Comprehensive Protection of Water Supply Systems: How to Prevent Accidents During Installation

Most leaks, breakdowns of household appliances, and premature wear and tear of plumbing fixtures occur not because of a lack of materials, but because of a lack of proper protection for the plumbing system. Water hammer, unstable pressure, abrasive particles in the water, and the lack of an emergency shut-off valve are the main risks for modern homes.

It is much cheaper and easier to prevent emergencies during the design and configuration phase of the intake unit. To do this, it is necessary to establish a multi-level system of safety and control valves.

The Four Basic Elements of Water Supply System Protection

Each component of the protection group performs its own highly specialized task, and their combination ensures the stable operation of the entire utility network.

1. Pressure reducer RD01-RD02

The municipal water supply system is often subject to pressure surges, especially at night or during emergency switchover operations on the main lines.

• Function: It stabilizes the pressure at safe levels (usually 3–4 bar).

• Result: Protects faucets, flexible hoses, ceramic cartridges, water heaters, and washing machines from water hammer and premature wear.

2. Mechanical (coarse) filter F1–F3, F11-F16, PPF01-PPF02 

Tap water contains a large amount of fine abrasive particles: sand, scale from old pipes, and rust.

• Function: Mechanical filtration of solid impurities using a mesh element.

• Result: Prevents clogging of aerators, damage to injector seals, and abrasive wear of the internal mechanisms of the valves.

3. Check Valve KL1-KL4, KL11-KL16

It is necessary to ensure unidirectional flow of the working medium.

• Function: Prevents backflow of water in the event of a pressure drop in the riser or when pressure is equalized between the hot and cold water lines.

• Result: It prevents water from being «overflowing» through the faucets, ensures that the water meters function properly, and protects the system from running dry.

4. System Water Control Flood Prevention System AFS01

A modern engineering solution for automatic fault localization.

• Function: Sensors detect moisture on the floor and send a signal to the control module, which immediately instructs the servo motors to shut off the inlet valves.

• Result: It minimizes the effects of potential burst pipes and fully protects your property from flooding, even when you're away.

FADO's Systematic Approach to Engineering Safety

Using individual protective components provides only partial protection. Maximum reliability is achieved when all components of the inlet assembly are selected from a single brand, which ensures compatibility in terms of operating pressure, materials, and thread types.

FADO products are designed to withstand the harsh operating conditions of Ukrainian water supply systems, ensuring a high margin of safety for every component.

A properly configured water supply inlet assembly is a long-term investment in the safety of your property and the peace of mind of its users. A comprehensive approach to selecting control and safety valves makes it possible to completely eliminate the risk of most common accidents.
