new install, slow drain
Posted by Don on February 06, 2003 at 23:05:28:
I've just installed a new , imported from France ceramic sink that sits above the countertop. There is no overflow, only 1 1/4" drain. The line provided makes immediate 90 degree turn to the back of the cabinet, so p trap is not visable underneath. The run is app. 12" and it makes a 90 degree down turn. I placed a flex pipe to a flex p trap behind the cabinet which connects to the 1 1/2" original pipe into the wall. The system drains very slowly. Is it because of the 1 1/4 pipe, lack of overflow or what?
