Harvey HV3 Water Softener Installation Manual: The Complete Setup Guide

The Harvey HV3 is a popular, non-electric, twin-tank water softener known for its reliability and compact design. Whether you have acquired a unit secondhand or misplaced your original paperwork, having a clear installation guide is essential for ensuring your system runs efficiently and protects your home from limescale.

This comprehensive guide serves as a manual to help you navigate the installation process, from site selection to the final commissioning of the unit. Pre-Installation Requirements

Before you begin the physical installation, ensure you have the necessary tools and the correct environment for the softener.

Location: The unit should be placed on a flat, level surface. Common locations include under the kitchen sink or in a utility room.

Access: Ensure you have easy access to the main cold water pipe and a suitable drain point.

Protection: The softener must be protected from freezing temperatures and direct sunlight.

Tools Needed: Pipe cutter, adjustable wrenches, PTFE tape, and various plumbing fittings (typically 15mm or 22mm depending on your pipework). Step 1: Planning the Plumbing Layout

The Harvey HV3 requires a bypass valve system. This allows you to divert water away from the softener if maintenance is required, without shutting off the water to the entire house.

Identify the Main Pipe: Locate where the main water supply enters the building.

Install Bypass Valves: You will need three valves: an inlet valve, an outlet valve, and a bypass valve.

Check Valve: Ensure a non-return valve (check valve) is installed on the inlet to prevent softened water from flowing back into the mains supply. Step 2: Connecting the Inlet and Outlet

The HV3 features clear markings for water flow. Using high-quality flexible hoses is highly recommended to reduce vibration and make the unit easier to move for cleaning.

Inlet Connection: Connect the "In" port of the softener to the mains water supply after the bypass valve.

Outlet Connection: Connect the "Out" port of the softener back into your household's internal plumbing.

Seal Threads: Use PTFE tape on all threaded connections to prevent slow leaks. Step 3: Installing the Drain and Overflow

Because the Harvey HV3 uses a twin-tank system, it regenerates using water pressure. Proper drainage is vital.

The Drain Line: Run a 1/2" high-pressure hose from the drain outlet on the softener to a standpipe or a waste pipe. There must be an "air gap" at the discharge point to prevent back-siphonage.

The Overflow Line: Connect a separate hose to the overflow barb on the side of the cabinet. This should be run through an outside wall so that any cabinet leaks are visible outside, preventing indoor flooding. Step 4: Commissioning the Unit

Once the plumbing is secure, you need to prepare the unit for its first cycle.

Slowly Open the Inlet: Turn the inlet valve slowly to allow water into the tanks. Check for leaks immediately.

Flush the System: Open a nearby cold water tap (one that is connected to the softener) and let the water run until it is clear and free of air bubbles. harvey hv3 water softener installation manual free

Add Salt: The Harvey HV3 uses block salt. Place two blocks of salt into the front compartment. Ensure the salt is sitting on the floor of the unit and is not "bridging" or stuck.

Test for Softness: After an hour of installation, use a water hardness test kit to ensure the water coming from your taps is "zero" grains of hardness. Maintenance and Troubleshooting

The HV3 is designed to be "fit and forget," but basic maintenance keeps it running for decades.

Salt Checks: Check the salt levels weekly. Never let the unit run completely out of salt, as this will lead to hard water entering your pipes.

Sanitization: Use a water softener resin cleaner once a year to remove any mineral buildup or bacteria within the resin beads.

No Power Needed: Remember, the HV3 is non-electric; it counts the gallons used mechanically. If you experience hard water, check for salt bridging or ensure the bypass valves are in the correct "open" position.

Harvey HV3 Water Softener Installation Guide If you’ve recently acquired a Harvey HV3 water softener and are looking for a straightforward guide to getting it up and running, you’re in the right place. The HV3 is known for its twin-tank design and non-electric operation, making it a favorite for those who want soft water without the hassle of programming buttons or managing power cords.

Below is a comprehensive walkthrough of the installation process. 1. Pre-Installation Checklist

Before you start cutting pipes, ensure you have the following essentials: The Unit: Your Harvey HV3 softener.

