Arrived onsite met with customer and went over scope of work, reworked kitchen sink drain line to make it proper, cut out existing drain line and started from scratch, used a 2x1-1/2†reducer bushing to tie into 2†kitchen line and get It as close to the wall as I could, reinstall new drain line with master trap, once completed tested by running water down both sinks for a few minutes a piece, once completed put silicone around lavatory faucet handles to stop water from dripping threw small gap. Everything is working as it should.
