Harvey Crown post 2020 Installation Instructions

Harvey Crown pre 2020 Installation Instructions


It is important that you select the correct installation kit to suit your pipework and hot water system in your property. This avoids any chance of the incorrect installation kit from restricting through the water softener and therefore within your property.

In U.K homes, generally there are three sizes of pipework measurements, all are the diameter across the pipe and they are 15mm, 22mm & 28mm. Generally Water softeners are installed near where the water enters your property, so please measure the pipework above the main isolation valve.

If you have 15mm pipework and a conventional gravity fed, or indirect, system which has a cold water tank in the loft space and hot water cylinder, then our standard  15mm installation kit would be suitable. We offer two lengths of flexible hose to go between your fixed pipework and the water softener, either 1000mm or 1500mm long.

If you are still on 15 mm pipework but have a combination boiler, or direct type system, then you are better to go with the 15mm High Flow installation kit. This has the benefit of using uprated fittings and connection hoses and ensures that you get full flow through everything and therefore get no restriction on flow to and from  your water softener. We offer two lengths of flexible hose to go between your fixed pipework and the water softener, either 800mm or 1000mm long.

If you have 22mm pipework, then the best choice is one of our 22mm install kits. This is found in nearly all houses built since year 2000 and are generally used on feeding mains fed unvented hot water systems. We offer these kits with either 800mm or 1000mm long flexible connection hoses.

In larger properties then we offer a 28mm installation kit for use with suitable Water softeners where the connection pipework is 28mm diameter. We offer two lengths of flexible hose to go between your fixed pipework and the water softener, either 800mm or 1000mm long.

If you are unsure about any of the install kit choices, then please call us on 0845 10 80 685 or email for clarification.

    Love soft water!

    Posted by Debbie B on 13th Nov 2023

    Had to move out of our house for work to be done. Replaced our water softener and couldnt wait to get back. Had forgotten how terrible hard water makes your skin, hair and clothes feel. Apart from the awful white scale marks on the taps, kettle and shower screen. No brainer - never be without my soft water.

    Very happy - thank you

    I'm very happy with the result, and in addition to the obvious benefits such as lack of limescale and using less soaps and detergents, the dry skin condition I developed when we moved into this area has almost completely disappeared. So once again, many thanks for your help and assistance before, during, and after purchase. I'll certainly recommend your company to friends.
