Hi:

Need some advice on this. We have an older mobile home, 1973.
Currently on our second hot water heater, installed about 13 years
ago. It is a natural gas 30 gallon unit. The temperature is set at a
low-warm about 120* I am getting a slow but constant discharge
from the temperature/pressure release valve. The drain line goes
thru the floor and discharges under the home.

What now?
