In January 2013 I ordered impellers for my Cummins Shurwood water pump. The wrong impeller was sent, which I immediatly returned to have it replaced....After 6 months of sending emails to follow up, I have NOT had one reply, no one answers the phone.. So my money is spent!..I have returned the wrong part in good faith, but NOTHING in reply..Terrible, Terrible service hiding behind a 'can do' web site..BE WARE Keep the H**l away from these Shonks!
