No Boiler Pressure
There are few times when your boiler will fail and lose its operating pressure, but there is always a chance that it may happen. However it does sometime happen. The best way to deal with this problem would be to call a professional service like Earls Court Plumbers who are skilled tradesmen. If you are confident then you can attempt to rectify this, firstly by taking a look at the pressure gauge fitted to the boiler, this is a good start.The loss of boiler pressure can be the result of a couple of things:1). A leak has developed in the system.2). Failure of an expansion vessel.An Earls Court Plumber is a fully qualified tradesman. Maintaining a constant pressure is crucial and in the majority of newer combination boilers this is achieved using cold water flowing through a mechanism known as the filling loop. Your heating system is able to reinstate its pressure via the loop. The makers manual will let you know if you yourself can perform this action on your boiler. Assuming that the problem is found and resolved, follow the steps below:Manual Pressurisation:A). To manually re-pressurise, firstly locate the filling loop and the pressure gauge, and ensure that the gauge can be monitored while accessing the filling loop (the system pressure for most sealed systems is 1.5bar). The loop is a silver flexible tube fitted with a lever at each end, in the off position the levers will be at 90 degrees to the pipe. Move them slowly so they both sit in line with the pipe. The water should now flow.B). Monitor the pressure gauge and it should slowly rise to a green sector of the gauge or a marked 1.5 bar pressure. Once this is achieved, then turn both levers back off. You can over pressure the system, so monitor the gauge constantly, If this is action does not work, then call a professional.
