发帖数: 226 | 1 想修一下水龙头，需要把水断掉。 貌似如果是gas water heater， 开关还是挺讲究的？
ps， 能不能只把water heater 的出水阀关上，但是heater还开着。
谢谢~~！ |

will require a value for each faucet, but some area do not.
It should be ok to leave the water heater on (unless you plan to drain the
water heater completely). But if you want to be extra careful, you can just
turn it off it is electric or turn to pilot if gas.
的？

heater的补水管有止回阀的 |

heater 应该没有止回阀。

不会流出来？造成heater里面没水？ 或者因为气压的缘故，水流不出来？我没想明白
。。。
谢谢~！！

发帖数: 4125 | 7 Only a little will come out, but most will stay in the water heater, unless
you open a hot water faucet that is lower than the water heater and open a
another hot water faucet that is higher to allow the air in. (chance of this
happen is very small, but if your water heater is on first floor, if you
open the basement faucet to drain and open a faucet on second floor to let
air in, it could such all the water out depending on how the pipe was
plumbed, just like I said, very small chance could hap
