A dependable and efficient hot water system is a key part of any comfortable home. From those warm showers on a chilly morning to powering appliances like dishwashers and washing machines, your hot water system does a lot of heavy lifting.
But over time, issues like sediment buildup, leaks, or worn-out valves can impact its performance. Regular maintenance isn’t just about preventing cold showers; it’s essential for improving efficiency, reducing energy bills, and keeping your home running smoothly.
This post explores six important checks every homeowner can perform.
1. Check for Sediment Buildup
An often-overlooked culprit in most household water systems, sediment accumulates over time as natural minerals in the water settle at the bottom of the heater tank. This layer creates an insulating effect, forcing the heating element to work harder and reducing efficiency.
To check for sediment, listen for unusual noises or inspect the tank with a flashlight. Regularly draining a small amount of water from the tank and examining it for visible debris can give you a better idea of whether sediment is present.
2. Conduct Backflow Testing
Backflow occurs when water reverses direction due to unexpected pressure changes, potentially contaminating your clean water supply with waste or other pollutants. Performing backflow testing ensures that your water supply remains safe and hygienic.
Look at the plumbing for installed backflow prevention devices, usually positioned near your water meter or outdoor taps. With professional help, these devices can be evaluated for proper functioning to guarantee the safe flow of water.
3. Examine the Temperature and Pressure Relief Valve
Safety should always be a priority when managing anything that uses heat and water together. The temperature and pressure relief valve (T&P valve) is what prevents your water heater from turning dangerous in case of excessive pressure.
Perform regular checks by carefully lifting the T&P valve handle to ensure it releases water when activated. If it doesn’t, or if water continues to leak after testing, it’s time for a replacement.
4. Schedule Routine Water Heater Service
While some maintenance tasks are easy to handle, others require professional expertise. Routine water heater service ensures internal components are operating efficiently and helps you stay ahead of wear and tear.
Don’t wait for the heater to stop functioning; consider servicing your water heater annually to extend its lifespan.
5. Flush the Water Heater
Flushing the system periodically is one of the best ways to combat sediment buildup. Here’s how you can do it safely at home:
- Turn off the water heater and wait for the water to cool.
- Connect a hose to the drain valve and direct it to a drainage area.
- Open the valve slowly to empty sediment-filled water.
- Close the valve, detach the hose, refill the tank, and turn the heater back on.
This process improves the heater’s efficiency and reduces the likelihood of internal damage.
6. Inspect for Leaks and Corrosion
Leaks don’t just waste water; they’re a telltale sign of damage that could lead to costly repairs. Check the surrounding area of the water heater, connectors, and pipes for water puddles, rust stains, or corrosion.
If you spot any signs of rust, bumps on the tank, or active leaks, these problems likely require immediate attention. Repairs or tank replacement may be necessary depending on the severity.
