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). harvey hv3 water softener installation manual
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.
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.

is a highly efficient, non-electric twin-tank system designed to provide continuous softened water. Proper installation is critical to protecting your plumbing system, maximizing appliance lifespan, and ensuring high-quality water flow. 📋 Pre-Installation Checklist & Site Survey
Before beginning the installation, you must confirm the following site conditions:
Water Pressure Check: The recommended operating pressure for non-electric block salt softeners ranges between If your pressure exceeds ), you must install a pressure limiting valve. Low pressure can prevent proper regeneration cycles.
Main Water Entry Point: Identify the rising main stopcock. The softener should ideally be installed as close to this point as possible.
Physical Space and Level Ground: Softeners must always be installed on firm, flat, and level ground with adequate access for adding block salt and performing future maintenance.
Local Water Bylaws: All plumbing works must adhere to local water supply regulations and WRAS guidelines.
Access to Drainage and Overflow: You will need a suitable upstand or an outside drain nearby, featuring a proper air gap to prevent back-syphonage. 🛠 Step-by-Step Installation Process
Follow these sequential steps to safely plumb your Harvey system: 1. Isolate the Water Supply Shut off the main water supply at the rising stopcock.
Open the lowest taps in your property to drain any remaining water from the pipes. 2. Install the Bypass Valve Set A standard
fitting kit with an integrated non-return valve is required. Cut the main pipe after the stopcock.
Plumb the bypass set consisting of three separate valves: the inlet valve, outlet valve, and bypass valve. The drain line carries away the brine and
Position the valves so that the softener inlet and outlet are closed, and the bypass valve is open. This allows the main water to resume flowing into the house while you work. 3. Route Hard Water Taps (Optional)
If your local bylaws require a separate hard water line for kitchen drinking water, or if you prefer an untreated line for the garden hose, split the line before it enters the water softener's inlet. 4. Connect the Flexible Hoses
Locate the directional arrows embossed on the back or side of the softener casing indicating "Inlet" and "Outlet".
Use standard flexible braided steel or heavy plastic hoses with the included washers.
Connect the straight end of the hoses to your plumbing bypass valves and the angled ends to the softener unit. Ensure there are no sharp kinks or tight bends. 5. Hook Up the Drain and Overflow
Drain Line: Push the flexible plastic drain hose into the quick-fit center drain connection. Route this line to your upstand or outside drain. ⚠️ Critical: Ensure a minimum
air gap at the drain line's end to avoid cross-contamination. Never shove the line directly into soil or standing water.
Overflow Line: Cut a piece of hose for the overflow connection (usually located at the rear or side of the cabinet). This must be run downhill without any kinks through an outside wall. 6. Smart Setup (The myHarvey App)
Modern Harvey units come with an i-Lid sensor system to monitor your salt levels remotely. Download the myHarvey app on your mobile device.
Scan the unique QR code printed under the i-Lid label or enter the DSN/SSN manual codes.
Pull the red battery tab to activate the sensor and hold down the sync button until the blue light flashes to pair with your local WiFi. 🚀 Commissioning and Testing
Once the installation is physically completed, you must commission the system:
Slowly Open Valves: Slowly open the inlet and outlet valves and close the bypass valve. Check carefully for any weeping or leaks around the hoses and bypass block.
Manual Regeneration: Insert a flat-head screwdriver into the manual override button located under the cover. Press and slowly turn it clockwise by one full circle until it pops back up. Let the unit drain for Add Salt and Water: Put
of water into the cabinet for the initial operation, and load the unit with your Harvey block salt.
Note: It may take anywhere from a few days to a week for the completely soft water to completely displace the residual hard water resting in your home's thermal hot water tanks. What specific fitting kit size ( ) do you plan to use for your plumbing setup? Harveys water softener installation manual
