I'm installing a new WH in the garage WH closet and must bring the installation up to code which means installing a drip pan and an expansion tank. I already have a 3/4" copper line for the T&P valve which goes through the exterior wall and drains outside.
I know the T&P drain line cannot go into the drip pan. That's not what I'm trying to do.
Per Code, can I "tee" the drip pan drain line into the vertical existing T&P drain line so I don't have to drill another hole in the exterior stone wainscoating? I would install a swing check valve on the drip pan drain line. Our town uses the 2003 UPC.
