Thank you for sharing Robbbyr. I just had our Grayhawk in for warranty issues and was also advised that the "clanking" from the water heater is normal. We did replace the shower head with the Oxygenics shower head. Unbelievable water pressure from it! We open the hot water tap about 2/3rds and have experienced great hot water showers.
