Airlift outlet depth

Post by slk » 11 May 2019, 20:42

In my new project I am going to use 4-6 pressure airlifts. Main problem is I have to put horizontal pipes to the pond below grass level. My pond is also elevated about 30cm above ground level. I plan to put those pipes (airlift outputs) 60cm below water level. I am going to use double T of course. Will it work, 60cm below water level?

I think that it should be no problem to put out air via double T (also 60cm tall, to be above water level). What do you think?

Hello,

That's an interesting setup, thank you for the drawing.
I believe it will work, I can't say anything about the efficiency though.
I will ask Marc to have a look at your design.

I have decided to move airlifts output 20 cm up, so now it looks like this

Is there any limiting factor as to why the pipes cannot be above the ground?

I agree, it would be much more efficient if the outlet was at or just below the water level.

Pipes can not be above ground level, cose I have got lawn there. I have to burry them a least 10 cm under the grass level.
