In practice, any real pump will waste some power every time it is started, for instance due to moving parts that will need to be brought up to speed (and their kinetic energy is not recovered when the pump stops). Also, frequent starting and stopping will generally wear down the pump itself faster, too. | |

This can allow the water to go a bit stank and start growing things, which could clog the pump. I'd add a dose of bleach or similar to the initial bucket, which will dilute over time but help reduce any algae etc. | |

In practice that may not be the case: if it's pumping the water to somewhere lower than the source, it just has to overcome gravity to get the first water over the side of the bucket, then the water will flow more or less by itself (and the pump motor won't have to work hard at all). So it can be advantageous to do fewer, bigger emptying cycles. | |
| Nov 15, 2021 at 14:49 | comment | added | Moshe Katz | "... minimize the pump run frequency" - if the pump has a near-constant flow rate, why does the frequency matter? It's going to run for the same amount of time to push a particular volume of water, so how much difference does it make whether it runs continuously for 4 gallons or in four 1-gallon increments? | |
