Sprinklers
Amazon Basics AMZ622534EU
A three-arm rotating sprinkler that states the pressure its coverage figure assumes — which four here do not.
The number that is stated properly
About 140 m², at more than 4 bar.
That second half is what makes the first half mean anything, and four of the
seven sprinklers on this shelf omit it entirely.
A sprinkler is a nozzle. Water leaves it at a speed set by the pressure behind
it, and how far it travels follows from that speed. Quote an area without a
pressure and you have quoted the best case and left the buyer to find out.
One other sprinkler here publishes two pressures with two results, and the
difference is nearly a factor of two in throw. So the pressure is not a
footnote; it is half the specification.
And the honest reading of “more than 4 bar”
Four bar is a healthy domestic supply and it is not a universal one.
Mains pressure varies with the district, with the height of the house above the
main, with the time of day, and with whether anybody is running a shower. On a
long hose it varies again — friction takes pressure out over 25 metres,
especially through a half-inch bore.
So 140 m² is a figure for a good tap and a short fat hose. A tap at 2.5 bar at
the end of a long half-inch run delivers less, and nothing here says how much
less.
What 140 m² looks like
A circle of roughly 6.7 metres radius — about 13 metres across.
That is the shape problem with rotating sprinklers, and it is worth stating
rather than treating an area as an area.
Lawns are rectangles. Circles inscribed in rectangles leave dry corners and
overlapping wet stripes, and covering a 13 × 13 m lawn with a 13 m circle
means either four dry corners or moving the sprinkler four times.
The oscillating sprinklers on this shelf water rectangles instead, and that is
the main reason to choose one over the other.
Three arms, twelve nozzles, 45 to 90 degrees
The adjustment is the arm angle.
A low angle throws further and flatter — more reach, more drift in wind,
more water landing on the far edge and less near the middle.
A high angle throws up and drops the water closer in — better distribution
on a small area, much more affected by wind, and more evaporation on a hot
afternoon.
Twelve nozzles across three arms at several angles is an attempt to fill the
ring rather than just the edge, which is the classic failure of a simple
rotating head: a wet circle with a dry middle.
The one physical specification on this shelf
24.1 × 20.1 × 10.4 cm.
No other sprinkler here publishes its own size, and it is worth knowing: a
sprinkler sits on the lawn, gets stepped on, and gets stored somewhere.
The base is described as weighted and non-slip with thermoplastic rubber side
handles, which addresses the other thing rotating sprinklers do — they walk.
Reaction from the spinning arms drags a light head across wet grass and into a
bed.
3/4 inch BSP
The thread on the inlet, named, which matters because it is not universal.
Most garden hose fittings on this site’s connector shelf are half-inch. A 3/4
inch BSP inlet takes a standard tap-style adapter, and the listing says filter
discs with a rubber seal are included to make the joint leak-free.
