The act of hydraulic testing of the heating and water supply pipelines system
Heating and water supply systems are checked:
- when entering a new engineering communications;
- when reconstructing an existing one;
- during a routine check of the system functioning.
A step-by-step check and its results are recorded in the test report. The system is tested for tightness and strength in two ways, one of which is the hydraulic method: testing by using water with increased load. This method is suitable for indoor and outdoor systems (at temperatures not lower than + 5C). The second method is pneumatic.
Both acceptance testing methods are called pipe pressure testing.
The results of the inspections are recorded in the act, the form of which is established by the Code of Rules for building codes and regulations. The template is presented in Appendix 1 to SANPin "External networks and structures of water supply and sewerage". The presented form of the act is mandatory.
The procedure for drawing up an act:
1. Indication of corporate information: city of compilation and date.
2. Representation of the members of the commission, which carried out pressure testing and acceptance of the pressure pipeline. Three parties become members:
| The company that installed the pipeline |
| Technical supervision representative from the customer |
| Operating company representative |
3. Below is information about the tested object and a description of the pipeline (length, diameter, material of pipes and joints), the information specified in the working documentation, provides information about the pressure gauge used.
4. The section on the test and its results is completed.
5. In the "Commission Decision" section, a statement is made that the system is considered strong and sealed and is signed by the members of the commission.

Pneumatic pipeline test certificate
Pneumatic method: diagnostics by inflating the system with high pressure air. The method is often used for outdoor systems if the temperature on the thermometer is less than +5 Celsius.
The procedure for crimping pipes by pneumatic testing is given in the same SanPin, the test report is drawn up in a mandatory form, which is given in Appendix No. 3.
Requirements for the preparation of test documentation:
- Filling in the name of the city and the date of compilation.
- The indication of the members of the commission (as well as in the hydraulic test, three parties are involved).
- Description of the pipeline: length, diameter, material of pipes and joints.
- Information about the pressure value: calculated, to what value the pressure in the pipes was increased, the final pressure, the amount of decrease. The crimping time is indicated.
- In the section "Decision of the Commission", each of its members puts a signature with a decoding, if the pipeline has passed pneumatic diagnostics, and is hermetically sealed and durable.
Hydropneumatic flushing
As mentioned earlier, hydropneumatic flushing of the pipeline heating system is carried out using a special slurry. This method of descaling pipes involves the use of a large amount of water. Houses connected to central heating or water supply use hot water circulating in pipes. If the heating system is in a private house, then purification is carried out using cold water supply.
Hydropneumatic cleaning
When flushing the heating with hydropneumatic pressure cleaning, the following sequence of actions is performed:
- water is forced to circulate in the opposite direction to heating, then it is started again;
- compressed air is blown in together with the incoming liquid using a compressor;
The resulting stream copes well with sludge, but does not sufficiently wash out salt deposits and rust formed on the walls of the pipeline and radiators. When risers are used in heating, during the process they are blocked in groups and rinsed. The fewer risers are included in the group, the better the radiators will be cleaned.
When self-cleaning the heating, it is very important to carry it out until the waste liquid is as clean as possible and no longer contains rust particles and sediment.
Test report of external and internal sewerage system for the strait
The test report for internal and external sewerage is drawn up as a result of checking the system's performance. It fixes the position of the commission that the system has passed the water spill test, and the design complies with the design documentation, GOSTs and standards.
Diagnostics of the normal functionality of the sewer system is necessary when installing a new facility or after carrying out repairs to an existing system. The health check information is entered into the act. The form is drawn up in the form specified in Appendix "D" to the Code of Rules 73.13330.2012.
The act specifies:
- the name of the system and the object in which it is installed;
- information about the members of the commission. We need representatives of three organizations: the general contractor, the customer and the installation company;
- information about the name of the project is registered;
- the results are entered: the number of simultaneously connected devices, as well as the connection time or water filling per floor (the unnecessary is crossed out);
- in the third paragraph, it is prescribed that no leaks were found at the joints and through the walls. This means the system is usable.
Members of the commission sign for the decision.
Fire test certificates
In the course of testing for the operability and safe operation of fire fighting equipment, several acts are drawn up:
- checking fire hydrants;
- internal water supply diagnostics;
- check for safety of use and compliance with the rules of labor protection of fire escapes.
Fire hydrants
Checking the performance of hydrants for water loss is carried out twice a year and, often, is combined with checking the fire-fighting water supply system. Based on the results of the inspection, an act is drawn up, which is signed by the commission. Mandatory members: a representative of the fire inspection and a representative from the organization in which the inspection is taking place. Also, the commission may be entirely composed of company employees.
The act indicates:
- corporate information (information about the company, date and place of compilation);
- the main part describes the members of the commission and the course of the test. Information about hydrants is presented in a tabular form. Indicate the location address, diameter, head, water yield and hydrant ownership;
- in the final part, compliance (or non-compliance) with the requirements of the state of the hydrant is established.
At the end, the act is signed by the authorized members of the commission.
Internal fire-fighting water supply
The act establishes the presence or absence of defects and malfunctions in the fire-fighting water supply system. The check is carried out by the responsible employees of the enterprise. Frequency - at least twice a year, for flammable industries, inspections may be scheduled more often.
Internal fire-fighting water supply (ERW) is a complex system of pipes, sensors, switches. Therefore, it is often checked by an occupational health or fire safety specialist, as well as by persons who are trained in fire safety.
