None, if the tap is turned off!
It depends on the pressure!
The standard garden hose thread size for most common garden hoses is 3/4 inch.
The typical size thread used for connecting a garden hose is 3/4 inch.
A garden hose typically has a water pressure of around 40-60 pounds per square inch (psi).
The water flow of a garden hose typically ranges from 5 to 10 gallons per minute (gpm), depending on factors such as the hose diameter, water pressure, and any attachments used. A standard 5/8-inch diameter hose at a typical water pressure of 40-60 psi can deliver around 8-10 gpm. However, smaller hoses or those with lower pressure may have reduced flow rates. Always check the specifications of your specific hose for the most accurate information.
The standard garden hose size fitting for most outdoor faucets is 3/4 inch.
The standard garden hose connector size for most outdoor water faucets is 3/4 inch.
The standard garden hose thread size for most outdoor faucets and attachments is 3/4 inch.
Crankcase breather hose.
The flow rate of water through a 1-inch hose line can vary based on factors such as pressure and hose length. However, under typical conditions, a 1-inch hose can deliver approximately 320 gallons per minute (GPM) at 60 PSI. This can change with different pressures and hose types, so it's essential to consider specific circumstances for precise calculations.
approx. about 10-11 hours. On a above ground pool
i believe the pressure does not change but the volume of water you will be able to use will be less
