Surge protection, fuses and MCBs in loft from PV array.
Dillsue replied to jimseng's topic in Photovoltaics (PV)
This! Only change I'd make is have the MC4s for the last connections on the roof within the loft so they were accessible without the hassle of accessing the roof. If you've got to change either of the last panels in the string then you can easily pull the MC4 through the felt if you've got a tiled roof. I don't know if you can do that with a slate roof so maybe MC4s outside on a slate roof?? If you want to use screw terminals at each end of strings then you'll be cutting off the factory crimped MC4s and then screw terminating them, meaning a JB on the roof or in the loft. This entails 4 screwed connections in the same way as you would for an isolator which apparently is a fire risk? From posts above, MC4s are a lesser fire risk than isolators so those would be a better bet. I think you asked in another topic about crimping which you accepted was doable and from the table above is an approved way of disconnecting a string. -
Indeed, that should be solved as well.

Rainwater pooling next to external wall
Nickfromwales replied to LLL's topic in Rainwater, Guttering & SuDS
I spotted that in the other thread. The condensate from a boiler is corrosive, so you’re not allowed to discharge that into metal pipe work. -

See this thread also Or have you just moved the problem for now? -
That is a boiler pipe.

Windows delivered - wrong internal finish/colour
Nickfromwales replied to AppleDown's topic in Windows & Glazing
Thanks for the update. Install them first to see if they offend you, and if they don’t then step away from the spray can and use the savings for bathroom fittings -
It’s having a wee !

Thanks all for the additional comments/suggestions. We are cracking on with no further discussions of said survey.

Rainwater pooling next to external wall
ProDave replied to LLL's topic in Rainwater, Guttering & SuDS
So what is that branch pipe coming round the corner then? Your other pipe further along is definitely foul waste with no inspection chamber or rodding access. -

Just as an update and close out of this - we agreed on a 30% refund. Happy with that, and we can paint some of them white (warranty won't be affected). Cheers for all the help. -
Thanks Dave. The downpipe is only connected to the gutter for rainwater. I saw the reason the pipe (not the drain) was blocked: there are trees around and the leaves dropped in the gutter and blocked the pipe. Now it is fine (though all leaves are flushed down through the pipe).

Why no more? Because we have enough already, and the grid can't connect more and get all that power down south. So they have decided sensibly, lets build more down near where most of the power is used. Drive around Scotland and it is hard to find anywhere you can't see a wind farm. Drive around England and it is often hard to find anywhere you can see a wind farm.

Week 28 - Floor tiling, bathrooms, cladding, MVHR, electrics…
Oz07 commented on Benpointer's blog entry in Contemporary build in north Dorset
Did you literally have the firm commission your mhvr or did you buy any other products or services through them? I struggled to get a decent contractor to commission even after having used a reference from supplier. Maybe an easy fix to the door is a hidden key safe somewhere. We've had one on last 2 houses its good for cleaner and unexpected visitors.- 3 comments

Well since @Pocster has been brave enough to show me (us all) his : I feel brave enough to return the favour I installed a water butt - ostensibly for the wife, but actually for the Brownie Points. And its hacking it down this morning. She came in from outside giving me one of this wifely looks, and merely gestured at the water butt As yer man would say FFS

Is this a load bearing wall?
Mr Punter replied to WhiskyInTheJar's topic in New House & Self Build Design
The layout is really compromised as can be the case with bungalows. The extensions have not improved matters. If the current setup does not give you enough space I would look elsewhere as you would have to go to considerable expense to make your required silk purse.- 10 replies

Looking at that bigger picture then the land at the top of the retaining wall has been built up too high in my opinion allowing the water to naturally drain off the top and down the face of the wall. get up the top with some gardening tools and cut back all the crap on the fence, scrape back any soil and sit and watch, I bet the mucky area in the corner is the natural run off from above. I would want a drainage channel or a sort of spoon drain up top to prevent pooling water up there running down the face. sort that bit first. the cracks I’m afraid will be very expensive to fix and I would live with them for the minute the small hole has not been filled since the wall was built and is just an easy escape route for water that is behind the wall. sort the top first then let’s see what happens. get a pressure washer on that corner so it’s clean and you can monitor it.

Why. Surely a nation what to export to earn an income. There is no difference between export electricity and whiskey, except whiskey kills more people, and smells worse than the resins used to make turbine blades. People bang on about how we do not have a manufacturing industry, why is Scotland not making wind turbines. There would be a good local market, many good engineers, experience in the marine environment, energy experts, plenty of old industrial sites ripe for redevelopment and a huge nearby market. I put this same suggestion forward down here, all I get is blank looks.

I always thought the only reason for the dpc was so the brick and stone could move differently without cracking the stone. Wet cast stone doesn't need apparently much stronger the dry cast is weaker. You only have to look at them funny and they chip

Thanks for the help. This was before the whole window was replaced with a new window and frame including the top bit as its a fake bay window. The reason for the ask was that one of the bricks not included in the picture attached had a hairline crack in it. They used a service called the brick doctor to repair the brick instead of replaced as they said their brickie couldn't source the bricks. I was surprised so wanted to ask

The report itself seems okay, it is the lousy "report it to Joe public" news article that is of the dumbed down nature. As I say, it DOES highlight Scotland has been the target for so much wind farm, and now there is a document confirming we have more than our target, so please no more. Time for England and Wales to have their share if they want the lights down there to stay on. I will be forwarding this to everyone I know .

Surge protection, fuses and MCBs in loft from PV array.
-rick- replied to jimseng's topic in Photovoltaics (PV)
Make the connections on the roof, run continous cable through some form of protection (trunking, kopex, etc) to the ground. Don't make connections inside the roof. If you are using the PV Ultra cable I guess you'll need a connection box on the roof which is a little more tricky to create space for but doable. Ignoring the detail about how the cable routes from roof to inverter I think you want all the solar panel MC4s to be accessible from the roof side. If a panel gets damaged or needs to be lifted for another reason, you need to be able to access the connections from the roof side to disconnect it. -
Rainwater pooling next to external wall
ProDave replied to LLL's topic in Rainwater, Guttering & SuDS
I suspect it is all related to that drain. That looks like cast iron, and for the plumber to bash a hole in it like that with no sensible means of covering it is just plain bad, I would not be using the same plumber again. I think that whole corner around the drain pipe needs digging up, a proper look at what is going on there. I bet you will find all sorts of problems which is why the drain blocked in the first place. I suspect that whole stack will need replacing and a proper inspection chamber put in there for it to connect to. Then all the paving can be put back and levelled. Please don't ignore it, this is your human waste going down there via a pipe now with a big hole just above ground level. -
Is this a load bearing wall?
ProDave replied to WhiskyInTheJar's topic in New House & Self Build Design
I think it is time for a look in the roof space as already suggested. To my untrained eye I would say it has front and rear add on extensions with the existing sloped roof added on and continued down. So I still think the yellow wall in your sketch is the original wall where the roof finished before it was extended. You should be able to sell by the thickness of that wall inside the house. I bet it is a thick double skin wall showing it was once the outside wall.- 10 replies

What I wish would happen is that they stopped drizzling these reports (or how they are reported) with weasel words. Terms like 'shovel ready' are a (expletive deleted)ing nonsense. Our electrical infrastructure needs a certain amount of redesign and renewal, based on need, not poncy reports to politicians. A quick search shows that by 2035, between £28 and £35bn need to be spent on the main infrastructure. I wonder how much of that is spent on getting planning permission, I cannot seem to find a number for it.
