They are not that expensive, but if you have the time and curiosity, you can take it apart.
I once took one apart and cleaned the sealing o-ring, and that stopped a leak. And the o-ring can be replaced. Also, as I recall, the connection in the back is similar to a kitchen supply hook-up with a conical washer. If it got screwed down too tight, it can deform and lead to leaks. Both of these leaks can be intermittent, particularly when your water heater has lost its bubble (and you don't have an accumulator) and it over-pressurizes your system.
