Is it possible to connect a T-connector to the ACCOR, one piece angle stop

At what end ? At the incoming supply side or where water supply connector connects ?

But, basically, answer is Yes, you can connect T to angle stop. If you tell us more about what you plan on doing, we can then give you more precise answer.

Like Milo says, Where do you want the tee to go. On the supply from the stop or on the stubout ahead of the stop? We're waiting! Cheers, Tom
