I live in a large Travel Trailer and would like to have more space beneath the sink for storage.
I'm buying a top mount rectangular vessel sink with hand pressed pop up drain plug no mechanism from taps to drain.
My question. Can I run a 90 or 60 degree elbow to short straight pipe from the sinks tail pipe to the trap?, A second 90 again to trap so it can fit tight to back wall, then slight angle down of connecting pipe going into the main drain/vent stack?
Does the trap need to be attached directly to and below tail pipe or as I propose, can it be bridged 8 to 10 inches away then surface mounted on wall... providing its installed at same height under sink it would normally be?
