Hi,
An axial foot check valve is installed in the vertical position in a sump.
The height difference between the (pump suction flange) and the (foot valve location) is 3m.
The issue is that the foot valve is leaking (not fully closing)to allow to prime the pump and hence it is not possible to pump water from the sump.
The manufacturer manual of the axial check valve states that 5m WC is required for tight closure of the axial check valve in vertical position.
Can we install the foot valve horizontally using a 90 degree bend, so as to make the same axial valve work as a foot valve (with tight closure)?
Do you see any other way to make the scheme work without changing the foot valve?
Thanks
