Ok so I am working on changing our washing machine drain method from in to our old sink to a Wall Receptacle with Brass 1/4 Turn faucets. I feel comfortable in my ability to run the pipes over however. As you will notice in the below picture I need to move the drain pipe up higher to get around an electrical outlet. My question is, is it safe to tie in to the Vent pipe you see in the picture about 2 feet up from the existing drain and remove the existing drain? if you don't understand what I mean please let me know and I will try to explain it better.
