Worcester Bosch Internal Filling Key To Repressurise Combi Boiler

Product Information

Put simply, re-pressurising your boiler means allowing more water to enter the system. And while other combi boilers use a filling loop to do this, some Worcester Bosch boilers use an internal filling key. You can do this via a drain-off valve. A drain-off valve can be on the boiler, a radiator valve or anywhere on the central heating pipework.

Open both of your filling valves using their handles (you may need to use a screwdriver) to allow cold water to flood your system We are proud of the quality of our refurbished parts and they come with 12 months replacement warranty. Your receipt will be the proof of warranty and please keep them somewhere safe. If the bag is dry after your Worcester boiler loses pressure you must have a leak on the central heating system which will need to be found and fixed. The loop valve will be on and allow water through it when it lines up with the hose of the filling loop. When it is in the off position and doesn’t allow water through it, it will be perpendicular to the filling loop, creating a kind of t-shape. You should never look inside your boiler, only a Gas Safe engineer should do this. Why would you need to repressurise a boiler?

And if you do or do not find a leak, book an engineer and we’ll be on hand to help. Unfortunately, some idiot at Worcester Bosch thought it would be a good idea to use a key to repressurise their boilers. Low pressure will mean that your water won’t run as effectively as it should, meaning that you will be paying your heating bills for a certain standard of running efficiency that you aren’t getting. High boiler pressure could end up damaging your boiler and its system as it won’t be used to the high pressure that it is currently running at.
