12-volt power for macerator pump
Our newly purchased macerator pump requires 20-amp, 12-volt power. Have you found a simple way to supply that power to the pump? I'd like something that would plug into our 120-volt house power.

Works great.
A 12 volt dc 20 amp power supply that would plug into household 120 volt ac would be a pretty expensive and heavy duty unit. The best way is to run fairly heavy duty wire (about 10 AWG) directly from your batteries to operate the pump.
