How Your Plumbing Habits Could Be Driving Up Your Electric Bill
If you live in a place where temperatures swing from one extreme to the other, you’ve probably noticed your electric bill climbing during the colder months—and possibly again during those hot summer days. It's hard to ignore the chill when you get out of bed in winter or how those warm showers start lasting longer when it’s cold outside. But beyond the changing seasons, have you ever thought about how your plumbing system and daily water habits might be quietly raising your electricity costs?
Let’s break down some common plumbing-related issues and simple ways you can start using energy—and water—more efficiently.
1. Hot Water Leaks: The Hidden Energy Hog
A major (and often overlooked) culprit of rising electric bills is a hot water leak in your electric water heater. If your utility costs have been creeping up and you can’t quite explain why, this should be one of the first things you check.
-
Start with the Temperature & Pressure Relief Valve
Located near the top of your water heater, this valve can deteriorate over time and begin to leak. If you see water dripping from the pipe that leads from this valve to the ground, it’s likely time for a replacement. Never cap or plug this pipe—a leaking valve should be replaced, not ignored. -
Inspect the Base of the Tank
Sediment buildup at the bottom of your tank can cause corrosion and lead to leaks. Prevent this by draining and flushing your water heater at least once a year. -
Check Inlet and Outlet Connections
These can loosen over time. Tightening them with a wrench may stop small leaks. If you find a crack in a pipe, it’ll need replacing—but the fix is usually straightforward. -
Look for Faucet Drips and Under-Sink Leaks
A constantly dripping faucet or a leaking supply line might seem minor, but over time they waste hot water—and energy. -
Watch for Slab Leaks
Leaks beneath your concrete slab foundation are harder to detect. Warm spots on your floor could be a sign. These usually require professional help, but catching them early can save you from costly repairs.
2. Smarter Water Use = Lower Electric Bills
Your water habits—whether you live alone or with a big family—can have a big impact on your electricity use. The good news? A few small changes can make a noticeable difference.
Be Strategic With the Dishwasher
Running a half-empty dishwasher may be convenient, but it’s also wasteful. Each cycle uses around 6 gallons of water and a chunk of electricity. Try to wait until it’s full before running it. Even reducing a couple of unnecessary loads per month can make a difference.
Take Shorter, Smarter Showers
Long, hot showers feel great—especially in winter—but they also make your water heater work overtime. Cutting your shower by just a few minutes can save gallons of hot water and lower your energy use. Bonus tip: Install a low-flow showerhead for even more savings without sacrificing water pressure.
Reconsider Your Lawn Watering Routine
A lush lawn looks great, but it can be a silent drain on your water—and power—usage. Overwatering or running sprinklers too long is common. Consider a drip irrigation system for gardens or flower beds—it uses far less water and can help reduce your electricity use tied to water systems.
Final Thoughts
While you may not think about it every day, your plumbing system and water usage are closely connected to your electric bill. From hot water leaks to inefficient water habits, small issues can add up quickly. The good news? Most solutions are easy and inexpensive.
By taking a little time to inspect your plumbing and adopt smarter water practices, you can reduce your energy usage, protect your appliances, and keep more money in your wallet—all while being kinder to the planet.
