Ours is pressurised, a bit of a wing and a prayer though as the incoming pressure is 0.8bar, if I'm lucky it may reach 1bar during the night. Fortunately the system holds water very well and it's well over two years before its dropping to 0.6bar. Topping up the pressure takes an age and I now have made up a home made filling device with a reservoir tank of water and a tyre valve to attach a footpump to do it. I'll be waiting till the pressure drops before I test it though!
