My water heater has its pressure release valve routed into the crawlspace. I was flushing it and had to open the valve to get it to fill. It got too full, and started releasing cold water into the crawlspace. There's a small puddle under there now. Should I be worried about this? Is there anything I can do to prevent mold or critters from taking advantage of this? Should I pour some bleach in there? Hoping to avoid disaster!
