The cold intake pipe for my water heater has a drain valve with plastic tubing leading to my basement drain. This tubing always has a constant flow of dripping water; basically, my water heater's cold intake drain valve is ALWAYS dripping. I've NEVER seen it not drip.
Is this normal? I ask because my sump pump goes off like clockwork every 3 hours and I'm beginning to think its due to this dripping. I thought we had a water table underneath our house because unplugging the sump pump for days at a time doesn't cause it to overflow.
