average home has a flow of 500 gallons per hour (600 hrs), if you really want to know then fill a five gallon bucket and time it then do the math

Heres a better solution:
- Call you local water department and ask how much the rate is have a hydrant tap put on. All cities will let you tap into the hydrant with their meter. Then you rent some 4″ hose from a rental store and can have that thing full in a matter of a few hours. Then you return the hoses and call the city and the bill you for the water used. It usually if pretty affordable and is cheaper than what you reg. water bill would be (if you have one).

By the way, line size has nothing to do with gph. I have built water features with 5000 gph flowing through 1/2 line. It is the pressure that is the key.

I would talk to you local Fire Dept and see if you can tap into a Fire Hydrant and it will not take nearly as long. Plus it would probley cost allot less than doing it with your water meter. and you will be able to swim sooner than 40 + days.

A 1/2″ line puts out about 5 gpm or 300 gph. That means about 1000 hours to fill the pool which equals 41 days 16 hours.

this would be pretty simple to figure out, and may only take you a few minutes.
step one: find yourself a five gallon bucket, or any other container that has its capacity written on the side of it. Probably want something bigger than one gallon.
step two:turn on your water hose all the way
step three:time how long it takes to fill your container
step four:divide 300,000 by how many gallons your container is
step five:multiply this number by the amount of time it took to fill your container. this will give you the amount of time it would take to fill a 300,000 gallon pool with that water hose.

( this will come real close to giving you an exact amount of time, but will not be 100% accurate because of fluxuations in city water pressure, especially because it will probably take a long time to fill, and water pressure is surely going to rise and fall somewhat during that amount of time. Also, I don’t know if you are on a water meter, but if you are……wow!

Your water hose probably flows about 5 gallons per minute. Assuming that flow is constant then it would take 60,000 minutes or 1,000 hours or 41.67 days.

It depends how much flow you get out of your garden hose…once you know the volume coming out you are golden
