Too Tight Unions
The 3" PVC unions before and after my external pump were tightened by someone not available to help now. They are too tight for me to loosen by hand or with a strap wrench.
Does anyone have a tip or know how to loosen the unions? Is there another tool that would help? I would like to remove my pump for the winter although I can drain it in place and leave it--worst case scenario.
Since heat expands, I'm thinking a hair dryer or pouring very warm water on them might help, but I don't know the tolerance of PVC or ABS for that.
I hope to get it done in a warm stretch we are having. Thanks for any ideas.
