I have just bought a Ace Ambassador and connected the water supply. I have switched on the pump. After a few seconds I getting some water in the kitchen sink and decent pressure at the bathroom sink. However there is a lot of water pumping out of a pipe that is at the back of the input manifold.
If I was guessing this would be a return or overflow pipe. But to be honest I have no idea. Can some one help or point me in the right direction of a manual on the internet. Thanks.
