How to Fit Bar Mixer Shower Pipework
This post describes how to 1st fix pipework for a bar mixer shower valve installation.
When setting up a bar mixer shower valve such as the one revealed, it is initially essential to run hot and cold pipework to the valve.

Please see Choosing a shower for your bathroom to find out more on shower types and their viability for your restroom.
This is done by recessing the pipes within the wall prior to tiling.
In this case research study I will be recessing the pipework into a restroom wall that has actually currently been dot n dabbed with moisture resistant plasterboard.
Doing the plaster-boarding before the 1st repair pipework makes it simpler to get completely flat & level walls as you do not have the fiddly task of attempting to fit the boards around/ over the pipework (among other things.).
Walls also require to be square in the corners to permit a great seal (along the edge of the bath in this instance.).
Please see Preparing walls for tiling-- reboarding for more details relating to this topic.
Utilizing Bath to Mark Overflow/Waste and Center of Bath Taps.
The bath is temporarily put in position, and the centre line (that goes through the overflow/ waste and the centre of the bath taps) is marked.
This will help us line the shower valve up with the taps for a more visually pleasing surface.
The horizontal level of the bar mixer shower valve is then significant, which is normally around 130cm from the flooring. If you are meaning to fit a bar mixer shower with a fixed riser and shower head, you will require to guarantee that this height allows you to fit the shower in without it striking the ceiling.
Correct Shower HeightIncorrect Shower Height.
Next the pipeline centres are marked with vertical lines at 150mm centres i.e. 75mm far from the centre line in both instructions. This is where the pipework will run from the valve, down the wall and link to the pipework under the bath.
A lot of bar mixer shower valves accept pipework at 150mm centres as this is considered standard-- if your particular model has a different pipeline centre worth, then you need to show this at the marking out phase.
A location to be chased out is then significant (into which the pipes can be recessed beneith the surface of the plasterboard.).
The approximate height of the bath rim is likewise marked at this stage.
Correct Shower Height.
The locations to be chased after out are then chased out using a precise saw, ensuring that they extend below the level of the bath rim, which is marked in pencil on the plasterboard.
Here we can see the pipework under the bath that will be extended approximately feed the shower valve.
The hot feed will be run up the left hand channel, and the cold feed will be added the right-hand man channel.
This is because the hot feed will enter the valve left wing (as we take a look at it) and the cold feed upon the right.
This is an industry requirement.
Since of this, the pipework under the bath is in line with this configuration.
You can see that the bath drain & trap has actually likewise been fitted at this time. When the bath was in position, a cross was marked on the flooring through the waste hole in the bottom of the bath to mark the essential place of the bath trap.
Copper Pipework Is Soldered And Then Placed Into The Channels.
2 pieces of 15mm copper pipework are then soldered together with a 90º elbow for each feed, which are then put into the channels as shown.
The horizontal pieces of copper (at the top) will eventually be reduced to go into the back of the bar mixer valve.
The pipes are held level and square to the wall at 150mm centres (centred on the preliminary centre line) by a home-made jig which is screwed to the wall momentarily. This is necessary as attaching the shower valve counts on this phase of the work being done accurately:.
Pipes Are Held Level And Square To The Wall.
It is essential the the pipes are recessed far enough into the wall so that the 90º elbow fitting does not protrude out beyond the ended up tiled surface.
This will ensure that it does not interfere with the fitting of the bar mixer shower valve.
Inaccurate Shower PipeworkCorrect Shower Pipework.
The pipes are then protected in place by using either drywall adhesive, rapidset tile adhesive or a sand-cement mix.
If utilizing a mix consisting of cement, please ensure the pipes are wrapped in duct tape to prevent the cement from attacking the copper which might lead to pinholes and leakages establishing in time.
The mix is pressed in and around the pipes and is utilized to support the cut edges of the plasterboard.
Mix Is Levelled Off Flush With Surface of Plasterboard.
This is then levelled off flush with the surface area of the plasterboard, guaranteeing access to the bottom of the pipes is exposed so that they can be linked up later on.
Batons are screwed and glued to both walls surrounding the bath, and these will assist to take the weight of the bath when it has plenty of water and/or residents. This will avoid it from dropping, which can lead to damaged silicon seals and water ingress issues.
Briefly Position The Bath to Allow For The Pipework To Be Connected.
The bath is then momentarily positioned in position to allow for the pipework to be connected.
The existing hot and cold pipework is connected to the proper pipework in the wall that will feed the shower valve.
Arrangements are likewise made at this stage to connect the bath taps-- through versatile push fit tap adapters in this circumstances.
Jig Is Removed And Voids Are Filled With Adhesive.
As soon as the adhesive holding the pipes has gone off and the pipes are safely held in the right position, the jig can be eliminated and any staying voids filled in with more adhesive.
As the pipework is now linked to the hot and cold provided, stop ends can be seen in place at the ends of the pipes.
The bath is now be set up, and you can see the primary silicon seal around the edge of the bath in this photo.
Tanking And Tiling The Walls.
The walls are then tanked and tiled.
