You’re telling me I could fill a typical water tower in 1 hour with a 500 W pump running off a kitchen outlet?

500W is a lot, it is hypothetically enough to move 10 liters of water 50 meters up every second. A motor on a cycle an electric bike is 250w.

A kitchen tap provides like what, 0.2 liters per second?

So in an hour that's 36000L of water pumped up into the hypotheticals 1 million gallon tank. Right on the three orders of magnitude short that a previous commenter pointed out.
Sounds like they confused W and kW then?
Really good sanity check concept!
Calculator said 400W for 1000L/s and my mental sanity check missed the duration units and thought 400W can move a ton of water.
