Water Filter for Home THREAD 1'' Pre-Mechanical Water Treatment Filter

Three-stage 1" in-line filter for the home

This is an integrated filtration module designed for effective filtration of cold water and lukewarm utility water. Three purification stages work in a single block, and the solid construction, universal connections, and convenient operation make everyday use easier.

The filter helps improve water quality right at the initial stage. It reduces mechanical impurities and supports better utility properties of the water, so it works well both as a standalone system and as a pre-stage for further filtration solutions, for example when a permeate filter or reverse osmosis filter is operating later in the installation.

Set contents

• Integrated triple 10" housing assembly Fi 1" female thread
• 9 pcs. 10" filter cartridges:
  • foam (sediment) cartridge 5 µm
  • activated carbon cartridge (granular)
  • carbon block cartridge
• Housing wrench – makes cartridge removal and replacement easier
• Mounting plate + 12 pcs. head screws – for stable fastening of the filter

The set is prepared to make installation, later servicing, and regular replacement of filter cartridges easier.

Main advantages

• Complete, integrated module – you only connect the 1" inlet and outlet threads
• Three filtration stages in one block – 5 µm foam, granular activated carbon, carbon block
• Immediate water improvement – removal of sand, rust, chlorine, pesticides, heavy metals, unpleasant tastes, and odors
• Brass threads + double sealing – high corrosion resistance and reduced risk of micro-leaks
• Minimal pressure drop – 1" female full-bore threads
• Fast servicing – cartridge replacement in less than 5 minutes
• Compact design – easy wall mounting
• Operating range 1–45 °C – for cold and lukewarm utility water

How the 3 filtration stages work

1. 5 µm foam cartridge (sediment)

• Action: deep filtration of mechanical impurities – it traps sand, silt, rust deposits, and larger solid particles.
• Working position: usually installed as the first stage, before the carbon cartridges, to protect the next filtration stages.
• Replacement: every 3–6 months*

2. Activated carbon cartridge (granular)

• Action: water clarification – reduction of chlorine, aromas and odors, organic deposits.
• Working position: second stage – pre-cleans the water, leaving it clean and neutral in taste.
• Replacement: every 3–6 months*

3. Carbon block cartridge

• Action: adsorption of chlorine, pesticides and most organic compounds, heavy metals; significant improvement of water taste and odor.
• Working position: third stage – the block cartridge excellently removes chemical substances before the water moves on through the system.
• Replacement: every 3–6 months*

This arrangement means that the first filter cartridge protects the following stages from mechanical impurities, while the next two are responsible for improving odor and taste and reducing selected chemical compounds typical of utility water.

Operation and everyday use

The filter operates passively, using the pressure present in the water installation, so it does not require electrical power. It is a convenient solution for home use where easy operation, quick access to cartridges, and effective pre-filtration are important.

Thanks to the standard 10" size, the user can also later use other compatible cartridges of this format if the installation configuration requires it.

Operating and installation instructions for the in-line filter

1. Preparation before installation

1.1. Checking the set contents

• 3 × filter housing with pre-connected heads (in one frame)
• 1 × mounting plate
• 1 × installation wrench
• 6 × O-rings (gaskets) in the heads, pre-installed
• 9 × filter cartridges
• 12 screws for fastening the plate to the heads

1.2. Tools and additional materials (not included)

• drill with ø6 mm bit
• ø6 mm wall plugs
• Phillips screwdriver (PH2)
• technical petroleum jelly
• installation water connections 1" male thread
• Teflon tape or Teflon thread to secure connection threads
• optionally, an adjustable wrench or open-end wrench for metal connections

1.3. Preparing the cartridges

1. Remove each cartridge from the plastic packaging.
2. Place the cartridges in a clean container with water and soak for 30 min.
3. After that time, remove carefully and allow excess water to drain off.

2. Selecting and preparing the mounting location for the water filter

1. Choose the location

   Behind the main shut-off valve for the water supply.

   In a space with easy access for servicing and cartridge replacement.

2. Leave at least 10 cm of free space below and above the filter frame.
3. Shut off the water supply valve and release the pressure by opening the nearest faucet after the filter.

3. Installing the mounting plate and housing frame

1. Place the mounting plate under the frame of the three heads, leveling it.
2. Mark the mounting holes corresponding to the holes in the plate.
3. Drill the holes and insert the wall plugs.
4. Screw the plate to the wall using the plugs.
5. Hang the housing frame on the plate by engaging the upper profile of the frame.

4. Installing the water connections

1. Select 1" male connectors matching the 1" female threads in the heads.
2. Wrap the male threads with Teflon tape (several turns).
3. Screw the male connectors into the female threads of the heads:

   Side marked with IN arrow – water supply from the installation.

   Side marked OUT – water outlet after filtration.

4. Tighten the connectors with an adjustable wrench until resistance is felt.
5. Connect the water installation pipes to the mounted connectors, sealing the joints.

5. Installing the filter cartridges

Reminder: the cartridges should already have been soaked for 30 min.

1. Unscrew each housing.
2. Check that the O-ring is in place.
3. Apply a layer of petroleum jelly to the O-ring.
4. Insert the cartridges into the housing in the following order:

   Mechanical (foam)

   Granular activated carbon cartridge

   Activated carbon block

5. Make sure each cartridge is seated vertically.
6. Tighten the housing by hand or with the wrench until slight resistance is felt.

6. Start-up and leak test

1. Slowly open the main water supply valve (1/4 turn).
2. Observe the set for 2–3 minutes. If you notice any leaks, slightly tighten the relevant housing or connection.
3. Once you have confirmed there are no leaks, open the valve fully.

7. Flushing and putting into use

1. Open the nearest faucet after the filter and flush the cartridges for 5–10 min.
2. Check the mounting stability and gaskets.
3. Write down the installation date on the housing label – this will help with planning cartridge replacement.
