Hey,

In the Source, you can make the Inject or Surface Force have negative power/velocity - this way the Source would suck in the fluid instead of blasting it out.

You would need to increase your conservation quality if the fluid is far from the source, or if the distance is too great, you could also use a path follow helper to help guide the fluid towards the source.

There is one alternative to a negative source - you could use a Body Force with negative strength, but the difference is that the negative source would destroy the fluid, while the negative body force would just gather more and more fluid inside it.

Cheers!
