Storm drain check valves are important in ensuring that water does not back up into homes or buildings, resulting in flooding. They help to prevent flooding and reversal of flow by closing the valve. They are the cheapest form of backpressure control available. Unlike other types of valves, storm drain check valves do not need to be maintained, and they do not require a power source to operate.
Storm drain check valves are easy to install. They are also inexpensive, and most homeowners do not need to hire a plumber to do the installation. However, if you are unsure of the proper way to install one of these devices, you may want to hire a professional.
There are many different types of storm drain check valves on the market. Some are designed for manual use, while others are automated. The automatic models can be operated by a remote switch. They are cost-effective and customizable, depending on the situation.
Rubber duckbill check valves are the best choice for a number of applications. They are very durable, can handle large obstructions, and are resistant to organic contamination. They can handle raw water and seawater, making them a great choice for a variety of wastewater systems. They are also suitable for Combined Sewer Overflows (CSOs).
Ball check valves are typically used for anti-flooding applications. The minimum pressure required to open a check valve is called cracking pressure. In order to install these valves, you must have a static head of at least 20 feet. This means that there must be enough water in the drains to create an opening in the pipe.
Backwater valves are another type of check valve, and they are designed to prevent backup in a sewer system. They are usually installed on the building drain. They are ideal for areas where there is a high risk of sewage or septic backup. They are also effective in preventing backups from other areas. They are most commonly used in sewage pump stations, but are also effective in applications where viscous liquids are involved. They can be equipped with storm drain check valve hydraulic cushions, spring-assist closing, or other accessories to prevent slamming.
Some municipalities have passed bylaws making these devices mandatory. When a municipality implements this policy, they can avoid liability for backflow of sewage into residential buildings. They can also prevent flooding and other health risks.
Backwater check valves are also commonly used in the municipal sewage system. They can also be installed on roof runoff drains. They are designed to prevent sewer and septic backup from outside the building. These are often the best options for protecting your property, but you will need to consult with your local municipality to find out if it is possible to install these devices in your home.
A good tip is to install a check valve in a place where it will be easily accessible. Some of these valves can be under the floor, in which case you will need to install removable panels to make access easier.
