Attention all school building engineers and lab building engineers — do your laboratories utilize vacuum breakers? Vacuum breaker lab faucets offer extra functionality and usage to your water systems.

Backflow risk refers to the potential of dirty water entering your potable water supply. If this were to happen, your potable water would be at risk for contamination. Of course, the goal of proper plumbing is to maintain the sanitation of potable water — especially in high-tech areas like school laboratories. To minimize risks associated with backflow, it's imperative to consider the installation of backflow prevention devices. Custom laboratory faucets and fittings, including vacuum breakers are a great way to reduce your chance of contamination.

Installing new laboratory faucets and fittings is important for any school, hospital, or research lab. Laboratories conduct research and demand precise results. Therefore, it's necessary to equip your lab space with top-of-the-line appliances. Vacuum breakers enhance lab faucets in many ways. First, they reduce the possibility of contaminating public waters with harsh chemicals that could be used in your lab. In fact, most cities have regulations regarding the water that flows out of laboratories and into public systems.

So, you can rest assured that your lab is doing its due diligence to avoid any contamination. Additionally, choosing faucet fittings with satin antimicrobial SAM finishes will reduce and protect against the spread of bacteria in your own lab.

By decreasing bacteria, you can trust that your lab faucet fittings are working to decrease bacteria present in the water you may use for lab projects. When installing a vacuum breaker, the water supply must be completely clear. Flush your water supply line prior to installation to avoid any debris that could foul the vacuum breaker, prevent proper sealing, or damage components of your new lab faucet system. Vacuum breakers are usually installed as a part of a lab faucet gooseneck.

However, vacuum breakers can also be incorporated between remote control water valves and outlet fittings. All vacuum breakers must be installed at a level position and atmospheric vacuum breakers should be placed downstream from the final valve in the water supply line.The Buy American Act is a complex government regulation which could require legal assistance to understand fully.

More often than not, the water is coming from the spout, which means you'll have to disassemble the faucet, remove the valve and replace the washer.

If the faucet is leaking from around the handle, that's a different problem, but you still have to take apart the faucet. Finally, an outdoor faucet may be leaking from the vacuum breaker, a circular cap on the top of the faucet just behind the handle, and that's the easiest repair of all.

The vacuum cap is circular and about an inch in diameter, and it either slips or screws onto the top of the faucet. The device underneath it is known as a vacuum breaker or an anti-siphon valve. How would a vacuum develop inside a faucet the first place? That can happen for more than one reason. The supply pipes for most exterior faucets tie into a cold water main that also supplies water to other parts of the house.

Suppose demand is unusually high one day. Perhaps you have guests, and two showers are in use at the same time while the washing machine is operating, and someone is running water in the kitchen. The extra demand creates a heavy flow in the main supply pipe, which, in turn, creates suction in the branch pipes that aren't being used, including the exterior faucet. If the faucet doesn't have an anti-siphon valve and a hose is attached, the vacuum transfers all the way to the nozzle, which may be lying in the mud.

It could draw dirt and sediment into the hose through the nozzle, which could end up contaminating the water system. The anti-siphon valve prevents this by closing whenever the water is off and preventing water from flowing backwards.

The vacuum breaker is a simple device that basically consists of a diaphragm and a watertight chamber. When the water is on, water pressure forces the diaphragm down, opening the valve and allowing the water to flow. When the water is off, a spring or the force of atmospheric pressure forces it back against the water inlet, forming a seal that prevents any water from flowing backward. If a vacuum develops in the water line, it only serves to strengthen the seal. When an outdoor faucet is leaking from the vacuum breaker, it's usually because the diaphragm seal or the spring mechanism has worn out.

These are inexpensive parts, so there's no point in trying to repair them, although you probably could if you wanted to. It's much easier to simply replace them, and that's what most people do. Siphoning is a common problem with drip systems, because the drip components are in constant contact with the ground. When water leaks from an anti-siphon valve, it tends to dribble onto the ground, but sometimes it sprays. If so, you'll want to do the repair quickly.

Here's how:. Some anti-siphon valves come as attachments that you screw onto the faucet spout.

When one of these leaks, simply unscrew it and replace it.To avoid contamination of the fresh water supply, it's critical that no dirty water is allowed to be drawn back siphoned into the water supply system. This can be especially problematic in outdoor faucet spigots sill-cockswhere a garden hose may lie on the ground or in water puddles.

Should a sudden drop in pressure somewhere in the water supply pipes occur, dirty water can be sucked back into the pipes through the garden hose, thus contaminating your home's fresh water. Some anti-siphon devices are available for situations in which a hose may be left dangling from a faucet—such as outdoor garden spigots or a faucet in laundry washrooms.

Most other applications have no such need since the faucet spout is a located a safe distance from any drain water. These anti-siphon devices are essentially one-way valves designed to stop the flow of potentially contaminated water back into the drinkable potable water supply.

