You - by then. ? Ian

Yes, mine has to go through a wall and a ceiling - thought I'd make all my mistakes with push fit first and then consider solvent weld.

As an aside, why did you choose solvent weld? I nearly did, but I haven't got the guts - or the experience.

Ahhh, sorry you meant soil pipe.... might this link help?

@Taff, I'm as you know an old git doing this build on my own mostly. Last Saturday, I fitted my MVHR first fit on my own with two hours help from a lad - push - pull - squeeze - swear. You'll be able to do your first fit on your own. We bought from BPC - the only trouble I've had is the telephone calls: one lad speaks with an accent strong enough to curdle milk. They do the design and supply. I might just get someone who knows what they are doing to fit the box next year.

Might you mean a Rest Bend? 87.5 degrees.... me being an expert and all that ?

Managed to cut and fit a noggin in between the metal joists and to screw the clip to that. Really pleased because having bent and crooked hands actually helped! It's an ill wind and all that ... Just because I can, I'll fit some builders band tomorrow when it arrives. ?

Off out again to poke around and see.....

Thought of that: there's not enough space between the pipe and the joist to reach the clip hole..... Builders' band eh? Looks like very useful stuff. Never seen it before - looked at it, but not seen it, if you know what I mean. I suspect I should keep some in stock then. Recommendations - sizes , types? Any German manufacturers to avoid? ( ?) Thanks lads. 'Nother hole you've dug me out of.... Ta!

Have a look at this .... The down-spout (?) is too close to the top chord of the POSI to fix the clip properly. And if there's one thing that YooChube has taught me, its that the fixings for the soil pipe need to be pucca. Should I; pack out the gap between the pipe and the clip and fasten, put a noggin between the top chords of the adjacent POSIs and fix the pipe clip to that, enlarge the hole in the ceiling (floor above) and move the pipe 50mm or so such that the clip can be fixed (won't be seen in the bathroom above) Where's @Onoff when you need him?

For which I am very grateful indeed.

Well @joe90, here's what I did last night.... making the hole slope at 45 degrees took much longer than I thought it would While I agree with @Jeremy Harris point that in terms of flow, I might have got away with two 92.5 degree bends, might have isn't good enough. And when I considered the noise aspect - the prospect of living for ever more with a noisy loo flush all because I couldn't be bothered to make a bit more effort ... Whats the point of doing it on your own and cutting corners? Exerience shows me I can pay other people and have corners cut aplenty. Harsh way of find out what 92.5 degree bends are for innit? ?

Change can to might be able to judge perhaps? Our so called builders had too many jobs on the go at the same time. Took ages to find out what was going on. At one stage they had five jobs running at the same time, and only 5 blokes all working on the same job : they were over-trading. @Taff, put delay to good use. Plan, plan, plan.

The waste only has about 300mm to travel at 2.5 degrees ..... but that would tend to be noisier than a couple of 45s wouldn't it? And knowing my luck if it has a tendency to block more easily, it will. Merde, Scheisse, Poo, Merda.? 'Nother steep shitty learning curve innit? Bugger. Thanks @joe90 : its obvious, you are right. Coffe and then the SDS. Damn! Cant take a joke? Don't start a self-build.

Hmmmm, got me worried for a minute, but have a look at this .... The blue line is the line of flow. The office and wetroom walls are parallel, so each pair of angles on each wall must add up to 180 Unless I'm missing something, and that wouldn't be the first time either..... Instinctively I thought 45s would do the job . It was only this morning that I tried to make the damn thing work - and found that a 45 degree bend , wouldn't lead the pipe through the hole I had cut in the concrete.... the hole was too 'square' to the floor. In this case 2 lots of 92.5 double sockets should do the job(bie) . But if I get a rush of blood to the head, then with a load more concrete hammering , 45s will do just as well.

Thanks @Temp Caught a naiscent error for me ... I'm try to plumb this bit of soil pipe from upstairs, through the wall down through the wet room and thence outside (follow the blue line) The top bend is 92.5 (just below the POSI - although the angle is not drawn to scale) and once the pipe is through the concrete from the office into the Wet Room, the next bend will be a 92.5. The next two are also 92.5s. Double sockets I think. So you stopped me making three errors. Thanks. I thought the next bend after a 92.5 should automatically be an 87.5 (following the logic pointed out by @dpmiller). Its my inability to see what a packed lunch needs to do on its way from the loo to the digester..... not @dpmiller's explanation of the obvious once its been pointed out. Ian

Thanks @PeterStarck Tell me is the display on the Supply Master Fused Spur Time Switch (called Easy View in the advert) back-lit? I find it incredibly difficult to see some of those small LCD displays when there's not much ambient light. Need a ...?

Lack of appropriate preparation

Yes

I'm no good at this am I? I just don't see it (yet). I'll get there.

Moving swiftly on , an 87.5 degree bend is 87.5 because....?

Echt? Didn't know you were a plumber.

Quatschkopf !

?

Come on then.... what's the half degree for? Come to that, what's two and a half degrees for? Tell me that plumbers ? Dare ya.
