I need to connect into my existing plumbing to add a clothes washer drain. Hopefully this lay out explains what I need. I need to know if I will be putting in P-trap in right location? And do I need to put in a cheater air pipe to eliminate backup or drain off of P-trap, because of kitchen sink being high elevation than washer, or other cause?? If I need cheater air pipe where do I place it? I only plan on putting in a pipe connection to put my washer drain into, do not want to put in a wash tub as I do not have the space available. Any advice is appreciated. Thanks in advance.
