Alpha Plumbing replaced a power vent water heater (pictured left) for a customer in Annapolis. You can see the expansion tank required by code and the blower assembly that blows the exhaust through the vent pipe. You can also see the pan piped to the sump pit. Alpha Plumbing also installed a recirculating pump with a timer and Aquastat. The recirc pump ensures immediate availability of hot water to the plumbing fixtures, while the timer allows the homeowner to control what hours the pump is running. The Aquastat prevents the pump from running unnecessarily.
