Maybe there was some air trapped in thr pump? I'll have it![]()
I have been trying to get all the air out of this small loop its running now and even though its just the pump, 2 fitting and a metre of tube I just cannot get the air out. what a crap design.
if we both ever get to 1000 posts you can have it on MM! for nowt more than the postage if im not using it by then
