The red washer / packing is definitely made of a rubbery material and not fibre. It is far more substantial than a rubber band at about 3mm thick. It looks and feels just like the sort of hard washer you may find in a tap, but looks as if it was deliberately contoured to fill the gap between the...

Thanks very much John -I'll give it a go!

Here are a couple of photos to explain. The rubber washer sits around a nozzle in the brass control value. You then align the value to a hole in the black pipe and use the clamps to hold it in place. The idea appears to be that by clamping them together like this you can create a tight enough...

Thanks John - I didn't realise that. Which other connection are you referring to? In the photo I attached, I've got the brass control valve (and you can just see one of the "good" washers in place), and it is assembled next to the hole in the black pipe, which carries the gas from the bottle...

Thanks guys. Yes, definally rubber/silicone. It's not flat though, but moulded to the shape (although I guess that may just be through compression)? Is it possible to replace these?

Here's a photo of the washer in place. It creates a seal between the control valve and the black (horizontal) pipe.

Recent hot weather meant I dusted off my old gas BBQ and fired it up. After a few minutes I found flames come out behind one of the control knobs... :(Disconnected the gas and took it apart. Gas bottle feeds a horizontal pipe which runs behind the knobs. The knobs then open a valve to allow the...

(Back to my original problem!) Found the second valve. I took the motor off and checked the valve itself - moves pretty freely by hand (40 degrees or so). When I reconnected the motor and flicked it from auto to manual I couldn't hear the same whirring I heard when I did that with the hot...

Found one of those (Honeywell 272848) next to hot water tank but can't find a second one? Toggled the one I have to manual and back to auto to see if this makes a difference.

Do you have the same combination of timer + boiler? Is there the potential for some sort of "compatibility" issue between them?

We had a Vaillant ecoTec Plus 630 combi boiler + Honeywell ST9400C timer installed a few years ago. Everything seemed to go well until last autumn when we realised that the (water) underfloor heating in our kitchen was warm in the morning even though the heating should have been off all...

Thanks guys - you are right there was a small bit of water in the pipe. After I posted I cut the pipe further up, and realised that the new piece of pipe did solder correctly, and the joint into the old pipe hadn't been soldered at all - and there was damp inside. What with practising and...

I'm having a problem getting a solder ring to attach properly. I'm new to using solder rings but I took the advice here and practiced a little on some scrap pipe. I clean the pipe, apply flex, heat and end up with a perfect joint - nice neat, even solder appears. When I do the same thing...

Thanks for all your help guys. Time to invest in a shiny new alarm....

Thanks (even though this isn't the best news!!) Is there anything I can salvage here? The current system is hard-wired. Can I keep the existing contacts / PIR and just replace the main box / keypad? Or do you really recommend binning the whole lot? Can you recommend a good supplier for...

Thanks. Some photos below;

Over the summer I bought a house with a burglar alarm fitted, but we've got no manuals, no codes, no nothing for it. We asked the previous owners, but they said that they never used it! We got ADT round to look at it and they tried to flog us a contract at £20+ per month for "bells only"...

Apologies if this is a stupidly silly question, but I'm stuck on how to touch up some paint chips on my car bonnet. I cleaned up the chip to make sure there was no rust around. Applied some primer and left it to dry for at least 24 hours. Gently spray painted the spot with some paint from...

I really hope not!! Some photos; When we moved in we got an independent periodic inspection certificate which said that we didn't need to rewire (huge sigh of relief). Although we didn't have to, we did decide to change the fuse box over to a new breaker box, which is why this looks new -...
