Thompson Plumbing, Heating & Air Conditioning came out and met with Pam regarding master shower not draining, Pam also stated that water would come out of air gap during dishwasher use. Snaked shower drain line 25 feet, removed hair from drain line and cleared stoppage. In kitchen removed and cleaned 7/8” hose, reinstated and ran a quick drain cycle to ensure stoppage was cleared. At this time both fixtures are working as designed. Thank you for choosing Thompson Plumbing, Heating & Air Conditioning
