Question - should thermostatic mixing valves (specifically a Honeywell AM-1) produce any rattling noise when installed at a hot water heater?
A few months ago, we had our hot water heater replaced and as part of the install, a thermostatic mixing valve was added to regulate output water temperature. The valve makes rattling noise whenever hot water is running, which can be heard throughout the room that is adjacent to the water heater (it's in a closet with a louvered door).
I've gone back and forth with the installing company and they have not given me a straight answer. Honeywell said this could happen with recirculating pumps or similar, but our water system is very simple - no recirc pumps or anything else like that.
Thanks for any thoughts from anyone who has had a mixing valve. This is the first time I've had one of these valves. At this point I might just end up replacing it myself, but want to make sure I won't have the exact same issue with a new one as with the old one.
