Description
DIAMOND3/4 Self-Cleaning Inline Mechanical Water Filter Pre-Filter SET is a practical water filter for preliminary protection of installations against sand, rust, and installation residue. Thanks to the backwash function, drain valve, and built-in pressure gauge, it supports convenient water treatment at the first stage of protecting the installation and devices working with a home water filtration system, including solutions such as a osmosis filter, reverse osmosis filter, or reverse osmosis system.

Effective protection of the water installation at the pre-filtration stage
The self-cleaning DIAMOND 3/4" mechanical filter has been designed as a modern solution for protecting water installations against mechanical impurities. Its purpose is to capture deposits such as sand, rust, and installation residue that may appear in the water and affect the durability of fittings, devices, and the entire installation.
This is an inline pre-filter that helps maintain better operating conditions for a domestic or utility water installation. Limiting the inflow of mechanical impurities is an important element in protecting valves, taps, connections, and subsequent filtration stages.
Main features and functions
Backwash without disassembly
The effective backwash function makes it possible to remove accumulated contaminants without the need to disassemble the filter. This solution significantly simplifies routine maintenance and allows you to restore its high efficiency more quickly.
Drain valve for convenient cleaning
The applied drain valve simplifies the maintenance process and allows easy removal of contaminants accumulating at the bottom of the housing. As a result, filter operation is more convenient, and cleaning can be carried out efficiently and without unnecessary complications.
Built-in pressure gauge
The pressure gauge allows monitoring the pressure in the installation, which is important for maintaining the correct operating parameters of the filter. Ongoing pressure control helps better assess the system's operating conditions and supports proper operation of the water installation.

Why choose the DIAMOND 3/4 filter
This model combines effective mechanical protection with everyday convenience. It works well where installation durability, simpler maintenance, and quick access to basic operating parameter control matter.
Installation protection – effectively protects installations against mechanical impurities, helping to extend their service life.
Self-cleaning design – the backwash function supports long filter life and maintaining high efficiency.
Easy operation – the drain valve and pressure gauge make daily use and maintenance easier.
Versatile use – the filter is suitable for various types of installations, providing reliable protection against contaminants.
Application
The filter is suitable for houses, apartments, and other properties equipped with water installations where effective protection against mechanical contaminants is needed. It can operate as a pre-filter, helping protect installation components and further water treatment and filtration devices.
This is a particularly practical solution wherever contaminants such as sand, rust, or installation sediment can negatively affect the operation of fittings and installation components.
A pre-filter works best as part of a regularly monitored filtration system. Periodic backwashing and removing sediment through the drain valve helps maintain high performance and convenient operation.
User comfort and operation
Daily operation of the filter has been simplified thanks to solutions that support quick cleaning and device control. Backwashing allows the accumulated sediment to be removed without taking the filter apart, and the drain valve makes it easy to discharge contaminants from the housing.
An additional advantage is the pressure gauge, which makes it easier to monitor the pressure in the installation on an ongoing basis. Such control supports maintaining proper operating conditions and allows quicker response to changes in the installation.
