We are doing laundry and all of a sudden the hose in both bathroom toilets is bubbling and that includes the hip bath and shower, What is happening? We not long had the washer fixed did something bring hooked up wrong, or do we need to repipe? Thank you.
Answers:    The drain column is blocked enough that the spend in dribs and drabs water from the washer is going out but not down the drain. The blockage could be anywhere contained by the line, but probably downstream of the ending fixture in the system i.e. bubbling. A power snake is best solution, rent one if you can handle it, save call a roto rooter type service man. The adjectives causes are tree roots, sludge, or a broken row, or a low spot in the chain. About 2 hours with a power snake will usually verbs it enough to drain. Long occupancy solution is to properly repair it.
1you either enjoy a major clog 2 when they put the washer surrounded by the drain the vent is not getting air or it's getting to much nouns sounds like a mission for roter rooter / plumber
