I would take that spring check valve out and try running it
If it works with out it, i would put it back on the outlet side of the pump
Dave,
That vertical pipe is on the outlet side of the pump and the check valve is on the inlet.
Gordy if this is set up the same way as ours then it is drawing watre out of the filter then which ill be primed from the water in the filter , there is no need for a vertical pipe but I still have a feeling its close proximityto the inline pump is causesing it to draw air valve or no valve.
Apart from the vertical pipe the UV-C needs to be further away from the pump
thats all .

That pump is an impeller (rotary vane) pump .
Such pumps are all "in-line" pumps and the inlet will always be on the front of the impeller housing (in line with the motor axis) where it sucks the water into the impeller. The rotary vanes of the impeller then throw the water outwards through a channelized duct to the outlet on the top of the impeller housing via centrifugal force. So the pump cannot suck air in through that pipe, it is pushing water out through it.
It looks very much like a Simer brand or a Simer build for a pond supply company under that pond supply companies name.

Our inline pump is fed by water from the filter water has weight behind it as we all know so its going to seek the path of least resistence which is the exit ing pipe from the filter.
The inline pump then pumps the water through it , past the UV-C and out into the pond
Itf this filter is set up the same way as ours then water is drawn out of the pond, up then into the filter then down through its bottom up into the next filter then down through its bottom up to the next etc etc
An inline pump we refare to as dry pumps because they channel the water through them and dont sit on the bottom of of the pond
