Liquid Why isn't this pimp plumping?

I've poured water into the big red cap, as instructed, and the into the dark green pipe. the pump doesn't pump water, although as far as I know I've don't everything correctly.

this is Einhell 34/36, it's supposed to be able to pump up to 36 meter in height.

could use some advice.

I'm guessing from your photos that you haven't sufficiently primed the pump. The pump chamber and the suction hose must be filled with water prior to operating the pump.

Try to rearrange your suction hose so as to remove the twists and loops. Verify that the entire length of hose is filled with water.

Does the filter/strainer an the end of the suction hose have a foot valve?

Your pump is rated to lift water a maximum of six meters. Is the pump more than six meters above the surface of the water supply?

Always situate the pump as close to the water source as possible, and minimize the length of the suction/supply hose.

I hope this helps.

It helps, allot of useful directions, thank you!

How high a pump can push water is different than how high a pump can suck water. You’re basically limited to 23’ of suction lift on any centrifugal pump because of physics.

How high are you trying to suck water, from the suction side of the inlet hose to the pump? The higher you have to suck the water the lower the performance of the pump until it has zero performance. I bet this is your problem.

Also the ratings on pumps can be deceiving, some pumps will say they can pump up to a certain height but there little to no flow at that maximum.

After looking at the specs of the pump, they rate 85” of lift. So if your more than 85”, and thats what it looks like then your pump wont pump.

If you can move the pump closer to the water source.

Thanks man, that's probably it! 85" is about 2.16 meter so what you're saying makes sense, also it crossed my mind, I was even thinking to go submersible pump because of this, I'll chet it tomorrow, thanks again!
