Catch Basin/Grease Trap Lid repair

Posted by Ken on May 30, 2008, 2:12 pm

Hello,

I have an in-floor grease trap lid that needs repair. The bolt holes are
stripped and one eyelet hole for the lid has broken off. Please recommend
any "Do it yourself" resources for me to use to re-tap the the bolt holes
and "weld" the eyelet back on the lid.(Lid is cast iron. House was built in
1940's. Or, if anyone can suggest an alternate means of securing the lid I
would greatly appreciate it.

Thanks Ken

If it really can be reapired you would need some welding equipment minimum
and a sand blaster would be nice to clean it up. You should check the
yellow pages for a blacksmith ing, they are getting rare but would be
exactly what you need. If you aren't already experienced in welding, then
it probably isn't a job for you. While you're at ti, check the Y pages for
Welder as well.

I guess the alternative would be to dig up and replace the old trap with a
new one at great effort.

Brazing would probably be a better option, both to reattach the broken
cast piece, as well as to fill the stripped holes for redrilling and
retapping. Potentially DIYable with one of the little Oxy-Mapp setups,
though Oxy-Acetylene would be better.

As another option, a filled epoxy like JB-Weld would probably be
adequate for filling the stripped holes since there isn't much load on
those bolts. JB-Weld is DIY, and you could take the cover to a local
welding shop for them to reattach the broken piece. Would save an
on-site welding / brazing trip and associated cost if you're not up to
doing the work yourself.

Ken,

Google "heli-coils". These are sold at auto parts stores and are used to
fix stripped bolt holes. I've no idea about the eyelet without seeing it but
wonder if an epoxy will do the trick.
