Intermittent Water Flow Can Anyone Help?

[instrength]

Hi All,

Anyone come across a problem with air in the system. I cannibalised my pure water trolley and used it to fit into the van with a tank. Since doing it I seem to have air in the system To be fair I didn't put the non return valve in which was attached to the hose.

Wondering if anyone else had the problem and if so how did they fix it.

Cheers...

Detach hose as near pump outlet as poss, turn up to full whack for about a minute
