With the constant evolution of techniques in the field of building, plumbing does not escape the trend of simplification and modernisation. Among these innovations, solderless plumbing is gaining popularity. But does this method really deserve the attention it is given? How to assess whether solderless plumbing is worth it?
What is solderless plumbing?
Solderless plumbing refers to all piping connection techniques that do not require the use of hot or cold welding. It is mainly based on mechanical systems such as compression, timing, interlocking or screw connections. This process is often used with modern materials such as PER (cross-linked polyethylene), multilayer or PVC, which are increasingly replacing traditional copper.
The advantages of solderless plumbing
Seamless plumbing has many advantages like any other technique.
1. Simple and quick installation
One of the great attractions of this method is its ease of implementation. Unlike conventional installations that require welding skills, seamless plumbing can be carried out without specialised training. An experienced handyman can carry out certain repairs or installations himself, which is a considerable time saving.
2. Less risk of fire or burn
The removal of the blowtorch or any heating tool significantly reduces the risks associated with heat: burns, accidental fires, deterioration of heat-sensitive materials. This makes the intervention more secure, especially in closed environments or near flammable materials.
3. Suitable for renovations
In old or difficult to access buildings, seamless plumbing is particularly practical. Mechanical fittings can be installed in small spaces, often without requiring heavy work.

4. Savings on materials and labour
The cost of the tools needed for seamless plumbing is often lower than that of welding equipment. In addition, the use of a professional can sometimes be avoided, which reduces labour costs.
The disadvantages of solderless plumbing
Like everything else, seamless plumbing also has some drawbacks.
1. Variable long-term reliability
Although modern mechanical fittings are designed to last, some types may be less durable than traditional welds. They can be especially if the installation is poorly done. Improper handling or a poorly tightened connection can lead to leaks after a few years.
2. Sometimes higher cost of connecters
Although the tools are more accessible, connections specific to seamless systems (including criming fittings) can be more expensive than standard copper materials and their traditional accessories.
3. Less aesthetic in some cases
Solderless piping, especially PER or multilayer piping, is sometimes considered less elegant than copper installations. In visible environments (such as an open kitchen or a design bathroom), this can be a criterion to consider.
4. Need for specialised tools for certain systems
Some fittings, especially crimping fittings, require specific tools (electric or manual crimping pliers), which, although easy to use, must still be available and adapted to the formats used.

An adapted solution, but not universal
Seamless plumbing represents an undeniable advance in the field of domestic and professional installation. It offers a fast, safer and often more accessible alternative to traditional techniques, especially for renovations or occasional interventions.
However, it is not without limits. For durable, complex or high stressed installations (pressure, temperature, aesthetics), welded systems retain their relevance.
Ultimately, seamless plumbing is worth it in many cases, especially for simple projects, quick renovations or tight budgets. The choice will depend above all on the specific needs of the site, the desired sustainability and the available skills.
