I wonder if just really roughing up the meltable and non meltable surfaces will work with the solvent / gap filling solvent? Link to comment Share on other sites More sharing options...
Onoff Posted August 26, 2017 Author Share Posted August 26, 2017 Expecting to be going the adapter route I tried chamfering the inside of the Geberit pipe with a Stanley then some 80 grit paper. Looks worse in the photo but this won't be too rough will it? Holding off on this until I figure the elbow detail. Link to comment Share on other sites More sharing options...
Nickfromwales Posted August 26, 2017 Share Posted August 26, 2017 Have you bought a compression fitting and tried the two together? Compression are on every shower, bath and wash basin, kitchen sink, and more, across the whole EU, and I've taken out ones that have been in for 30 years with no leaks. . It's not the fitting to fear, it's the fitter. I'd use compression in a heartbeat as they're very, very reliable. A bit of silicone grease and just a bit over hand tight. Better than a medley of plastics which don't like each other, brought together by fittings that don't relate . Link to comment Share on other sites More sharing options...

The McAlpine compression straight coupler that came in the box is different sized each end but both around 50mm. Photos to follow. I'll get an elbow like it hopefully. If I'd have read this earlier I could have finished it..... McAlpine do a 2" multi fit I see. Can't see me getting one at any of the sheds this weekend though.

Onoff Posted August 26, 2017 Author Share Posted August 26, 2017 Dispensed with the idea of EPS behind the drain, it would have had to taper anyway. Spray glued the wall DPM to the black painted wall. Loaded the black painted wall with Soudal foam and folded the floor DPM up against it. Then put the wall drain against the DPM and temporarily wedged/screwed in place. Will cut flush when dry. Then I'll remove the drain, sort the studwork and drill through the wall etc: Link to comment Share on other sites More sharing options...
Nickfromwales Posted August 27, 2017 Share Posted August 27, 2017 That's better TBH. Fully filled now so can't improve on that. . Keep going, you're setting a pace now Link to comment Share on other sites More sharing options...
Onoff Posted August 27, 2017 Author Share Posted August 27, 2017 (edited) Didn't come out too bad, bit of a crease and a bit of a hollow by the feel of it along the mid-line but then it was quite thick and deep to do in one go. When "in" I'll poke the foam fun nozzle down thru the set foam and fill a bit more. I'm going to follow @Nickfromwales's advice and go with silicon lubed compression fitting. Going to use the straight coupler that came with it but cut back the Geberit black pipe to get it all in. Going to go with the tight 90 and keep telling myself it's 50mm and it'll cope!

Onoff Posted August 27, 2017 Author Share Posted August 27, 2017 Cut down the Geberit pipe, slipped on the fitting with a bit of silcon grease. SHOULD have left it a bit longer then it would have slipped inside the larger (black) pipe shown here by an offcut. Link to comment Share on other sites More sharing options...
Nickfromwales Posted August 27, 2017 Share Posted August 27, 2017 40mm would do it, 50mm is for the sake of being able to fit it. 50mm guarantees an air break even with the soapiest of suds going down't plug'ol. Link to comment Share on other sites More sharing options...

I just had to "borrow" the length of external 50mm waste to the bath (just in temporarily to the drain) to get a bit for going thru the wall to the shower. AMAZED that it is spotless and then some inside. It's had a load of soapy, bath bombs included baths through it. Good call on 50mm way back, have you done this before?

Onoff Posted August 27, 2017 Author Share Posted August 27, 2017 Well drilling that hole was a mission! My Makita SDS threw a hissy fit (clutch?). Off the nephew's to borrow his, don't laugh, Guild brand SDS he got from Homebase for about £20 on clearance. I was actually well impressed with it. (In Argos for £60 still). THEN my SDS drill bit sheared off in HIS drill! Had to strip that down and remove the offending bits! Start again! Got some patching of the DPM to do. With the Polypipe panels mesh and UFH pipes it was a bit of a pig so the holes a tad steep and a bit oval vertically. A bit of re-drilling and better now: Bits solvent welded together: The "hollow" where I'd foamed behind the DPM was in fact still wet foam so when I took the wall drain off to do the pipe it proceeded to expand to the point I couldn't get the drain back in position! Peeled off the DPM and now waiting for it to all fully expand before trimming again: Tided up and went and played under the mower with the lad for a bit. Cutting deck off new belt half on. Beer o'clock now. Link to comment Share on other sites More sharing options...

Upstairs bathroom, lounge/diner knock through, dormer roof, main roof, stable block......etc. Got another 10 rooms/areas at least that need the "treament" then there's the outside! I'll be around here for a while I reckon. Link to comment Share on other sites More sharing options...

I've found spraying water first and then foaming slowly allows it to expand fully. Hope I'm not teaching Granny to suck eggs. Link to comment Share on other sites More sharing options...

I literally foamed the wall then "hinged" the cut DPM back up and bolted the Geberit drain in place. I'm sure it would've been OK but I took it off the next day as said. Weird how it remained "liquid" in there though. Maybe taking the drain off allowed air to seep in? I did have a couple of the wife's plastic plant sprayers in there but she keeps taking them back!

Onoff Posted August 28, 2017 Author Share Posted August 28, 2017 (edited) The foam's trimmed back albeit with some nice hollows. I won't put any more foam on until the drain ain't coming out again! Got to make good the DPM. This is the one atop the EPS layer. I reckon just a line of CT1 as I put the drain in: The other side: Tbh as long as I keep the external wall / DPC clear (it was all covered previously by render and a high path) I don't think bridging i.e. horizontally penetrating damp will be an issue and anything "running" should still stay outside the DPM. Fingers crossed! Edited August 28, 2017 by Onoff Link to comment Share on other sites More sharing options...
Onoff Posted August 28, 2017 Author Share Posted August 28, 2017 (edited) In & done. I'll cap the end outside and see if it leaks. Taking my chances with the DPM repair: Outside to do too, hope that shower waste isn't too steep: Just had a beer to fortify myself, shower tray former now!

Nickfromwales Posted August 28, 2017 Share Posted August 28, 2017 Not too steep imo. Is it going into a gulley or a boss on the stack ? Link to comment Share on other sites More sharing options...

Gulley/grate I think where the existing one is between the black 50mm in the foreground (bath) and the new shower one about equi-distant beyond the drain. I'm going to redo it anyway and get rid of the old clay. Probably lower it too. The white monstrosity coming round the corner is from the upstairs ensuite. Trying to avoid bathroom grey water going directly into soil stacks in case the cess pit backs up! Link to comment Share on other sites More sharing options...
