Installing a Harvey HV3 water softener (a non-electric, twin-tank model) involves a sequence of plumbing connections and system priming. Because this unit operates on water pressure rather than electricity, correct pressure and flow direction are critical for performance. 1. Pre-Installation Requirements
Location: Choose a level, dry indoor spot near the main water entry point and a drain.
Water Pressure: Must be between 1.7 bar and 6 bar. If pressure exceeds 6 bar, install a pressure limiting valve to prevent damage.
Tools/Parts: Ensure you have a standard bypass valve set and WRAS-approved flexible hoses. 2. Plumbing Installation
Isolate Water: Turn off the internal main stopcock and drain the lines by opening a nearby tap.
Install Bypass: Fit a three-valve bypass manifold (Inlet, Outlet, and Bypass valves) into the main water line. Connect Hoses: Remove red plastic caps from the unit's ports.
Connect the Inlet (hard water in) and Outlet (soft water out) using flexible hoses, following the directional arrows on the unit. Connect Drain and Overflow:
Drain Hose: Attach the 3/8” drain tube to the center outlet. Run it to a waste pipe using an air gap fitting to prevent siphoning.
Overflow Hose: Connect a separate hose to the white spigot on the side of the cabinet. This must run downhill through an outside wall to a visible point. 3. Commissioning & First Use
Flush the System: With the softener's outlet valve closed and the bypass open, slowly open the inlet. Open a soft water tap (like the kitchen tap) to flush air and debris.
Manual Regeneration: Insert a flat-blade screwdriver into the white button under the cover. Press and rotate one full turn clockwise until it pops back up. The unit will drain for roughly 10–12 minutes.
Add Salt & Water: Manually add approximately 5 liters of water to the cabinet (covering the salt platform by about 10mm) and then add your block salt.
Check for Leaks: Monitor all joints while the unit is under pressure. 4. Maintenance BLOCK SALT SOFTENER INSTALLATION INSTRUCTIONS
Installing a Harvey HV3 Water Softener (a model often associated with the Minimax M3
or similar block salt systems) generally involves positioning the unit near your main water inlet and setting up a bypass valve for maintenance.

Harvey HV3 Water Softener Installation Manual: A Step-by-Step Guide
The Harvey HV3 is one of the most compact and efficient twin-tank water softeners on the market. Known for its non-electric design and continuous softened water supply, it’s a favorite for UK households. While we always recommend professional installation by a Harvey-trained engineer, this guide provides a comprehensive overview of the installation process for those looking to understand the manual requirements. 1. Pre-Installation Checklist
Before you begin, ensure you have the correct tools and have checked your plumbing compatibility. Tools Needed: Pipe cutter or hacksaw Adjustable spanners Drill (if wall-mounting or creating a waste exit) Site Requirements:
Space: The HV3 is designed to fit under a standard kitchen sink. Ensure the surface is level and capable of supporting the unit's weight when full of salt and water.
Water Pressure: The HV3 operates best between 1 and 10 bar. If your pressure exceeds 6 bar, installing a pressure-reducing valve is highly recommended.
Plumbing: You will need access to the rising main, a waste pipe, and an overflow point. 2. Positioning the Unit
Place the HV3 as close to the incoming water main as possible, but after the outside tap branch (unless you want softened water for your garden).
Orientation: Ensure there is enough room in front of the unit to load block salt.
Accessibility: Leave enough slack in the hoses so the unit can be pulled out for maintenance. 3. The Bypass Valve Installation
A bypass set allows you to isolate the water softener if you need to perform maintenance or if you are moving house.
Turn off the mains water supply and drain the pipes by opening the lowest kitchen tap. Cut the pipe: Install the inlet and outlet tees.
Install three valves: One for the inlet (to the softener), one for the outlet (from the softener), and a "bypass" valve in between.
Check Flow Direction: Ensure the arrows on the valves match the direction of the water flow. 4. Connecting the Hoses
The Harvey HV3 uses flexible, high-quality hoses to connect the unit to your plumbing.
Inlet: Connect the incoming hard water to the "In" port on the back of the softener.
Outlet: Connect the "Out" port to the pipe leading to your household taps.
Seal: Use the provided washers and ensure connections are firm, but do not over-tighten as this can damage the plastic threads. 5. Waste and Overflow Connections
Because the HV3 is non-electric, it uses water pressure to regenerate. This requires two drainage lines. The Drain Line (High Pressure) Connect the 1/2" drain hose to the softener's drain outlet.
Run this to a standpipe or a waste trap (e.g., under the sink).
Crucial: Maintain an air gap of at least 20mm between the end of the hose and the water level in the trap to prevent back-siphonage. The Overflow Line (Gravity Fed) Connect the overflow hose to the side of the cabinet. Installing a Harvey HV3 water softener (a non-electric,
This pipe must run downhill to an outside wall. It is a safety feature in case the unit malfunctions; it ensures excess water exits the building rather than flooding your kitchen. 6. Commissioning the HV3
Once everything is connected, it’s time to start the system.
Slowly open the inlet valve: Let the tanks fill with water gradually. Open the outlet valve: Close the bypass valve. Check for leaks: Inspect every joint and hose connection.
Run a tap: Open a cold-water tap for a few minutes to clear any air pockets and fine resin particles.
Add Salt: Insert two blocks of Harvey salt into the front compartments. 7. Testing for Softness
After installation, use a water hardness test kit on your kitchen tap. The reading should be 0ppm. Note that your hot water cylinder may take several days to transition from hard to soft water as the existing scale begins to dissolve. Troubleshooting Tips
Low Water Pressure: If you notice a drop in pressure, check that the bypass valves are fully open.
Constant Water to Drain: This usually indicates a piece of debris is stuck in the internal valve. Turn the unit to bypass and contact a technician.
Salt Not Dropping: Ensure the salt blocks are not "bridging" (stuck together). Always use high-quality Harvey Block Salt.
Disclaimer: This guide is a summary of the installation process. Always refer to the physical manual provided with your Harvey HV3 for specific technical drawings and warranty-specific instructions.
✅ Pro tip: Always install a bypass loop. If you don’t have a built-in bypass valve, add two full-bore lever valves and a crossover pipe so you can isolate the softener for maintenance.
Because the Harvey HV3 is non-electric, calibration is mechanical. This is the most misunderstood part of the manual.
The manual is clear: the HV3 is low-maintenance, but not no-maintenance.
The Harvey HV3 water softener installation manual is not just a set of instructions – it is the blueprint for decades of trouble-free soft water. By reading it carefully, following the step-by-step plumbing guide, respecting the water pressure limits, and adhering to the maintenance schedule, you will avoid 95% of common softener failures.
Whether you are a DIY enthusiast or a professional installer, treat the manual as your primary reference. And remember: a correctly installed Harvey HV3 should last 20 years or more. A rushed, incorrect installation will fail in 20 months.
Now turn off your water supply, gather your tools, and open that manual one more time. Your soft water journey starts here.
