I live in a low mains water pressure area, so I had to install an Aquabox water tank in my garage which has a Genyo controller and submersed pump.
It's 3 years old now, but I've only recently noticed that the pump is cycling approx. every minute, even when there is no water being used, is this normal?
I assumed it's not, below is a list of things I have checked:
- I've turned off all our toilets in case there's any of them running
- The underground MDPE pipes are all sound (recently dug up and replaced and issue was occuring before)
- The tank is being filled and there's no failures reported on the Genyo controller
- I've pressed the valve on the expansion vessel located in the house and it releases air and not water, so doesn't appear to be damaged.
There are no obvious signs leaks in the system, so I'm stumped at this stage and any help would be appreciated.

Regardless of the state of the tank, it should not cycle at all with no water being used. You have a leak, probably a leaky check valve (so water goes back to the pump tank) if you are QUITE certain no water is being used. That's typically built into the pump outlet for a submersible pump.
If not, then you have something leaking and using water you're unaware of - water softeners and toilets being my prime suspects, as they don't tend to leak in such a way that you find a puddle to notice the leak. But you already tried the toilets. If you have a valve you can shut all water off with after the pressure tank ("expansion vessel"), try it, and see if the problem remains.
Air pressure in the tank should be 2-3 PSI below pump cut-in with the water side drained (incoming water & pump shut off, no pressure in the water pipes.) But the tank isn't the main problem if no water is being used and the pump is cycling.
