I am working with a contractor that ran the water heater drain lines straight down into the middle of the the pier and beam area with pvc pipe. He says the water heater won't be leaking every day and that it doesn't matter whether the drain pipe runs out to drain into the parking lot, as we originally discussed.

I wanted to check in with you all, because this doesn't seem right to me. We bought enough pvc pipe and supplies to run the drain pipe out to the parking lot. Do I tell him to run it out to the parking lot? I am worried that if there is ever a problem, and the water heater floods, that it will damage the pier and beam foundation, as well as cause problems with the interior structure (wood), plus mold due to not being able to evaporate correctly. Is this a valid concern?

I am in Austin, Texas.

Thanks.

If you mean the pan drain: discharge can be in crawl space PROVIDING it is sand or sandy soil - the pan itself remains visible

If you mean the relief valve discharge pipe: ABSOLUTELY NO NO NO - discharge must be clearly visible, either to a floor drain OR through the wall to a VISIBLE spot outdoors, or to a funnel 'receptor' which is then itself piped outdoors


HOWEVER


YOU are the customer - YOU determine (code allowing) where what and how the plumbing is placed
