I recently got a March Pump and have the following suggestions for people using them:
1. put it on a GFCI circuit and make a housing that protects it from possible errant water spray
2. orient it so that is inlet faces up, this minimizes air pockets
3. use a Tee to conect a dump valve to the inlet for priming
4. use a ball valve on the outlet for controlling flow
5. use male quick-disconnects on all the brewing hardware, with female QDs on the hoses.
