There could possibly be sediment on the bottom of your WH, try to flush the tank from the WH drain valve until the water runs clean. An indication whether or not you need an expansion tank would be a leaking relief valve on the WH. You can always test your water pressure with a gauge hooked up to a hose bibb, (garden hose threads) a normal reading would be under 80 p.s.i.
Have a licensed plumber inspect the system.
