I just replaced my electric water heater in the indoor laundry room. The old & new WH have a top TPR valve. The WH is in a corner with the left side and back up against a wall.
The original WH had the TPR valve drain pipe run through the wall in to the unheated garage and then through the exterior wall to the outside.
The house is in the mountains (in California) where it freezes/snows and I read code prohibits any part of the pipe being exposed to freezing. I also do not have a floor drain.
Can I run the pipe to my utility sink? I'm thinking no as the flood level of the sink (rim of sink ) is 34" above floor (the bottom is less than 24" from floor).
Does code allow me to run it to a bucket underneath the sink, like this example I found?
I would be hard pressed to squeeze in a floor drain. I've never had water freeze in the garage so maybe keep the pipe inside the garage to discharge down to the cement floor? Or is re-attaching it to the existing pipe the best option?
Thanks in advance for any help.
