What does the cold water tank in the loft feed
We’ve got a tank up in the loft and I’m trying to understand what in the house is fed from it, because some taps seem stronger than others and I can’t work out why. What does the cold water tank in the loft actually supply? How can we work this out?
Expert Trade Answers
"Your downstairs (kitchen tap) may be fed from the mains whilst the incoming main will then proceed directly up to your CWSC (water tank) this then will feed other outlets such as your bathroom. Depending on your system within your house you may also have an F&E tank as well up there."

"Hi.
If you will isolate the main water supply and step by step run your water taps for a couple of minutes each, you will see which one is tank fed. The main can run only a couple of seconds (leftovers from pipe).
Usually the kitchen tap is main feed and the rest is tank fed."
