This week on the Handy Ma'am Hotline, Mercury helps callers with a sink drain that just won't stop stinking up the place, a toilet not flushing and figuring out what can be done for a non-vented toilet, dogs peeing all over a metal frame to a screened in porch, a 120 year old house whose pipes aren't underground and freeze during the winter, and testing for lead paint when removing old trim in another 100 year old house.
