Thanks guys. The knurled ring wasn't loose and pressing down on the head didn't achieve anything, so I unscrewed the ring and took the head off completely. As you can see from the photos, there's green corrosion emerging from under the spindle and the spindle itself is showing surface...

First thing I tried, oddly enough. Doesn't work.

I went to turn a rad back on at its thermostatic valve, and whole white plastic assembly just spins as one piece - both the upper section (the part with the number scale, that's supposed to turn) and the lower "collar" section with the little arrow pointer. You can turn it endlessly in either...

I bought these hose barbs so that I could build a one-man vacuum brake bleeder. They are listed as 1/4" PT male thread, but when I measure across the threaded section, the width is 12.6mm, which is 1/2". So what am I missing here? And do I need to use specific PT thread nuts, or will any 1/4"...

That's an old photo, and the red light isn't actually on. And he was just the guy come to do the annual safety inspection. He wasn't an engineer called in to diagnose the problem.

Boiler is Worcester 14/19 CBi, cylinder is this one:

We just had our annual boiler inspection (unvented cylinder), and we mentioned to the bloke that we've had an ongoing issue with the CH working normally, but no hot water through the taps unless we run the immersion. He had a look, did a test that involved a loud noise in the pipework (I wasn't...

I swapped the stats over at the weekend and the problem stayed the same, so I guess that points to the zone valves? Although I suppose there's still one more thing to try, which would be to replace the button batteries inside the stats (that I didn't know existed until I popped them off the...

It's not, that's the issue. I've been through all the temp/time settings and none of them go higher than 21C. Despite this, if we don't switch the CH off, upstairs will get up to 28C (as happened this morning).

At the risk of sounding stupid, I presume that our CH is multi-zone, hence the ability for the upstairs temp to be controlled independently of the downstairs? This being the case, presumably the stats are hard-wired to their respective zones rather than being assigned through a programming...

Cool, I'll give that a try tonight. There is a battery compartment on the front of each stat, so I'll try new batteries as well.

We've just turned the CH back on for the winter. It's controlled by two Drayton Digistat +3s, one in the hall and one on the landing. Every night since turning it back on, downstairs has been fine (21C) while upstairs has been sweltering (typically a displayed 24C). I've been through the...

I've inspected it closely now, and the float is *not* touching the cistern at any point. When I flush it drops down, but when the flush has finished, nothing happens. If I give the float a gentle push downwards the refill happens, and then the float rises back up and stops the refill at the...

Thanks guys. The float *may* have been changed within the last year, but I'm not 100% on that.

Our downstairs toilet has gradually got worse at refilling after a flush. It got to the point where tugging the flush handle *upwards* a few times would cause it to refill, but now you have to remove the cistern cover and briefly pull up on the black plastic thing with the slotted cross-shaped...

It is, but it's not heating the water as well as it used to. It used to be able to get it steaming hot in a big enough quantity to fill the bath, but simultaneous with the loss of non-immersion hot water, it now only gets it warm, and the water starts running cold before the bath is half full...

Thanks for your help, everyone!

Thanks for the replies so far - here's a pic I happen to have on my phone. I can take more detailed ones when I get home if necessary. You can see the Honeywell valve on top of the horizontal pipe that connects to the front centre of the cylinder. According to the diagram in the front of the...

We have a Worcester 14/19 CBi downstairs with a cylinder upstairs. We've suddenly lost our hot water, but the CH still works fine. Googling around the subject, this immediately sounds like a motorised valve failure. When I adjust one of the room stats upwards, the "demand" light on the boiler...
