Carefully remove the impeller and take a look at both seal faces, if there are any scratches, chips or uneven wearing then you should replace the seal. If after you clean out the impeller the seal faces look good take a Q-tip soaked in a bit of rubbing alcohol and clean the seal faces before replacing the impeller. Even if all looked good the seal may still leak as they don't always mate up perfectly if they've been used for a while. You may be able to buy the mechanical seal at a pump rebuilding company for about $20 rather than ordering an actual reeflo seal if that is any easier for you.
