Had to replace my one way return Valve. When turning on tap using on board tank water is going back in to aqua roll via the external pump. Tried turning valve round still doing the same...help
Sounds like you have a faulty valve. Water should pass through it only in one direction, so if turning it round makes no difference, water can obviously pass through it in either direction.
Qne way valves often fail as debris of some sort gets trapped in the valve mechanism preventing it from closing fully. If you can dismantle said valve you should be able to clear the offending item.
