George's spray blocked

[Dave]

I don't know what happened to my last post about this, so here it goes again.

I have george vac/shampoo machine and the spray nozzle on the shampoo adapter is blocked. How do I remove it to clear the the blockage. It all came to me second hand, with no instructions.

The nozzle will either unscrew, or be held in place by a threaded cap. Remove the nozzle which may be brass or plastic.

Try not to poke anything hard through the hole - it is very easy to damage a nozzle and that can give poor spray pattern or lack of pressure. If you can use a plastic 'bristle' off a garden broom or an airline. Failing that soak it in vinegar or lemon juice overnight - it could be limescale or chemical residue.

A new nozzle wont cost much, Numatic parts are cheap as chips.

It's a brass one and my first attempt at unscrewing it turned out be to a failure. As well as this, looking at the line where the nozzles are, I though about the re-alignment after removal. Would the nozzles be at the right angle to the vacuum part.

I wouldn't dream of doing that :-)

It could be something else. Last time I used it, the spray started OK then immediately backed off about 50%. Right now I can't even get the plastic pipe off it without cutting it. I am reluctant to do this, as I don't think there is enough slack in it.

What I might do then, is remove the spray from the vacuum tube and dangle it in some vinegar as you suggested

Thanks for your advice.

I'd imagine something unscrews. On the machine I have (Non-numatic) there is a retaining cap/collar that unscrews and the nozzle simply drops out.

Try phoning up Numatic. They are very helpful and will tell you how to remove it.

Looking at it, I am certain you are right, but it belongs to the school, hence my reluctance to force it.

It is resting in vinegar at the moment.

I have had a look at it and it looks like there is a no pressure valve in the spray nozzle. I have been told that I should be able to blow it open. So far, I can't.

Failing that, I will do as you suggest and phone Numatic and see what they say.

This all started when the head mistress asked me to shampoo the staff room carpet (the staff live there like pigs, by the way) on Friday night. After spending more than half an hour curing the leaks, I found that the spray was totally blocked. I won't know if it is working until Sunday, sometime :-)

Thanks for ever one's input

I have just cleaned mine by gently using a air compressor and blowing it through from both the trigger end (with the trigger held), and the jet end. Really easily cleared. Cheers Pat

Dunno, this might help...

It's nearly ten years since he asked, so I expect he's either fixed it or thrown it away.

[Bob Eager]

Well, he did ask nearly ten years ago....

But as it happens, here;s some George advice...

Make sure you run plenty of clean water through it before putting it away. One of my sons didn't, and the pump seized up.

It took me white a while to strip it down, remove the pump, dismantle the pump, and clean out the shampoo residue.

Sorry, I've just been kissed by a handsome prince and was a bit flustered. Good Lord, is that the time?

Hello we have a Henry wash carpet cleaner .we used once couple months ago clenead and stored .I tried to use today but it does not spray water . Also I realised it's no sound when I turn on the water ... What could be the problem??

[Bob Eager]

We have had this problem.

It's essential to run a quantity of clean water through it before storing. The carpet cleaner tends to gum up the pump.

To fix, take the cleaner apart (screws under the top) and extract the pump (a bit more dismantling required but nothing difficult). The pump is a simple device - a cylinder with a vibrating slug and a non-return valve consisting of a ball bearing and a spring. I can't remember just how it comes apart, but it should be obvious. You are left with a tube with a slug stuck in it. Push (knock!) it out - this may take a bit of effort depending on how badly it's stuck. Clean the slug and the cylinder thoroughly until it slides freely. Reassemble and test!
