My guess is because you've got 230M of 22mm pipe. Huge amount of friction in the pipe reduces both flow and pressure?

What type of equipment have we attached to that gravity system cause ceramic disc cartridges have a poor flow rate compared to a rubber washer.
Another issues is modern equipment doesn’t like imbalances between the hot and cold supplies.

my guess is, you're outlet is rising thus, the head of water is reduced,  |

That 200m of horizontal pipework will put a brake on the flow rate whilst that (10m?) upstand will reduce the pressure/head of the 22mm pipe so it's a double whammy!
That's my thinking on it.

I reckon it’s summat to do with air pressure. The air pressure at 30m height is obviously only slightly less that it is at ground level. Plus the fact that the 22mm pipe is totally inadequate for a water tank that size. 😉😉😉😉😉 😂😂😂😂😂😂
On second thoughts, it’s mainly due to the 200m length of 22mm pipe. 😉😉

Yup, that’s pretty much it CF. There’s too much resistance on the narrow bore pipe, it’s killing the flow rate. The working pressure will change slightly with reduction of head, but the pipe bore will not greatly affect the pressure. The flow of electricity is the same, you have big fuck off wires to carry higher Amps. Look at the battery leads on your van, the biggest wires are at the battery. The battery may only be 12-14vdc, but you need to pull a high Amperage of Leccy to turn over the engine, to start the van. The analogy of water flow & Leccy flow is used all the time. |

You compress air to give you a greater pressure. Yeah, you got it, the length of the narrow bore pipe is too much resistance & kills the flow rate. |

I can remember something from my time at college that's little known in the trade. It concerns the hight the expansion pipe over the tank, I'll keep stum on it for now just in case it's on Dicks fag packet friday list!  |
