Citroen C5 rear suspension sinking when left for 1/2 hour

Car: Citroen C5
Variant: Exclusive tourer
Model Year: 2011
Categories: Steering, Suspension, Brakes, Wheels & Tyres
The rear suspension starts to sink after about ten minutes of being parked but when engine starts up the rear rises to proper height within a few minutes.
Is this a non return valve in the pump and can it be repaired?

I believe you are correct and the non return valve is in the pump but cant say for certain as I tended to avoid doing susp work on Citroens and left to a friend who was a Citroen specialist and usually scanned with Lexia for fault codes first if nothing obvious
