Drip irrigation

Fifty metres of recycled rubber with a quick coupling and a hand valve, rated at 4 bar.
Fifty metres, ready to lay
The longest soaker on this shelf, with a quick coupling already fitted and a
hand valve in the line.
At about 1.00 € per metre at the German price recorded here, it sits in the
middle of a shelf that runs from roughly 0.80 € to 1.81 €.
What it is for is obvious from the length: a large bed, a long hedge, a
vegetable plot laid out in rows, a boundary planting. Fifty metres is not a
patio product.
The valve, and why it is the important part
Only two soakers on this shelf have one.
A porous hose leaks along its whole length, so pressure falls as you go and the
hose weeps hardest at the tap end. On fifty metres that gradient is at its
worst — turn it up enough to wet the far end and the near end is a puddle.
The way to flatten it is to run the whole thing gently, and a valve at the hose
end is where that adjustment is actually made. The tap is round a corner and
shared with everything else; the valve is where you are standing while you look
at the soil.
On a fifty-metre run, this is not a convenience. It is the control that decides
whether the far twenty metres do anything.
The 4 bar rating, next to the shelf
Published as the operating pressure.
Another soaker on this shelf publishes 1 bar maximum, explicitly “in order
to achieve even watering”, and adds that a low pressure is what the product
needs to keep working satisfactorily.
A third publishes 3 to 6 bar.
Three manufacturers, the same category, and a range of six to one in what they
consider normal.
This page does not resolve that. What it can point out is that this hose is
supplied with a valve, which is a manufacturer providing the means to run
below the rating — and that the physics of a porous hose favours running it
gently regardless of what the rating permits.
What goes unpublished
A flow rate.
That is the number this shelf is otherwise compared on, and the spread among
the products that do publish one is extraordinary: converted to litres per
metre per hour, this shelf says 6 to 8, about 20 to 39, and 46 to 76.
On fifty metres, the two ends of that range are 300 litres an hour and 3,800
litres an hour.
Borrowing a figure from another product to fill the gap would be worse than
leaving it empty, and this page leaves it empty.
Recycled rubber
Named, and it is the standard construction: ground rubber crumb bound and
extruded, with the gaps between the particles forming the pores.
Three of the five soakers here say so. The practical consequences are the same
for all of them — heavy, black, and stiff in the cold. Fifty metres of rubber
crumb hose is a substantial coil to carry, and a tight corner in March wants
warming up rather than forcing.
1/2 inch inside diameter
Published, which two soakers here do not.
It matters on a long run: the bore is what carries water to the far end while
the whole length is leaking, and a narrow bore runs out of pressure sooner.
Half an inch on fifty metres is the standard arrangement, and it is part of why
the valve is there.
Availability
From 50 € to 57 €, that being the spread across the German, French, Italian and Spanish Amazon stores on the day of the survey.
Beyond the euro zone, the British Amazon store prices it in its own currency, which the spread above sets aside.
Nothing came back from the American Amazon store at all; the buy button there runs a search rather than opening an empty page.
