<p>Actually best of all: you don't have to run low voltage DC
circuits to the pump room. Another thing about the ECM drive
pumps, they have much higher flow rates available than the El
Cids. And if you're worried about your old school street cred in
the off grid world, they are still technically DC at the drive,
for those old timers that insist on DC.<br>
