Hi, I had previously posted regarding a dead boiler and thanks to some good advice from people on here i managed to trace the problem to a knackered pump, so i checked out ( in here again) how to drain the system. BUT unfortunately i have built my decking over the top of the outside drainer valve !!! I tried to remove the planking but some of the screws have threaded making it impossible for me to get to the valve, what i would like to know is is there any way possible i can drain the system without using the outside drainer tap? OR is there any way for me to replace the water pump with the system "live" so to speak??
Hope someone can help.
