Also meant to ask about drain pans:
Haven’t had a drain pan below the old water heater but want to add one now. The manuals I’ve looked at make a point of identifying a metal drain pan. I’ve been told that new construction in my area comes with a plastic drain pan. What are the pros and cons of going with one style over the other?
Sorry, this topic got lost when I originally posted. Should have previewed first and wouldn’t have had that post truncated…
