Aladdin Isolator Valve

http://www.screwfix.com/p/aladdin-ea...ter-pack/36008

I've just bought one, as I think the mains tap won't work in a flat I'm
going to be working in. Has anyone else here used one? Seems a great
idea, but I wonder what they are like in practice?

Anyone else find it slightly surprising that this works? Does it
completely shear the pipe, and insert a gate?

It's like a photocopier. No way should that work!

It punches right through at least one wall of the pipe, and yes it must
be a rotating gate valve.

The whole thing relies on the silicone seals within the body lasting
pretty much forever.

I can't work out where the excised bits go.

Horrid idea - replace the main isolator with a pegler (or other GOOD
make) full bore 1/4 turn valve.

If the street cock won't turn off, get the water company to fix that
first. If this is the first cock after where the mains splits to feed
the various flats, there's always a pipe freezer.

They probably get flattened at the back of the valve...

Ah, yes:

(that's also why there is a minimum drill torque spec, since it needs
the power to crush the pipe).

Very cunning, I can see the appeal as an "emergency fix". Not sure I
would want to fit one to my own system as the main "post-stop cock"
isolator, though.

Still not exactly clear about where "debris" goes, and exactly where the
sealing faces are.

Come on John, you know the difference between torque and power even if
Aladdin doesn't. To quote the article which you cite:

"Installing the cutter in a standard hard 0.7mm wall copper pipe
requires 16 Newton-Metres of drill power"!!!

Indeed, but I won't begrudge them that one, since I would guess most
would equate "a more powerful" drill as one that also has more torque.

(which will be generally true unless discussing particularly highly
geared designs)

But eighty quid for a single valve with required tools, and seventy-odd

Silly bugger that I am, I missed that. So, as I speculated, it shears
the pipe completely, but then inserts a full bore ball valve unit
presumably with integral seals, the whole being sealed to the housing
with static O rings.

It's a cunning bit of design, especially as it works with metric and
both UK and Irish Imperial dimensions.

Probably just about worth it for a plumber, given the time it saves over
freezing to install a "proper" full bore lever ball valve.

I was hoping it would let you see what had happened to the pipe when it

Now the original thread for this which is on Usenet is however still

It might have been better given this is just a portal, to have either
started a new thread or at least quoted some of the old one since most
reading it are not going to go to the web site to read the back story.

My guess is that these devices are pretty crude, Anything that is supposed
to work as a tap on a working main without it being cut runs the risk of
jamming debris in the pipe and all sorts of other nasties in my view.

Sadly one cannot see into your pipe but I bet its jammed with bits of the
cutting or sealing process somehow. Yuk.

Although you cannot see it Brian, there is a Youtube video of one being
dismantled. When fitting the valve the pipe is fully cut and the debris
compressed as a slug in the recess in the back of the fitting.

https://www.youtube.com/watch?v=H9JSbIPLffM
the dismantling is after the pressure testing bit.

That is assuming that the valves have been installed correctly in the
first place and the cutter was fully wound in.

If the handle on the valve is working and can be turned than I doubt
that the debris slug could fully block the pipe and water would still
flow, maybe at a reduced rate.

One has to wonder if the fill valve to the toilet is actually the
problem and its that that is not opening to allow the toilet to fill?

I had not seen that video before, Alan, so thanks for that. It's quite
clear from the video that, if the cutter is wound fully in, the slug is
held in place at the back of the fitting by the cutter.

The only possible reasons for the OP's issues a
1. Defective Aladdin devices - both of them.
2. Incorrect installation.
3. Some other blockage.

Unfortunately, it's impossible to say which. I suggest the OP contacts
Aladdin customer service for advice.
