"normal" way to route water heater pressure relief

[geoffhazel]

I'm installing a new water heater in a daylight basement. It's about 12 feet from the wall where the exterior door is located. I figure I need to run a line from the heater to and through that wall and then right angle down to some distance off the ground. The wall the heater is on is a foundation wall that's been furred out with 2x4 wall.

What would be the normal setup for the pressure relief line? Inside the wall, or outside? Pex, pvc, or copper?

sadly, this is a new water heater to provide water to an addition that's too far away from existing supply.

if you read the relief valve tag it will tell you max developed length and the number of fittings you can use

why cant you pie it to the basement floor??????

Run it in copper to the outside w/ a 90 pointed down. Termination is no lower than 6” off the ground and no higher than 18”

you need to run 2 lines, a 1'' pvc pipe for a pan drain and a 3/4 cpvc or copper line for the relief valve
the water heater can not sit on the floor, it must have a minimum 3 1/2'' concrete pad under it

Is a pan required in a basement?
