Thanks, yes a very good video, but a key difference - see below. It's a wall that's sat on the floor - if I take the entire floor out, the wall falls down, if I do the floor in very short sections, it's harder to make a decent job of fixing up the butchered battens. But the key thing I think...

I know this has been asked before - and I've read some of the answers which seem to come down to : * Make sure boards have been kiln dried & acclimatise for at least a couple of weeks. * Little difference between redwood and whitewood pine. * T&G red/whitewood boards -> ply -> OSB or chipboard...

Our old Stihl strimmer has packed in, and the local dealer says it's too old to get parts for ("it probably has a "Made in W Germany sticker somewhere on it" the mechanic said) - but I'll look into that another time. So it thought, the split shaft tools I inherited has a strimmer - but the...

Thanks to Wikipedia, it's a "small species of falcon from the Northern Hemisphere, with numerous subspecies throughout North America and Eurasia."

Why ? If it's a one off, just notify, pay the fee, and send in your certificate/test results. My experience is that LABC are only interested in having a piece of paper that's a) plausible, abd b) has someone's sugnature on it. This paper is to cover their backsides.

How do you come to that conclusion ? One reason for not giving out the previous report is to prevent "copy & paste" testing. And adding "something" does not automatically mean the installation (I assume that's what you mean by "it") has to comply with current regs - that depends on what was added.

I know we can do that ... if we remember. Having taken some cylinders apart for a look, there's no fundamental reason they have to be as they are - other than "that's how we've always done it" :rolleyes:

A while ago, while looking for something else, I came across a video on Youtube where someone was making a big deal of selling euro cylinders with "stubby" keys that can be left in without stopping the other side of the lock being used. so you can leave a key in the inside without locking anyone...

Err, so what does the lever on the front do ? It will exercise at least parts of the mechanism. Assuming these work, there is very little left to go wrong.

As I wrote in post 25 above, MCBs have very little to go wrong, while RCDs have much more to go wrong. These days we tend to consider them "reliable", but I suspect they were far less so back when the regs were written. Plus, you need overcurrent protection anyway because the RCD does nothing...

Note it only says an RCD can't be the sole protection. I can think of a number of reasons, or possible reasons : * An RCD doesn't give any overcurrent/fault protection for a L-N fault. I haven't looked at the regs, so in this context is that a valid reason ? * As I've mentioned, while there is a...

The detection mechanisms are different. MCB, the magnetic field pulls on the trip mechanism - more field, more force. It also operates at high currents, so would need a massive DC component to come anywhere clise to the AC component. RCD, there is transformer action where rate of change of...

That's probably easy to answer. A DC component will add to the magnetic field on half the mains cycle, and subtract from it on the other half. So in extreme it could delay tripping by half a cycle ... approximately. Worst case the fault occurs late in a half cycle - so doesn't trip. The next...

LPG is one of those "here be dragons" things. There's still a lot of ignorance and misinformation going around. Some garages may refuse them simply because they don't have the skills/knowledge to handle them safely - not, as pointed out, there's similar risks with petrol (also heavier than air...

I had assumed absence of a functional CPC. You can never rule out a parasitic earth path via a person ... If you consider what's in an MCB and an RCD, there is going to be a massive difference in PFD (probability of failure on demand) - I'd guess an order or two difference. Essentially, you've...

Just my 2d worth. Another vote for Aico. I too prefer hardwired if possible, but you can mix & match with Aico. In the flat, I have two heads on one hardwired circuit, and a head and test switch hardwired on another. Two heads have radio modules which link the two circuits. One annoyance is that...

I took that as someone bought it from Temu, but I see now - a freeby from Temu. They need telling it's dangerous junk - though I suspect they have a filter for that straight into the bit bucket.

A cloth is better as you can clean the cable without getting your hands sh...dirty.

Free gift from whom ? If it was a business, need to tell them they've broken multiple laws - and they need to recall any others they've given away. If a family member or friend, I'd suggest they need to send it back and report the seller.

You've mentioned a lack of space, do you have a basement/cellar ? If not, is there any space under the ground floor ? Just looking for an alternative location for your break tank and pump - to free up space for a hot tank (unvented cylinder or thermal store).
