    How do I get this radiator thing off (pic included)

    I removed some radiators in my house and would like to sell them. There is still part of the old valve attached though which I would like to remove. On the image you can see part of the valve that spins on the spot when spun. However, that's not the issue. Inside the radiator this piece is...

    Replacing a radiator and valves

    I'm thinking about replacing a rather boring radiator with a "designer" one, just for cosmetic reasons. My question is; can I easily replace it with a slightly smaller one? The pipes are coming up through floor tiles (see picture) and I really don't want to dig those up in order to move them...

    Curious about why a plumber would do this?

    Hi all. I am completely dense when it comes to plumbing/DIY. We recently had a leak in the valve that supplies the toilet. Inlet I think? The toilet is upstairs, but whilst fixing it, the plumber ran the taps up there, the shower and the downstairs kitchen tap. I didn't think much of it at the...

    Hi, I have a standard radiator (1/2" female bsp) on which I'm installing a new lockshield/TRV kit. The lockshield is similar to this: What happens if I remove the nut and everything on its left in the pic, and screw the valve directly into the radiator (with PTFE)? This would simplify my...

    Is this an isolation valve?

    Hi all, Hope you can help - I need to fix a leaky tap but need to isolate the water to the tap first. Directly underneath the sink are a pair of what look like stop valves just below the flexible hoses, one for hot and one for cold. Is this a stop valve? I've not seen this design before - it...

    Replacement Actuator....Again!

    Ok so this is the third central heating actuator I've had to buy in 18 months. There's obviously something wrong with the valve. Checking it out it looks like the valve isn't turning in the same direction as the actuator or at least the slot the valve fits into is not in the same direction. Am...

    Radiator 'clicking' - not sure what to adjust - see photo?

    Hi there, I recently had a new radiator fitted in our bedroom with a thermostatic valve on one side of it. At around 6am when the heating comes on the valve 'clicks' as the radiator warms up. A bit of Googling and it seems the noise is from the spring bouncing in and out and the 'fix' is to...

    Replace TRV with 8mm pipe

    I have a faulty TRV. When the pin is fully open, it's fine. But I notice it leaks when the pin is depressed and the TRV is off. I've tried giving it a tap, wiggle, and some WD40. I'm looking to replace the TRV and re-use the nut/olive - so I can swap the TRV over without having to cut any pipe...

    Trivial tee valve

    I think I'm missing the trick here. I want to convert this into an outlet that I can connect a hose to as well as the toilet cistern. I'm sure I need a tee valve but they all seem to be either 2 compression ends 1 screw on with a single lever. I want to be able to turn the hose off as well and...

    Reason for usual HW shutoff valve location

    In a conventional system, the standard arrangement is to have a gate valve on the (typically 28mm) cold feed pipe from cistern to cylinder. Out of curiosity, I was wondering why you won't find it on the hw pipe (typically 22mm) going out of the cylinder instead. Of course, positioned after the...
