Most homeowners know where the thermostat is. Almost none of them know the answers to these three questions. π π§
We ask homeowners these questions every week. And almost every time, the answer is "I have no idea." Here's what you should know about your own plumbing β and why it matters.
How old is your water heater?
The average tank water heater lasts 8 to 12 years. If you don't know when yours was installed, look for a sticker on the side of the unit β the serial number usually contains the manufacture date. If it's pushing 10 years or older, it's not a question of if it will fail. It's when.
When was it last flushed β and what did the water look like?
Water heaters should be flushed annually to clear out sediment buildup. Most homeowners have never had this done. When we flush a neglected water heater, the water that comes out is often brown, cloudy, or full of visible debris. That sediment is sitting at the bottom of your tank, reducing efficiency and shortening the life of the unit.
What does the service line to your septic look like?
If your home is on a septic system, there is a pipe running from your house to the tank. Most homeowners have never seen it, don't know where it is, and have no idea when it was last inspected. Tree roots, grease buildup, and age can all cause that line to fail β and when it does, it is one of the most unpleasant and expensive plumbing emergencies a homeowner can face.
You don't need to be a plumber to own a home. But knowing the answers to these three questions could save you thousands.
