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 setting up a bar mixer shower valve such as the one revealed, it is first necessary to run hot and cold pipework to the valve.
Installing a Bar Mixer Shower Valve
Please see Choosing a shower for your restroom to find out more on shower types and their suitability 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 currently been dot n dabbed with wetness resistant plasterboard.
Doing the plaster-boarding prior to the 1st fix pipework makes it easier to get completely flat & level walls as you do not have the fiddly task of trying to fit the boards around/ over the pipework (among other things.).
Walls likewise need to be square in the corners to allow a great seal (along the edge of the bath in this instance.).
Please see Preparing walls for tiling-- reboarding for more details associating with this subject.
Approach.
Utilizing Bath to Mark Overflow/Waste and Center of Bath Taps.
The bath is briefly placed 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 visually pleasing finish.
The horizontal level of the bar mixer shower valve is then significant, which is normally around 130cm from the floor. If you are meaning to fit a bar mixer shower with a fixed riser and shower head, you will need to make sure that http://jareddvyw520.trexgame.net/the-3-greatest-moments-in-local-plumber-glasgow-history this height enables you to fit the shower in without it hitting 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.
The majority of bar mixer shower valves accept pipework at 150mm centres as this is considered standard-- if your particular model has a various pipe centre worth, then you require to show this at the defining phase.
A location to be gone after out is then marked (into which the pipes can be recessed beneith the surface area of the plasterboard.).
The approximate height of the bath rim is also marked at this phase.
Correct Shower Height.
The locations to be gone after out are then chased out using a specific saw, making sure 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 added the right hand channel.
This is because the hot feed will get in the valve left wing (as we take a look at it) and the cold eat the right.
This is a market standard.
Due to the fact that of this, the pipework under the bath remains 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 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 placed into the channels as revealed.
The horizontal pieces of copper (at the top) will become 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 initial centre line) by a home-made jig which is screwed to the wall briefly. This is necessary as connecting the shower valve depends on this stage of the work being done accurately:.
Pipes Are Held Level And Square To The Wall.
It is necessary the the pipes are recessed far enough into the wall so that the 90º elbow fitting does not protrude out beyond the finished tiled surface.
This will guarantee that it does not interfere with the fitting of the bar mixer shower valve.
Inaccurate Shower PipeworkCorrect Shower Pipework.
The pipes are then secured in location by utilizing either drywall adhesive, rapidset tile adhesive or a sand-cement mix.
If utilizing a mix containing cement, please make sure the pipes are wrapped in duct tape to prevent the cement from assaulting the copper which might lead to pinholes and leaks developing over time.
The mix is pushed in and around the pipes and is used 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, ensuring 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 bordering the bath, and these will help to take the weight of the bath when it is full of water and/or occupants. This will avoid it from dropping, which can result in damaged silicon seals and water ingress issues.
Briefly Position The Bath to Allow For The Pipework To Be Connected.
The bath is then momentarily put in position to permit the pipework to be connected.
The existing cold and hot pipework is linked to the suitable pipework in the wall that will feed the shower valve.
Provisions are likewise made at this phase to connect the bath taps-- by means of flexible push fit tap ports in this circumstances.
Just like the shower valve, hot is on the left and cold on the right (as you take a look at the tap) so this makes pipework 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 remaining spaces completed with more adhesive.
As the pipework is now linked to the cold and hot supplied, 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 main silicon seal around the edge of the bath in this photo.
Tanking And Tiling The Walls.
The walls are then tanked and tiled.
