at WATER HEATER AGE & MANUALS you've found an article on water heater age. Search InspectApedia.com for AIR CONDITIONER AGE for help on A/C units. There you'll read about de-coding dates in the serial number depending on the A/C brand.

Question: what about water cylinder tank warranties?

Sharon see

The warranty period and terms of your specific water tank depend on its model, age, and of course proper installation. Typically you can find that information in the installation manual and papers for your unit, or if you don't have that information, you'd contact your heater's manufacturer and give them the model and serial number of your water heater.

Question:

We are worried about our hydronic water heater. Our neighbors had severe water damage when their water heater had a major leak while cold water kept flowing into the heater. Their system is similar to ours.

We are going on vacation and wonder if we can turn off the cold water intake so that if the water tank develops a leak, at least we won't have a flood. Can we do this safely?

We just moved into our home about three years ago and the hot water tank is giving us problems.

I would love to know how old the tank is. If it's really old that's understandable that it would give us problems, but it looks kind of newer. Hopefully we can just get it fixed and wont need to buy a whole new one.

Thank you.
