07 Duetto water pump

My water pump is leaking, I think it’s either behind the fridge or behind the cupboards under the sink.  Does anyone know it’s location and the best route to access it please?

If behind fridge, can you get access through the external vents? If in under-sink cupboard, the its either under false floor or false back panel (screws may be hidden under adhesive covers.)

On our 2003 Duetto access to the pump was from outside after removing the lower fridge vent. I had to replace our Shurflo pump, and I also added using a T-piece a Whale surge damper, which I recommend, it stopped the frequent short bursts of pump activity and smoothed the water flow particularly at low flows.
It helps to have a kitchen stool of the appropriate height when working on the pump to save your back. It will then be just your arms that ache and get scraped.

Thank you very much.  That's very helpful.

Thanks for the responses, I’ve taken the fridge panel off and found it’s the strainer body cracked so I’ve just ordered a new one.

Thanks for the update with a cure to your problem

Our Duetto was an older model with the water pump fitted under the cooker against the outer skin of the van. During a trip out at Easter our water system froze. After that the water pump was erratic and started running at odd times including during the night. 
Being were it was fitted it was hard to see but like yours the filter housing on ours was cracked probably with it being frozen. To prevent the same problem I took the pump out and improved the insulation whilst changing the filter housing.
