Mine stopped working this morning, how do you take them apart?

[dave f]

I don't think you can mine is playing up some times it works ok then other times it only lets a slow flow out very strange I may do an investigation on mine at some point.

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 .

Thank you!!!

Maintenance on them will be alot easier now.

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 
I tried twice!
I must be crap! Just doesn't turn off.
Oh well best order another one.   

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.

OK cheers, i'll give it another go.

The bloody idiot has taken the video down , cheers Steve.

[P @ F]

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.

Dont be so tight and just buy a new one

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.
