Never, ever, block the TPR valve on your hot water heater!

Have a look at this video of the ‘Myth Busters’ to see what happens if you block the Temperature Pressure Relief (TPR) valve on your hot water heater.

The TPR valve plays a very important role in keeping your hot water heater operating correctly and safely.  When the water heats and expands inside the storage tank, ready for you to use, the job of the TPR valve is to relieve the pressure by allowing a little of the water to escape.

It’s so common for householders to think there’s an issue with their hot water heater if they see a few drips, and they attempt to tape it up or block it off somehow.  It’s a deadly rocket in waiting if that’s done. If there is a continuous trickle or a heavy flow of water, you need to have your hot water heater looked at, but if it’s just a little drip here and there, leave it alone!
