Hey Woody thanks for your info there. But if surface condensation is what the meter is reading, how come areas where there are no stains is reading zero or 1%? It's only the stained or damp damaged ares which read anything from 15 - 38% from what I've discovered. Is that just reading the salts...

We have a sea front Victorian property which had damp from poor guttering and chimney flashing. The chimney was removed down to the tray and rebuilt as part of a restoration grant 12 years ago and I applied stain block and repainted the huge D shaped damp stain area. But after 5 or 6 years the...

Thanks DeltleSchmitz, I was thinking it may be something like that. Is there a specific spec I need to look out for, it's for 5x lights.

I want to replace some 20W dichroic halogen MR16 down lights with LED versions but the bulbs I've bought just flash for a split second when switched on (pic attached of bulb spec). Why this is happening and what could I do to solve the situation. Thanks for any help.

I have a Victorian home and notice the woodwork, much more so on the pitched pine doors and windows/frames is nowhere near the brilliant white it was at the time of application. Research online says it's the light which eventually turns white paints yellow but some of the non pitch pine...

I've been fitting shutters and blinds for 20 years - old houses have crumbly walls and often the hole becomes larger than the bit size so the serrated teeth type are brilliant as they hammer in nice and tight whereas the proper sized normal style will not grip.... simple as that!

Because they'\re crap - spin round. The serrated teeth ones are bliss to use.

First link bang on, 2nd link nothing like it - has to have the serrated teeth, superb to use! Great cheap and good then!

Trying to find a supplier for this type of rawl plug with the serrated edges as had a stash from something I must have bought but cannot find the same type to buy... anyone any idea what it's called, I'm Googled out!

Hi, I wish to fit 12v LED lighting in a caravan but have it so it'll work off the mains hook up but also off my leisure battery. Being that the LED's are already 12v, do I just need n adapter to unplug from a 240 plug and connecting to the battery?

No it's 2 port I need - just happened to be a cheap 3 port 22 on eBay so wondered.

Do you mean the 22 vs 28 2 ports or the 2 and 3 ports? I assume you mean the latter?

Thanks, but I assume a 3 port version won't work on a 2 port body?

Hi, need to replace a Horstmann actuator (z228) on a 28mm pipe. Anyone know if actuator for 22mm is the same/will work?

Sorted this today :) And delighted that when I took it apart rather than just buying a new one, that I saw lots of plastic had worn off to the metal ring which has the cogs on... scraped this off and bingo, works a treat ;)

Yes, and in theory that's easy to test but as you can see, it's not as clear as you've described...

OK thanks for the detailed explanation, that helps :) Soooo, is the faulty one's switch is now on forever (or until freed up or replaced) or if I switch the fused spur off, will it reset, in which case, if it does I could test each MV one by one by switching it on and seeing how the boiler runs...

Thanks but this would surely mean the rads of that zone would be getting heat?

This is fine, have done lots of wiring in the past and have a very good multimeter. But is it easy enough to explain exactly how I go about checking? The pump is constantly on and very hot unless I physically switch the boiler off so I presume I need to sort this ASAP for fear of damaging the pump?

Thanks Fezster - so how do I check this? Would that not mean the valve at fault would be stuck on open so therefore the rads are always on (which they're not)?
