: I recently connected the drain hose from our washing : machine under our laundry soak sink via a T-connection : so it no longer simply rests in the sink. Unfortunately, : the washing machine will no longer hold water. Instead : it runs directly out the hose/sewer line even though : I have the hose running up to nearly the same height : it would have when it was lying in the sink. Is it : possible to connect the drain hose directly to our : existing home plumbing?Yes it is possible you should maintain a trap in the hose , under the laundry tub your ty connection should be on the sink drain between the tub and p-trap not after and the run up the side of the laundry tub to the same hight as the laundry tub. This is to prevent it from siphoning the drain on the washing machine.Good luck
