jamiehamy Posted May 16, 2017 Share Posted May 16, 2017 Hi all, I've taken delivery of the taps and shower kit for out en-suite and now planning the install for this. Both the shower valve and the taps (double sink) are 'concealed'. Whilst I understand the principles of what I'm aiming to do, I've not managed to find any particularly helpful videos online - they all seem a bit generic of half hearted! So my ask is 1 can someone point me to a good video for this please! and 2 - looking for hints and tips to make this a bit easier. For this one, we are fitting to a 150mm stud wall. Thanks!

PeterW Posted May 16, 2017 Share Posted May 16, 2017 Any chance of knowing which ones as that makes a difference... Grohe have their own way, as do others Link to comment Share on other sites More sharing options...
jamiehamy Posted May 16, 2017 Author Share Posted May 16, 2017 Sure - Lusso Mia shower set and tap. The instructions are fairly useless tbh! https://www.lussostone.com/taps-c3/basin-taps-c8/lusso-mia-series-wall-mounted-basin-mixer-tap-matte-black-p549 and the Mia Shower set.

Barney12 Posted May 16, 2017 Share Posted May 16, 2017 I'm not helping your thread but those matt black taps are striking. Ill be interest to know if they show water marks/droplets/spray easily meaning constant cleaning to keep then looking as stunning as they are?

jamiehamy Posted May 16, 2017 Author Share Posted May 16, 2017 (edited) So to be a bit more helpful, looking for thoughts on following on the shower first as that seems the most straight forward having looked at it. I have access to the rear of the stud wall (it's a column) and the sides of the studs on either side, so my thinking is that I can do all this 'from behind'. PLanning putting a 150mm dwang across screwed on either side to mount the valve (screwed rather than nailed to ensure no movement). I will mark and cut the holes on the tiled side first, fit the valve to the dwang and position in, then afix the dwang at the appropriate depth. I can then do the plumbing 'in situ' fro behind, test then fit the gyproc. For the connections, there are two 1/2" female and 3/4" females, so will these be appropriate to transition to 15mm (plastic) supply pipe work?http://www.screwfix.com/p/pegler-male-taper-15mm-x/7866g Finally, for the run up to the shower head and the hand held, is there any reason I can't do plastic for these? Thank you kindly! Jamie Edited May 16, 2017 by jamiehamy Link to comment Share on other sites More sharing options...

In the interest of convenience and not being very clued up on bathroom furniture ranges, we visited Bathstore and ordered everything from them. Long story short - a lot of faffing happened and my other half started looking at other things - and discovered Lusso. Before we knew it, all we are getting from Bathstore is a shower and a tap..which is a shame because they were very helpful - until someone left, someone died and someone broke their ankle...! We're getting most stuff from Lusso and Bauhaus now. Link to comment Share on other sites More sharing options...
RandAbuild Posted May 16, 2017 Share Posted May 16, 2017 Funnily enough, I've just done this last week - added 2 dwangs from the other side of a stud wall to provide a hand shower attachment and rain head to the shower. On the shower side, I added a sheet of ply before the blue plasterboard (we needed to pack out this wall to avoid a floor joist fouling the shower drain; it's also better for hanging a wall-hung double sink from!). This extra depth meant the usual wall plate elbow ( http://www.screwfix.com/p/p803wp-2-wall-plate-elbow-15mm-x/92934 ) wouldn't be long enough, so I added a female coupler ( http://www.screwfix.com/p/female-coupler-15mm-x/93992 ). All this was done from the other side of the wall, and I screwed the assembly to a piece of ply before adding the dwang so it would all line up: Link to comment Share on other sites More sharing options...

Temp Posted May 17, 2017 Share Posted May 17, 2017 One problem seems to be fitting the bright work (eg spouts) to elbows. There seems to be no certain way to end up with the connection tight and pointing in the right direction. When we did ours up they sometimes went 45 degrees past the right position before I felt they were tight enough. Solution seems to be to undo it, add even more PTFE tape and try again. Hate bodges like that. Link to comment Share on other sites More sharing options...

Hate bodges like that. I don't know if it would be applicable, but when I faced this issue installing valves on a boat, the advice was to use liquid PTFE and a backnut, allowing you to lock the fitting in place at whichiever orientation you needed. Requires sufficient threaded length to fit the extra nut, though. Link to comment Share on other sites More sharing options...

I'm down south without proper computer access - for some other the other bathrooms I might be easier with a 90degree elbow coming out but I suppose I can use this then a 90 or 45 degree elbow. Will be the same difference. Hugely helpful responses from everyone, thank you! Link to comment Share on other sites More sharing options...

This is on the manifold tho so committed to a compression elbow with male connector. Everything else is perfect just this one. Link to comment Share on other sites More sharing options...

If it's the BSP male fitting that is loose then buy a decent U.K. branded one such as Pegler and see if that has any less slop. If there is still slop then consider sending the shower valve back as it's out of tolerance. The other choice is to go for a plastic elbow such as a Hep2O one as I've found they tend to seal a bit better than brass on brass Link to comment Share on other sites More sharing options...
jamiehamy Posted June 23, 2017 Author Share Posted June 23, 2017 So this is for the manifold (I'm using the connector posted above for the shower valve). The manifold ports are pointing down which means the male elbow still has around half a turn left to tight - which would have it pointing the wrong way. I'll try more tape first, I've probably been a bit sparing and the Loctite stuff if that fails. The other two are fine, just this one weeps slightly.

This is exactly how I had to do ours on our last house, square tap spout, asked the plumber who did the first fix and he said that is just how they are, take it off add a new piece of tape and re instal, I agree I doesn't seem right I even split a tap spout as I forced it around into the right position.

Russell griffiths Posted June 23, 2017 Share Posted June 23, 2017 On a hotel water system we did every threaded joint had a liquid thread lock compound on it, after hundreds of joints I don't remember having 1 single weap anywhere could be worth having a hunt around for a liquid sealer.

I've used Screwfix Liquid PTFE a lot, and it's never yet failed. The dispenser bottle is a really bad design, making it frustrating to get the stuff out, but it works really well. If a joint needs to be undone, then gently warming it up will soften the sealant and allow it to unscrew fairly easily. Link to comment Share on other sites More sharing options...

Ended up keeping it upside down when I used it as the dispenser is so poor. Sets rock hard. I wouldn't use again unless I absolutely had to. Tbh on a compression / threaded fitting Jet Blue Plus is fantastic and it's my go to for anything like this. I can't praise it enough. Stops compression fittings squealing as you do them up and forms a demountable seal. It just seems to lube the joint up and make it go "better". Expensive mind: http://www.plumbcenter.co.uk/product/center-center-jet-blue-plus-500-g/ EDIT: Jet Blue Plus cured a leak on 9bar incoming main. Used it further to @Nickfromwales's suggestion though he favours something else similar. Edited June 23, 2017 by Onoff Link to comment Share on other sites More sharing options...
