Mine's above the tank (just) but I have a none-return valve fitted just before the pump inlet.

Ordered up

Is this the best place to have it fitted ? .. I take it (well they look like they do) fit inside the hose ??
 

Could it be fitted more or less immediately after the outlet tap on the tank ? As in theory the idea is to stop it returning back down the hose to the tank .. ??

I cut my hose in two & inserted the device equally into each piece then put a cable tie either side to secure- it's a nice tight fit.

It needs to be fitted as high up in the hose as possible, not low down near the tank outlet. Mine is just before an elbow turns the hose onto the pump inlet

Will It not cause the same problem of air from the valve back down to the tank outlet then if it's high up ..

It may well work at the bottom, I'm no expert, my thinking was the risk of any air getting past it when the tank is low & the water is splashing about in the tank.

In Fact, thinking about it, it might even work better at the bottom!!!

that's why I was thinking that mate .... but having not done it and knowing about these things I was taking expert advice... so that said im thinking the nearest the outlet it is.... then the less chance of the air lock as the water the other side of the non return bit ... will be going no where...

Give it a go, all I know is that mine works as I don't have to prime the pump 20 times a day anymore!!!

It can't go back down the pipe anyway if the one way valve is installed air tight.

youre right but if the valve is nearer to the pump inlet ... then it go back down the pipe between there and the tank... i.m going try it anyways ...

cheers for all the input mate
