Last year I bought this 16 year old house. It has a new furnace, 2 years old. I have read some info on zone valves. Some suggest putting them on the return end of the loops, some suggest a hammer arrester, or seperate circulator on each line and some suggest putting in a differential pressure buypass. I tried removing one of the springs on each Honeywell v8043 but that didn't help much. Any thoughts out there to what is the best to do????
