I need to install my tpr pipe to go outside and I just wanted to make sure I did it correctly. The water heater is on an outside wall. Do I put any kind of a union before it goes in to the wall? Is there any kind trim piece I need to buy to make it look decent on the outside of the house?
The siding is a vertical tongue and groove. It looks kind of like t111 but its individual boards...... but it will eventually get replaced by hardi plank lap siding
Its an old house. The siding is installed over 1x6 planks that measure 3/4". The siding is also 3/4", but like I said, I'm going to replace the siding with hardi plank
Then it overflows at the air gap..... :jester:
My neighboring city of Spokane wants the air gap just for that reason.
If you have a dripping relief valve, the dripping water may ice shut during our not-so-rare, zero degree weeks- as it hits the exterior point.
Now, if that valve should then decide to discharge at 100% it can relieve at the air gap instead of against an ice dam.
BTW- only a short section needs to be 2 diameters larger (1.25") This is to indirectly receive the 3/4 line from the valve. The rest of the indirect line to the exterior can be 3/4"- Like a funnel....
Ghost's code will probably be different- he's not out west like us......:jester:
Is there any reason this can't be run inside my wall? I was going to run it inside the wall before I drywall, but the home depot guy said it must be run on the surface of the drywall.
