I have received instructions on how to drain my domestic system and then re-charge in order to eliminate water hammer in the system.
The procedure calls for shutting off the main supply and then turning on all faucets, water feeds etc. and then shutting off the water supply to the hot water tank. (gas-fired).
My question is, will this not empty the tank, and if so, won't it be damaged by the gas heating system trying to heat the empty tank?
