i have a 50ltre purefreedom trolley its been in the garage for 6 months  i have put a new controller and battery and pump on it i got it working great   but now its not

when i pull the hose to stop the water with the univalve   its stops traight away  but when i turn it on its spluts a gust of air out then the water then starts flowing slowly then almost stops , i can see the airlock   but why is it doing this i have bled it loads of times  soon as i connect the pole switch on airlocks
should i disconnect the pressure switch on the diaphram  pump  and by pass it

iam using gardiner fan jets  theres no problem with the van mount just the damm trolley     

any advice  i usually use the gardiner backpack but i need to  use the 50lte trolley   why is it airlocking


advice please

I have sorted it mate. It's been  that long since I used it I wasn't bleeding the pipe properly and I was getting airlock.

Took me 2 hours to realise   I took the trolley to bits and out it back together

Then realized   bleed pipe
