4 Ways to Avert a Water Heater Explosion

Water heaters can become a ticking bomb if not maintained properly. The explosion may be devastating or something minor. But either way, the safety of everyone in your household can be at risk. Even a small explosion that doesn’t entirely damage your house can still cost a lot of repairs. Here are some useful tips on how you can prevent a water heater explosion in your home.

  1. Set the thermostat between 48°C to 60°C

A lot of homeowners set their water heater at extremely high temperatures which is actually very dangerous. Raising temperatures above 60°C will only cause scalding and destroy the components of your water heater — especially if you do this in the long term. It’s generally recommended to have the thermostat set between 48°C to 60°C.

Please be reminded that each water heater is different. A 60°C may be too hot for you so you need to test out which temperature (within the recommended range) best fits your needs. Be careful not to set the temperature too low since this will inhibit bacterial growth. Take note these aren’t just some typical bacteria, they’re dangerous and can impair your health for a long time.

  1. Testing the TPR Valves

TPR (temperature/pressure relief) valve is a valuable part of your water heater. Whenever your water heater undergoes dangerously high temperatures and pressure it has a high chance of exploding. If this happens, the TPR valve will dispense water so that the temperature and pressure will stop building-up.

You can test the TPR valve on your own since it’s easy to conduct. Find the lever, switch it up and then let it slowly go back to its original position. Water should be flowing out of the valve when you’re doing this. If no water is coming out or it’s just small trickles then have it replaced.

  1. Having a yearly inspection

Sometimes water heaters are already showing signs of problems but it’s difficult to detect. A yearly inspection done by a water heater technician or a licensed plumber must be done. These experts will be able to recognise possible issues with the water heater, issues that you otherwise would have not known. They can also optimise and adjust your water heater to make it more optimal. Certain tune-ups may be needed for water heaters that are a bit too old. Last but not the least, their inspection will also include checking the safety mechanisms.

  1. Avoid doing DIY repairs for your water heater

DIY is best suited for simple plumbing and fixture repairs. Complicated fixes — especially for water heaters — are too risky for the average homeowner or to anyone who attempts these repairs without the required knowledge and experience. Doing repairs on your own can lead to the water heater improperly fixed and cause more issues in the long run. Let the professionals handle it to save you the time, effort, and risks.
