After getting a new washing machine, we were getting a horrible pipe banging when the water intake turned on/off quickly. I installed water hammer arrestors on the faucets that the washing machine is connected to, which stopped the banging.
However, now after a couple of months, when the washing machine starts up, there is a loud squealing when it initially takes in water. I'm assuming it is related to the water hammer arrestors, but I'm not sure. Any ideas on how to address this problem would be appreciated.
