New washer, new hammer!
We replaced our old Kenmore washer with a new Kenmore washer and also had the plumber come and install new valves and a new laundry tub & faucet. Now we have hammer. I'm guessing the new high-efficiency washer has more aggressive solenoids or something because when it fills, stops, fills, stops, etc., it bangs like crazy. The copper pipes feeding the appliance are strapped down pretty tight and they don't seem to be moving, but the hoses (braided metal) are dancing around like crazy when this happens and, of course, the noise is annoying. What's the best approach here?
