Yes, but my pump will be 120 volt.
This will ensure I get proper pressure to my faucets.
Garden hoses and long connections tend to cause massive pressure loss.
Not all city / camp ground water connections have good pressure.
This will ensure I always have consistent pressure.
It will also keep my fresh tank full. This is good in case of water supply interruption, ect.
