new-bathroom-suiteInstalling a new kitchen or bathroom, with all the relevant fixtures and fittings, requires a certain amount of skill with plumbing and electricity. There will probably be some areas where you need to seek professional advice, but as far as the basic tasks are concerned, most jobs are relatively straightforward as long as the correct order of work is followed and the appropriate techniques used. This post shows the best techniques for installing a selection of fittings. Be sure to plan jobs thoroughly so that you can have all the right connections for a particular installation before you start.

Preparing Plumbing And Electrics

When new fittings are to be positioned in a different place from the old ones, you will need to reroute supplies. It is therefore important to have some understanding of the various types of pipe available and the various ways in which they can be joined. Before embarking on any pipework, always turn off the water supply and drain the pipes. Regarding electrical supplies, major overhauls are not usually required, although some cables may need rerouting.

Cutting Copper Pipes

Clamp the pipe cutter around the pipe and rotate it in the direction designated by the arrow until it cuts all the way through. You can use a hacksaw to cut the pipe if you wish, but the pipe cutter gives a cleaner cut.
Clean the pipe using wire wool before making any connections.

Connecting copper pipes

There are several ways of making a connection or joint between copper pipes. The simplest is to insert a compression joint. However, it may be unsightly if it is in a position that can be easily viewed. The other methods involve using solder and the gas torch. They are slightly harder to produce a neater finish.

Compression Joints

compression joints are easy to fit because the process does not require the use of a gas torch.
Separate the compression fitting and slip it into place on the two ends of the cup pipe. To begin with, position it hand tight with the olives (small rings) situated on the pipe inside the fitting.
2 use adjustable spanners to tighten the joint, allowing the threaded section to tighten onto the olives to create a watertight seal.

Soldering Ring Joints

Soldering joints are the easiest type of joint to make because the solder itself is already inside the connector.

  1. Apply flux to the ends of the pipes and inside the connector. The flux helps to clean the copper and achieve a watertight joint.
  2. Slot both ends of the pipe into the connector. Holding the pipe over a heat resistant mat, use a gas torch to heat the joint gently, allowing the solder to ring inside to melt and form a watertight seal.

Safety advice
When using a gas torch, always read the manufacturers guidance to ensure safe use. Gas torches should never be left burning unattended, and a heat resistant mat should be positioned next to the joint to avoid burning or singeing adjacent surfaces.

End feed joints

The other type of solder joint is referred to as the end feed joint. It does not contain a ring of solder inside and, therefore, the solder must be applied during the heating procedure with the gas torch. Flux is still used to clean paper ends, but solder wire must be applied around the joint to create a watertight seal.

Connecting plastic pipes

Plastic pipes are usually very easy to connect since many have push fit joints or are threaded with rubber washers. However, in some cases, solvent weld joints have to be formed using a special type of cement to fix the pipes together.

  1. Cut the pipes to the required size with a hacksaw or handsaw and clean the ends thoroughly.
  2. Apply solvent weld cement around the end of the tube. Push the end of the pipe into the required connector. Remove excess cement with a cloth and allow the joint to dry before continuing.

Electrical Rerouting

In hollow walls or ceiling voids, cables can be fed into place, but with solid walls, the procedure is more laborious. Leave the actual electrical work, such as wiring to professionals.

  1. Draw pencil guidelines where the cable will run. Use a club hammer and a bolster chisel to cut through the wall, removing material to a depth of around 2.5 cm.
  2. Position the cable well below the surface level. Cover it with an impact resistant plastic channel held in place with galvanised nails, then apply a surface finish such as plaster.
