Drip irrigation
YAHAMOO BSV-IC018
A solar pump with a programmable timer and 20 m of tube — the only product here that needs no tap.
The only one here that does not need a tap
Every other product on this shelf ends in a threaded or clicked fitting that
goes onto a garden tap. That is an assumption, and for a lot of people it is
the wrong one.
A balcony has no tap. A roof terrace has no tap. Plenty of allotments have a
communal trough and nothing at the plot.
This is a pump: a 3 W solar panel, a 2200 mAh battery, a timer, and a
pump that lifts water out of a container you fill and pushes it down 20 metres
of tube to up to 20 pots.
No plumbing. No socket. No hose across a doorway.
And the thing that comes with that
It runs out.
A tap-fed system never does. A container-fed one delivers exactly as much as
you put in the tub, and the fortnight away in August that this product is
plainly designed for is also the fortnight nobody is there to refill it.
Sizing the container is the whole planning problem, and no flow rate is
published, so it cannot be calculated from this listing. Twenty pots, a
programme of so many minutes a day, for so many days, needs a volume nobody
here states.
The memory, which matters more than it sounds
Settings are saved in internal memory, and survive a power loss — the timer
does not need reprogramming after a restart.
On a solar device this is not a luxury. A battery that runs flat after a week
of November cloud, or a panel knocked out of the sun, means a restart. A timer
that comes back up blank has silently stopped watering, and nothing announces
it.
Holding the programme through a power interruption is the difference between a
gap in the watering and the end of it.
The alarm
Named explicitly: the system beeps when the pump or the filter is blocked or
the water is insufficient, and beeps intermittently with a flashing green light
when the level is low or the probe is blocked.
That is the single most valuable feature on an unattended watering system, and
almost nothing on this shelf has an equivalent.
Automatic watering fails silently. A soaker hose that has blocked, a dripper
that has clogged, a pump with an airlock — none of them announce anything, and
the first sign is a dead plant a week later.
An audible warning, in a garden somebody walks past, turns a silent failure
into a noticed one.
What goes unpublished
No flow rate. No head. No pump output. No delivery per plant.
For a pumped system that is the specification, and it is absent entirely.
Twenty plants is a count, not a quantity. Whether each gets a teaspoon or a
litre, how long a programme needs to be, and how much a full tub lasts are all
unanswerable from what is here.
Nor is there a head figure — how high the pump will lift — which decides
whether the container can sit on the ground with pots on a bench above it.
The same hot-water tip
Like the micro-drip kit on this shelf, the listing says to dip the end of the
tube in hot water for a minute before pushing the fitting in.
It works for the same reason: warm polythene tube is soft enough to accept a
barb, and it shrinks back onto it as it cools. Two listings on this shelf print
it; the rest leave the buyer to work it out with cold hands in April.
