We want to relocate clothes down washer to basement. Water supply and electricity is no problem. However, the existing 2 inch copper waste pipe runs along side the rim joist at 7 ft above the floor then into the main cast iron waste pipe. Will the washer's pump be strong enough to pump up that 7 ft height to the copper waste pipe or do I have to bust into the cast iron main waste pipe to drain the washer? Thanks.

There's no doubt in my mind that today's more powerful washer pumps will pump a 7 foot head. However, there will have to be modifications. You will have to cut into the copper waste line with a wye or combination wye and eighth bend cocked on a 45 degree angle, line itout with a street 45 and then a AAV,( air admittance valve to vent) and then a trap, raiser and a compression fittong to make it a closed system. You will also have to install a hose check valve on the outlet of the washer to prevent all the dirty water in the hose from draining back on your clean wash after the pump shuts down. There will be more questions so ask away. Regards. Tomn
