HOT WATER INSTALLATION ESSENTIAL
Complete Hot Water System Valve Kit
A new hot water system is a major investment, so the valves and connections used with it matter. A complete hot water valve kit brings together the key components required to help manage water pressure, isolate the system, control backflow and provide appropriate pressure relief.
Rather than relying on old valves from the previous hot water system, a new valve kit provides fresh components to complement the installation of your new unit.
For customers adding installation, the valve kit can also be supplied with up to 2 metres of installed pipework to help produce a neat and practical finished installation.
Hot water valve kit at a glance:
designed to provide the key valves and connection components required around a compatible hot water system installation. Depending on the installation, this can include pressure limiting, isolation and non-return protection, expansion control, connection components, insulation and a temperature and pressure relief valve where one is not already supplied with the new heater.
WHY IT MATTERS
Why Install a New Valve Kit With a New Hot Water System?
Think of the valve kit as the supporting hardware around your hot water system. The heater may be brand new, but retaining old, worn or unsuitable valves can undermine the quality of the overall installation.
The correct valves help manage incoming water pressure, allow the hot water system to be isolated when required, control the direction of water flow and provide pressure-relief functions where applicable.
Installing a new hot water system? Using new, suitable valves at the same time helps avoid building a premium new installation around ageing components from the system being replaced.
WHAT'S INCLUDED
What's Included in the Hot Water Valve Kit?
Pressure Limiting Valve
The Pressure Limiting Valve (PLV) helps control excessive incoming water pressure before it reaches the hot water system.
Correct pressure control can help protect the heater, valves and associated plumbing from unnecessary stress caused by excessive supply pressure.
Non-Return Isolation Valve
The Non-Return Isolation Valve combines important flow-control and isolation functions.
It helps prevent reverse water flow while also providing a means of isolating the water supply to the hot water system when servicing or maintenance is required.
Temperature & Pressure Relief Valve
The Temperature and Pressure Relief Valve (TPR) is an important safety component designed to relieve excessive temperature or pressure from a compatible storage hot water system.
This is included where the required TPR valve is not already supplied with the new hot water heater.
Cold Water Expansion Valve
The Cold Water Expansion Valve (CWE) provides a means of relieving pressure associated with thermal expansion on compatible installations.
This can help reduce unnecessary pressure stress within the hot water installation.
Connection Set
The connection components provide the fittings required to connect the compatible hot water system into the home's plumbing installation.
Correct connections are important for producing a secure and serviceable installation.
Insulation Kit
Pipe insulation helps reduce unnecessary heat loss from hot pipework and protects relevant exposed sections of the installation.
Proper insulation contributes to a cleaner finished installation and helps retain heat where it is needed.
WHAT EACH COMPONENT DOES
How Does a Hot Water Valve Kit Support the System?
Controls Water Pressure
The pressure limiting valve helps prevent excessive incoming supply pressure from being applied to the hot water system and associated valves.
Provides Isolation
An isolation valve allows the water supply to the heater to be shut off when servicing, replacement or maintenance work is required.
Controls Reverse Flow
The non-return function helps ensure water travels in the intended direction rather than flowing backwards through the incoming supply.
Provides Pressure Relief
Applicable relief valves help manage pressure conditions within compatible hot water installations and form part of the system's safety controls.
Supports Secure Connections
New connection components help ensure the heater is connected using suitable fittings rather than automatically relying on ageing components from the previous system.
Reduces Pipe Heat Loss
Insulation around appropriate hot pipework helps reduce heat loss and contributes to a more complete finished installation.
NEW SYSTEM, NEW COMPONENTS
Why Replace the Old Hot Water Valves?
When an existing hot water system is replaced, some of the surrounding valves may already have spent years exposed to water pressure, temperature changes and normal wear.
Reusing older components can leave ageing valves attached to an otherwise brand-new hot water system. Installing new suitable components gives the new heater a fresh supporting valve setup and allows the installation to be configured around the requirements of the replacement system.
- Fresh valves for the new hot water installation
- Appropriate pressure management where required
- New isolation and non-return components
- Expansion control where applicable
- New connection components
- Insulation for relevant pipework
PRODUCT SUITABILITY
Who Should Add a Hot Water Valve Kit?
Replacing an Existing System
A valve kit is particularly relevant when replacing an older hot water system and you do not want to retain ageing valves and connection components from the previous installation.
Installing a New System
For a new installation, the valve kit provides supporting components required to connect and protect the system according to the needs of the installation.
Wanting a Complete Installation
It is a practical addition for customers who want the hot water system and its supporting valve components addressed together rather than treating the heater as the only part of the installation.
INSTALLATION BONUS
Add Installation and Receive Up to 2m of Installed Pipework
Add installation to your valve kit and up to 2 metres of pipework is included as part of the installed package.
This helps produce a neat and practical connection between the new hot water system and the existing plumbing while allowing unsuitable or untidy old connection pipework to be replaced where appropriate.
INSTALLATION
What Does the Installed Valve Kit Cover?
Where the valve kit is purchased with installation, the applicable components are fitted as part of the hot water installation according to the system and site requirements.
- Installation of applicable valve-kit components
- Connection to the compatible hot water system
- Up to 2 metres of installed pipework
- Relevant pipe insulation
- Neat arrangement of new connection pipework
- Configuration based on site and system requirements
The exact valves and installation arrangement required can vary depending on the hot water system, manufacturer requirements and existing site conditions.
IMPORTANT TO KNOW
Does Every Hot Water System Use Exactly the Same Valves?
No. The required valve arrangement can depend on the type of hot water system, manufacturer requirements, incoming water pressure and the existing plumbing installation.
Some new storage water heaters may already be supplied with their required temperature and pressure relief valve. In that situation, another TPR valve does not need to be supplied simply for the sake of duplicating the component.
The purpose of the valve kit is to provide the applicable supporting valves and connection components required for the installation.
