Water Heaters: TPR Valve Tips To Help Reduce Risks Of Scalding

Posted on: 5 May 2016

Most water heating systems are closed systems. As a result, when a heater's temperature increases to an abnormally high level, thermal expansion takes place, something that then increases the risks of water heater explosions. This is where a TPR (Temperature/Pressure Relief) valve usually comes in handy.

The TPR valve usually provides an opening that allows the extra volume of water to escape. It therefore relieves the water heating system of the extra pressure resulting from thermal expansion hence reducing the risks of water heater explosion – something that might expose your loved ones to risks of scalding. The following are TPR valve tips that will come in handy in helping you protect your loved ones from scalding risks.

Make sure that the valve is functioning

Given the role that the TPR plays in helping to prevent water heater explosions, making sure that it is functioning as effectively as it should is key when it comes to increasing the safety of your loved ones. An easy way to do so is to use the TPR lever test.

In order to provide a way for homeowners to manually relieve a water heater's pressure in emergency cases, manufacturers usually fit water heaters with a TPR valve lever. And since the lever is directly connected to the TPR valve, pushing it should open the lever.

When you push the lever, you should be able to see water jutting through the valve. If nothing happens, you are likely dealing with a defective valve. Replacing it as soon as possible is necessary if you want to increase the safety of your home.

It is also advisable that you make sure that there is nothing obstructing the movement of the lever. Why? Because the lever is connected to the TPR valve and anything restricting its movement is likely to mess with the operation of the valve. Remove any physical objects that may be next to the lever. Positioning the water heater in such a way that the lever doesn't press against the wall will also help in reducing the risks of a TPR valve malfunction.

Install a discharge tube

The TPR valve usually accomplishes its explosion-preventing role by emitting hot water and steam. These emissions can end up injuring an unsuspecting loved one.

To make your home safer, it is advisable that you install a discharge tube. This tube will come in handy in helping to guide the hot water, emitted by the TPR valve, to your drainage system and thus reducing the risks of scalding.

Diagnosing Plumbing Issues

After we moved into a new home, I could tell that the plumbing system was having problems. Our drains never really drained quickly, and there was always the faint smell of sewage in the background. I knew that I wanted to fix the problem, but I didn't really know where to start. However, I knew that I didn't want to take care of the problem, so I called in the experts. My friend, who worked as a plumber, came out and worked hard to diagnose the issues. After we got things fixed, our house smelled and functioned better. This blog is all about diagnosing plumbing problems.
