Incase anyone's interested this is how it turned out in the end,
The AAV has ended up about 2ft above the basin so shouldn't be any issues there.
There's a decent fall to where it drops down into the garage so I don't forsee any issues and all the pipework is clipped in place so...
'flat' roofs always have a slope achieved by using firring strips on top of the rafters so all the water off your current roof will run onto the off the new roof.
If I remember I'll get you a picture tomorrow of our extension roof as it'll essentially be the same.
They are marked on the blue labelling below the neutral bars, N2 is hidden by the left cable (marked green), it's the next marking to the right of the N1 you can see and N4 is hidden by the right most cable (marked blue)
N2 and N4 as they are labelled below the neutral bars are the 2 cables out...
Hi all,
Back from a weekend away so I've had a chance to check a few things.
Firstly there are 3 lives in the left hand B6 for the lights so that matches with the 3 neutrals questioned earlier.
The neutrals from the main switch and between the rcds are as efli has marked in the quote above...
I'm not at home but I'm reasonably sure from memory, x goes to the right most y, from 1 rcd to the other.
Left most y is the shower, pretty sure we've established it needs moving to the right as shown with an orange line in my earlier picture.
Middle y is the same wire as left y above.
Sorry for the delay in replying.
The units been installed for nearly 3 years, never had any issues with it apart from I always felt it was quite an untidy install, the cables up the wall weren't clipped, cables inside the unit were lopped round each other etc. so yesterday I neatened it all...
Can't remember which car it was I had (definitely not a micra) but you had to turn the key one way in the lock then the other way and hold it for the door to unlock, it used microswitches in the lock activated by the barrel instead of a solely mechanical setup as you'd expect.
Personally I'd remove the centre fitting use a long 8 or 10mm bit to drill all the way through into the utility then core drill it outside in for about an inch then core drill the rest from the inside.
I wouldn't worry about the smell from the pipe it soon disappears and you won't have it open...
I've ordered from the same website, I rang the dealer to confirm a few things and they were really good.
Id ring them if you want to be sure but it should be the right item.
