Summary: Rocket drains are an essential part of any plumbing system. These drains come in various sizes and materials to accommodate the needs of different systems. In this article, we will discuss the different aspects of rocket drains, including their functions, types, installation methods, maintenance, and troubleshooting.

1. The Function of Rocket Drains

Rocket drains are responsible for controlling the flow of water, waste, and other liquids in plumbing systems. Their primary function is to prevent clogs and backups that can cause damage to the system and property. Rocket drains provide a clear pathway for water and waste to flow out of the system, reducing the risk of flooding or overflow.

Rocket drains also play a role in maintaining the structural integrity of plumbing systems. When water sits stagnant in pipes, it can cause corrosion and rust, leading to leaks or other damage. Rocket drains ensure that water flows continuously and prevents standing water from accumulating in the system.

Additionally, rocket drains act as a barrier between the inside of the pipe and the outside environment, preventing pests and odors from entering the system and causing further damage.

2. Types of Rocket Drains

Rocket drains come in various shapes and sizes, with each type designed to fit specific plumbing needs. The most common types of rocket drains include PVC, cast iron, galvanized steel, and brass.

PVC rocket drains are lightweight and reasonably priced, making them the preferred choice for residential plumbing systems. They are resistant to corrosion and easy to install, making them an ideal option for DIY projects.

Cast iron rocket drains are durable and heat-resistant, making them popular for commercial or industrial applications. They are also more expensive than other types of rocket drains and require professional installation due to their weight.

Galvanized steel and brass rocket drains are commonly used in older homes or buildings. They are known for their durability but can be prone to rust over time.

3. Installation Methods for Rocket Drains

The installation process for rocket drains varies depending on the type of drain, the plumbing system, and other factors. Professional plumbers are typically called upon to install rocket drains, especially for complex systems or larger commercial projects.

For DIY installations, it is essential to choose the right size and material for your plumbing system. The correct angle of the drain is also crucial to ensure that water flows out of the system effectively. It is also important to follow local building codes and regulations when installing rocket drains to ensure compliance with safety standards.

In general, rocket drains are installed below ground level to prevent backflow and allow waste and water to flow out of the system effectively. Depending on the plumbing system’s size and complexity, multiple rocket drains may be installed to accommodate the system’s needs.

4. Maintenance of Rocket Drains

Maintaining rocket drains involves regular cleaning and inspection to prevent clogs or backups from occurring. Over time, debris and other solids can accumulate in the pipes, leading to reduced water flow and even the failure of the system.

One way to maintain rocket drains is to use a plumbing snake or other drain cleaning tool to remove any buildup inside the pipes. Regularly flushing the system with hot water is also recommended to help break down any buildup and keep water flowing smoothly.

If routine maintenance does not resolve the issue, it may be necessary to call in a professional plumber to inspect the system and identify any underlying problems that may require repair or replacement.

5. Troubleshooting Rocket Drains

If issues arise with rocket drains, it is essential to troubleshoot the problem to identify the cause and determine the appropriate solution. Common issues that can occur with rocket drains include clogs, leaks, and backups.

To diagnose a clogged rocket drain, try pouring hot water down the drain or using a plunger to remove any blockages. If the issue persists, a plumbing snake or other drain-cleaning tool may be necessary to remove more extensive clogs. In some cases, a professional plumber may be required to repair or replace the drain.

Leaks in rocket drains can occur when pipes become corroded or damaged. Depending on the size and location of the leak, it may be possible to repair or replace parts of the system. In more severe cases, a professional plumber may need to inspect the system to determine the best course of action.


Rocket drains play a vital role in maintaining the integrity of plumbing systems. They help control the flow of water, waste, and other liquids while preventing clogs, backups, and damage to the system and property. There are various types of rocket drains available, each designed to fit specific plumbing needs. Proper installation, maintenance, and troubleshooting can help ensure that rocket drains continue to function effectively and efficiently for years to come.
