First thing to do - replace pressure relief valve on water heater. It's a cheap fix. They're usually rated between 45 & 75 PSI, so if your pressure is only 45, the valve is probably bad. If you've had grit, etc. in your water (anytime)it can get in the valve and cause havoc...(make SURE the water is coming from the Pressure valve, and not somewhere else - you could have a leaking tank if its older...)
FYI, on houses with City water where the pressure is high (150 psi), Pressure REDUCING Valves are installed on the main line coming into the house to reduce it back down to 50-60 psi. If you have one of these, (you probably don't if you're on a well - check), it could be going out. You COULD try one of these instead of the expansion tank if your problem doesn't go away with the replaced Pressure Relief valve. They're a lot cheaper than an expansion tank (about $40,) and are pretty easy to install, depending on the type of pipe you have and they last a long time...
Sorry for waxing - I used to do plumbing...
Good luck with it!
