Python has no suction

Hi guys,
I started using a Python recently and I don't seem to be having much luck with suction. The first time I used it, the suction was very weak, enough to slowly change and fill the water, but not strong enough to pick anything up from the substrate. The last time I used it, it pretty much had no suction at all. I could use it to fill the tank back up, but even that was pretty slow. This isn't a DIY, it's an actual Python I got as a gift. My husband even totally replaced our faucet to one that was compatible. I've tried the obvious, checking tightness of connections, etc. What in the world am I doing wrong? Thanks for your help.

You probably need to turn the faucet up more.
If it has little suction and fills slowly, that is likely the cause.

You say you checked the connections, but did you check the tube itself to see if the connection is tight with the hose? I recently got a replacement tube that was faulty - air was getting sucked in through gaps in the tube.

Other things that will effect the suction levels are distance between tank and sink, height of sink in comparison to tank and the water supply pressure (shared supply etc)

Hope this helps.

That's the first thing I thought of too. I tried that but it didn't help at all. Unless my water pressure just isn't strong enough overall? But I had the faucet turned up as hard as it would go.

I'll go back and check the hose, maybe when we initially put it together we did something wrong. Thanks.

The sink and tank are actually pretty close to each other, would it help if I cut the hose to shorten it? Height of sink is about the same as the tank. My water pressure isn't super strong out of that sink, but fine everywhere else throughout the house. Maybe the new faucet we put in doesn't allow for pressure strong enough to promote suction? If we have to get another new faucet my husband may refuse, lol.

What is "Python"? I have been hydraulic engineer. Is it an injector pump?
Water flowing past the throat and sucks another water with?
Please, explain to me the concept!

Yeah, I got it. There is an injector. Thank You.
How well they sucks, depends on the speed of the flow and by the constriction at the venturi tube.
Is not it a loss about the many water flowing past?
