How to Fit Bar Mixer Shower Pipework
This short article discusses how to 1st repair pipework for a bar mixer shower valve installation.
Introduction
When installing a bar mixer shower valve such as the one shown, it is initially required to run hot and cold pipework to the valve.

Please see Choosing a shower for your restroom to learn more on shower types and their viability for your bathroom.
This is done by recessing the pipes within the wall prior to tiling.
In this case study I will be recessing the pipework into a restroom wall that has already 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 don't have the fiddly job of trying to fit the boards around/ over the pipework (to name a few things.).
Walls also require to be square in the corners to enable a great seal (along the edge of the bath in this circumstances.).
Please see Preparing walls for tiling-- reboarding for more information relating to this subject.
Technique.
Utilizing Bath to Mark Overflow/Waste and Center of Bath Taps.
The bath is momentarily positioned in position, and the centre line (that runs through the overflow/ waste and the centre of the bath taps) is marked.
This will assist us line the shower valve up with the taps for a more aesthetically pleasing surface.
The horizontal level of the bar mixer shower valve is then significant, which is usually around 130cm from the floor. If you are intending to fit a bar mixer shower with a fixed riser and shower head, you will require to guarantee that this height enables you to fit the shower in without it striking the ceiling.
Correct Shower HeightIncorrect Shower Height.
Next the pipe 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.
Most bar mixer shower valves accept pipework at 150mm centres as this is thought about standard-- if your particular design has a different pipeline centre worth, then you need to reflect this at the marking out stage.
A location to be chased out is then marked (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 gone after out are then gone after out using an exact 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 as much as feed the shower valve.
The hot feed will be added the left hand channel, and the cold feed will be run up 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 standard.
Due to the fact that of this, the pipework under the bath is in line with this setup.
You can see that the bath drain & trap has actually also been fitted at this time. When the bath remained in position, a cross was marked on the floor through the waste hole in the bottom of the bath to mark the needed place of the bath trap.
Copper Pipework Is Soldered And Then Placed Into The Channels.
Two 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 become reduced to enter 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 briefly. This is important as connecting the shower valve depends on this stage of the work being done properly:.
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 area.
This will ensure that it does not interfere with the fitting of the bar mixer shower valve.
Incorrect 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 http://griffinqvns193.lucialpiazzale.com/20-gifts-you-can-give-your-boss-if-they-love-plumber-glasgow-24-7 including cement, please guarantee the pipes are covered in duct tape to prevent the cement from assaulting the copper which could result in pinholes and leakages developing 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 of the plasterboard, making sure access to the bottom of the pipes is left open so that they can be connected up later on.
Batons are screwed and glued to both walls surrounding the bath, and these will help to take the weight of the bath when it is full of water and/or residents. This will avoid it from dropping, which can lead to broken silicon seals and water ingress issues.
Briefly Position The Bath to Allow For The Pipework To Be Connected.
The bath is then momentarily placed in position to enable the pipework to be linked.
The existing cold and hot pipework is connected to the proper pipework in the wall that will feed the shower valve.
Arrangements are likewise made at this stage to link the bath taps-- via flexible push fit tap ports in this circumstances.
As with the shower valve, hot is on the left and cold on the right (as you look at the tap) so this makes pipework much easier.
Jig Is Removed And Voids Are Filled With Adhesive.
As soon as the adhesive holding the pipes has actually gone off and the pipes are firmly kept in the right position, the jig can be gotten rid of and any staying voids completed with more adhesive.
As the pipework is now linked to the cold and hot provided, stop ends can be seen in location at the ends of the pipes.
The bath is now be set up, and you can see the main silicon seal around the edge of the bath in this photo.
Tanking And Tiling The Walls.
The walls are then tanked and tiled.
