Product Information
Full details
The Hanicks Sesi Electrolytic Scale Inhibitor is for homeowners seeking an economical and eco-friendly solution to combat limescale buildup and corrosion in their water systems. Its key benefit is protecting household water systems and appliances without requiring power or chemicals. A potential caveat is that its effectiveness can vary based on water hardness and flow rates. This compact, all-metal device installs inline to alter water chemistry, preventing scale from adhering to heating surfaces and pipes. It features WRAS approval and is available in compression and push-fit models.

FAQs
How does the Hanicks Lime Fighter work?
It uses an electrolytic process where it releases minute quantities of metal ions, typically zinc or iron, into the water. These ions alter the water's chemical properties, preventing calcium carbonate (limescale) from forming hard deposits and instead causing it to precipitate as a fine powder that passes through the system.
Do I need any special tools to install it?
For the compression model, you will typically need a pipe cutter, adjustable wrenches, and possibly a pipe de-burring tool. If you opt for a push-fit model, fewer tools are generally required, often just a pipe cutter and ensuring the pipe ends are clean and square.
Is it safe for drinking water?
Yes, the Hanicks Sesi Lime Fighter is WRAS approved (WRAS Approval Number: 1905028), meaning it has met stringent standards for safety and suitability for use in contact with drinking water in the UK.
How long does the unit last?
The all-metal construction is designed for durability. While the electrolytic action gradually depletes the sacrificial metal anode, these units are generally long-lasting, often providing many years of service without maintenance.
Can I install this on any pipe material?
The 15mm compression fittings are typically used with copper or plastic (like PEX or PB) pipes. Ensure your pipe material is compatible with compression fittings and suitable for water systems.
Will this remove existing limescale?
The primary function is to prevent *new* limescale from forming and adhering. While conditioning the water may help to loosen some existing scale over time, it is not primarily designed as a descaler for heavy, pre-existing deposits.
What is the flow rate capacity?
This 15mm unit is rated for a flow rate of up to 0.6 Litres per second (L/s).
Troubleshooting
No reduction in limescale observed after installation.
Allow sufficient time (several weeks to months) for the inhibitor to condition the water and show noticeable effects. Check that the unit is installed in the correct flow direction and that there are no leaks around the connections. Consider testing your water hardness, as very extreme hardness levels may require additional solutions or a different type of scale inhibitor.
Leakage from the compression fittings.
Ensure the pipe ends are clean and de-burred before installation. Re-tighten the compression nuts firmly but do not overtighten. If the leak persists, the olive or sealing washer may need to be replaced.
Reduced water flow after installation.
Verify that the unit was installed correctly and is not obstructed internally. Ensure the correct 15mm fittings were used and properly tightened. This unit should not impede flow if installed correctly; check for other potential blockages in the system.
Pros and Cons
Pros
- Economical and eco-friendly solution for limescale.
- No electricity or chemical additives required.
- Low maintenance and zero running costs.
- Durable all-metal construction with a high-quality finish.
- Compact size for easy installation.
- WRAS approved for safe use with drinking water.
Cons
- Effectiveness can depend on water hardness and specific system conditions.
- Requires initial installation, which may necessitate plumbing knowledge.
- May not be suitable for very high flow rate systems.
- Alters water chemistry slightly, though generally considered safe and beneficial.
- Primarily addresses scale formation rather than removing existing heavy scale deposits.
Setup, Compatibility & Care
Setup:
- Isolate Water Supply: Turn off the main water supply to the property.
- Drain Pipe: Open a nearby tap to drain water from the pipe where the unit will be installed.
- Install Unit: Using the 15mm compression fittings, connect the Hanicks Sesi Lime Fighter inline with your pipework. Ensure the water flow direction matches the arrow on the unit. If installing on vertical pipework, ensure it is correctly oriented.
- Tighten Fittings: Securely tighten the compression nuts, ensuring a watertight seal.
- Restore Water Supply: Turn the main water supply back on slowly.
- Check for Leaks: Inspect all connections for any drips or leaks. Tighten fittings further if necessary.
Compatibility:
- Pipe Size: Compatible with 15mm pipework.
- Connection Type: Available in compression and push-fit models.
- Water Type: Suitable for both hot and cold water systems.
- Installation Position: Can be installed on horizontal or vertical pipework.
- Flow Rate: Designed for flow rates up to 0.6 L/s.
Care:
- Maintenance-Free: This device requires no regular maintenance, no replacement parts, and no chemicals.
- Cleaning: The exterior can be wiped clean with a damp cloth if necessary. Do not use abrasive cleaners. The internal electrolytic action does not require cleaning.
