Our main line was plugged up with tree roots so we went and rented a sewer auger and ran it down 3or4 times every thing was flowing great until my wife took her bath when she started to drain the bath tub so did the toilet until there was hardly any water left in it.our venting system has something to be desired the vent is in middle of all the fixtures and its only 1/12 or 2 inches in the bathroom. no vent for kitchen sink. Dishwasher . or washing machine.could this be a venting problem or did we not get the main line clean enough?
