Bannon Posted April 26, 2006 Share Posted April 26, 2006 I have the usual fat DIY book but no info on this. Over a 10 metre run, how much of a 'fall' should I have from the waste outlet to the septic tank inlet?Cheers guys. Link to comment Share on other sites More sharing options...
Krill Posted April 26, 2006 Share Posted April 26, 2006 If it's any help the UK ideal norm is 1 in 40 but thats a bit flexable, if you go too steep the water can run away too fast leaving the solids high and dry, not a nice subject for the breakfast table Link to comment Share on other sites More sharing options...

Michael Posted April 26, 2006 Share Posted April 26, 2006 Bannon. 1 in 40 in any country, which if you get the edge of your bubble on your level just touching the line thats about spot on.Michael. Link to comment Share on other sites More sharing options...

HoneySuckleDreams Posted November 15, 2006 Share Posted November 15, 2006 I'm doing the same thing, although I've got a 25m run. Does anyone have any info on how the underground 100mm pipe is joined? Fosse bloke says it is "interdit" to glue them so I am worried as they might leak. Link to comment Share on other sites More sharing options...

[/quote]HiThe underground pipe has a collar fitting, into which the preceding piece fits, rather than connecting two pieces together with a straight connect.It will not leak unless the run backs up and is full of water, and even then it would be negligable.Dont worry!

HoneySuckleDreams Posted November 15, 2006 Share Posted November 15, 2006 Thanks for that. Yes, I've got all the pipes (and coudes... and the rest) as i'm also making provision for future bathrooms (in my dreams anyway). The reason I asked about gluing is that I heard you might have to heat seal them. I would have thought that this would give the same problems as gluing though. I'll leave everything "dry" i.e. pushed together and get the SPANC man to advise if there are any issues with it all after Fosse bloke has finished.

Alane Posted November 15, 2006 Share Posted November 15, 2006 I was just wondering why it is forbidden to glue the pipe? I've only seen the glue fitting type pipes in our builders merchant - are the collars something that must be purchased separately? Link to comment Share on other sites More sharing options...
HoneySuckleDreams Posted November 15, 2006 Share Posted November 15, 2006 apparently, if you cover the pipes with gravel/earth, they could shift and the glue crack. We also live in an area of seismic activity...although the earth has yet to move for me! The pipes you buy are normally 4m long and are "flanged" at one end so one pipe fits into the next.

fulcrum Posted November 15, 2006 Share Posted November 15, 2006 I have fitted grey plastic 100mm pipe in my house over a ten meter distance, between my loo and the main sewer connection, and I have glued them. Why does a fosse have a different set of rules? My brother in UK did advise me that he thought that soil pipes for Europe, that are to be fitted underground, are a brown colour and have rubber seals. However nowhere in France, that I have seen, do they sell brown plastic piping and or with rubber seals. Link to comment Share on other sites More sharing options...
tj Posted November 15, 2006 Share Posted November 15, 2006 [quote user="Alane"] I've only seen the glue fitting type pipes in our builders merchant - are the collars something that must be purchased separately?[/quote]HiIts just a length of pipe and at one end it is a little wider so you can connect the other piece into it. All the Brico places sell it, and of course the pro merchants. Link to comment Share on other sites More sharing options...
Gyn_Paul Posted November 15, 2006 Share Posted November 15, 2006 Wow ! This is the first I've heard of not gluing 100 pipework. I've just bought 10 x 4m length of it to start on the bathrooms so it will be used both int. and ext.How/why exactly would a friction fit (of the collared pipes) be regarded as a better bet than a glued one ?p Link to comment Share on other sites More sharing options...

Alane Posted November 16, 2006 Share Posted November 16, 2006 TJ Thanks for the info- I've only ever seen one type of 100mm and 125mm pipe in the brico sheds and in the Brico Depot catalogue so I'll make sure I get the right type. Link to comment Share on other sites More sharing options...
Pierre ZFP Posted November 16, 2006 Share Posted November 16, 2006 Can I just point out one thing lest you come unstuck (pun intended)Always ask for 'Tube' as in 'tube d'evacuation' as 'Pipe' means something else entirely.I ask the girl at my local Brico if she could give me some big pipes, and could I have a discount too!! - she nearly fainted while the guy at the counter fell about laughing.It wasn't untill I recounted this to someone I knew who lived in Paris for many years that I discovered my error, talk about an innocent abroad.

All the 100mm tubes I've seen are grey glueable ones, whether they have a collar or not. Can you please give a link or name a brico or show a picture.Thanks.

HoneySuckleDreams Posted November 16, 2006 Share Posted November 16, 2006 Inside the house you can glue, underground you can't (in Dept 65 anyway), you can glue up to the point it goes underground. Liquid gunk might not leak, but the smelly gas stuff might. Suck it and see I suppose. I hate gluing the stuff as it means you have to throw it all away when you need to change things around. Another of the "lets keep people in business" ideas that seem to be common over here. I hopefully brought a load of my rubber sealed push on stuff from the UK that I had lying around... none of it is compatable.. ho hum. Fossy Blokey is turning up next week so I will see what he does and keep you posted. Flucrum... they do have some "joining" pieces with rubber seals to allow to fix broken pipes, but they are only about 20cms long and rather expensive.

littlemouse Posted November 16, 2006 Share Posted November 16, 2006 do you mean the pipes that make up the drainage field ,which are perforated, are not glued or do you mean the solid pipes that make up the evacuation up to the fosse are not glued Link to comment Share on other sites More sharing options...
HoneySuckleDreams Posted November 16, 2006 Share Posted November 16, 2006 any solid pipes underground from the house to the fosse are not glued. The stuff in the drainage field is never glued. Link to comment Share on other sites More sharing options...
tj Posted November 17, 2006 Share Posted November 17, 2006 [quote user="crazyfrog"]any solid pipes underground from the house to the fosse are not glued. The stuff in the drainage field is never glued.[/quote]HiJust to try and clarify in simple terms, the grey PVC pipe you use inside the house is bracketed to the wall, floor etc, the glued joints are not under usual circumstance, prone to any movement. Underground is a different story, so you need to use connectors with the rubber gasket on the inside, or lengths of pipe with the gasket at one end and slot each length into the other.The idea being that the rubber gasket allows for some limited movement should the ground be subject to any movement, tremors etc. The key is of course in the proper installation within the trench in the first instance, and there is lots of information on the net, take a look at the http://www.planningportal.gov.uk/england/professionals/en/1115314110382.html "Part H" this is of course UK regs so you wont go far wrong.

The flexible rubber manchon would take the strain. Link to comment Share on other sites More sharing options...
