Drainage issue from heating system and washing machine
Our heating system has a pipe for condensation removal (I assume) and runs through our basement to our laundry room, and shares the same pvc pipe that our washing machine drainage hose goes into as well. The pipe for the heater is a small clear flexible plastic pipe, and the drainage pipe is a basic black flexible pipe. The 2 are sharing the same pvc pipe, the heater pipe is being crimped due to the size of the drainage pipe, therefore causing a back up. How do we resolve this without replacing the pvc pipe? Can we use a wye attachment?
