I've bought one of those hex shank chuck adapter on ebay and tried a 6mm drill bit in it - it wiggles like hell and the wiggling diameter is more than twice as large as the drill bit size. I haven't trying drilling yet (just in 'open air'), but hope that touching a "to be drilled object" will...

Yes will do thanks

Got it, will try one then. Misunderstanding on my part, apolgies. My terminoligy is this: what's in the front of my drill (integral part of it) I call "socket" (i.e. female hexagonal receptacle) What you insert into the socket - I call bit holder (hexagonal male at one end that goes into...

a whole new world to me :-D ))) Thanks a lot rsgaz! hex shank chuck adapter looks good but I worry it might a bit heavy and lead to conical (rather than purely centralised) drill movement. I notice this conical movement even on hexagonal screwdriver bits, which is not crucial for screwing, but...

Dear Forum members, I bought a Cordless Combi Screwdriver/Impact Driver PDSSA 12 A1 with hexagonal socket. According to manual it works as a screwdriver and can be used for drilling (here is the manual). However, I am totally bewildered as to how fix a drill bit in it if it only accepts a...

All clear guys, thank you very much for your explanations and input to the discussion! :-)

There are quite a few that claim "no small job is too small", and all 3 from gumtree I contacted - replied, so I will find one no doubt, the question is still trust/quality, however. I don't know for sure, but leak#2 above the transparent roof (see red circle) was fixed by our builder 4 years...

There was moderate rain this night for couple of hours - no sign of leakage. So what I'm thinking is that tiling itself isn't a problem, but in heavy rain when gutters get over flown excessive water rushes above the tiles and penetrates beneath them which creates leak. Does this make sense...

I am not sure where you see a sprocket? The white at the bottom of the tiles is gutters. I think the bottom tile row does overhang the gutter maybe by ~2 cm or so. I will double check tomorrow but my recollection it does. PLus the thing to bear in mind - this is the ORIGINAL tile roof (1928...

Thank you for the suggestion that sounds very reasonable. Unfrtunately that is a bit complicated for me as I have no experience, I'd rather pay a good roofer to do it. Actually the leak has been "fixed" a couple of days ago by a gumtree roofer, but I think he didn't do it well. What he did was...

Water is dripping from part of the ceiling which is underneath the tiled roof.

Dear forum members, Our flat roof above car port attached to bungalow developed a leak - 1l/hour in heavy rain. The part of the car port ceiling where it drips - is below clay tiled roof of the house, so water must somehow penetrate beneath the tiles. What I plan to do is to fill all the...

Excellent news - the boiler pressure stayed above 1.0 after it working for ~ 5 hours and cooling down for another ~6 hours. The PRV is not leaking either! (no water collected in the plastic bag on the PR pipe outside) There is still a small leakage in the system, like 0.1-0.2 bar over 12 hours...

Quick update: BG engineer came and connected ExV, tested boiler for 10-15 min, the pressure was increasing from 1.1 to 1.9 bar (as opposed to 3.0 bar every day for the last 3 weeks). The PR pipe outside was dry, no water dripping. I keep testing it right now and will let you know how it goes...

It's because the flexi pipe on ExV is hidden behind the condenser (see thee attach image), thus if the previous guys (2 from the insurer and one doing a service ~ 2 weeks before the leak was discovered) didn't take the condenser out - they wouldn't see it. I was told that they re-pressurised...

Here is the photo of the EV pipe and the orange cap - as taken yesterday by the gas engineer from insurer.

Thank you for explaining :-)

It just stroke me - how could the EV have been incorrectly installed (not connected) if the second engineer*) who came a week ago said the EV pressure was toll low ~0.5 bar and he managed to re-pressurise it to 1 bar? If EV were disconnected, would he managed to re-pressurise it at all?? Could...

I bled all the radiators a few days ago, so there should be no air. Hope not. We reduced the usage to 4 hours a day.

That looks very much like the pipe I saw - it was attached to EV but the other end just hanging in the air. You are right - neither PRV, nor EV are the only problems and there is a leak in the CH systems (most likely pipes) that we will deal with (re-pipe). However, The PRV is certainly leaking...
