Recommended Material for Repiping Plumbing Lines
Some plumbing components age faster than others and your plumbing installation deserves a little regular rejuvenation.
To know the different elements that make it up and understand the differences between materials, discover our article on these elements of plumbing that we use every day.
What are the components of plumbing in a home? What are the materials of a plumbing installation? What are the different plumbing fittings?
The elements of your plumbing installation
You have a nice bathroom where you will have a nice bathroom. The plans are ready, you have visited many showrooms, the style is chosen, you may be mixing wood and porcelain, the deck deck and a baroque atmosphere, in short, a great achievement awaits you.
Your bathroom will look like your idea for a long time and will be more comfortable. So there is what is apparent and that is the look of your bathroom and what is hidden from view: fittings, pipes, tubes, necks ...
The pipes and fittings of your plumbing
Your plumbing system has many pipes . Each material has its destination.
The water supply uses copper tubes or synthetic material.
The evacuation uses PVC :
•the polyethylene (black): cold water inlet from the counter to the stopcock,
•the polyethylene (blue band) low density : between the meter and the installation,
•the Crosslinked polyethylene (PEX) suitable for corrosive waters, used for wired hydro installations low temperature floor heating, it replaces more and more copper,
•the polyethylene on chlorinated (PVC-C): posed for power circuits in cold water, allows a complete installation and it is insensitive to scale,
•the copper : classic material used by professional plumbers,
•the gray PVC : used for disposal of waste water and sewage,
•the black steel and lead are forbidden for food and sanitary purposes. If your installation is in these materials, quickly contact a plumber to upgrade your installation .
Plumbing fittings provide the mechanical connection of the tubes and must be watertight:
•the weld connections : traditional technique ensures lasting sealed connection.
•the quick couplings : each pipe has a corresponding diameter of quick coupling. Simplify installation, but less resistant.
Fittings are available in several materials:
•copper connection : they require specific tools to make the flanged collar (used in the walls and the slab for the supply of hot or cold water),
•PVC connection : the most common with a wide range for sewage disposal (diversity of interlocking male, female, elbow fittings)
•brass fitting : used outdoors for automatic or manual watering,
•PER coupling : exclusively for PER flexible hoses (in high density cross-linked polyethylene) or PEX (international designation) for connecting the hot and cold water outlet with the tap.
In case of doubt or leak, contact several plumbers to prepare quotes as the situation is not urgent and the flood remains controllable!
Dump, bungs, siphons
The dump allows the evacuation of water through a bung and a siphon to the sewage pipes and sewers. There are classic bungs and siphons placed horizontally in the showers but also in the wall. In fact, for walk-in showers, also known as flush with the floor, evacuations and wall plugs make it possible to evacuate water in a refined way.
Be sure to maintain all three parts to avoid clogging your pipes. Our article on the maintenance of your plumbing installation will give you leads.
The faucets of your plumbing
The faucet of your installation can be of 3 types:
•the mixer : consisting of a spout and two control buttons (cold water, hot water),
•the mixing valve : a single knob adjusts the flow rate and the hot / cold water mixture,
•the thermostatic mixing valve : equipped with two knobs, one for the temperature, one for the flow of water.

The different materials for plumbing
First, the materials used to create domestic plumbing systems and the materials used for appliances connected to the plumbing system must be distinguished, as well as the materials used for water and those used for evacuation ...
For the creation of plumbing networks, we generally encounter 3 materials:
•Copper : well used, it can last for tens of years, even more than 100 years, is robust, guaranteed for sanitary use, waterproof, etc. It's the king of plumbing material, the one used for centuries!
•The PER : a flexible and cheap synthetic material used for twenty years, punctually, to replace copper on certain types of plumbing installations. Its defect is not to be in shape memory and not be waterproof to oxygen (thus risks of oxidation of the apparatus and contamination of the water), except to choose it with oxygen barrier.
•Multilayer PER : an evolution of the PER, including a metal membrane that allows to make it shape memory and to form a sealed oxygen barrier. More expensive, it is also the only material capable of competing with copper in terms of quality and stability.
For the PER : the oxygen barrier is essential for the sanitary network! For the heating network, if you absolutely want to opt for PER, then take the multilayer PER, much more robust, not expanding with heat and offering more possibilities of bending since it is memory-shape.
For the evacuation, it is exclusively towards PVC that we turn: no one makes evacuations cast iron or cement, too porous and brittle. PVC offers unbeatable advantages: robustness, low cost and ease of use and implementation.
Finally, for the apparatuses, several materials are commonly used:
•PVC for evacuations ;
•Stainless steel for evacuation
•Flexible or even PER for power supplies
What materials do plumber craftsmen use?
Plumbers and heating engineers juggle with these different materials according to the needs of the installation: often for example, for heated floors, we use multilayer PER. Similarly when it is absolutely necessary for the pipes to be concealed in a wall or under a slab: the multilayer PER pipes are then slid into ducts so that they can be easily replaced in the event of a leak or a problem.
But for the rest, especially the sanitary water network, gas networks and heating networks, most plumbers work mainly copper, other materials being anecdotal (except PVC, obviously, for evacuations).
