Access to domestic water pump, Orian Gemini

Hi all,
I'm new to this forum having only picked the van up at the end of August.
Anyway, all well so far other than the water pump is annoyingly noisy, it sounds like it is loose on its mountings.  I imagine that it is located in the closed space beneath the wardrobe, behind the heater and presumably close to the freshwater tank.
Are any of you able to let me know how to gain access?

Many thanks!

I think the Orion Gemini is basically the same model as our Pollensa. In ours the pump is under the wardrobe floor. You will need to remove the two brackets that hold the table in place when stored (if yours has these, the Orion may store the table elsewhere). We had to remove the door latch plate from the rail across the front of the wardrobe.  The wardrobe floor is supposed to be held in by several screw things (not sure what the right name is), hidden under brown coloured plastic covers, they turn 1/4 turn to release (a bit like Ikea furniture, if that helps). On ours the panel just lifted out with a bit of jiggling.  Once the wardrobe floor is out of the way the pump should be obvious, sitting on a strip of wood that runs across above the hot water tank. The Shurflow pump is mounted on rubber feet to minimise noise and vibration, and if the mounting screws have been over tightened the damping doesn't work, so this is worth checking. Our pump isn't quiet, but it's not intrusively noisy. Worth checking there aren't any air locks or other probs. with the system in case it's pumping air.  NB if you take the pump out take pics. and make a note of the various wires first as it's easy to muddle them up!

Many thanks Slow-Lane and Dave 418 that's useful information, gives me a bit more confidence to go and explore.
