There are many advantages to using a storm drain check valve. It prevents backflow and is out of the flow path. It should be constructed of all-rubber materials for durability and easy maintenance. In addition, it should open under low head pressure. The valve should not be obstructed by debris, which can cause damage.
Tideflex
If you’re looking for an effective storm drain check valve, Tideflex is the name to remember. These check valves have a wide variety of applications and can be easily installed. They’re manufactured from Neoprene with an EPDM wrapping. Both materials are extremely durable, and Neoprene has excellent resistance to grease, kerosene, and methane. EPDM has good UV and abrasion resistance. They also pass NSF standards and are suitable for use in clean water systems.
In addition to their innovative Tideflex storm drain check valve, Tideflex has other innovative products for wastewater treatment. Their line of products includes CSO (combined sewer overflow) and SSO (single-point overflow) systems. The company also offers a variety of pinch valves for influent and effluent flow control, fish hatcheries, and sewage treatment plants.
Ball check valves are an excellent option for sewer applications. This storm drain check valve type of valve prevents backflow and has the added benefit of being silent during operation. It is designed with a fully ported valve seat to ensure that the ball seats leak-tight in any position. This makes it suitable for horizontal and vertical installations.
Another benefit of these valves is that they can mitigate flooding caused by high tides and storm surge. These valves prevent seawater from entering storm drains, which can cause flooding in low-lying areas even in sunny weather. In addition to preventing flooding, they also protect salt sensitive vegetation near storm drains.
Backwater valves
Backwater valves for storm drains can prevent the backflow of sewage and other fluids into a basement. They work with a municipal sewer line or a private septic system to prevent overflow, flooding, and other problems. They are important components of any drainage system. Local authorities require that backwater valves be installed. There are also subsidy programs that help with the costs.
Backwater valves should be inspected once or twice per year to make sure that they are in good condition. Cleaning them will help remove any debris or moving parts that may clog the valve. Most backwater valves have a removable cover that can be removed for cleaning. Experts recommend using hot soapy water to clean them. It is also a good idea to wear rubber gloves and use a long-handled brush to clean the valve.
Regulations for installing one
The Regulations for installing a storm drain check Valve include certain requirements for RPZ assemblies. These assemblies must have a minimum of 18 inches of clearance from the floor to prevent submersion and provide access to the relief valve. They must also have at least a 12 inch clear space on either side of the assembly and a 30 inch clearance above the assembly.
The regulation requires that the total fixture load on a combined drain not exceed 256 fixture units. This amount represents the equivalent horizontal drainage area of 1,333 square feet (124 m2). Each additional fixture unit is equal to 5.2 square feet. These values are based on a three-inch-per-hour rainfall rate.
