@Kirkgas I did that, really strong mix too, wouldn't touch it. This crust is really nasty! @Agile, not so bad, various radiators and pipes have been off and not too bad. The exception to that rule was the double lounge rad - with no drain cock! Black cack ran out of it for ages. I have...

I'm not sure I can provide specific advice, but in general, here goes. Pipes can start banging for a number of reasons for example the pump kicks in and you get a pressure wave running along a pipe run until it hits an obstruction such as a valve, that can set up an echoing pressure wave...

I had a Mira PPT3 for about 7 years and it worked fine until I found a damp patch on the hallway ceiling below the bathroom. Water p***ing out of the bottom of the hot water side of the pump. Cause, shaft seal gone hard and stopped sealing. These seals are not available as spares (and never...

@Paulbrill You're welcome, really happy it helped. Just as an update (12/12/11) . Ours is still working fine so good return on investment of labour. :mrgreen:

Hi Axel Thanks for the complement. What you may not be able to see is that in the original installation between pump and motorised valve, there wasn't any tape around the olive at either end and it has seeped so there may be an issue with sealing on that joint. PTFE is a bit of an...

Thanks for the comments guys. @ Happy...We're on a bit of a budget so cleaning the can was the first option, if that didn't work, then scratch head (with clean finger) and splash out for a new one. @Andygas...Well spotted with the fuse, (bet you went to Specsavers!) that has now been...

Damn, that's a surprise about the Queen Mother! I sure hope that GW doesn't get in again and I haven't seen Elvis about for a while either. I have found that sarcastic people are generally socially inadequate in some way - not a criticism, just an observation. If info on Part P were that...

So obvious now you say it! Add the new switches in series not in parallel. Many thanks for clearing the fog of stupidity!

I have really struggles to find any useful info about what is controlled by the new regs. You may have too. Go here: http://www.iee.org/Publish/WireRegs/BR-PartP-dwellings.cfm#Q2 It gives a reasonably clear explanation of the regs and most importantly, what is 'Not notifiable' Hope it...

I have a fully functional three way circuit using one intermediate - no problem. I want to add another intermediate into the circuit to control the set of lights from another location. My tame electrician said just put the new intermediate in parallel with the existing one pole for pole and...
