dinga Posted March 20, 2023 Share Posted March 20, 2023 My bore pump is supposed to be self priming but IT doesn't pump water unless I manually prime it (I've run it for a few minutes to give it a chance to self prime but there is no sign of either water or pressured air coming from the outlet. Fearing possible damage, I've then turned the pump off). Here's the Spec Sheet (the bore is some 22 metres deep with the water drawn from around 16 metres). https://hupshenghardware.com/product/pedrollo-jdwm1an-0-75kw-20l-min-42mh-1phase-1-1-4x1/ Once manually primed, it seems to work well with no sign of water leaks to suggest there may be an air leak. Any suggestions????? Should I just run the pump longer to see if the self prime does actually work but just needs a little more time??? Link to comment Share on other sites More sharing options...
In the jungle Posted March 20, 2023 Share Posted March 20, 2023 Assuming the pump is submerged in water it does not need to be primed. Have you checked that the pump is under water? Link to comment Share on other sites More sharing options...

Have you checked that the pump is under water? No - these are Jet Pumps - NOT submersibles Link to comment Share on other sites More sharing options...
In the jungle Posted March 20, 2023 Share Posted March 20, 2023 Sorry. I assumed you were talking about a submersible. Link to comment Share on other sites More sharing options...
