In response to another thread.

Could you explain why as well.

I have mine as low as possible to stop air getting in.

[Sir Squeaky]

Mine's higher than the tank.

Maybe that's why it's always annoyed me.

After nearly every move of the van I have to unplug it from the hosereel and run it to get the air out.
Otherwise I get hardly any flow and have to have the varistream high and flatten my battery.

I get fed up of having to get air out 10 times a day.

This might sound obvious, but:

Why don't you move it? :

You're asking Squeaky remember 

[tomy jackson]

mines a buth tank as its convent for me no air locks  i dident vote as its not hier to pevent damage

[Jeff Brimble]

Best place if you want volume of flow is below the tank but most are self priming and will suck 3ft.
How long is the hose you want to use ?

Nowhere else easy to put it.

Besides, not sure that's what's causing it.
You can see the bubbles before the tank, so air is building up in the tank all the time.

Is the tank vented.

[Sir Squeaky]

It hasn't got any holes no.
The water would run out.

It helps if you can keep the tank vented. (Bet you wish you had a quality camera like mine Squeaky

I've just been out and lowered my pump after reading this. Had loads of air locks today when my tank dropped below half way. Maybe my system gulps air when I brake hard. Runs fine 'till mid day then my problems start.

Oh right.
Yeah it's got a red plastic vent in the lid.

IMHO I recon you have an air leak somewhere, and they do not always leak water  as some people like to think, when the suck happens it can let small air in when it stops small air hole gone no leak, have fun finding it, I would first tighen every clip

Pumps always go on the lowest point, like Squeeky's example pointed out, it's airlock galore otherwise.

Name one supplier that doesn't have them at the lowest point in their systems. Says enough.

Another thing that helps is to keep the vacuum side to tank outlet as short as possible. And get a ball valve as a tank outlet. If you are running low on water, turn the stop in between jobs when driving, to prevent air from entering. This is number one cause of airlocks. Make sure to open it again when you stop though! 

Pumps suck about 3ft, but if that's filled with air, your going to have trouble.

If air does enter, unplug hosereel, put pump at highest setting, and let the air come out. Then connect hosereel and run like normal.

That's not even worthy to be called a system. 

(Nearly got me there. (just kidding))

Seriously though, the higher the pump, the more likely it is you will get problems.

In the bedroom lol.

Ah, I reckon it's about 4ft from my outlet to my pump, and a 2ft rise too.

When I've tidied it a bit I'll take a picture.