Anti-siphoning capabilities are required by code on certain plumbing devices, such as exterior faucets sill-cocks or utility sink faucets.

Anti-siphon devices protect against the possibility of a low water-pressure event in the supply line sucking contaminated water back into the potable water supply. Exterior faucets sill-cocksanti-siphon protection eliminates the chance that a garden hose immersed in contaminated water or attached to a chemical sprayer can draw contamination back into the water supply system. Today's plumbing codes require that the outdoor faucet is of a special type that includes an anti-siphon mechanism as an integral part of the faucet itself.

The anti-siphon device can be a vacuum breaker or an air gap; this fitting is usually located in front of the handle portion of the faucet.

These special faucets also keep freezing cold temperatures away from the water supply pipe. The faucet head is attached to a 6- to inch-long stem, and at the end of the stem there is a fitting allows for connection to a threaded, soldered, or PEX tubing water supply line. On these faucets, the valve itself is located at the back end of the long faucet stem, inside the house itself. This means that the valve is never subjected to freezing temperatures and cannot freeze and rupture, as old-style outdoor faucets are prone to do.

For indoor faucets, such as those on laundry utility sinksit is technically illegal to leave a hose attached to the faucet so that it lies in the bottom of the sink. However, this is very often done anyway, and for these situations, you can buy a vacuum breaker attachment that screws onto the end of the faucet spout. When a hose is attached to the threaded end, the fitting provides anti-siphon protection by allowing air instead of contaminated water to suck back into the pipes when a negative pressure event occurs in the water supply system.

The same spout attachment that is used on indoor utility sink faucets is sometimes used on outdoor faucets, as well, when the faucet does not have built-in anti-siphon protection. Technically this is not allowed by Code—a true anti-siphon faucet is required—but such faucet spout attachments do somewhat protect the outdoor faucet from contamination, and may be an interim solution until you can install an approved anti-siphon faucet.

Outside spigots, utility sinks and other spots around homes and businesses pose the risk of contaminated water flowing back into the plumbing system.

A vacuum breaker is a simple plumbing fixture that can prevent that potential contamination to increase your water safety. A vacuum breaker is one of several devices designed to prevent water that leaves the faucet from flowing back into the plumbing system. Vacuum breakers do this by preventing backflow and back siphoning from occurring. Any place where water is supplied for any use other than drinking water needs a vacuum breaker installed. State and federal laws require vacuum breakers be installed on outside spigots, commercial dishwashing machines, mop-sink faucets, and dish sink sprayer hose spigots.

Water supply lines usually maintain enough pressure to prevent water from flowing back into the pipe. But if a pipe bursts or is disconnected for some reason, that pressure can drop and allow contaminated water to flow back in and mix with the clean water. Any faucet or spigot not connected to a vacuum breaker can allow water to seep back into the spigot if the pressure on the supply side decreases.

Contaminants from ground water and microorganisms could contaminate the potable water. Back siphonage can occur when there is extreme demand on one part of the water supply, which can cause negative pressure in other parts of the system.

For example, a facility might have two mop sink areas and a dishwashing machine. None of the spigots are protected by a vacuum breaker and it's a busy day in the dish room. The dishwasher is being used a lot, and as a result, there's negative pressure on the pipes supplying water to the mop sinks. The negative pressure causes the hose lying in the mop sink to pull the dirty water in the bottom of the mop sink back into the hose where it contaminates the fresh water.

A sink vacuum breaker prevents this from happening. A hose bibb vacuum breaker is a threaded device that screws onto the spigot mouth. It prevents water from flowing backward into your pipe with a spring loaded check valve.

This valve opens and closes based on the water pressure. When the water flows, the pressure of the water pushes open the check valve in the hose bib backflow preventer. When you turn off the water, the pressure against the spring on the valve decreases, the valve closes, and air flows into the space around the valve. The air pressure and the spring keep water from seeping back into the spigot from the outside. Atmospheric vacuum breakers are the simplest and least expensive of devices intended to keep water from flowing back into the water lines.

They operate by using the outside air pressure to close a check valve. When you turn on the water, the water pressure pushes open the water valve. When the water is off, the air pressure pushes down on the valve and blocks the pipe. Atmospheric vacuum breakers must be installed at least 6 inches above the spigot with piping from the vacuum breaker to discharge the water.

The water flows through the breaker and into the spray hose. This type of vacuum breaker is often installed on commercial dish sink hose sprayers and on water supply lines for commercial dishwashers. The pressure type vacuum breaker is a modification of the atmospheric vacuum breaker. It's intended for use in situations where the water supply is under pressure or the valves are downstream of the breaker. The pressure type vacuum breaker contains a spring loaded poppet and two test cocks.

Gauges attached to the test cocks allow the pressure to be constantly monitored.
