Plumbing isn’t all about lengths of PVC or copper! A small revolution in the field, the PER makes life easier for professionals and amateurs alike, wishing to carry out their installations in complete autonomy. What is it about? How to choose it and connect it? We will tell you everything!
What is a PER tube?
This is a high density cross linked polyethylene pipe. Under this technical name, hides in reality a semi-rigid pipe, designed specifically to create domestic water networks (hot and cold), in the fields of plumbing or heating; its big difference with copper pipes being in the fact that soldering is not necessary, replaced by mainly screwed or crimped fittings.
What is the difference between PER and multilayer?
The multilayer embeds all the advantages of PER. In addition to being able to be installed surface-mounted or recessed, it offers easier bending than other materials, better resistance to pressure, as well as to temperature variations. It is, however, more expensive than PER.
What are the advantages and disadvantages of PER pipes?
PER has different advantages, making it particularly popular in recent plumbing installations:
- It is economical;
- Its lifespan is similar to that of copper;
- It does not build up;
- It is not subject to corrosion;
- It is very easy to handle and implement ;
- It is relatively light;
- It can be installed seamlessly over very long lengths;
- It offers good sound insulation during water circulation;
Like any equipment, it also has its share of drawbacks, which are relatively small, if the advantages mentioned above are taken into account.
- The prices of its Threaded Fittings Malaysia remain relatively high;
- Left visible, PER degrades under the effect of UV. This pose is therefore not recommended;
- Its margin of curvature is reduced compared to copper;
- Its thermal expansion can quickly strain its connections;
How to choose the right PER pipe? The criteria to check
Opting for PER tubes means taking a number of criteria into account before going to the cash register. Among these:
The color: Blue for cold water, red for hot water. PER pipes are very easy to identify, but this criterion must still be taken into account, as needed;
The diameter: It must be adapted to the water flow in the installation; two numbers, corresponding to the interior and exterior measurements, then make it possible to make the right choice;
The rate of deformation, or coefficient of expansion: sometimes considered as a weak point of PER;
How to create a PER network and connect the tubes?
Do you want to build your own piping network, to connect your sanitary equipment or your household appliances? Follow the guide!
To get started, know that you can only intervene on certain parts of your installation.
At home, you cannot touch the part of the installation before the meter, and the meter itself;
In an apartment, you can only intervene from your water meter; the rest of the piping under the condominium;
To complete, and in any event, the installation of non-return valves remains compulsory, under the regulations.
