My washmachine drain will back up during the spin. some times it is ok. I have tried draino and a snake but I still get back upthe drain is 1-1/2″ and I have a new washmachine (Kenmore). we just moved in to this home so we do not know if this is a old problem. please help. all wet!
First thing 1-1/2″ is to small of a pipe. You need 2″ or 3″ drain, also your soap might suds up too much. Have a Plbg. come in and change the pipe size . Let me know.
