Backflow Preventers: An Overview

In short terms, a backflow preventer is designed to let water flow in one direction. Its sole purpose is to prevent contamination of drinking water caused by backflow occurrences. Backflow is a term used in plumbing for water flowing in the wrong direction, leading to serious health issues.

The preventer can be installed in a building or an underground vault but usually above ground. The best choice is not building but that it is above ground.

How A Backflow Works

In some situations, water can flow backward into the main water supply line caused by pressure buildup in the pipes. Contaminated water can move back into a municipal water supply or another location in your home. Commercial and industrial locations usually have 3 taps for fire protection, domestic, and landscape irrigation. Each one of the lines might or might not be equipped with a contaminant backflow prevention assembly within a given property.

Where Should A Backflow Be Located?

The safest and most inexpensive area to install a backflow preventer is inside an above-ground enclosure located outside. You will have great protection for your backflow preventer as well as easy access when needed. You do not have to be concerned about your building flooding if backflow happened because it will operate as it's designed to.

Installing a backflow preventer underground is a bad idea, It can lead to the property owner facing liabilities and unnecessary risks. Toxic gasses can leak into the vault and there's a possibility animals could set up shop leading to a dangerous situation when it's time to test or repair the equipment.

What Are The Installation Options?

There are 3 avenues for backflow preventer installation โ€“ inside a vault, inside a building, or an enclosure that is outside and above ground. You should refer to the backflow preventer installation guide that covers all three options and will point out that placing the backflow preventer outside and above ground is the best choice and option.

A subterranean vault is still considered the best approach that is still practiced by some designers to date. Whether you know it or not, an RPZ cannot be installed below grade. Even though there are reasons why an RPZ is not suitable for installation below grade, there are reasons why the use of vaults should be discontinued altogether.

Here are reasons why a vault should not be used:

Vauts can cause cross-connections.
Vaults are defined by OSHA as confined spaces.
Backflow preventers are created to stop cross-connections from taking place.
Backflow preventer installation in a vault is counterproductive because vaults can flood.

Over the years, we have heard from various jurisdictions and testers across the country. A poll was conducted for engineers and water jurisdictions were asked about vaults during a webinar on backflow preventer installation. 70% said they know vaults flood.

A flooded vault can lead to a cross-connection through submerged test cocks both open and closed. A backflow assembly has test cocks and shut-off valves and must be tested at least once a year especially when installed, relocated, or repaired.

For further information, you can research online and read the opinions of experts on the subject.

FCCCHR said vaults could fill with water and you might wonder how that happens.

As stated earlier about vaults, OSHA believes utility vaults are considered confined space. Each year when backflow in the vault is tested, the tester must climb down into the confined space. According to the National Institute for Occupational Safety and Health, 92 fatal injuries take place each year in confined spaces. You might wonder why trained professional testers don't know how to manage confined spaces. What happens with maintenance personnel, property owners, and even kids snooping around? It's simple for anyone to open the lids on these vaults and climb in and many testers agree There never seems to be any posted signs of Danger at or on these vaults.

You can research and read online why backflow preventers should not be allowed in below-grade vaults.

Choosing Your Enclosure

Things you should know about choosing an enclosure The enclosure's manufacturer must be in compliance with the ASSE 1060 standard. This will guarantee the enclosure is strong and long-lasting. Also, it has a locking device, good drainage, and will maintain the right temperature for your climate.

There are 3 classes to choose from ASSE 1060 approved enclosures providing different levels of protection from contaminated water and the elements. You should get a Class One enclosure with the required heating system for protection from freezing. There are several materials available so you can choose what will work best for you.

The most common materials for backflow enclosures include aluminum, fiberglass, and cages. There are also enclosures on the market made of brick and block to check out.

Choose the ASSE 1060 enclosure in the material of your choice and get the strongest protection for your project. You can also choose the color and size you are looking for. Safe-T-Cover enclosures come in 4 different colors at no added charge, including a green and tan to blend with your landscaping. There are other colors to choose from with an added fee so you can customize your enclosure.

Also, the size of the enclosure can vary along with the type such as the N-type backflow preventer which has a smaller footprint and will be smaller than the enclosure for an inline backflow preventer. Both the color and size can blend into the landscaping of your project. You can place the enclosure close to the property line just not at the front entrance which could be an eyesore.
