Review SENTROL Bill Trap

The Sentrol 3555-B3 Bill Trap is a high-performance, reliable, and easy-to-install water flow control device designed for use in commercial, industrial, and institutional applications. This bill trap is engineered to meet the stringent requirements of the American Society of Mechanical Engineers (ASME) and the American Water Works Association (AWWA).

The Sentrol 3555-B3 Bill Trap features a unique and innovative design that incorporates a large 3.5-inch (89 mm) diameter inlet and a 2-inch (51 mm) outlet, allowing it to handle higher water flow rates compared to traditional bill traps. The trap body is constructed from durable cast iron, ensuring long-lasting performance and resistance to corrosion.

The trap is equipped with a removable, fine-mesh stainless steel strainer that captures debris and sediment before they enter the trap, preventing clogging and maintaining optimal water flow. The strainer can be easily removed for cleaning or maintenance without the need for special tools.

The Sentrol 3555-B3 Bill Trap also includes an integrated air vent that allows for the release of air and other gases that may accumulate in the trap, preventing water hammer and reducing the risk of damage to the plumbing system.

The trap comes with a factory-installed, chlorinated rubber gasket that ensures a watertight seal and prevents leaks. It also includes a 15-inch (381 mm) long, 1.5-inch (38 mm) diameter discharge pipe for easy connection to the plumbing system.

The Sentrol 3555-B3 Bill Trap is designed to be installed vertically or horizontally, making it a versatile option for a wide range of applications. It is also pre-drilled for easy mounting to walls or floors using the included hardware.

Overall, the Sentrol 3555-B3 Bill Trap is an excellent choice for commercial, industrial, and institutional applications that require a high-performance, easy-to-install, and reliable water flow control device. Its large inlet and outlet, durable cast iron construction, and integrated features make it a cost-effective and efficient solution for maintaining water quality and preventing plumbing system damage.

The Sentrol 3555-B3 Bill Trap is a sewage backflow prevention device designed to protect potable water supplies from contamination caused by backflow from sewage, industrial waste, or other sources. Here are some pros and cons of buying this particular model:

1. NSF/ANSI Standard 61 certified: This means that the device complies with the American National Standards Institute (ANSI) and National Sanitation Foundation (NSF) standards for drinking water system components.

2. Durable construction: The Sentrol 3555-B3 Bill Trap is made of brass and stainless steel, making it resistant to corrosion and rust.

3. Easy installation: The device comes with a factory-installed check valve, making installation simpler and quicker than some other models.

4. Effective backflow prevention: The Bill Trap design provides a physical barrier to prevent backflow, making it an effective solution for protecting potable water supplies.

1. Limited flow rate: The Sentrol 3555-B3 Bill Trap has a limited flow rate of up to 10 gallons per minute (gpm), which may not be sufficient for larger commercial applications.

2. Higher cost: Compared to other backflow prevention devices, such as atmospheric vacuums or double check valves, the Sentrol 3555-B3 Bill Trap may be more expensive.

3. Requires regular maintenance: The Bill Trap design can accumulate debris and sediment over time, which can affect its performance. Regular cleaning and maintenance are necessary to ensure proper function.

The Sentrol 3555-B3 Bill Trap is an effective and reliable solution for protecting potable water supplies from backflow in residential and small commercial applications. Its NSF/ANSI certification, durable construction, and easy installation make it a popular choice among plumbing professionals. However, its limited flow rate and higher cost compared to other backflow prevention devices may be disadvantages for larger applications or those with more significant budget constraints.

Based on the pros and cons outlined above, the Sentrol 3555-B3 Bill Trap is recommended for residential and small commercial applications where a reliable, effective, and compliant backflow prevention solution is required. For larger commercial applications or those with higher flow rates or more significant budget constraints, other backflow prevention devices, such as atmospheric vacuums or double check valves, may be more appropriate.
