i am looking to install only a washing machine (no drier) in my condo under the counter in the kitchen. my brother tried to install it for me but some plumbers advised him not to just hook it up because of the plumbing system 2 inch 1 and 1/2 inch... in any way i understand the concern but i just want to know if it is possible if i hire a professional plumber can they be able to change the whole plumbing system to accommodate the washer in the kitchen ? if it is easy to do it my brother can do it but how? i appreciate any comment.
