We all get to a point in our lives where we wish we had the ability to predict the future. And when you are suddenly faced with some sort of damage in your home such as a boiler leak, this desire becomes even bigger. Getting a home inspection will really help you to prevent these kinds of incidents. But what if we tell you there is a way to tell the future and become a boiler condensate pipe guru who can detect possible damages even before they occur! Lawrenceville Home Inspection is just right for you!


Moreover, here are some common reasons why condensate pipe leaks:


Common Reasons for a Condensate Pipe Leaking


A frozen condensate pipe is the Lord of headaches, but there are some other unexpected problems that can occur. Some of you may have already faced them, others still haven’t. Whatever the case is, you will find the information laid out here highly useful.  


  1. The heat exchanger of your boiler is broken

The condensate trap and pipe come straight out of the heat exchanger, which means that if it cracks or pinholes, it will cause the system or mains water to drain into the condensate pipe. What may lead to the condensate pipe leaking is if the hot water causes the pipe joints to fail somehow. 


  1. The condensate pipe joints leak

 This can happen if the condensate pipe installation was not done correctly, like if:  The joints are not properly sealed: no PVC pipe cement was used for that purpose. The incorrect pipe and fittings are used: the only pipes which can be used to drain the condensate are PVC or ABS. As we already mentioned, any other metal pipe would corrode. If the fittings have metal content (like grab-ring), they will erode as well. 


  1. The boiler condensate trap is blocked

The purpose of the condensate trap is to gather the condensate produced by the boiler and discharge it afterwards. You might be detecting an upcoming blockage if you start hearing a gurgling noise from the boiler. In order to double-check, you can go outside and see if the flue makes strange noises as well. It is very possible that the boiler will go to ignition lockout on its next attempt to light the burner.


Because of what reasons you can end up with a blocked condensate trap?With time, debris can start to deposit in the condensate trap. Tiny bits from the heat exchanger may be corroded and can end up in the sump and eventually in the condensate trap. This, in turn, will stop the flow of condensate, which will go back up into the bottom of the heat exchanger afterwards. And this is how you get a blocked condensate trap! 




  1. The boiler condensate pipe is blocked


The condensate has frozen inside the pipe, which leads to a blockage and therefore you get a leakage upstream. You can simply solve this problem by pouring warm water onto the pipe. After that, inspect it carefully, along with the fittings, because they might split if frozen. Make sure you have proper condensate pipe insulation, so you can avoid this issue happening again.


If your condensate pipe installation is internal it could be checked by pouring water down it to see if it is flowing where it terminates. However, if the condensate pipe terminates directly into a soil pipe or soakaway, it might be difficult to inspect the end of the pipe. In this case, you will need a heating engineer and ultimately a plumber to solve this problem. 


Fixing something that is already broken and causing problems is difficult. So as much as possible, make it a habit in checking your house from time to time. You’ll never know that can help you save future money and prevent future damages to your home.
