How to Install an AccuBoost Accumulator Vessel
For homes that suffer with low mains water pressure or flow, installing an accumulator vessel can be an easy and effective way of improving the water performance of taps, showers, baths, and other outlets across the house.
Our AccuBoost range includes accumulators suitable for unvented cylinders or combi boilers and has been designed to be easy to specify and install.
An accumulator vessel installation may seem like a daunting task, but it doesn’t need to be! We’ve developed a range of resources to guide you through every step in the process from specification to installation. In this guide we provide a step-by-step explanation of how to install an accumulator vessel.
Select the location
AccuBoost vessels can be installed in various locations, including kitchen cupboards or in the garage, anywhere it can be connected to the mains water supply.
AccuBoost accumulators can be ‘teed’ in anywhere in the system, but only outlets that are after the non-return valve will see the benefit.
Unbox AccuBoost
Unbox the product and read through the installation guide. The installation guide should always be your first port of call, it provides you with a pre-installation checklist, product descriptions, technical specifications, and step-by-step instructions.
Turn off the mains
Turn off the home’s mains water supply and then drain down the system.
Make provision for the mains cold feed
Once drained, make a provision for the cold mains to be taken to the AccuBoost vessel.
Install valves
Next, you’ll need to install the necessary valves.
You will need to install a double-check valve, then a pressure reducing valve before the AccuBoost unit. A maintenance bypass should also be fitted.
We recommend fitting an inline strainer after the stop tap, to allow the system to retain the built-up pressure.
Create a connection to the mains
For AccuBoost models, create a direct connection between the mains supply and the AccuBoost vessel.
Set the pressure
AccuBoost accumulator vessel models pressure need to be set at 1.5 bar less than the natural mains pressure.
See our FAQ’s page to learn how to check the pre-charge pressure of an accumulator tank vessel.
Turn the stop tap on
Turn the stop tap back on and open the isolation valves to allow water in to the AccuBoost.
Results
The mains water pressure and flow around the home should now be noticeably improved.
