The Environmental Protection Agency (EPA) holds local water suppliers responsible for maintaining a certain level of purity in the potable water supply. Therefore, state regulations and local municipalities require backflow preventers to be installed in most types of commercial properties. Backflow preventers are commonly placed at each cross-connection point found within the plumbing systems of apartments, condominiums, food establishments, and most public and commercial places. The type of backflow preventer installed will be in line with the degree of hazards present at the premises. Check with your local municipality for their Backflow Prevention Program, also commonly referred to as Cross-Connection Plan Requirements.

Water pressure is one of the most critical measures of your home’s plumbing health. Not only is high water pressure damaging to so many components in your home, but sudden changes in pressure can be signs of other problems that need to be addressed. But how can you keep a watchful eye on your water pressure Here at Moen, we know all about the importance of pressure. Our Flo Smart Water Monitor and Shutoff works by constantly measuring the pressure in your home’s water network in combination with the flow rate and area temperature. Not only that, it even performs daily automatic Health Tests, which are pressure loss tests on the entire supply line to detect a leak as small as one drop per minute.

Water pressure is huge for the health of your home plumbing network. And while a high-pressure shower might feel great in the morning, water pressure can (and often does) get too high. Any sort of high water pressure will put stress on your home in a number of ways.

Keeping the water pressure in your home at a safe level can help keep your pipes, fixtures and appliances safe. Pressure regulators help reduce high water pressure coming from your municipal supplier, but sometimes they need to be adjusted to either lower or raise your water pressure. Knowing how to adjust your pressure regulator and keeping a close eye on your home’s water pressure will help you protect your home.

As far as plumbing jobs go, adjusting your water pressure regulator is pretty easy. You don’t need too many tools, and you can finish the task in less than an hour. If you experience a sudden drop in pressure, you might want to check in with the local water supplier and see if the problem is on their end before you make any adjustments.

An air gap is a nonmechanical approach to backflow prevention. It creates a physical separation between the water supply pipe and the vessel. It is the most common backflow preventer and necessary to prevent any contaminant or pollutant from being siphoned or pushed back into the potable water supply.

Backflow preventers can be complex and are best thoroughly inspected by a plumbing professional or a certified backflow prevention inspector. However, it’s important for the commercial property inspector to be able to identify common devices and assemblies in order to accurately note them in the commercial property inspection report. Additionally, if you decide to hire a plumbing expert to inspect the system, you’ll need to be able to understand their report to add it to your client’s final commercial property inspection report.

If the property has a backflow preventer, an inspection tag should be attached to the device or assembly. The tag is a record of the date of the last inspection of the system and the name of the person who performed it. If a tag isn’t present, note this in your inspection report. The backflow prevention inspection should be completed by a certified backflow prevention inspector. This professional is also responsible for submitting the required paperwork to the local government office; therefore, you can verify that the system’s inspection is up to date by contacting the local governmental office.

Before you start adjusting the pressure regulator, get an accurate reading on your home’s current water pressure. Attach a pressure gauge to any hose spigot and take note of the reading.

Next, locate the water pressure regulator. Look for a “bell shape” that’s close to your water main and sits on top of the pipe. On top of the regulator should be an adjustment screw and a lock nut. The adjustment screw raises and lowers the water pressure, but before it can be adjusted, you need to loosen the lock nut below it.

Pressure regulators are important because most municipal water suppliers pump water at very high pressures — often four or more times higher than your home can handle. That’s because municipal water sometimes has to service high-rise buildings, high-elevation neighborhoods or fire hydrants.

And since it connects to your wireless network, you get up-to-the-minute alerts no matter where you are. As soon as something out of the ordinary comes up, you’ll get a notification. The Shutoff will even close the water main automatically if it detects a leak to help prevent water damage.

Generally, the installation and maintenance of backflow preventers are handled by property owners. If your client is a tenant and you need more information about the backflow prevention system, contact the property owner or manager. Alternatively, you can hire a specialty consultant. Taking these extra measures will ensure that the system is properly maintained in accordance with the state’s and local municipality’s requirements. It’s essential for the health of the building’s occupants and customers.

Like most plumbing components, your water pressure regulator isn’t going to last forever. The average pressure regulator has a lifespan of about ten years. The question is, when do you need to replace it?

