Hot water is something we can’t do without daily, yet it’s easy to overlook the importance of keeping your hot water system running efficiently.
Keeping your hot water system in good nick not only cuts down on energy bills but also spares you from costly repairs or replacements. Still, many find it tricky to maintain their systems properly.
Hence, we have curated this informative guide on hot water system maintenance. We will share practical tips on preventative measures and troubleshooting common issues.
These tips will help you get the most out of your hot water tank. Let’s dive into it!
What Maintenance Does A Hot Water System Need?
To maintain your hot water system, you need to know about the two elements of the device. These are:
1. Sacrificial Anodes
Inside most hot water systems, there’s a metal rod known as a sacrificial anode. It’s typically made from aluminium or magnesium and coated with zinc. Its job is to attract impurities and minerals, making it crucial for hot water system maintenance.
Without this rod, your water tank will collect all the impurities, causing it to rust and deteriorate. As the name suggests, the rod sacrifices itself for the good of your hot water system. So, when you notice the “sacrificial anode” rusting, you must replace it with a new one. Replacing the rod can be dangerous as it involves dealing with hot water and gas or electric lines.
So, it’s best to ring a professional to replace the “sacrificial anode" rod.
2. Temperature And Pressure Relief Valves
The other important element of your hot water system that needs regular maintenance is the temperature and pressure relief valves (TPR). The TPR valves function as a safety measure for the hot water system.
Extreme hot water can cause the tank to split or even explode due to pressure buildup. That’s where the TPR valve comes in handy, releasing excess heat and pressure.
You can check the temperature relief valve with these simple steps.
- Check for any leaks; if any, you have to replace them.
- You must gear up for safety with long pants, gloves, and covered shoes, as you must drain hot water from the tank.
- Ensure that the area below the outlet pipe is clear of any obstructions.
- You can then gently lift the handle on the TPR valve but only apply a little force if it’s stuck.
- Stand as far as possible from the hot water unit as a secondary safety measure.
- As you lift the handle of the TPR valve, hot water will pour out of the outlet pipe’s opening.
- Gently lower the handle back to close the outlet pipe once the water temperature and pressure are low.
- If the outlet pipe doesn’t close, you must replace the valve.
- Last, hire a licensed and fully qualified plumber if the temperature and pressure relief valve needs replacing.
Tips On How To Maintain Hot Water System
We recommend following these tips to maintain your hot water system.
1. Check The TPR Valve
- Cut the power off and stop the cold water supply.
- Place a bucket under the pipe connected to the temperature and pressure relief valve.
- Lift the TPR valve to let some water out, then let go.
- If water still flows after that, unscrew the old valve and replace it with a new one.
2. Draining The Tank And Removing Sediments
- Drain the tank into a bucket and remove all water.
- Remove the remaining sediments by stirring and temporarily turning on the cold water supply.
- Repeat this process until the tank is clean.
- Close the drain cock and refill the tank; you can also turn the power on.
3. Insulate The Pipe
- Buy some 3/8-inch thick self-sticking foam pipe insulation matching the diameter of the pipes.
- Slide the insulation foam into the hot-and-cold water pipe as far as possible.
- Peel the tape and close the insulation by squeezing.
4. Insulate The Heater
- Cut the insulation blanket according to fit around the TPR valve, pipes, and temperature control tank.
- Wrap the side of the tank with the insulation blanket and seal the cut with foil tape.
- Cap an electric water heater with an oversized circle of insulation and tape the edge properly to the side of the tank.
Keep Your Hot Water Flowing With Ease!
Long story short, getting your hot water heater serviced regularly is essential. Otherwise, the tanks may explode, which can be dangerous if anyone is nearby.
Now, heat pump water heaters may require you to have the temperature pressure relief valves replaced over time. However, replacing water heater parts can be challenging. As such, you must hire experienced plumbers to get the system serviced.
