The declaration of conformity of the plumbing system falls within the list of indispensable declarations to ascertain the regular installation of the systems. This is a guarantee issued by the installing company, in order to ensure compliance with current safety regulations and the correct functioning of the system itself.
The plumbing certification therefore it is a mandatory document, which is issued every time a water system is built from scratch, or a change is made to it. Furthermore, it is an important protection in the event of the sale of the property, both for the buyer and the seller.
In any case, this topic will be analyzed in the next few paragraphs, in order to understand the characteristics and implementation methods of the declaration of conformity.
What is the declaration of conformity of the plumbing system
The declaration of conformity of the plumbing system it is a mandatory certification, which certifies the regular execution and correct functioning of the water system.
Just like the certifications issued for other systems, this too must be drawn up by the company that carried out the work, in order to affirm that the works carried out have been brought up to standard.
Indeed the declaration of conformity it can only be performed by the qualified professional who installed the system, in compliance with current regulations. Therefore, when entrusting the commission for the installation of a new system, it is essential to ensure that the technician has the right qualifications to be able to issue the correct documentation.
One of the main rules on certification of conformity is Ministerial Decree 37/2008, which establishes the rules that must be applied for the design, construction and maintenance of systems inside buildings, especially those used civil. The same standard also introduced the declaration of compliance which has the objective of ascertaining the regular installation of a system that has already been built and does not have a declaration of conformity.
In any case, these certifications can only be issued by qualified companies that meet all the essential requirements.
How to make the declaration of conformity of the plumbing system
The declaration of conformity of the sanitary water system it can only be carried out by an authorized company, which has the appropriate certifications for the construction of the systems indicated in the company’s Chamber of Commerce.
In particular a example of declaration of conformity of the plumbing system it can be the one created in a pre-compiled document, in which it is necessary to enter the data useful for the effectiveness of the certification.
Attached to it there are additional three documents essential for the validity of the same, these are:
- the list of materials used to build the system;
- the technical diagram of the system, drawn in the map of the building;
- the copy of the chamber of commerce trade issued by no more than 6 months.
All documentation must be written in triplicate for the following subjects:
- the company;
- the owner of the property;
- the competent office in the Municipality of reference.
The declaration of conformity of the water system of a building for civil use, must be produced whenever a new system is installed, or in the case of extraordinary maintenance or any modifications. It is a very important document not only to guarantee the safety of the system itself, but also to request certain incentives or in the case of the sale of the property.
Declaration of compliance of the plumbing system: the characteristics
The declaration of compliance of the hydraulic system it should not be confused with certification of conformity. In fact, the first was introduced with the Ministerial Decree 37/2008 and regulated by D.P.R. 447/91with the aim of going to remedy from a documentary and safety point of view, all those systems that do not have a declaration of conformity.
It therefore appears evident that the scope of application of the declaration of compliance depends on the date of construction of the plant. In particular, it must be drawn up in the following cases:
- when there is no certification of conformity for systems built between 13 March 1990 and 26 March 2008;
- when the certification of conformity has been issued but does not comply with the essential parameters required by law.
Consequently, this differs from the declaration of conformity of the plumbing systemas it certifies an already built system and not a newly installed one.
In any case, these documents are an integral part of the system created, as they certify that it was installed in a workmanlike manner and in compliance with current regulations.
