1/2" or 5/8" garden hose trivia

[s10crazy]

A few months ago my neighbor and I got into a discussion over garden hose and I'd like to know what your thoughts are.

Here it is......

I was filling my pool with my standard 1/2" garden hose and my neighbor came over and offered his 5/8" hose and said it would fill faster.

What are your thoughts on this? would his fill the pool faster? why?

have to get back with ya on that one,

Yup Plop nailed that one. The 5/8 would let more water flow, but at a slightly slower rate. The water pressure will not increase because the hose is bigger. The water pressure your tank puts out will always stay the same no matter what size you add on. So the bigger the hose the slower the water will pour out. The small the hose the faster it will seem to shoot out. But your pool will fill right about the same time the 5/8 would fill it. Not enough to make a difference.  Just stay with the hose you got and just let it fill.

Of course his would fill the pool faster. Save on your total water bill too (if you have one). 




Now if his garden hose wasn't hooked up to his house, then meh

[s10crazy]

I would say it would be about the same either way.

smaller would be more pressure and shoot it out faster and the bigger one would put more out but a little slower.

My thoughts exactly.......pressure would change. Not volume

Nice thinking!!

the question is dependant upon the pumps GPM rating (gallons per minute)

a larger I.D. (5/8) will flow more volume (thats more water) therefore filling the pool faster, however, that is totally dependant
upon whether or not the pump can maintain that rate of volume.

a smaller I.D. (1/2") hose will flow less volume, but capable of higher pressure.

in other words.. it will take ____ gallons to fill the pool to capacity.
the pump is capable of ___ gallons per minute max output thru say a 1" hole.
reduce the size of the hole, you reduce the volume the pump is able to push (this creates pressure)
the smaller the hole, the less volume.

simple test to prove the theory.
2 liter bottle full of water. (this is your GPM)
unscrew the cap and turn it upside down (this is the 1/2" hose) and squeeze the water out
now take the same bottle, refill it and cut the top of the bottle off and increase the size of the hole (this is the 5/8" hose)
and squeeze the water out.  which one empties faster???

I understand what your saying but it this case the pump is the city regulated water supply. lets just say it is regulated at 2 gallons per minute. It doesnt matter what size hose you put on the end.........its still only going to pump 2 gallons per minute.

It also depends on the water spicot the hose is hooked up to, it will also only let so much volume through no matter what size the pump or what the Rate of flow into the house "supply line" from city is

you would be correct on that.  so much for my theory.

The spicket is the first place to look.  If it is no larger than the smaller diameter, then it will not matter.

Pressure is pressure and volume is volume. 

As was said above... if there is the capability to supply enough water, the larger hose will fill faster for sure.

Depends on the size of the outlet and the liquid.

Best answer here.

The 2 liter bottle is the best, simple way to show what its about.
