Hello All
Anyone have any tips for half burying a 32mm waste elbow in a brick wall so that the pipe emerges from close to flush to the wall?
I can get the fitting in but if I went to glue it up the brush and fitting would get brick dust all over it. Do I need to drill the opening a lot bigger then make good with mortar maybe? How big? Or could I PVA the opening to stop dust getting on the glue?
What is the normal way to do it ?
Thanks a lot in advance.

my tip is, glue the elbow on first onto two lenghts of pipe, one long enough to reach the appliance and the other long enough to reach its first bend on the outside, then shove it in wall and clip the outside so it won't move as you work inside connecting it to the appliance,  |

Same as Tom and Rocky.
I try to keep the pointing to an minimum cause the owners house dragon always complains it doesn't match the existing cement colour!

Right, firstly thanks a lot for replies so far and make a lot of sense.
I'm gonna stick my head above the parapet so to speak and show what a really crap DIY bodge I've currently got. I have to show it though to get any ideas.
The "room" is between house and garage and is covered but is basically an extension of the garage so things don't need to be too pretty. The pipe going across in front is a 32mm from a basin and the 40mm behind is from the shower. The pipe on the left is a 50mm and runs along the house wall and then goes inside to the stack. The bathroom these come from are actually through the wall on the right which is the garage and then above that.
I'm thinking to connect the 32 into the 40 so at least there is then only one pipe left going across this passage. But without a slip coupling I can't see how to do it ??
The pipes as is do drain very well from a powerful shower and there are no traps getting sucked out but its really not pretty. I'd obvisouly rather not have to redesign the route all from scratch so hoping connecting the 32 into the 40 is enough (?) but not sure how to do it.
Second pic is from inside the garage where they then go up into the shower room.
P.S. The 32 pipe is slightly higher than the 40 in the corridor.
Sorry for so much text !!

ok so if I'm reading this right, there are two appliances going to into a 40mm pipe and thats going to the outside, So I'd still do the same, make the elbow going through the wall up and glued, then join it inside with a coupling to the straight 40mm pipe,

might be outside the box thinking but if it works ok and its only cosmetic have you considered a false ceiling ?

Right instead of all the text above I should have labelled my photo which I've done. Red is existing, green is proposed.
What I really can't get into my thick head is how to get in that new 32mm green pipe. I could glue on a new tee and push the pipe in but then there'd be a gap in the 40mm.
Thanks again for taking the time to understand this. What a dog's breakfast !

Well I suppose it was a big ask to hope someone would design my pipework for me. I've always struggled with connecting up new pipework so I don't need slip connectors. Definitely grateful for the tip about glueing first then pushing into the wall so I'll try an incorporate that into my plan.

Can't you get rid of the external 32mm completely?
Elbow the 32mm inside and go into a tee on the 40mm pipe with a 40/32 reducer. Looks tight but could sort you out. As you say the 32 mm is slightly higher then all's good.

Just to confirm I've uploaded the pic from inside the garage but proposal. Only slightly down point is that I only added that lever valve and 15mm branch a few days ago - would have to redo it but shouldn't take that long I suppose. I like your website by the way - some nice work there ! |

Yeah, that's exactly what I was suggesting. As long as the new tee will fit in there it should look a lot better. As for the lever valve, you might get away with it, but personally I'd lower that run a bit for access in future. Thanks for the compliment, I made that website myself, costs £16 a year to run it  |

Well mostly thanks to JC I've got things looking a lot better. I had to do some work anyway because I needed to hide the 32mm pipe in a stud wall above but I'm very happy I've made them look a lot better than before. The only slight annoyance is the 50mm isn't now 100% straight but there is play in the pipe and I could just raise the last bracket a little but not sure I can be bothered - it doesn't look that obvious in reality. Oh, and being a Dafty, of course one of my fking connectors leaked 1st time round. It was the access/rodding point into the 32mm tee in the garage. I used Floplast and I swear there was a huge amount of play with that AP and the tee before I glued it in. Fixed it by unscrewing the cap and working in a load of solvent glue both inside and out. On solvent weld, its said the pros prefer it because they "never leak" but I'd say about 1 in 20 of my joints always fking leak. I wonder if I'm not using enough glue? The Floplast glue brush doesn't go anywhere near the bottom of the bottle which doesn't help and if you use another brush its history the next day. I'm definitely doing something wrong. Anyway, all done now (apart from the copper pipework) and very pleased. Thanks again to jcplumb and others for help. |
