I had a leak in ceiling of my home built 20 years ago. Upon cutting into sheet rock I notice Genz Ryan did not glue or use proper connections in kitchen drain ABS pipe. Great job guys! NOT Had to open up ceiling in 3 place to find other non glued conections as doing repair on first noticed pipe to spin so no glue on connections. WOW.....
