If your water heater is 10 years old or more, it's much better to replace the entire thing before you start having additional problems with it. You MAY be able to drain your water heater and replace the valve with something more reliable, but, as I've said... if your water heater is old, this is just the 1st thing to go wrong. More will follow.
