A Plumber shows how to connect a filling-inlet combination to a central heating boiler This makes filling the CV installation very easy. You no longer have to fill with a filling hose. All you have to do is open the handle of the tap and the central heating will start filling. Many people have problems filling the central heating system. Often it will leak and or you will not get the hose coupling on properly, causing it to leak. This way everyone can fill their central heating system without any problems. #plumbing #plumbingtips #plumbingrepair #plumbingdiy #plumbingtools #plumbingbasics #howtodoplumbing #howtofixplumbing #plumbingtrick #loodgieteranouar #loodgietersvantiktok #inlaatcombinatie #cvvullen #diyproject #doehetzelf #livehack
