We have a holiday home on the NSW Central Coast. There are a couple of sand spears (bores) in the back yard and we have 2 old Billabong piston pumps running off these to water the lawns. They have run reliably for the 8 years we have owned the place - and probably for many years beforehand - until recently when one stopped pumping water.
The first thing I did was check the valves and the operation of the piston. All seems to be normal - though I'm no expert.
So I figured I would just prime the pump and get it going - then see if any problem materialised.
So I removed the priming plug on the pump itself, stuck a hose down it, filled it up with water, started the pump - but no result. I did this numerous times - no result. If I left the hose running in the priming hole while running the pump then the pressure in the receiving cylinder slowly built up, but it still didnt work on its own.
So I think I'm doing something wrong with my priming.
Should I be trying to fill the sand spear up with water first ? I think the pipe down to the water table is now partly or fully dry, and when I put water in then the non-return valve at the top of the spear is preventing any water from flowing down into it. Furthermore, I cant really imagine the pump has enough suction to fill the pipe on its own, drawing water all the way up from the water table. So maybe the pipe down to the water table is acting like one huge air-lock ?
So can someone give me some guidance on the correct way to prime a pump ?
Google is not helping.
cheers and thanks

I have attached a couple of photos:
one shows the pump as it sits now. There is a short pipe through the wall of the garage, then a 90 downturn to the sand spear (second image). At the top of the spear you can see a bulge - that's the non-return valve.

How do I prime this bore pump
