Tips on opening old canister typer drain trap
Posted by Doug Rosenbaum on December 24, 2003 at 08:29:12:

Drain from the washer is clogged- probably too much dog hair and lint. The trap is a vertical canister - looks like cast iron- with a clean out on top with the 1.5 inch square. My house is from 1921, and for all I know it hasn't been touched since then. I tried liquid wrench and a 14 inch pipe wrench, but can't budge the thing. Does anyone have any tips before I get a 3' pipe section to help the wrench out? Would heat help? Thanks.
