Jay see 1997 GU build up

The diaphragm pump has a poor suction capability, which is why they only rate the discharge head. You will do better lowering the inlet of the pump to the same level as the tank outlet, then it should work fine.

Thanks.

I did try it at a lower level, but probably not long enough to get the air out. It was late and I was getting impatient I will give it another go on the weekend. The bloody shopping trolley is playing funny buggers, just out of the blue it gets irregular revs then stops, starts up fine and keeps going. Did it twice this morning within 15k out of a 45k trip. Ahhh,
