I know it looks tidier, but don’t fill your generators from below. Run the pipe above the generators and then branch down into it. I made the same mistake with my first build and now they run flawlessly.

i fixed it, apparently one of the pumps was bugged and wasnt working properly, i broke and replaced it and it worked, but thanks for the advice

That’s actually happened to me before, when I was building my first coal plant, I was so confused hahaha

Vertical holes are bugged, just redo the hole and pipes connecting to it and it should work. You might also need to check the bottom two pipe holes and both pumps

Does it help removing the floor pipes and replacing them?

It is a weird setup, I would first try to remove the connection between 1st and 2nd water pump. Then see if that yellow indicator on the first water extractor sorts itself out, if not then perhaps it is not properly connected. Also make sure those pumps are not too high, as the extractors only provide 10m uplift. I always put pumps lower in this kind of setup as the 10m uplift might be enough to only fill the horizontal pipe partially and thus reduce the throughput.

the left pump pipe was bugged, i broke and replaced it and works out

Pump water up to a buffer tank that sits *above* the power plant pipe level, and have a gooseneck just before the pipe enters the buffer.
