Plumbing – combo tee vs. tee wye


I saw on wikipedia a mention of "combo tee" and "tee wye" is there a difference or are they the same?

I've also heard of something called a "sweep" or "long sweep" is that related here?

Best Answer

The combo tee has a longer sweep. Long sweeps are easier to run a snake through and drain better as the water path is gradually changed (if you have the space to use them).
