The drain to my washing machine has started to back up. I snaked out the vent, it did not seem to help. What could the problem be?

Hi Donna,

If you went on the roof and snaked the washer vent you didn't put out enough cable to reach the clog. Put out enough cable to reach the base and about 25 feet more toget to the main. Flush by cycling the washer. Good luck, Tom
