Stick a non return valve between tank and pump

Same here...I turn the pump off when changing barrels but still get 2 or 3 minutes of low pressure before it spits the air out...annoying.

Can't you install your pump in one of those vacuum boxes Gardiners are selling lately, they prevent air-locks being that there's no air present you can't actually get an air-lock.

Make sure that any connections between your tank/barrel are completely airtight and If you have half inch hose between your barrels and your pump switch it for minibore (8mm ID). All that extra unnecessary volume in the hose causes a problem when you get air in it.
Once I did this my pump clears airlocks in about 2 seconds flat. You also need to disconnect the hose from the output side of the pump whilst clearing the airlock so there is no hindrance form back pressure. On my trolley I've made this easy by cutting the hose about six inches away from the end nearest the trolley and inserting a JG connector in the hose. Others have done it by not using a waterstop connector on the trolley and disconnecting there.
I empty most of my barrels everyday and airlocks are never a problem with this setup

When priming the pump (clearing an airlock) you want as little back pressure as possible. The way to achieve this is to disconnect the hose on the output side and as close as possible to the pump.

I have fitted some old microbore between my pump and my reel, in place of  13mm tricoflex
Flow is great and eventually got rid of the air locks
Cheers for the help lads
That's what this forum is for eh!!!

Place your pump(s) as low down to your van floor as possible.
