A check valve (or backdraft damper) sits inside your vent line and is designed to keep outside air, pests, and Phoenix dust from flowing back into your laundry room — but lint builds up on its flap over time and can hold it partially open or stuck shut. At Pure Air Service, we inspect and clear check valves on every cleaning so airflow stays strong and your home stays sealed against our desert heat and dust. Give us a call at (623) 552-3176 and we’ll make sure yours is working exactly as it should.
