Are you new to caravaning or old hands and just changed c/van.?
I've worked on two C2's in each of my past c/vans when the pumps packed up.
As describing the repair/replacement of pump takes up many lines you best email me [your number 7 of those i've helped, regarding the pump, with this problem]
robertwhiting76@hotmail.com
I'll send drawings and will write instruction on repairing /renewing the electric pump on the C2.
plus a parts list.
