FAQ
Hose vs water truck? +
A 20,000-gal pool at 9 GPM hose = ~37 hours. A water truck moves it in a day for $400–$1500 depending on local hauler rates and distance. Worth it on big builds.
Watch out for slow fill on plaster pools? +
Yes — most plaster manufacturers require continuous fill without stopping to prevent a "bathtub ring." If you can't fill continuously, plan for a water truck or multiple hoses.
What's a typical city water rate? +
$4–$10 per 1,000 gallons in most US cities. Hit your water bill or city utility site for the exact tier rate.
