Hose reels
Mixwise ZYW019-S20
A wall box with a centrifugal brake and a stated burst pressure — 600 PSI, which is about 41 bar.
What a wall box is, against the rest of this shelf
Three products here are carts: a drum on wheels, wound with a crank, that
you push to where you are working.
Three, including this one, are wall boxes: a case bolted to a wall by the
tap, with a spring inside. You pull the hose out, it locks; you tug, it winds
itself back.
The trade is simple and it is not about price. A cart goes anywhere and needs
winding. A box winds itself and never moves.
The centrifugal brake
Named in the listing, and it is the component that decides whether this
category is pleasant or dangerous.
Twenty metres of hose on a spring-loaded drum stores real energy. Release it
unbraked and the hose comes back as fast as the spring can pull it, with a
metal nozzle on the end travelling across the garden at whatever height it
finds.
A centrifugal brake works on the drum’s own speed: the faster it turns, the
harder the brake bites. The hose returns at a walking pace regardless of how
much is out.
Two of the three wall boxes on this shelf name one. The third names none, and
publishes one feature line in total.
600 PSI
The only pressure figure published anywhere on this shelf.
600 PSI is about 41 bar, and it is described as the burst pressure of the
three-layer PVC hose inside the box.
Burst pressure is the point of failure, not an operating pressure. Read against
the hose shelf on this site, where published burst figures run 18 to 30 bar,
41 bar is a high number — and the one hose there that publishes both a working
and a burst figure gives 9 against 18, a factor of two.
It is also, oddly, an imperial figure on an otherwise metric listing. It is
reported here as published, converted.
180 degrees of swivel
The bracket turns, so the box faces wherever you are walking.
That sounds cosmetic and it is not. A fixed box pays out its hose over the edge
of the drum whenever you work off to one side, and a hose dragged sideways over
a lip is a hose that chafes and eventually kinks at the mouth.
A swivel keeps the hose leaving the box in line with the pull, which is where
the wear is avoided rather than managed.
The winter problem, and the answer
A wall box is a plastic case, full of water, on the outside of a house.
Water left in it through a hard frost expands, and it splits the hose where you
cannot see. The spring and the ratchet do not enjoy ice either.
The listing names a quick-release on the bracket for exactly this: take the
box down, drain it, put it in the shed, rehang it in March.
That is the whole maintenance requirement for the category and it is worth
knowing before mounting one somewhere it cannot be lifted off.
What is fixed, and stays fixed
The hose is part of the product: 20 metres, plus a 2 metre feed to the tap.
You cannot fit a longer one. If 20 metres does not reach the end of the garden,
this is the wrong product, and the carts on this shelf take 60.
