Can I run my Coffee Machine from a tank of water and not the mains

Quick answer is yes most espresso machines do not need main pressure as they have either built in or external rotary pumps.

These will creat a pressure of around 8.5 bar for making coffee.

But be carefull - big tip is do not run the tank dry. Pumps are wet run and will jam if there is no water and or get an air lock.

Another tip is too get a one way valve on the end of the hose in the water tank, this will ensure the hose remains full [ie the water does not drain back into the tank so the pump always runs wet. Get a valve that opens easily - test by blowing through it - all you should need is a gentle blow!
