World hand drier

[The Medway Handyman]

Had occasion to take one of these apart the other day, it had fallen (or was pushed) off the wall of the ladies in a local nightclub.

This one;

I can see why they cost so much!

Cover is a one piece casting secured by 2 torx security screws underneath - I finally got to use that security bit set I bought 4 years ago! I knew it would come in handy!

I expected the large chrome button to have electrical connections attached, but it didn't - its a spring loaded push rod that hits a microswitch.

Back plate is also a one piece casting, easy enough to re secure using the right plugs.

Inside the top of the cover were two blind holes & I expected to see 2 studs on top of the backplate for it to hook over - but nothing that simple.

Each side of the backplate is a spring loaded rod & when the torx screws are done up underneath, they contact the bottom of the rods & push them up into the holes under the cover.

Seems unnecessarily complicated to me. Why not 2 studs?

Two studs of diecast zinc won't be very strong. Steel(?) rods are much stronger for the same size. The diecasting around the holes can be made thicker (thus stronger) than a sensibly sized stud could be.

[ARW]

There is a reason for that. It allows you to take off the front cover and not worry about cables getting pulled off the circuit board.

Sounds like the Newlec hand driers. I think the idea of the spring loaded rods is for them to stay stuck in place to make replacing a the drier bastard of a job (top tip to make the stuck rods move is kicking the drier whilst shouting "move you bastards")

Did the RH rod have a dog leg?

As we are in the public loos - why can't the push down taps (Prestex) stay on a little while. Is there an adjustment that is beyond the capability of pub landlords?

Vandals.

+1! 10x the rate for 1/10th. of the time - spray the trousers, go up the sleeves...!

It's to deter you from washing your hands.

It's called a water saving feature.

Also means you can hit the button as hard as you like and not break anything.

Yep, pretty much all adjustable for both flow and duration but the means by which the adjustment can be made will be a closely guarded secret[1] that is indeed beyond the wit or interest of the site operator.

Given that, it will be a chargeable callout to adjust them so the landlord/other can either pay the 70 odd quid that would cost or keep the dosh and put up with the mewlings of the odd customer that can be bothered to bring up the problem.

[1] Certainly secret once paper instructions have been binned by the fitter

[The Medway Handyman]

Non Concussive taps they be called. I've fitted lots of these in pubs & bars. The instructions are so secret they don't exist :-)

AFAIK you can't adjust them at all.

[DerbyBorn]

You must be the culprit!

Since raising the point it seeems that some makes are adjustable - others quote 2 seconds - working on the equilibrium principal.

The non concussive bit must be an oxymoron given the amount of abuse they get for their failures to operate as intended/designed.

Yes, toolstation's best are preset but I did a quick google check before posting and there are plenty of adjustable ones too.

eg:

Taps&subrange=Push+Taps&article=Push+Tap+-+Hot+

or

"With a DVS selectable flow rate push tap installed, the flow rate can be adjusted to run from 4 ltrs per minute and the time on can be reduced to between 3 and 11 seconds. The biggest benefit however is that the push tap cannot be left running, as it self closes. This is particularly important in public toilets."

On the secrecy front however there appears to be no link on the site anywhere that tells you how to adjust them :-/

That said, the preset toolstation ones say they will stay on for 8-10s which in my view isn't that bad:

oh, and for comedy effect, watch out for hand triggered driers triggering on people walking into toilets. We had one that used an in-case PIR to detect hand heat but was sensitive enough to pick up long wave IR reflections off the glossy tiles when people walked in.

[Chris J Dixon]

I hears of some scrotes who discovered that, if you stretched cling film across a sink with sensing taps, the surface movement was enough to keep the tap running indefinitely.

Software clearly missing a maximum "on" time.

Interesting, but I wonder how much they are?

Wearing a hi-viz with reflective stripes causes that as well :-)

[PeterC]

If a tap carries on too long and is showing no sign of diminishing flow, I pull the top upwards and that usually reduces the flow to a trickle then it stops.
