Question– “I am trying to unclog a tub drain. I removed a section of old cast iron piping, now the tub drain won’t drain at all, although there’s no blockage. If you wiggle the bathshoe the water tornadoes out. It seems like a level problem. Can you please help?”

Answer– In our opinion, it is your trip waste (this is the lever on the back of the tub that either keeps the water in the tub or lets it out). We recommend adjusting the trip lever.
