How to Fit Bar Mixer Shower Pipework

This post discusses how to 1st fix pipework for a bar mixer shower valve installation.

Intro

When installing a bar mixer shower valve such as the one revealed, it is initially needed to run hot and cold pipework to the valve.

Please see Choosing a shower for your restroom for more information 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 bathroom wall that has actually already been dot n dabbed with moisture resistant plasterboard.

Doing the plaster-boarding prior to the 1st fix pipework makes it much easier to get completely flat & level walls as you do not have the fiddly job of attempting to fit the boards around/ over the pipework (to name a few things.).

Walls likewise require to be square in the corners to permit a good seal (along the edge of the bath in this instance.).

Please see Preparing walls for tiling-- reboarding for additional information connecting to this topic.

Method.

Using Bath to Mark Overflow/Waste and Center of Bath Taps.

The bath is temporarily placed 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 aesthetically pleasing surface.

The horizontal level of the bar mixer shower valve is then marked, which is typically around 130cm from the flooring. If you are planning to fit a bar mixer shower with a fixed riser and shower head, you will need to make sure that this height enables you to fit the shower in without it striking the ceiling.

Next the pipeline centres are marked with vertical lines at 150mm centres i.e. 75mm far from the centre line in both directions. 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 thought about basic-- if your specific model has a various pipeline centre worth, then you need to reflect this at the defining stage.

An area to be gone after out is then significant (into which the pipes can be recessed beneith the surface area of the plasterboard.).

The approximate height of the bath rim is likewise marked at this stage.

Correct Shower Height.

The areas to be chased out are then chased out using a specific 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 added the right hand channel.

This is since the hot feed will enter the valve on the left (as we take a look at it) and the cold feed on the right.

This is a market standard.

Since of this, the pipework under the bath is in line with this setup.

You can see that the bath waste pipe & 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 essential location 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 cut down 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 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 necessary the the pipes are recessed far enough into the wall so that the 90º elbow fitting does not extend out beyond the ended up tiled surface.

This will make sure 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 utilizing either drywall adhesive, rapidset tile adhesive or a sand-cement mix.

If using a mix containing cement, please guarantee the pipes are wrapped in duct tape to prevent the cement from assaulting the copper which could result in pinholes and leaks 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 area of the plasterboard, ensuring access to the bottom of the pipes is left open so that they can be connected up later.

Batons are screwed and glued to both walls bordering the bath, and these will assist to take the weight of the bath when it has plenty of water and/or occupants. This will avoid it from dropping, which can lead to broken silicon seals and water ingress problems.

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 connected.

The existing hot and cold pipework is connected to the appropriate pipework in the wall that will http://elliottheet124.tearosediner.net/12-steps-to-finding-the-perfect-plumber-in-glasgow feed the shower valve.

Arrangements are likewise made at this stage to link the bath taps-- by means of flexible push fit tap ports in this instance.

Just like the shower valve, hot is on the left and cold on the right (as you look at the tap) so this makes pipework simpler.

Jig Is Removed And Voids Are Filled With Adhesive.

When the adhesive holding the pipes has gone off and the pipes are firmly kept in the proper 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 supplied, stop ends can be seen in location at the ends of the pipes.

The bath is now be installed, and you can see the primary silicon seal around the edge of the bath in this picture.

Tanking And Tiling The Walls.

The walls are then tanked and tiled.
