding gets my vote

    epoxy patch would be my second choice on a VENTED boiler feed tank repair.

    cast or steel

    is this the maint feed tank or a condensate receiver /pump package. you can weld the steel easily enough, cast on the other hand requires nickel rod and should only be done buy a pro

    I'd use marine epoxy..it's a 2 part like most but alot stronger I think up to 2000 psi (but i don't remember)

    If you have a one inch hole in the tank now, most likely the metal around the hole will be thin also. Welding may cause more problems from burn thru. I would use an epoxy patch and if you could wrap a couple of steel bands around the tank to hold the patch in place it would help.

    They make , oh crap,
    its a bolt with large steel washer /rubber washers. Tighten it up and your good to go for a few weeks.
    I did the bottom of a condensate tank(approx 1"hole)
    this way untill new tank arrived.

    I think Dice use to call it a rubber bolt thingy

    You could make one!

    I'd get a big ole' fender washer and hammer it on a handy six inch pipe to form it.

    Then get a 1/4 20 Molly bolt and put the fender washer (that's a big washer with a small hole)on it.

    Then get some silicone high temp sealer and smear it on the mating surface and then tighten it almost all the way down.
    Let it cure for awhile, then torque it down further.

    Like it has been said- this is only good for a temp. repair on a 0 psi vented condensate reciever.


    And Good Luck.
