re: Plumbing question??

If bleach doesn't fix it I call a plumber

BTW, is your house on a mechanical or septic?

Is this sink at the end of the plumbing line closest to the septic or mechanical?

Just asking because some people never pump out their systems then wonder why shite starts backing up into their house.

Of course it's more likely it's just a clogged pipe that a plumber with a snake can fix like I posted above.

if two gallons backed it up, it is a likely a clog in the wall behind the sink...maybe even the p-trap...
