how to get the right Pressure Relief Valve
Depending on your model of water heater, you could have either a very easy or very hard to replace pressure relief valve. These types of valves need to be replaced when they are no longer able to withstand the excess pressure of your water heater. So while it is easy to know if something is wrong and to know where to find it, they are not so easy to physically replace.

Most models have the valve attached to the discharge pipe coming out of the top of the water heater. Likely it will be the only thing attached to that one pipe. If you're not exactly sure what one of these looks like, you can simply look online for your water heater model and find some pictures.

You can also look online to find out about the valve that you need, or take it into your local hardware store to be pointed in the right direction.
