I thought that was you.

Can we all look at that pic again. 

Is it just me or does the 

reducer from the grey 22 to the white 15 not look like it is pushed fully home. 

@recoveringacademic have you actually got any water drips or just on the valve that floor looks very stained for a small weep. 

[ToughButterCup]

@Russell griffiths, its a very slow weep. If I draw my finger across the bottom of the valve,  I can see a fine film of water.... (now that I know what to look for )

Yes. But I'm also taking the plumbing bull by the horns (Bit like @jamiehamy) I've been scared of it the whole of my life, but not any more.

'... Lockshield valve...'  It's just a plain valve isn't it. What does it lock and what does it shield?

 

I don't know why it is called that.

 

Unless you have a thermostatic valve, then you in fact have the same valve at each end of the radiator.

They normally come with 2 different caps.  One turns the valve stem when you turn it. The other is just a cover and cannot adjust the valve. Normally you adjust this one to balance the flow between the different radiators. Once set you put the cover on so it can't be adjusted so I guess it's locked and shielded?

The name is literal.  Exactly you say, both valves(if you don't have TRVs) are the same, but to allow one to be set at a fixed position when balancing the system a shield is fitted over the top to lock the spindle in the set position, hence the name "lock shield".  The shield is only there to prevent the valve that end from being accidentally moved and upsetting the balance of the system.

 

Last time I bought any standard radiator valves (many years ago now) they came with both a handle and a lock shield in the box, so could be used for either job.

Well lets hope that you are good with a surf board and want to travel downhill.

Finding the names of things is half the challenge, easier when starting new but replacing... Ooft!

Ever industry has its own 'language'.  There is a theory that it is to keep people out and promotes protectionism.

Having just been away for a month, I noticed that 'the locals' spoke in statements, one sentence, one meaning, only.  This stifled debate and was quite tiring to listen to.

And they had no idea about irony and general humour.

Couldn't you just buy some time with a power flush?

Surfaces of rads etc that get rusty and corroded won't be helped by a power flush. That'll only realistically get rid of the water-born particulate and slightly loose material.
