Relay? Did I miss something? Most people don't bother with relays for the
small pumps since they only draw a few amps. But if you are using a relay then
indeed a diode will solve that sneak circuit. But then you should put in an
MOV across the relay coil (or the diode) to prevent the inductive kick back
from over stressing the diode.
