If you're working on a plumbing project that requires the use of SWR pipes and fittings, it's important to know how to properly join and connect them to ensure a secure and leak-free installation. In this guide, we'll take a look at the steps you need to follow to join and connect SWR pipes and fittings. Before we begin, it's important to understand what SWR pipes and fittings are. SWR stands for Soil, Waste, and Rainwater, and SWR pipes and fittings are used in plumbing systems to carry sewage, waste, and rainwater away from buildings. These pipes and fittings are made from PVC (polyvinyl chloride), a durable and lightweight material that is resistant to corrosion and chemical damage.  

Step 1: Planning the Pipe Route

Before you start the installation process, it is essential to plan the pipe route. The pipe route should be such that it provides a slope for easy flow of water. A slope of 1:40 is recommended for PVC SWR pipes. The slope ensures that the water flows freely without any obstruction, reducing the chances of blockage.  

Step 2: Cutting the Pipe

Once you have planned the pipe route, the next step is to cut the SWR pipe to the desired length. Use a hacksaw or a PVC pipe cutter to cut the pipe. Make sure to cut the pipe straight and remove any burrs on the cut end.  

Step 3: Cleaning the Pipe

Before you join the SWR PVC pipes and fittings, it is essential to clean the pipes' ends. Use sandpaper or a file to remove any burrs or rough edges on the ends. The ends should be smooth and clean to ensure a proper connection.  

Step 4: Applying Solvent Cement

Solvent cement is used to join the SWR pipes and fittings. It is essential to use the right type of solvent cement recommended by the manufacturer. The solvent cement creates a chemical bond between the pipe and the fitting, ensuring a strong and leak-proof connection. Apply the solvent cement to the pipe and fittings mating surfaces, making sure to cover the entire surface. Do not apply too much cement, as it can cause the joint to weaken.  

Step 5: Joining the Pipe and Fitting

Once you have applied the solvent cement, join the pipe and fitting. Make sure to insert the pipe into the fitting's socket and twist it slightly to ensure a proper fit. Hold the pipe in place for a few seconds to allow the solvent cement to set.  

Step 6: Checking the Connection

After joining the SWR pipes and fittings, it is essential to check the connection for any leaks. Allow the solvent cement to dry for at least 24 hours before running water through the pipes. Check the connection for any leaks or signs of water dripping. If you notice any leaks, reapply the solvent cement and join the pipe and fit it again.  

Step 7: Installing the Pipe

Once the pipe is inserted into the fitting, it's time to secure the joint. There are a few different methods you can use to do this, including solvent welding and rubber ring joints. Solvent welding is a process that involves using a solvent to chemically bond the pipe and fitting together. This is a permanent bond and is often used in applications where the joint will be exposed to high levels of stress or pressure. Rubber ring joints, on the other hand, use a rubber ring to seal the joint between the pipe and fitting. This is a less permanent option but is often easier to install and can be more cost-effective.  

Step 8: Testing the Plumbing System

After installing the SWR pipes and fittings, it is essential to test the plumbing system. Run water through the pipes to check for any leaks or signs of water dripping. Check all the connections and joints for any leaks. If you notice any leaks, reapply the solvent cement and join the pipe and fit in again.  


Proper installation and connection of SWR pipes and fittings are essential for the efficient functioning of the plumbing system. Follow the steps mentioned above to join and connect SWR pipes and fittings properly. Always use the right type of solvent cement recommended by the manufacturer and check the connections for any leaks. By following these steps, you can ensure a strong and leak-proof connection, reducing the chances of blockage and damage to the plumbing system.  Checkout our Facebook Page for more content Oriplast
