Repair or quote in Yorkshire Dales water pump

Hi, I’m looking for some advice about how to find a reputable person to look at my motorhome water pump. I’ve discovered that it’s only intermittently getting the water to some of the taps, but tnat when the  pump is on , it’s leaking heavy from ? Pipes under the van. . 

I asked at my site but they just told me the location of the nearest place( I’m in Hawes) which was Catterick but I looked at the reviews of that place and they weren’t promising .
