Plumbers, should I turn off my water?

A new water distribution line was run down my street, replacing the 80 yo original. I received notice my house will be switched from the old to the new line tomorrow. They will be cutting the supply line on the house side of the meter.

So when they do that, I assume the bulk of my house lines will drain. Thus when reconnected and I turn on a faucet for the first there will be a ton of air in the lines.

Does it make sense to turn off my main shut off in the basement, thereby isolating the house pipes?

Once the pressure in the lines is released, it should airlock and not drain a whole lot if all of the faucets are closed. I’m guessing they’re not gonna bleed the new line all the way to your house so you’ll probably still have some air work it’s way through.

You might want to flush the line out via an outside garden hose once new connection is made. No sense in pushing gunk into the aerators.

Good call. And I have a spigot that taps the house main within a foot of it entering the house.

Remove all your Aerators and run for a few minutes to remove any debris when your reconnected.

I would shut off. I’ve seen a lot of debris get into supply lines. Then flush from the hydrant.
