when you use the water hose, how come...?

Question

when you roll it back up..it spews water?
And how does the water come out so fast when you turn it back on? Does the water just stay stored throughout the hose?

Answer 1

I learned this from watering horses in the winter. The water stays at wherever the lowest point is (cause of gravity). There will always be water in a hose when you turn it off--it won't magically go away or go back (up) into the spigot.

To empty it (which you should do if it's freezing cold outside, or if you don't want a surprise of water pouring out on you as you wind the hose), lift the hose as close to the spigot as you can, then go the length of the hose lifting the entire length of the hose until you get to the end.

Ideally you will see water pouring out of the end of the hose as you do this. If you do it right the hose will be almost completely empty, and should not spray on you as you wind it.

Answer 2

Yes the water that first comes out of the hose after you turn it on, is actually water that was still in the hose after the last time you used it. This water actually has become stale, so let the water run for a bit before you use it. When storing the hose for the winter, start at one end and roll it up, as you do this all of the water left in the hose from your last watering, this will actually make sure that the hose is empty, and ready for storing.

Answer 3

There is a small amount of water which stays in the hose, while it is connected. If you are storing a hose, it should be drained as much as possible. Fire departments in some cities, actually hang the hoses, from one end, so that they may drain, before storing. This prevents rotting.

Answer 4

Yes, water stays in the hose until you turn it on again.

When you coil it up, you're applying pressure and pumping some of the water out.

Answer 5

some does and some doesn't. Depends how long the hose is
