Weld joint issues


Pocster

Recommended Posts

Well !

 

After a struggle I re designed how I would do this so I could glue 1 part as I go . Deliberately allowing for 1 easy joint at the end . Marked with tape depth for each fitting and then a biro mark to ensure line up . Was a right PITA !

 

But now done ! ( unless it leaks ) 

Just need @Big Jimbo to say “ looks like a brilliant job “ to make my life complete !

Will take advice on a boss strap for AAV - but it would be before this wc ( rather than after I.e the last thing on the soil run )


It has to be outside of a specific distance from a  WC entry - it is in the regs

Erm ! Ok that’s not a problem if I move along my soil pipe I.e away from this wc .

Which regs ? I’ve not seen that mentioned before .

So is it critical ( or not ) that it’s not at the end of the soil pipe ?

Part H

Min 200mm from memory but I would check. Also worth trying to get a strap boss in the top half of a horizontal run

 

 

Yes 200mm . 
Thicker white pipe is AAV 
So this type of arrangement ?

Or is this better ? AAV pipe with pink arrow . Boss strap straight off WC waste - still over 200mm from pan exit

step away from the flexi...

 

90 degree elbow on the horizontal then use an 11/22  degree single socket to align to the bottom pipe.
 

Hope you can lift that vertical pipe though ....

I did guess flexi was bad !!!

?
 

In 110mm soil weld I can find 90 , 135  but no 11/22 socket thingy .

Look for 112.5 (22.5) 

 

In reality I wouldn’t have done it like that and having soil pipes do a 90 degree tee is not ideal. I would have used a Y junction further down the flow, and then used a standard swept elbow at the bottom of the vertical to direct it across at 45 degrees to the main flow. 
 

I would also be securing the horizontal flow much better as a vertical drop will bounce that joint hard and you need to strap it tight up against the elbow.

Hmmm yes . I was taking short route method - but take your point .

Still can’t find 112.5 soil weld - I must be looking wrong 

 

intend to add support later anyway
