My hot water heater seems to occasionally cause the water pressure to increase a lot. Is this what the expansion tank is for? If so how large is the tank and where does it go?

The expansion tank gives the hotwater a place ro expand. Check out expansion tanks at; http://www.accentshopping.com/store/...r/DET-5-M1.asp
And a typical installation,(see image). Good luck and ifyou have more questions I'm as close as a click. Tom
