This step-by-step installation guide for the Harvey HV3 / TwinTec Series water softener provides the full plumbing, setup, and smart integration steps required to successfully install your unit. Harvey water softeners feature a non-electric, twin-cylinder design powered entirely by the kinetic energy of your home's water flow. Because they do not require a mains electrical outlet to soften water, positioning, leveling, and securing proper pressure lines are vital for efficient performance. Pre-Installation Check & Site Requirements Before unpacking your tools, ensure your installation site meets the technical baselines specified by Harvey Water Softeners : Surface: Must be placed on firm, completely level ground. Water Pressure: Incoming dynamic pressure must be between a minimum of 1.7 Bar and a maximum of 6.0 Bar . If your pressure exceeds 5 Bar, install a pressure-reducing valve. Space: Plan enough clearance above the unit to load block salt comfortably through the top cover. Plumbing Loop: If your home features a pre-plumbed water softener loop, it is typically located next to your water heater or main stopcock. Necessary Tools and Materials Pipe cutters or a hacksaw Two flexible, food-grade braided hoses Three-valve bypass manifold kit Non-return check valve Silicone grease for O-rings Adjustable spanners or grips High-pressure drain tube and overflow pipe Step 1: Plumbing the Bypass Manifold A dedicated three-valve bypass system isolates the softener for servicing while maintaining hard water access to the house. Isolate Mains Water: Turn off the main incoming water stopcock and drain the nearest cold water tap. Cut the Main Supply Pipe: Locate the main line after your internal stopcock but before any branches feed your boilers or water heaters. Tee Off External Taps (Optional): If you require an unsoftened garden tap or drinking water faucet, install a tee-junction on the main line before it reaches the bypass manifold. Assemble the Three Valves: Install the Inlet Valve on the incoming hard water pipe, the Outlet Valve on the outgoing soft water pipe, and the Bypass Valve bridging the space between them. Add a Non-Return Valve: Mount a non-return check valve on the inlet pipe to prevent softened water or brine from siphoning back into the water mains. Step 2: Connecting the Hoses to the Softener Lubricate O-Rings: Apply a thin layer of plumbing-grade silicone grease to all hose washers and O-rings to ensure a watertight seal. Verify Flow Direction: Note the molded arrows on the Harvey softener connection manifold. They dictate which port is the inlet (hard water in) and which is the outlet (soft water out). Attach Flexible Hoses: Thread your food-grade flexible hoses onto the bypass valves and connect them to the matching ports on the softener. Hand-tighten first, then finish with a light turn from a spanner. Avoid over-tightening to protect the internal plastic housing threads.

Package Contents Harvey HV3 water softener unit 2 x Braided bypass hoses (typically 15mm or 22mm depending on your plumbing) 1 x Drainage hose (clear plastic tube) 1 x Overflow hose Harvey block salt Tools & Materials Needed Pipe cutter or hacksaw Adjustable wrenches Teflon (PTFE) tape Bucket and towels (for catching spills) Screwdriver Wall clips (to secure drainage hoses) Sanisile or silicone lubricant (for O-rings) Choosing the Location Proximity to Mains: Install the unit as close as possible to the point where the main water supply enters the property. Level Ground: The unit must sit on a flat, stable, and level surface. Drain access: It must be within a reasonable distance of a waste pipe or washing machine drain. Protection: Avoid areas prone to freezing temperatures or direct, intense sunlight. 🗺️ System Layout & Plumbing Diagram The Harvey HV3 relies on a standard three-valve bypass configuration. This layout allows you to isolate the water softener for maintenance without cutting off the water supply to your entire home. [Inlet Valve] │ ───(Mains In)────────┴─────▶[Bypass Valve]─────▶(To House Taps) ▲ │ │ [Outlet Valve] Use code with caution. Inlet Valve: Feeds hard water into the softener. Outlet Valve: Sends softened water into your home. Bypass Valve: Keeps hard water flowing to the house when the softener is turned off or disconnected. 🛠️ Step-by-Step Installation Instructions Follow these steps carefully to integrate the Harvey HV3 into your home's plumbing network. Step 1: Shut Off the Water Supply Locate your property's main stopcock (usually under the kitchen sink or near the water meter). Turn it clockwise to shut off the incoming mains water completely. Open the lowest cold water tap in the house to drain the remaining water from the pipes. Step 2: Prepare the Pipework Identify the section of the main cold water pipe after the stopcock but before any branches to water heaters or kitchen cold taps. Cut out a section of the pipe to accommodate your bypass valve block structure. Deburr the cut pipe edges using a file or pipe de-burring tool to ensure clean connections. Step 3: Install the Bypass Valves Install the inlet, outlet, and bypass valves onto your cut pipework. Apply PTFE tape to all threaded male joints to guarantee a watertight seal. Keep the inlet and outlet valves closed , and open the bypass valve. This allows you to turn the main water supply back on to check for leaks in your new plumbing joints without flooding the unconnected softener. Step 4: Connect the Hoses to the Softener Locate the inlet and outlet ports on the back of the Harvey HV3. They are marked with arrows indicating flow direction. Lubricate the rubber O-rings inside the braided hoses with a thin layer of silicone grease. Connect the incoming hard water hose to the Inlet port . Connect the outgoing soft water hose to the Outlet port . Hand-tighten the nuts, then give them an extra quarter-turn with a wrench. Do not over-tighten, as this can split the rubber washers. Step 5: Route the Drain and Overflow Lines Connect the clear plastic drain hose to the dedicated drain barb on the softener. Secure it firmly with a hose clamp. Route this hose to a waste pipe, standpipe, or gully. Ensure a minimum 20mm air gap between the end of the hose and the water level in the drain to prevent back-siphoning. Connect the second hose to the overflow connection point on the side of the cabinet. Route this downward through an outside wall so any emergency overflow safely discharges outside. Crucial Rule: Never run the drain or overflow hoses upward by more than 1 metre above the base of the machine. 🚀 Commissioning and First-Time Start-Up Once everything is securely connected, you are ready to pressurize and test the system. 1. Flush the Lines Keep the softener bypassed initially. Turn on the main stopcock and let a cold tap run for two minutes to clear any debris or copper filings introduced during the pipe cutting. 2. Pressurize the Softener Slowly open the Inlet valve on the bypass block. Allow water to fill the first cylinder of the Harvey HV3 gradually. You will hear water moving through the unit. Slowly open the Outlet valve . Close the Bypass valve . The house is now running on water directed through the softener. 3. Check for Leaks Examine all joints, hose connections, and the base of the unit for any signs of weeping or dripping water. Tighten connections slightly if necessary. 4. Add Salt Open the front lid of the Harvey HV3 and slide two blocks of Harvey water softener salt into the designated slots. The unit requires block salt to function correctly; do not use granular or tablet salt. 🔧 Technical Specifications & Troubleshooting Specification Model Harvey HV3 Control Type Non-electric, volumetric water meter Cylinder Design Twin-cylinder (continuous soft water) Salt Type Required Block Salt Maximum Flow Rate Up to 80 Litres per minute Inlet/Outlet Size 3/4" Male thread / Push-fit options Common Troubleshooting Issues Water remains hard after setup: Ensure the bypass valve is completely closed and the inlet/outlet valves are fully open. Check that the unit has salt blocks installed. Water leaking from overflow: This usually points to a high-pressure issue or a stuck float valve inside the brine tank. Check that your home water pressure does not exceed 6 bar. Install a pressure-reducing valve if necessary. Salt blocks aren't dropping: Ensure the blocks aren't wedged tightly against the sides of the casing. They must slide freely downward as they dissolve.
