Review on Efficient Heating with Four Seasons 74604 Heater Valve by Brian Mendoza

Revainrating 4 out of 5

Heater Valve: Heat

Seems to be working as it should but time will tell. My only complaint, if you want to call it that, is that there is no entry/exit designation and I was told that the entry is the long (low) end. Of course I installed it backwards because it was easier for my particular setup.

Pros
  • Part Number: 74604
Cons
  • Zero
