I had a similiar problem .Iinstalled a tee with a arrestor and it worked But also see if you have a pressure reducing valve, it may be bad, I had city water pressure at 150 and the reducing valve failed .something to look at

47-2 lwco with autofill hammering at end of feed
Hi, I have a customer with a 47-2 lwco and autofill (both brand new) that, at the end of a feed, begins to flutter or hammer the inlet water line loudly. My guess is that because of the mechanical design of the fill, it does not shut off immediately like a solenoid type. Will a water hammer arrestor solve this? It flutters for a good 20 seconds. thanks, scott0 -

Try disconnecting the piping on the boiler side of the LWCO and check for restrictions. You'll probably find a scale build-up right at the nipple that enters the bottom of the boiler. Clean and flush this conection. Usually this causes the boiler to overfill. You could also do a broken union test on the LWCO. If he valve closes with out hammerring during the test, the feeder is OK and start looking for the restriction.0 -
incomming water pressure
Try throttling the incomming water valve down. Too much pressure will cause this.0 -
I agree throttle it down
and also make sure all the piping is secure. Some good pipe insulaTION and strapping will quiet things down too./ M ad Dog

Make sure that your piped in properly. If you pipe it in backwards you'll get the same flutter while it's trying to close.
