Customer had us out today for a dripping faucet in the mast bath. Replaced the cartridge in the lav on the right hand side. Turned water on and checked for leaks and functionality, everything is working as it should. Customer also had concerns about water c9ming from the dishwasher air gap. Removed hose from air gap and found a blockage. Cleared the blockag3 and everything is working as it should. No warranty on drain cleaning. We will need to schedule the QAC
