for hosepipe you cant, you would need to upgrade the hose to 15mm house grade pipe to get them fitted.

that's what i used when i built my system, fitted non return valves to both my pumps and not had a airlock in the system. even when i empty my tank fully, drive about then refill it,

I've got one on my tank, go to eBay and type in caravan 1/2 non return valve it will fit straight in garden hose pipe.

Would you mind linking to the eBay item as there are loads of different ones? Where have you fitted yours?

But I had forgot about it and it's still in the cupboard........... ::)roll

As close to the tank outlet as you can.

So that's between the tank and the pump?

Yes, it will prevent water from returning back to the tank when driving etc.
So the valve should be fitted close to the tank outlet and before the pump.
That's how it's supposed to work in theory, but I've yet to fit mine.