The act is drawn up on letterhead or plain paper, indicating the details. Be sure to register:
- information about the organization and participants of the audit;
- information about the checked object;
- results of inspections;
- recommendations for elimination of defects and malfunctions, if any;
- signatures of responsible persons.
If additional documents are attached to the act, their list and name are indicated.
Fire ladders
Testing of firefighting equipment, including ladders and ladders, is regulated by a special GOST. The inspection can be carried out by organizations that have received permission from the Ministry of Emergencies and have special equipment for this.
The test results are recorded in the test report. The documentation contains standard information about the organization and its details, information about the members of the commission. The main part contains information about the inspected objects (the number of stairs and stepladders, their inventory numbers and belonging to the structural unit), information on the results of inspections (absence or presence of defects). A prescription is given to eliminate the identified malfunctions.
At the end, the act is signed by the members of the commission.
Crimping act
Pressure testing can only be carried out by authorized licensed organizations that service the heating systems of a residential building. In apartment buildings, these activities are carried out by a service office. Upon completion of the tests, a corresponding document is issued. The form of the certificate for pressure testing of the heating system is given below.
The document must contain the following mandatory clauses:
- The name of the system or section, as well as its length.
- Control and testing devices and tools with which the tests were carried out.
- The duration of the pressure test and the generated pressure.
- The values on the devices that were obtained during the events.
- The act is signed by the customer, the foreman who carried out the pressure testing, the acceptance of the works. The certificate of the specialist who is responsible for conducting the tests must be indicated.
The responsible person for carrying out work in an apartment building is the communal service. When hydrotesting in a private house, the owner of the house is considered the responsible person.
Crimping price
The total cost of the work is calculated in the final estimate, which indicates all the activities and tests carried out. It is impossible to indicate the exact amount, since much depends on the type of wiring, the state of the system and other parameters.
When calculating the total cost of work, the following is taken into account:
- The amount of work carried out, which depends on the size of the house, the branching of the network.
- The state of the heating system. It is cheaper to test on a new system or networks that have been serviced recently. If you have to deal with old networks that have not undergone preventive maintenance for a long time, then the price will be higher.
- The number of defects and damages, as well as the complexity of repair and restoration work, are taken into account.
If, after hydrotesting, leaks and parts were identified that need repair or replacement, then the repair operations are carried out by a qualified specialist. The cost of these works is also included in the overall estimate.After repair and restoration measures, repeated pressure testing is carried out. All the work done is included in the total cost of testing activities.
Roof fencing test report
Technical requirements and test methods for roofing are fixed in the same GOST as the standard for fire escapes and stepladders (53254-2009).
Tests are carried out at intervals of five years, integrity checks are carried out every year. The results are formalized by acts.
The conditionally completed act can be divided into three parts:
- General information. This is where information about the test object and the testing organization is entered.
- Information about the check (what manipulations were carried out, what tools were used).
- Inspection results (compliance with GOST, structural integrity and safety).
The agreement of the members of the commission during the test is confirmed by their personal signatures.
Organizations licensed from the Ministry of Emergency Situations have the right to conduct inspections and tests. Defects found must be eliminated.
Test report for ladders, racks and stepladders
Inspection and testing of racks, ladders and stepladders is carried out at least once every six or twelve months (depending on the test object and the material from which it is made).
Tests and inspections for safe operation can be carried out by specialized organizations from the outside or by a commission specially created at the enterprise. At the same time, its members must be trained, the chairman of the commission is usually an occupational safety or fire safety engineer.
As a result of the diagnosis, the commission draws up an act, it is better to issue it with the date of the inspection. The title of the document, date and place of compilation are indicated in the header. It is also important to indicate the details of the organization, list the members of the commission: their positions and full names.
In the main part, describe the tests of ladders, ladders and racks:
- how many were checked, their inventory numbers, belonging to the workshop and department;
- what load and for how long it was used;
- presence and absence of defects;
- the presence of the affixed inventory number.
As a result of the check, the suitability (or unsuitability) for use is established: they are safe, withstand the intended load, have no defects in connections and fasteners, have no sharp edges and burrs.
The signing of the act by the members of the commission indicates agreement with the results of the audit.

Preparing for the heating season
Hydraulic testing of heat supply lines is an important factor for their smooth operation. Over time, all elements of these engineering structures wear out and can fail at the most inopportune moment. To prevent this from happening, two important measures need to be taken before the start of the heating season.
More details on how to perform hydraulic tests of heating systems:
Hydraulic tests
Each building heating system has a specific operating pressure. It is this parameter that determines the level of heating of the premises, the quality of fluid circulation, as well as heat losses. The choice of the line operating pressure indicator is influenced by various factors - the type of structure, its number of storeys, the quality of the pipeline, etc.
The heating system test is needed to measure the pressure and determine the heating level
During the movement of the coolant through the pipes, a large number of different hydraulic processes occur. As a result, pressure drops are observed throughout the system, called water hammers. Due to these loads, the service life of all elements of the heating system is reduced.Thus, the tests must be carried out at a pressure of 1.2-1.4 times the nominal value.
To carry out a pressure test, you must first fill the system with water. Then you need to raise the pressure to the calculated one, controlling the process with a pressure gauge. After completing these steps, the system should remain pressurized for 30 minutes. If during this period of time it did not fall, no leak was observed in the elements of the system, then the test is considered passed.
It should be noted that in some situations a pressure drop of up to 0.1 atmosphere is allowed. At the same time, a visual inspection should not reveal leaks, as well as violations of the tightness of threaded and welded joints. If the system fails the test, repairs are required. After their completion, pressure testing is performed again.
Testing the heating system will help identify leaks
