Confusion on the play, Bob.

[FishScreener]

I‘m trying to help, my sister with her townhouse. Before he passed, her husband replaced al of the lavatory faucets with Moen, Adler units.

Here is where the confusion begins: If I run the faucets in the master bath until they get hot, the flow shuts off. Same units in the hall and downstairs bath run just fine, regardless of the temperature.

I looked underneath at the feed lines and everything looks normal, no thermostatic valves, or any thing else. Copper out of the wall, with the stop soldered on, appears to be a very good solder job, then a hose to the hot side of both faucets, and same for the cold.

Is there anything you can think of which would cause this behavior?

thanks, Jigs.

Remove the hot supply line leading to the faucet to determine if hot water comes out of it.
