here are some pics of the drain system I made up, 1 1/2 pvc is perfect match for the drains. Iused fernco connectors at the drains and outlet 1 1/2 X 1 1/2 for the drains 1 1/2 X 1 1/4 for the outlet. 1 10ft piece almost did both sides, I have to get a remnant tommorow. Port side is complete
starboard needs one piece about 20" long
