And you connected the hose from the tap to the top manifold and not to the bottom, as shown?, (incorrectly IMO, if the flow meters are installed, as they might act as non return valves when the water tries to flow upwards through them?)
If you refer to my previous photo you will see that the flow meters (where i attach the tap hose) are at the top, and return vaves are at the bottom, which is where I am attaching the drain hose.
I am off for a Christmas drink now - will post to any relies tomorrow.
