BANGING ZONE VALVES

As it does, it trips the end switch and stops the circulator. Standard stuff. The banging begins when two zones are calling at the same time and then one zone valve decides to close while the other is still open. As the valve closes on its springs the other valve keeps the circulator running because it still needs water.

TANKLESS WATER HEATER DISTANCE TO DRYER VENT? It’s > 12 inches from grade and > 12 inches from inside corner but I can’t find natural gas code details on direct venting gas appliance distances from dryer vents (if any such requirements exist).
