Condensation Lines/Drip Pans

About a year ago I had an HVAC complany install a new heat pump and return in my attic. My old system was at least 18 years old according to the technician. When the new system was installed, the HVAC company connected it to the existing condensation lines and drip pan which are made of metal rather than PVC. A city inspector came out (Sacramento, CA) and the work passed inspection.

I've since had a leaking problem and extensive water damage. I'm wondering if someone knows if the industry standard is to use existing metal condensation lines and drip pans or would industry standard have required replacing the 18 year old items with new items? Is PVC technically the code? Should the inspection have failed? Any info on this would be helpful. Thanks!

Condensation Lines/Drip Pans

Any time I replace a air handler and coil in a old system.I would make sure to clean out the drain lines.copper or pvc.Most of us use pvc because it is cheaper and quicker to install,commercial applications may require copper for a drain in some places.As for emergency drain pan.metal or plastic is used all the time. depends on what the contractor likes to use.I personally made my own drain pans in the shop.But now I find it easyer to just buy the plastic type.The down fall with metal,if it gets wet it will years later start to rust.Plastic after many long years in the hot attic it starts to get brittle.Allso when you have to deal with the inspecter and what he LIKES.
