Soldering Water Valves
Summary: Should you solder water valves when they are open or closed? Correct soldering depends on the type of valve.
Hi Tim,
Do I leave the valves open or closed when you solder them in the line?

Hi Dave,
It depends upon the type of valve! If you are soldering a traditional valve that has a rubber or plastic washer, then you open it. It you are soldering a ball valve, you keep it closed.
Once the solder is set, you should try to slowly cool the valve body to stop the heat transfer towards the actual washer and ball.

Hi I am wanting to change my old bath tub tappes that are rubber washer to
washerless tappes but I don't know how to start. Can you give a few
pointers?

Hi Tim,
First off, I just discovered your website and it looks great! If any of your readers are installing Dahl mini-ball valves (compact ball valves), please note that they must be left OPEN when soldering. I cannot speak to other manufacturers' valves, but that is definitely the case with Dahl valves. Happy Soldering! Thomas Husebye View all comments |
