where to vent pressure relief valve if no access to outside


When we bought this house the pressure relief valve was not vented properly. It went down the side of the water heater into a hole in the floor and terminated into the crawl space. Inspector at the time didn't make too big of a deal about and merely said, "yeah, you'll want to fix that eventually".
I'm going to be putting in a new (energy star) water heater and would like to vent this pipe properly. Problem is, the water heater is kind of in the middle of the house inside a coat closet. There's no close access to the outside.

what other options do I have?

It should go to a drain. It is water that will be coming out of it. There will also be specs as the length of pipe and number of bends allowed.

I thought that was not to code? I know... makes sense to drain water into the drain line... but I thought that was a no/no.

Also, I think the length needed to get to the ABS drain pipes may exceed the limit.

Given the location of the heater, I'd still take the T&P into the crawl. Keep it in the joist area and pipe it out the rim joist. Once outside terminate it with a 90 pointed down. Keep it 6" above finished grade.
Codes very across the country so this may not be allowed in your area but we do it often.
If you're worried about length, you could always upsize to 1.5" pvc pipe.
