  1. WRAS Approval

    WRAS Approval

    What Is the Requirement?

    It is a legal requirement that any water fitting or appliance that is connected to, will carry or will receive water from the public mains water supply must comply with the Water Supply (water fittings) Regulations* or Scottish Byelaws.

    Example applications would include commercial appliances such as commercial dishwashers, glasswashers and laundry equipment as these are connected to a mains water supply feed to operate.

    It is the responsibility of a property owner to know which regulations are applicable to their circumstances and ensure compliance. Regulations are typically in effect between the boundary of a property and the point of discharge as illustrated below.

    Who are WRAS?

    WRAS are the Water Board Regulatory and Advisory service. WRAS is a subscription membership of which the subscribers are the 26 UK Water Suppliers. Their purpose is to contribute to the protection

  2. Water Softeners

    Water Softeners

    What Is a Water Softener?

    A water softener is an appliance which removes calcium, magnesium and other ions from water to leave pure, fresh clean water (often referred to as soft water). This resulting water helps to ensure water compatibility with soaps and detergents and extends the lifetime of plumbing and appliances.

    What Is the Requirement?

    Installing a water softener will add protection to any plumbing equipment as it will reduce the amount of calcium deposits and other build-ups such as limescale which can degrade pipework, block joints and generally cause damage or complications.

    This is particularly prevalent with high-pressure systems and those which use heating elements or heat exchangers to heat or cool mains water, for example, kettles, water boilers and ice makers.

    Commercial dishwashers and glass washers are also particularly affected as they use high pressures, heat water and rely on balanced detergent and soap chemicals to funct

  3. Hard Water Areas In The UK

    Whilst we recommend that all appliances fitted to mains water supplies (particularly commercial dishwashers and glass washers) are installed and fitted with a water softener, the extent on which you will rely on your water softener to protect equipment, the frequency at which you are required to regenerate your water softener and the size of water softener you require will largely depend on whether you live in a hard water area or not.

  4. Styles & Sizing of Commerical Warewashing Machines

    This guide is written to introduce the sizing and terminology used to describe the different types of ware washer available on the UK market with the aim of helping you to select which category is best suited to your businesses particular requirements.

    Small Dishwashers (400mm Basket)

    Found In: Coffee Shops, Small Bistro, Office Environments

    Very similar to glass washers, but have a rotating upper wash arm and are generally placed in or on a work surface or in tight spaces. The biggest difference between smaller models and their larger equivalents is a restriction in clear entry height, preventing larger crockery items (such as big dinner plates) from fitting inside the machine door. However, they are ideal for snack plates, side plates and other crockery items such as saucers. They will typically have between a 1 and 4 minute wash cycle time that cannot be adjusted by the machine operator. Ty

  5. Waste Type Options

    Generally there are two types of waste connection available when choosing a commercial ware washer. Choosing between either a gravity waste or a drain pump machine will depend on the requirements of your building and the location you are planning to install the machine.

    Gravity Waste

    Gravity waste machines function by the operator removing a plug from inside the machine wash tank to release dirty water into the drainage and therefore require the waste pipe to be the lowest part of the machine. This can normally be achieved by installing the machine on top of a counter or stand.

    Gravity Waste Diagram

    Pumped Waste

    Drain pump machines function in a similar way to domestic machines in that a pump is activated (either manually or automatically depending on model) at the end of a wash cycle and dirty water is pumped down the drain pump

  7. Break Tanks

    This article aims to provide advice to businesses assessing their requirement for a Break Tank (Type A Air Gap) when purchasing a commercial dishwasher or glass washer, such as care homes, nurseries, day care centers and hospitals.

    Definition of a Break Tank:

    A break tank is often referred to as a ‘Type A’ Air Gap but must not be confused with a ‘WRAS approved non-return valve’ as it provides an entirely different method of operation.  

    What is a Break Tank Dishwasher?

    A Break tank may be fitted to a commercial dishwasher to prevent any possible back flow of dirty water (containing food debris, contaminates, bacteria etc). from the machine into the fresh water mains supply. They are installed into machines to ensure that there is no chance of contaminating fresh water supply.

    How Does a Break Tank Dishwasher Work?

    The break tank appliance works by feeding the incoming mains water supply into a separate tank first. This separate tank ha
