If running on the water pump, you will get hammering if air is trapped in the lines. Bleeding at all of the faucets should improve the sound. Some noise from the pump is normal.

Actually, this is a common problem...we have had it in last 3 AS's...we just took our 28 to Jackson Center, and they replaced the waterpump...I had insulated the pipes that were "pounding" on the floor, but could not get to all of them. Also, I had some air leaking, I suspected. they replaced my pump with a new pump and pressure checked the noise!
