I have two pvc pipes coming off my water heater to the exterior of my home that continue to drain water into my yard. One is for the relief valve and I replaced the relief valve. What is the other one? It continues to drip causing a puddle on my lawn. What would cause it to continuously drip? Is that normal?

If you post a picture will help, Thanks.

There are only 4 "exits on a water heater;top intake and outlet. T&P valve and the drain valve. Where is your extra pipe connected? Betting it's the drain valve.
