When the relief valve on the boiler is not holding it is time to take immediate action. If you are unaware of the signs that your relief valve is failing, please read on. First of all we need to understand the signs that your pressure relief valve is failing, then we will explore the reasons why you pressure relief valve is failing.
Any sign of water on or around your boiler is a sign of trouble.

Water does not, in and of itself, mean that your pressure relief valve is failing. While that is certainly one of the options, you could also be dealing with a faulty circulator pump or a leaking water pipe connection. Do your best to determine the source of where the water is coming from before you call a service technician as this will help them determine what parts and equipment they will need for your service call.

If the water is, in fact, coming from the pressure relief valve, you may be wondering what has caused this to happen. There are five common reasons why a pressure relief valve will release water. One of the most common reasons is that the valve is either defective or old. Another cause has to do with the expansion tank in your system. If the expansion tank goes bad it can raise pressure in your system to the point where your pressure relief valve must release some of the pressure.

Other pressure related causes include too much pressure because of a bad fill valve and too much pressure because of a leaking coil. Finally, if the water temperature is too high, it can create steam which will need to be released from the system. The one thing to always keep in mind is that the problem may not be a faulty pressure release valve; instead, it may be doing exactly what it is supposed to do.
