I doubt the basin would be anywhere near the evesPresuming the basin in the loft is a fair bit higher than 6" off the floor then the the hot tap will be above the level of the cistern

Usually the eves are the overhang of the roof trusses/rafters that extend out over the wall of a house. Presuming the eves in this case are the spaces/rafters in behind the converted loft walls, then it would be fair to presume the floor of the converted loft is on those same rafters/joists and at the same level.I doubt the basin would be anywhere near the eves
Presuming the basin in the loft is a fair bit higher than 6" off the floor then the the hot tap will be above the level of the cistern, so probably no gravity flow, therefore the pump would have to be universal (negative head).
If so may just need the mini EV re-charged
Please post a pic of the pump.
Yes sorry, the basin is on a pedestal and is around 800 mm off of the loft floor. The bath obviously lower! Pic attached.

If that's the case and the basin is on that same loft floor either on a pedestal or vanity then that will make it at least 800mm odd off the loft floor so the hot tap on the basin will be at least 650mm above the base of the cistern if the cistern is 6" above those rafters?
I turned off the shower and then the hot taps for 5 seconds and back on and they run fine. I tried this several times at differing intervals and it seems to stop working completely after about 30 seconds following turning them off and back on again. If that makes sense?Ok you get upstairs hot tap running and shower is then turned off the hot water carries on running. If you the turn the hot tap off for 5 seconds and then turn it back on does any sort of flow dribble out
When you turned on the hot taps did the pump kick in immediately or was there a sort of opening initial flow and then the pump kicked inI turned off the shower and then the hot taps for 5 seconds and back on and they run fine.

It's a universal monsoon pump Andy - AKA - can be used in either a Negative or Positive headYou need a negitive head pump.

If it is what I think it is, then typically when the mini EV loses pressure, especially if it hasn't been used for ages, there's no longer enough pre-charge pressure to create the water movement needed to start the pump. The shower downstairs works fine as it's under positive pressure so there's enough gravity flow to activate the switch but not when it comes to the tap(s) in the loft above the CWSC, which is under negative head. It needs the EV pre-charge to hold the water under positive pressure and when the hot tap is opened the pressure creates enough flow to trip the switch.Why it worked before and not now?
