Thanks for the reply. Yeah I definitely don't want that :-) I've tried not to bore you all with too much detail, but I'm doing an extension at the moment. That gives me good access to below the bathroom as the ceiling is down and to the stack. The situation I described initially is my end state...

Thoughts on the horizontal 110mm plan connecting into the stack? Thanks Jon

Thanks for the info, I'll have a read through that. Just to be clear my plan was to drop all 3 runs into the 50mm pipe individually. They'll be dropping into the top of it. I could potentially swap the 50mm pipe for a 110mm pipe that connects to the stack instead. Presumably that would be better?

The stack is the other side of the wall in the next room. It will be around 1 metre from the shower, 3 metres from the bath and 4 metres from the sink. Doing an individual run for all of them is very difficult with the access available. Is what I'm proposing compliant to regulations?

Hi all, I'm looking for a bit of advice on designing multiple new waste connections into an internal soil pipe. I'll have 3 wastes (sink, shower, bath) that I want to join into a single 50mm pipe (running at a slight downward angle on a horizontal. The 50mm pipe then connects into the internal...

Hi Woody - that i Thanks Woody. That is an option but not sure I want to put the pipe hidden in the concrete floor (if that's what you meant?). The pipe will be coming out the wall at a very low level anyway.

Thanks for the replies. I think it will need to be a 450mm wide chamber as the depth will be over 600mm. Also I think the chamber will need to have side entrances, as it will be difficult to make the pipework run into inlets which face away from the wall. What I'm still not sure of is why...

Hi all, I'm currently having an extension but I'm doing a fair bit of the work myself as well. Anyway one of the bits I'm doing is putting a new manhole in. I've replaced a clay run with plastic. This comes out of part of the extension at 90 degrees. If you look at my picture, you can see the...

So an update. I spent several hours tonight digging two reasonable sized holes next to the foundations, and then had great fun pouring buckets of water onto the concrete and sweeping muddy water into the holes. End result is I no longer have a layer of mud/silt, but I still have brown concrete...

I do have small holes that I've dug out that I put the pump into for pumping out. I might end up having to make them a bit bigger for the purpose you describe. They're still full of water mind you. Its solid clay here...nothing at all soaks away.

Thanks for the replies. Jet wash I do have, but would probably create just the same issue once things have settled down. I'll have a try of the broom and shovel idea, thanks.

Hi all, I've recently dug out my footings and have now had the concrete poured. The concrete doesn't come up to the top, and has set nicely. We've had a huge amount of rain in the days since it was poured which caused them to turn into canals, and some of the mud sides have caved in. I've...

Hi, It goes down the side of my house. This was previously built over with a lean-to side passage, but I'm currently replacing that with an extension. So ultimately it will have a concrete floor above it. There will be 500mm of soil though below the concrete floor, before it gets to pipe...

Thanks Agile Anyone else have any information on what "granular material" can be interpreted as? Cheers

Hi, I'm replacing a leaky stretch of clay underground pipe with plastic. The run is around 5m in length and around 0.5m under the ground. My question is around backfill. The clay pipe is currently just in the soil. It is sitting on firm soil/clay soil. I understand I should lay the...

Thanks for the extra info. You originally said 700-1800 per lintel so I was imaging at least 700 * 2, but 700 all in seems very reasonable especially with all the mods described. Do you know why they specified it be galvanised?

No it won't do. Would that make the price go into the £1400+ bracket (£700+ per beam) spoken about above)? I wouldn't have thought so? If so then I go back to my original question. Is two beams therefore worth it?

Thanks for the replies guys, that's helped me make my mind up. cjard - those quotes, were they just for the steel or installing the steel too? They just seemed higher than I was expecting if it was just the steel. For example at http://www.parkersteel.co.uk a 6.1m length of 203x133x25...

Hi all, I'm currently in conversation with my structural engineer about design and calcs required for creating a 5m gap in the back of my house into a new extension. He has come up with two options: Option 1. This will see two steels. One for the inner leaf and one for the outer leaf...
