What is an AB air gap?
The AB Airgap is designed to prevent the inlet to become submerged and stop the water within the tank contaminating the mains water supply should there be a backflow pressure drop in the mains.
What is a Category 5 break tank?
A Cat 5 break tank is a water tank featuring an air gap between the inlet and outlet to ensure that the water in the tank or cistern does not flow back into the mains water supply and meet the relevant Water Regulations requirements for Category 5.
What is a break tank for fire protection?
Break Tanks are water storage tanks installed upstream of a domestic (potable) and fire water pump system to interrupt or “break” the connection between the pump and the water source. To provide water storage to augment a water source that cannot provide the maximum flow rate required.
How does a break tank work?
The break tank appliance works by feeding the incoming mains water supply into a separate tank first. This separate tank has an ‘air gap’ (a simple opening at the top that acts as an overflow). From this tank, water is then fed into the dishwasher.
What is the purpose of an air gap?
This gap is usually about the distance between the faucet and the top of the sink or bathtub (one inch or more). Basically, the air gap is there to prevent accidental backflow. If contaminated water backflows, it can cause serious health risks. Without the air gap, wastewater could siphon back into the drinking supply.
Why does a water softener drain need an air gap?
Air gap fittings are plumbing code required to mount in the drain line(waste line) of water treatment equipment and their primary purpose is to prevent non-potable water from flowing backwards possibly mixing and contaminating potable (drinking) water.
What is a CAT 5 break tank and booster set?
What is a CAT 5 booster set? A CAT 5 booster set is a booster set with a break tank that complies with current fluid category 5 regulations and is complete with an AB air gap. The booster set is designed for connection to the mains water supply and provide backflow protection against a category 5 fuild.
What is a CAT 5 pump?
Cat 5 pump and tank sets have two main uses – they help to provide category 5 compliance with the Water Regulations (the Act of Parliament that governs what you can connect to your water supply); they also act as a Cat 5 booster set to provide a constant pressure, which is very useful when running pop-up sprinklers or …
What is the use of break pressure tank?
The main purposes of pressure break tank 1 are to break the pressure from the existing collection tank and mediate the flow of this water throughout water areas A, B, and C. The tank is designed to meet short term needs, and eventual long term goals.
How do you size a fire break tank?
Each tank or compartment must be large enough to allow 50% of the demand to be stored. Each tank or compartment must have an automatic refill that can provide the full system demand.
What is a break tank and booster set?
In water distribution, the term break tank refers to a pressureless and closed water tank, with an air gap that ensures zero backflow into the system. Grundfos supplies pumps and booster sets for pressure-boosting in break tank systems for buildings and water supply.
Is an air gap necessary?
Air gaps are the most effective means of preventing your drain from cross-contaminating your dishwasher with waste. If you want to protect your dishwasher from flooding with contaminated water, you need an air gap. Dishwasher air gaps are also required by plumbing codes in many locations.
What is a Category 5 fluid?
Fluid category 5 (CAT 5) is described as a fluid representing a serious health hazard because of the concentration of pathogenic organisms, radioactive or very toxic substances.
What is BPT water?
In summary, BPT prescribes removal of pollutants by physical/chemical treatment that includes chemical metal hydroxide precipitation, physical gravity settling/clarification, and final physical removal of solids, all of which can be accomplished by using simple practical methods.
What is a pressure break?
Pressure Break Tank 1. Overview. The main purposes of pressure break tank 1 are to break the pressure from the existing collection tank and mediate the flow of this water throughout water areas A, B, and C. The tank is designed to meet short term needs, and eventual long term goals.
What is a break tank with pump?
What happens if you don’t have an air gap?

Why do we need an air gap?
What is an air gap break tank?
Air Gap Break Tanks are equipped with their own boosting pump systems to ensure that the proper movement of water is possible and is delivered to the end-user at the necessary pressure that is both comfortable and compliant to code.
What is a break tank?
A Break Tank is a non-pressurized, closed water tank, with an air gap to ensure zero backflow. It interrupts or ‘breaks’ the connection to the water source.
What is a Category 5 air gap in a cistern?
Cistern with Type AB air gap providing Fluid Category 5 protection. Supplied as a complete package, including stainless steel wall bracket – incorporating a drip tray. The primary purpose is to provide backflow protection in accordance with the Water Regulations.
What is a break tank in a water pressure booster?
To create required pressure for taller buildings, break tanks are used to divide the boosting system into multiple pressure zones. In some areas, booster cannot be directly connected to the incoming mains supply to ensure that no water can get fed back into the mains supply, preventing contamination.
