Thanks Phil, I think that is exactly the problem. I have installed a valve in the fore line on Saturday to do exactly what you proposed.
However, today was spend proving that this was the problem.
We had a few solutions which included replacing the fore pump with a rotary vane pump. However, your suggestion will be given priority.
