SERVICING 

3.1 

MAINTENANCE AND CARE OF YOUR EQUIPMENT 

The AquaTech‐Pressmain equipment that is described in this instruction booklet has been manufactured and 
tested to the highest standards of design and quality. It will give trouble free operation over many years provided 
it is maintained regularly from when it is commissioned. To keep it operating efficiently in a safe, economical and 
environmentally friendly condition, regular maintenance is an essential part. 

 

AquaTech‐Pressmain along with its’ service division, Acorn Pressurisation Services are the official providers of 
commissioning and maintenance services. (see below).  
Several companies operating under the Aquatronic Group Management structure are available to fulfil a wide 
range of servicing and maintenance requirements, as detailed below. 

3.2 

LEGAL REQUIREMENTS 

Hydraulic Accumulators/Expansion Vessels installed as part of/in conjunction with this equipment, with Pressure 
x Volume above 250 Bar‐litres, require formal inspection in accordance with a “Written Scheme of Examination”. 
This is a Legal Requirement on the part of the Owner/User under the “Pressure Systems Safety Regulations” 
(PSSR). A “Written Scheme” and regular inspection can be provided by either Acorn Pressurisation Services 
(combined maintenance and inspection) or ESIS Ltd (inspection only), see details below.

Acorn provides maintenance and installation of all types of packaged water pumping equipment for building services. Its 
specialist fields are Pressure booster equipment and sealed systems for heating and chilled water distribution systems. 
Regular servicing of any plant for essential services is vital because wear and tear are very gradual processes. 
With preventative maintenance, the costs are small and benefits in reliability, safety and economy can be significant. Acorn 
Pressurisation Services can provide a complete package of schemes for preventative maintenance on all AquaTech‐Pressmain 
and other makes of equipment.

Under the Pressure Systems Safety Regulations, expansion vessels and hydraulic accumulators, generally 250 bar‐litres and

Insurance Services Limited specifications can provide the means to comply with these regulations. These services can be