Water pressure regulators are devices that are installed near your water main. They take high pressure water flowing from a municipal water supply and lower the pressure to a level more suitable to homes and their fixtures. Any home built after the 1980s should have a pressure regulator already installed.

The chamber is maintained at a pressure that is lower than the water supply pressure, but high enough to be useful downstream. Four test cocks are installed to allow the inspector to verify proper operation of the valve with a differential pressure meter. Two valves (one before and one after the RPZD) are provided to allow for testing and repair. Although compatible with both above-ground and below-ground installation, above-ground is more common.

Backflow preventers are excluded from the CCPIA’s Standards of Practice, but a commercial building inspector should note whether one is present at the subject property. You may also want to discuss with your client about expanding the scope of the inspection to include further evaluation of the property’s backflow preventer.

Water hammer, which is a banging or hammering noise in your pipes, is a common sign that your pressure regulator is nearing the end of its lifespan. The noise happens when high-pressure water suddenly stops in your pipes, literally hammering into the pipe walls. You’ll probably notice water hammer after you shut off a fixture or flush a toilet.

Water pressure regulators, or pressure reducing valves, are an important part of your home’s plumbing system. They help keep the water flowing through your pipes at a regular, consistent pressure. You might find that the pressure in your home is too high or too low and are wondering how you can adjust the pressure yourself.

A double-check valve is designed for use in non-health hazard cross-connections and continuous pressure applications subject to back-pressure or back-siphonage incidents, such as lawn sprinklers, fire sprinkler lines, commercial pools, tanks and vats, and food cookers. Double-check valves (DCV; also called double-check assemblies or DCAs) are a good choice for underground or indoor installations. A DCA consists of an inlet shutoff valve, two independently operating spring-loaded check valves (usually inside a single valve body), four test cocks, and an outlet shutoff valve.

It consists of an inlet shutoff valve at the bottom, a single valve body consisting of a pressure vacuum breaker, a check valve, two test cocks, and an outlet shutoff valve. Some pressure vacuum breakers also offer built-in freeze protection; however, this only protects the PVB assembly. Inlet and outlet pipes can still freeze if the system isn’t properly winterized.

If you notice regular fluctuations in pressure and have to frequently adjust the regulator valve, it’s probably time to start looking for a replacement. Having a new water pressure regulator professionally installed will set you back a few hundred dollars. But it’s a worthwhile investment considering the risks of leaks, pipe bursts and appliance failure that can result from a faulty regulator.

In this article, we’ll go over how pressure regulators work and why it’s so important to have one that works properly. Then, we’ll give you an overview of the adjustment process so you can tweak your home’s water pressure to your liking.

During the research portion of the inspection, the commercial property inspector can ask questions that might reveal evidence of backflow. For example, in an interview or pre-inspection questionnaire with the person(s) with the most knowledge (typically, the building’s owner, manager, or your client), ask:

Although water contamination is often evident through taste, smell, or discoloration, sometimes it’s far less noticeable.

Backflow preventers, also known as backflow devices and assemblies, are installed to prevent backflow, which can contaminate the potable water supply.

Loosen the lock nut by half a turn with the crescent wrench. Turn the adjustment screw counterclockwise to lower the pressure or clockwise to raise the pressure. Only go one full revolution at a time and get a new pounds per square inch (PSI) reading with your pressure gauge. Once you’ve reached your desired pressure level, tighten the lock nut on the pressure regulator.

A backflow preventer is required to be installed at most commercial properties. It prevents the contamination of the potable water supply. Backflow preventers are excluded from CCPIA’s Standards of Practice, but the commercial building inspector should note whether one is present at the subject property. You may also want to talk to your client about expanding the inspection’s scope of work to include a thorough evaluation of its installation because a backflow preventer is vital for protecting the health of the building’s occupants and customers. A thorough evaluation of the system could include hiring a certified backflow inspector, or contacting your local regulating governmental office.

Backflow preventer devices and assemblies can be found above ground, below ground, or housed within the building itself. In some cases, a commercial property may be exempt from the installation of a backflow preventer. If the subject property doesn’t have a backflow preventer and your client would like to verify if the property is exempt from this requirement, contact your local municipality or government office to verify the property’s exemption status.
