The water company plans to install water meters in area of my summer cottage sometimes this winter. I assume that they will add anti-backflow device, so I will need an expansion tank this spring. The electric water heater is 50 gal so I expect to use a small tank. All plumbing is ½” copper and I am comfortable installing tank myself but the water heater is in attic so overhead space is limited. I imagine mounting tank vertically alongside of heater using a ½” T on cold supply to elbow to ¾” FIP adapter.
All pipes are drained each winter. If I mount with air valve up will tank drain to prevent freezing damage over winter?
Is ½” copper strong enough to support or should I add additional bracket?
Does it matter if valve is upstream or downstream of tank?
