View Full Version : Old shower pluming to new delta valve

Hell all,

I am not a plumber, please go easy! :)

I am doing a bathroom renovation and want to replace the existing 1960 shower plumbing with modern style Delta single lever valve and trim.
The pic shows the existing pipe work and the new valve I want to use.My question ....are there threaded fittings that will allow me to connect where the supply lines unscrew to the threaded input of the valve?

Thanks in advance

You should be sweating your connections. Compression fittings behind a wall are a no-no and are a terrible DIY way of installing a valve to old copper piping.

If you are planning to sweat your connecitons, and are unsure how to transition to the valve...the copper tubing actually slides into the inside of the threaded ports giving you the option of sweating the connection directly.

The unions on the old faucet are proprietary and there is nothing that fits them, other than another valve just like it by the same manufacturer.
