I have a water heater drain pan installed and I'd like to terminate it as close to code as is possible. The pan/water heater is currently in a closet that barely fits the pan. So unfortunately, there is no way I can fit an indirect waste receptor. The water heater is also at ground level, so I don't know how I can get it to terminate outside above 6 inches.
Currently, it goes into the crawlspace. I could either tap it into the bathtub drain before the p-trap or terminate it outside but it'd basically be at ground level. Which of these is best to implement and why/why not? I'm also open to other ideas if anyone has any.