Installation Kit: Usually includes 15mm or 22mm hoses, a bypass valve, and a drain hose. Tools: Pipe cutter, adjustable wrench, and bucket. Salt: Block salt is specifically required for the HV3. 2. Choosing the Location

The HV3 is compact enough to fit under a standard kitchen sink. However, you must ensure:

Access: You need enough room to lift the lid and slide in salt blocks. Level Ground: The unit must sit on a flat, stable surface.

Drainage: It needs to be within reach of a waste pipe or standpipe. 3. Plumbing the Bypass Set

A bypass valve is crucial. It allows you to divert water away from the softener if you ever need to perform maintenance or move the unit. Turn off the mains water supply. Final Check: Do You Still Need a Professional Installer

Install the inlet, outlet, and bypass valves into your existing pipework.

Ensure the arrows on the valves match the direction of the water flow. 4. Connecting the Hoses

The HV3 uses flexible high-pressure hoses to connect to your plumbing:

Inlet: Connect the hose from your "hard" water supply to the inlet port on the back of the softener.

Outlet: Connect the hose from the softener's outlet port back to your "soft" water internal plumbing.

Ensure Washers are Seated: Hand-tighten the nuts first, then give them a quarter-turn with a wrench to prevent leaks. 5. Managing the Drain and Overflow

This is a non-electric unit, so it relies on water pressure to regenerate.

Drain Hose: Connect the 1/2" reinforced hose to the drain outlet. Route this to a standpipe or an under-sink waste trap. Crucial: Maintain an "air gap" to prevent back-siphonage.

Overflow: Connect the smaller overflow pipe to the cabinet and route it through an outside wall. This ensures that if the unit ever malfunctions, water leaks outside rather than in your kitchen. 6. Commissioning the HV3

Slowly turn on the water: Open the inlet valve partially to allow the tanks to fill without a sudden surge of pressure. Check for leaks: Inspect every joint.

Flush the system: Run a cold tap (ideally the kitchen tap) for several minutes to clear any air pockets and resin dust.

Add Salt: Insert two blocks of Harvey salt into the front compartment. 7. Testing the Water

Once installed, use a total hardness test kit. Your water should now register as "0" or "trace" hardness. If the water remains hard, check that the bypass valve is closed and the inlet/outlet valves are fully open.

Maintenance Tip: The HV3 is "fit and forget." The only thing you need to do is keep it topped up with block salt. When you see the red indicator or the salt levels get low, simply slide in new blocks.


Final Check: Do You Still Need a Professional Installer?

Even with the free manual, the Harvey HV3 is a competent DIY job if you have basic plumbing skills (cutting pipe, fitting compression or push-fit fittings). However, the manual explicitly recommends:

“Installation must comply with Water Supply (Water Fittings) Regulations 1999. If unsure, use a qualified installer.”

Harvey offers a fixed-price installation service – but if you want to DIY, the free official manual is your most important tool.

While we cannot reproduce the entire manual here due to copyright, we can outline the correct sequence. Always cross-reference with your official PDF.

3. Why the HV3 Manual is Tricky to Find

Harvey is protective of the manual for two reasons:

  1. Proprietary Valves: The "Mini" valve used in the HV3 is a complex mechanical marvel. They prefer that only trained engineers open the valve head for repairs.
  2. Warranty: Installing the unit without following the manual precisely (e.g., not leaving a "service loop") can void the warranty.

4. Commissioning the Unit

  1. Turn on Water: Slowly open the main stopcock.
  2. Check for Leaks: Inspect all joints and push-fit connections. Open a downstream tap to flush out air and debris.
  3. Add Salt: Open the lid and place two blocks of block salt into the salt tank.
  4. Prime the System: The unit may go through a cycle automatically upon power-up. Refer to the control head to initiate a manual regeneration if required.

Why the Harvey HV3? A Quick Primer

Before cutting into your pipework, it helps to understand the machine. Unlike single-cylinder electric softeners, the HV3 uses a twin-tank system. While one tank softens your water, the other automatically regenerates using a simple water turbine (no electricity). This means:

  • Continuous soft water 24/7.
  • Lower running costs (no power, less salt waste).
  • Complex plumbing – The bypass and brine tank setup is more involved than a single-tank unit.

Because of this complexity, installing an HV3 without a manual is a recipe for flooding and voided warranties.
