Understanding Hard Water and Its Effects
Hard water contains high levels of dissolved minerals, primarily calcium and magnesium. While not a health risk, these minerals cause numerous inconveniences. Common effects include scale buildup in pipes, water heaters, and appliances, reducing their efficiency and lifespan. This scaling also leads to diminished water flow and increased energy consumption.
Furthermore, hard water interferes with soap’s ability to lather effectively, requiring more detergent for cleaning. This results in dull laundry, spotty dishes, and dry skin and hair. A Tapworks water softener removes these hardness minerals through a process called ion exchange, replacing them with sodium or potassium ions. By mitigating these effects, a water softener protects your plumbing, enhances cleaning performance, and improves overall water quality, contributing to cost savings and a more comfortable home environment.

Installation Process
Professional installation is recommended, though experienced DIYers can undertake it. This section details planning, siting, and connecting the hardwater tap, valves, and pipework for optimal performance.
Planning and Siting the Installation
Careful planning is crucial for a successful installation. Select a location close to the main water supply and an electrical outlet. Ensure sufficient space around the unit for maintenance and salt refilling. The area should be level and protected from freezing temperatures.

Consider proximity to a drain for the regeneration discharge. Installation of a separate hard water drinking tap is currently recommended by the UK Department. Before starting, verify adequate water pressure. If pressure exceeds recommended levels, a pressure-reducing valve (Part No. 800220 for 1/2 or 15mm pipework, Part No. 800223 for 3/4 or 22mm pipework) will be necessary.
A bypass valve is also essential, allowing continued water supply during servicing. Remember, the system requires a maximum flow of 3.18m. Ensure easy access for future servicing and salt additions.
Hardwater Tap Installation
Installing a dedicated hard water tap is highly recommended, particularly in the UK, to maintain a supply of untreated water for drinking and other specific uses. This tap should be fitted before the water softener in the system, directly from the mains water supply.
Ensure the tap is installed in an accessible location, typically in the kitchen. Use appropriate plumbing fittings and sealant to prevent leaks. The tap should be clearly labelled as “Hard Water – Do Not Soften”.

This separate tap provides unsoftened water, preserving essential minerals and offering a choice between softened and unsoftened water. Fitting a separate hard water drinking water tap is a current recommendation, ensuring access to water unaffected by the softening process. Proper installation guarantees a reliable and safe source of hard water when needed.
Pressure Reducing Valve (If Required)
If your mains water pressure exceeds recommended levels, a pressure reducing valve (PRV) is essential to protect your Tapworks water softener and prevent damage. High pressure can strain the system’s components and shorten its lifespan.
Tapworks offers a suitable PRV, Quote Part No. 800220 for 1/2 or 15mm pipework, which can be ordered directly from them. The PRV should be installed before the water softener in the main water line.
Proper installation involves ensuring the PRV is correctly oriented (follow the manufacturer’s instructions) and securely connected to the pipework. After installation, verify the reduced pressure using a pressure gauge. Maintaining appropriate water pressure is crucial for optimal softener performance and longevity, safeguarding against potential issues caused by excessive force within the system.
Bypass Valve Installation

A bypass valve is a critical component, allowing you to isolate the water softener for maintenance or repairs without interrupting the water supply to your home. It also provides a source of untreated water if needed.
Tapworks recommends installing a bypass valve (Part No. 800223 for 3/4 or 22mm pipework). This valve should be installed before the inlet valve of the water softener and after the outlet valve. Ensure the bypass valve is positioned to allow for easy access and operation.
During installation, verify proper flow direction and secure all connections to prevent leaks. Regularly test the bypass valve to confirm it functions correctly. A functioning bypass valve is essential for convenient maintenance and ensures a continuous water supply, even when the softener requires servicing or replacement.
Inlet Valve Connection (1/2 or 15mm)
Connecting the inlet valve correctly is crucial for proper water softener operation. For 1/2 or 15mm pipework, utilize Tapworks Part No. 800220. Ensure the water supply is shut off before beginning this step.
Carefully align the inlet valve with the incoming water pipe. Apply appropriate thread sealant (PTFE tape is recommended) to the male threads to prevent leaks. Tighten the connection securely, but avoid over-tightening, which could damage the valve or pipework.
Double-check the connection for any signs of leakage after restoring the water supply. A secure and leak-free inlet valve connection guarantees a consistent water flow to the softener, enabling efficient water softening and protecting your plumbing system. Proper installation is vital for optimal performance.
Outlet Valve Connection (3/4 or 22mm)
Establishing a secure outlet valve connection is essential for delivering softened water throughout your home. For 3/4 or 22mm pipework, use Tapworks Part No. 800223. As with the inlet, shut off the water supply before commencing work.
Align the outlet valve with the existing water pipe leading to your home’s plumbing. Apply a suitable thread sealant, such as PTFE tape, to the male threads to ensure a watertight seal. Carefully tighten the connection, avoiding excessive force that could compromise the valve or pipe integrity.
Once the water supply is restored, meticulously inspect the connection for any leaks. A properly installed outlet valve guarantees the delivery of consistently softened water, protecting your appliances and enhancing your water quality. Regular checks are recommended.

Troubleshooting Common Issues
This section details solutions for low water pressure, regeneration problems, salt bridge formation, and deciphering error codes displayed on the control panel for optimal performance.

Low Water Pressure Problems
Reduced water pressure after softener installation often stems from several easily addressable causes. First, verify the bypass valve is fully open; a partially closed valve restricts flow. Next, inspect the inlet and outlet valves for obstructions or incomplete opening. Ensure the pressure reducing valve (if installed) is functioning correctly and set to the appropriate pressure – too low a setting will diminish pressure throughout your home.
A build-up of sediment within the softener’s resin tank or within the plumbing lines themselves can also contribute to pressure loss. Consider a professional plumbing inspection to flush the system and clear any blockages. Finally, confirm that your home’s main water pressure is sufficient; the softener requires adequate incoming pressure to operate efficiently. If issues persist, consult a qualified plumber for further diagnosis and repair.
Regeneration Cycle Issues
Problems during the regeneration cycle can indicate several underlying issues. If the cycle fails to initiate, check the control panel for error codes and ensure the system is properly programmed with the correct time and hardness settings. Insufficient salt levels are a common cause of incomplete regeneration; always maintain an adequate salt supply in the brine tank.
A salt bridge – a hardened crust forming on top of the salt – can prevent the softener from drawing brine. Break up the bridge manually. Also, verify the brine line isn’t kinked or blocked. If the regeneration cycle runs continuously, it may signal a problem with the control valve or flow meter. Consult the error code section of this manual or contact Tapworks support for assistance. Regular maintenance, including periodic cleaning of the brine tank, helps prevent these issues.

Salt Bridge Formation
Salt bridge formation is a common issue in water softeners, occurring when undissolved salt hardens into a crust on the surface of the salt bed within the brine tank. This crust prevents the softener from accessing the salt needed for regeneration, leading to hard water breakthrough. High humidity and infrequent softener use contribute to this problem.
To resolve a salt bridge, carefully break it up using a broom handle or similar tool, avoiding damage to the tank. Ensure you are using the correct type of salt – only tablet or pellet salt is recommended. Regularly inspect the brine tank, ideally monthly, and break up any minor crusting before it becomes a significant bridge. Maintaining a consistent water level in the tank and avoiding overfilling can also help prevent salt bridge formation, ensuring optimal softener performance.
Error Codes and Their Meanings
Your Tapworks water softener utilizes error codes to diagnose potential issues. While specific codes may vary depending on the model (like the AD11), understanding these alerts is crucial for efficient troubleshooting.
