If you live in a town that has good water pressure and you are using your hose and your neighbor's hose, it should take 24 to 30 hours.
If you use a garden hose, about 1 to 1.5 hours
Around 3 days depending on water pressure.
It would take approximately 9 hours, 22 minutes, and 30 seconds to fill a 15,000 gallon pool with a garden house that blasts out 1,600 gallons an hour. But that does not take into account chemical levels. In order to have a safe pool, free of infection-causing bacteria, you would need to adjust the pH level and total alkaline level of your pool.
with a hose
There are 4 quarts in 1 gallon. So you would need 4 quarts of water to fill a gallon.
A day or 2 depending on the water pressure
If you live in a town that has good water pressure and you are using your hose and your neighbor's hose, it should take 24 to 30 hours.
With a standard garden hose, about 24 hours
If you use a garden hose, about 1 to 1.5 hours
The time to fill a 12000 gallon pool depends on the flow rate of the water source. For example, if the flow rate is 10 gallons per minute, it would take 1200 minutes or 20 hours to fill the pool.
Around 3 days depending on water pressure.
That would completely depend on the flow rate from the source. There Is no standard answer to what your fill rate would be. If you calculate the mount of water coming from the hose by timing how long it takes to fill a 5 gallon bucket, then calculate the volume of the pool, you can then estimate how long the fill of the pool will take.
Assuming the buckets are identical... Hose 1 fills 1/45 per minute and hose 2 fills 1/30 per minute, so together in one minute they would fill 1/45 + 1/30 ie 5/90 or 1/18, ie the bucket would be filled in 18 minutes.
Fill a gallon bucket, timing how long it takes to do so. Then fill your hot tub using the same source... example: if you filled the bucket with a hose, then fill the tub using the same hose. Then time how long it takes to fill the tub and divide the time it takes to fill the tub by the time it takes to fill the bucket and then you know how many gallons it is.
I would suggest you obtain a PRESTONE flush and fill kit at a auto store. There is detailed directions on the package. Also pick-up a can of flush and a gallon or two of antifreeze. You will be inserting a fitting into the return hose from your heater core and hooking up a garden hose. After the flush is run thru the rad the garden hose does the work. Does a good job.
because you have the nozzle jammed too far into the tank
