I had a plumber over a few months ago to change a vavle. He shut the water off in the basement. He said you have to shut it off and then turn it on in order so that there is no air in the system. Can anyone let me know that order? Also, I have two levers (on the right and left), which one is supposed to be to street and which one to house? Thanks
Don't sound right to me usually the air will be pushed right through a system and out the spigots without problems unless he was working with the closed heating system then air could cause some problems. The valve from the street would be the first valve coming through the wall the other valve should be the secondary house shutoff.
