I've not taken one apart so can't be sure, but some time ago I'm sure I saw a vid or someone described taking one apart.  The cap that secures the moving part of the valve I think fits like a bayonet light bulb fitting.  It twists and locks.  I believe removal is reverse of fitting.  As I say I've never needed to try it.  I'm sure I will some day.  If you figure it out let us know.

Have you tried lowering your water pressure.  I discovered mine won't work at 115 psi.  They shut off but won't reopen.  Turn the pressure down to 100psi or less and they're fine.

Steve once put a video up of taking it apart to change the washer in it. unfortunately he took the video down. 

I'm guessing that it meant all you needed to replace was a washer, but now when they stop working we have to buy a whole new unit.

From what I remember there's a little indentation on the side of the univalve, which he pushed in, and this then let the bottom piece pull out completely, revealing the washer. (I think)

I've got a broken univalve in my garage that I keep meaning to look at. Once you've got it apart, it's just a case of finding the washer size, bobs your uncle.

Cheers guys, I might pull it apart. Even if I just keep it as a spare.

I took mine apart , put some lithium grease on the o ring and put back together again , was like new again , might even pay to put it in hot water for a while , maybe get the shape back in it .

I'm so lazy I'm getting tired of it !

Cheers guys. I took mine apart, put some lithium grease on the O ring, put it back together and now it doesn't work at all  ;D
I tried twice!
I must be crap! Just doesn't turn off.
Oh well best order another one.   ;D

So i've been working for the last few days with a standard on/off tap which is a bit of a nightmare in terms of speed. However my shoulders have preferred it. Rather than leaning back to pull a hose! Funny how things happen.

It works on the same principle as a Parker Jotter pen does. The mechanism should turn/rotate easily when apart. Sounds like something is jammed inside the mechanism stopping it from releasing and rotating.

No , what happened was .....Steve put it up , then decided to take it down , i managed to get a copy along with some others , i then reposted it and noticed that Steve subscribed to me on Youtube , not knowing if i had upset  Steve or broken any copyright i decided to remove it , rather than get into any grief , i thought once in the public eye that was it , not wanting to get my arse sued though ,
However i might know a bloke that has a copy , if i had your email i might be able to put you in the loop  ;)

My oldest one (20 months) started playing up a bit recently and I did manage to take it apart and regrease it with silicon grease. They are very well designed, but once they start leaking out the bottom end I think the only way to fix it will be by replacing the larger o ring inside. Regreasing it won’t stop it for long in my view as the pressure will force water past the grease.

... and Steve knew that so he fitted an O Ring that isn't available off the shelf due to its diamensions.   

He also doesn't sell them as a spare.  :D

The irony is:
I managed to fix the univalve and got it working great, but then decided to change the pole hose (the hose I was using was too flexible and probably caused the problem in the first place).
Then I snapped the end off the univalve trying to get the 'O' ring off.  Grrrrrrrrhhhh!
£50 later.... :'(

I don’t know how you got your o clamp off but I never liked the way it was demo’d with the o clamp pliers.  Looked as if it would destroy the plastic under the hose as easy as that.  I cut mine off with a cheap dremel type tool when I was using them. Now I use PU pole hose without an o clamp and cut the hose off carefully with a craft knife if I need to remove it.
