Noticed some dripping on the outside of the rig and upon investigation found a small amount of dripping water coming from the pressure valve off the hot water tank. It has been warmer than it has been in a while-could that have something to do with it (we haven't noticed it before)? If no, is this a big deal? There is some rust on the pipes, so replacing them would probably be a good idea, just wondered what might be happening.

Happens to me sometimes. The tank works best with a small air pocket at the top of tank. I don't know what causes it, but the air pocket will disappear and the pressure valve will drip. Makes a great excuse to flush the tank. If it still leaks after you flush the tank then you can replace the pressure valve, costs about $15 for a new one.

Nope, not a big deal.This happens when the pressure in the tank reaches the pop-off set point.Sometimes this may happen more if you have lost your “air balloon” in the top of tank.That is the top of the tank has filled all the way up with water and the air has totally been evacuated.To replenish the air, just drain the tank and fill it. Nope, not a big deal and is normal.Happens all the time.

If you drain your tank and refill it and the drips continue, then the valve may be leaking slowly allowing the air pocket to seep out. If it continues after the refill, it is a good idea to replace the valve. If you do be sure to use an anti-seize material on the threads.
