Tapped into Mains Combi Boiler Feed and Pressure Drops
Posted: Sun Aug 23, 2015 8:40 am
Hi All, new to the forum but need a little guidance.
I have a combi mains fed boiler. Yesterday i tapped into the mains feed to the boiler to provide a water feed for an outside tap.
When I run the new tap the boiler pressure drops and I have to refill the boiler.
Have I tapped into something other than the mains feed?? Or have I simply not understood that tapping into the mains feed will drop the boiler pressure when the outside tap is used?
Thanks all
