Where to buy a hosepipe
 

Hi, I need to buy a hosepipe that is 250m long. Is there somewhere that I
can buy one, perhaps straight from a factory or something?

What is it for, and why such a length?.
My estimation is 820ft.

Anyway you have two choices, first to make it out of standard lengths
bought from a wholesaler or DIY store and use couplers. Or get a list
of various makes as supplied from your local DIY store, and search the
web for the contact details, and ring the sales office for price.

Try a farmer's store - where they sell cow pruners, sheep openers and
the like. These are great fun to shop in - all manner of weirdness, and
the proces are often good too (3kg of copper sulphate for a tenner!)

However 250m is _very_ long. You may need significant water pressure and
you'll still get poor flow. Make sure the hose is big enough diameter.
If possible, use a shorter hose with couplers - when you can, just used
the short length alone.

At that length you might be better of with a larger bore irrigation piping
system in ldpe - see

http://www.growell.co.uk/c/32/Irrigation.html

for example. They do 13mm and 19mm systems.

A cheap flexible hose that length will put up quite a bit of flow
resistance.

Good luck coiling it up neatly after use. My 10m one fights enough. ;-)

There are a number of useful calculators on the web (e.g.
http://www1.agric.gov.ab.ca/$department/deptdocs.nsf/all/agdex787) that will
calculate pipe losses. The losses tend to increase non-linearly with flow
rate, so that head loss over 250 metres can be significant at anything over
a trickle in small hoses.

250m.
Comparing to a 30m length of hose, that's 8 times longer.
Or if a standard mains pressure is 3 bar, or 30m of water pressure,
you're looking at about 4m of water pressure.
About equivalent to a normal length of hose on a tap fed from a cold
water tank in the house.

Probably not even that good.

I got a new 30m hose on a reel earlier this year (how _did_ I cope with all
that excitement at once?!!!) & being a lazy toad & eager to use it I
connected the existing hose (about 13m long, for some reason) to the input.

The flow rate drop was dramatic - one of those sprinkler gun things on the
end of it went from being "very good" to "usable but not great" in an
instant.

And that was with a mains feed to the cold tap & pretty decent water
pressure.

The numbers are right.
Flow rate depends only on pressure drop per unit length (well, apart
from the fact that a hose may bulge at high pressure).
Some hozelock-type connectors, especially some "stop" fittings can
gramtically reduce flow rate.

Was that a dramatic error ?

Machine Mart can/used to be able to order in extra long lengths on the hoses
they stock.

Sigh.
Took me ages to spot that, when I was looking for a typo.
Oh well.
At least that particular mistake diddn't leave floods of water on the floor.

unless it is of substantial diameter the flow ill be very poor.
Probably better to get a roll of pastic mains water pipe, and use that
instead.
