Testing And Troubleshooting
If you’re planning to install two water heaters in parallel, testing and troubleshooting are crucial steps to ensure that your project is working efficiently. By doing so, you can save yourself from costly repairs and potential damage to your home.
In this section, we will delve into the essential steps you need to follow to test the water heaters and troubleshoot any common issues that may arise during installation.
Testing The Water Heaters
To test the water heaters in parallel, you should follow these steps:
- Turn off the electricity or gas supply to the water heaters before you begin testing.
- Turn on the cold water supply and let the tanks fill completely.
- Once the tanks are full, turn on the electricity or gas supply.
- Set the temperature of each tank to the same level. Ensure that the thermostat readings of both water heaters are accurate. If you notice any issues with the thermostat, replace it.
- Turn on the hot water supply of both tanks and wait for some time. Check the temperature of the water coming out of both tanks. It should be at the same temperature.
- Test the pressure relief valve of each tank by lifting the valve lever. Water should flow out of the valve and stop once you release the lever. If there is no water flowing, replace the valve.
Troubleshooting Common Issues
Installing two water heaters in parallel can be a complex task. However, various issues may arise during or after installation, which you need to troubleshoot. Here are some of the common issues and how to resolve them:
- If there is no hot water from either tank, check if the circuit breaker is on and if the thermostat is working correctly.
- If the temperature of the water is too high, check the thermostat settings and adjust them accordingly.
- If there is an unusual noise, it could be due to sediment build-up. Drain the tanks to remove the sediment.
- If you notice a leak, turn off the water supply and check the connections for any loose parts. Tighten any loose connections and replace any damaged parts.
Testing and troubleshooting your water heaters is an essential step to ensure your installation is successful. By following these steps, you can minimize the chances of costly repairs and prolong the lifespan of your water heaters. Remember to contact a professional if you encounter any issues that you cannot handle yourself.
