Water supply is one of the central engineering systems of a house. The system includes pipelines, water treatment and other equipment. The main conditions for the reliable operation of the system and the compliance of water with sanitary standards are timely service maintenance of the water supply.
Before listing the primary work performed during maintenance, we will shortlist equipment and communications included in this system.
- pipelines and risers
- Source of water supply: This source is a well or an open-source (reservoir, etc.) in autonomous systems. In centralized systems, it is a water supply system. Various pumping equipment delivers water from the source to the house.
- Water purification and water treatment systems: In many areas, the quality of water from a well and an open-source leaves much to be desired. In this case, water purification and water treatment devices are installed in the system.
- Water treatment serves to bring water into compliance with sanitary standards. Water treatment provides water softening, removing dissolved metals, etc., so that dissolved elements do not damage household and heating appliances.
- Boiler for indirect heating of DHW (hot water supply) or electric tank water heater for domestic hot water
- Hydraulic accumulator: It is used in the autonomous water supply of country houses, accumulates water coming from the source, and gives it out in the required amount when the need arises.
- The expansion tank of the DHW system is used to compensate for the thermal expansion of water in the system.
- Pressure sensors and shut-off valves (taps)
- Electronic control system for pumping and other equipment
Above, we have given a complete list of equipment used in individual water supply systems. At the same time, any country house has its characteristics. An appendix to the service contract is drawn up to take them into account, which lists the equipment to be serviced at a particular facility.
Water supply service – scope of work
Since the equipment used in water supply systems is diverse, and the mode of operation of each house is individual, there is no single regulation for service work. Specific measures are determined by the equipment manufacturer and given in the documents.
Maintenance of water supply without fail includes inspection of all pipelines and equipment for leaks and assessment of the system’s general condition.
- Checking the tightness of all connections
- Checking the pressure switch that controls the operation of the borehole pump. Adjustment if necessary
- Checking the accumulator, check the initial air pressure in the tank
- Electrical check, cleaning the pressure switch terminals
Water purification and water treatment:
- analysis of the composition of water before and after water treatment
- checking the tightness of pipelines and connections
- inspection and performance check of regenerative tanks
- cleaning the mesh filter, washing the injector, replacing carbon filters
- UV lamp replacement
- treatment of the sorbent with a regenerating solution
Preparing for the winter period:
- Draining water from all pipelines located outside the building. Valves must be left ajar by about 50%
- ventilation vents of the caisson are covered with rags (to prevent freezing of the well)
- If the house is not heated, it is necessary to drain the water from the internal water supply system. Ideally, you should blow out the system with compressed air to remove residual moisture.
This is not a complete list of works carried out during the maintenance of the water supply. The list of results for a specific facility is determined based on the system’s features, installed equipment, the wishes of the customer and is reflected in the annex to the service contract. We recommend maintenance twice a year, in spring and autumn.
Possible signs of the need for maintenance of water systems
The reason for contacting an organization engaged in the maintenance of autonomous water supply systems may be any changes in their usual functioning. For example, a long absence of water in the tap, or vice versa, its pressure is too high, water leakage is detected, and any other signs.
Conclusions
If you notice that the water supply system is malfunctioning, the first step is to pick up the instructions for its operation. At the same time, it is strictly forbidden to shut off the water tap in the borehole well independently. After reading the operating manual for the water supply system, you can try to determine the cause of the problem, if possible, eliminate it. But, if this work is beyond the power or there is no necessary knowledge, it is better to seek the help of professionals by dialing the phone number of a specialized company.
