How to Join Twinwall Ducting and Drainage Pipes

Most twin wall ducting products come with a coupler pre-attached at one end. However, it's always good practice to confirm this before placing your order. If you need to connect another length of twin wall ducting, a simple push fit between the coupler and the next pipe will do the job. Just keep in mind that since the coupler doesn't have an internal seal, there might be minor leaks at the connection points. For waste or solvent carrying systems, it’s advisable to add a seal to avoid any potential issues.

To add a seal, choose the right size twinwall pipe seal and position it between the first and second twin wall pipe ribs entering each end of the coupler. This will make the coupler a bit harder to fit, but it will ensure a watertight connection. For systems that handle corrosive or harmful solvents, consider using nitrile seals. These are custom-made and might have longer lead times, but our technical team can help you choose the right option based on your needs.

How to Join Solvent Waste and Soil Pipes

Connecting solvent waste pipes to soil pipes typically uses a 'boss' fitting. This could either be pre-formed in the soil pipe or added as an adaptor during the connection process. If you're using a pre-formed boss pipe section, you'll need to cut a section out of the soil pipe. On the other hand, if you're using a boss adaptor, you just need to cut a hole of the correct size in the soil pipe.

One of the fastest and most popular methods is using a strap-on boss adaptor. Here's a simple six-step guide to get you started:

1. Cut the appropriate size hole in the soil pipe where you want the connection.
2. Clean the area around the connection point with a specific pipe cleaner.
3. Apply solvent cement around the hole and to the flange of the strap-on boss.
4. Make sure the boss' 'top' indicator is facing the correct direction.
5. Push the boss and soil pipe together to ensure a secure bond.
6. Secure the fit by squeezing the clips at the back of the boss together.

Once the solvent cement sets, you'll have a permanent and sealed connection between the solvent waste and soil pipes, ready for additional connections.

How to Join Ring Seal Soil, Waste, and Underground Pipe

Joining ring seal soil, waste, and underground drainage pipe systems is straightforward and quick, allowing for easy disassembly if needed. Each section of the ring seal system has a chamfered end, which should be lubricated with a silicone or water-based pipe lubricant before being pushed squarely and evenly into the fitting. This compresses the rubber seal, creating an airtight and watertight joint.

After inserting the pipe into the joint, pull it back by around 10mm to allow for any future expansion within the system.

How to Join Electrofusion Pipe and Fittings

Electrofusion fittings are commonly used for gas mains and should only be installed by trained professionals with the proper certification. An electrofusion connection also requires a control box, which follows specific operating procedures. While this guide provides a general overview of the process, we're always happy to provide more detailed information and product recommendations. Feel free to reach out to the EasyMerchant team for assistance.

1. Ensure the polyethylene pipes are clean and free from debris but keep the protective wrap intact.
2. Position the electrofusion fitting next to the pipe and mark approximately 10-15mm beyond half the socket depth.
3. Use a pipe end preparation tool to remove the outer layer of the pipe over the marked area in one continuous motion.
4. Repeat this process for the second pipe end.
5. Mark half the coupler depth onto both pipe ends to ensure an even connection.
6. Secure the two pipes in place to prevent movement during the fusion process.
7. Connect the ECU outputs to the fitting terminals and follow the control unit instructions.
8. Check for melted indicators if present, confirming the process is complete.
9. Record cooling times, joint reference numbers, and dates on the pipework.

Upon completion, you'll have a robust, airtight, watertight, and seamless connection.

How to Join Compression/Mechanical Pipes and Fittings

Compression or mechanical pipe connections are widely used in domestic settings due to their affordability and ease of use.

The end body of a compression-style MDPE pipe joint forms a partial dish shape, housing a cone-shaped rubber washer, often topped with a tough plastic washer. Over this stack, an MDPE threaded nut connects to the threaded section of the joint, compressing the washer stack and causing it to expand laterally.

Connecting a compression joint to a pipe is a straightforward process:

1. Clean and deburr your pipe with wire wool to remove dirt and residue.
2. Completely open the nut and washer stack on your compression joint.
3. Slide the nut, washer, and rubber washer onto the pipe you're connecting, ensuring the rubber washer fits tightly and sits at least 15-20mm onto the pipe.
4. Slide the joint body onto the pipe until it snugly meets the rubber washer.
5. Move the washer and nut down the pipe until they cover the rubber washer and bite into the threaded section of the joint.
6. Tighten the nut to compress the rubber washer and create a secure, watertight connection.

Mechanical compression MDPE pipe fittings and joints are easy to install and highly reliable, making them perfect for waste pipes and traps.

Toilet Tank

A toilet tank, also known as a hidden cistern, is a modern plumbing fixture used in bathrooms and toilets. It is designed to hide the flushing mechanism behind a wall or inside a piece of furniture, providing a sleek and minimalist look to the bathroom space.

The main purpose of a concealed flush tank is to save space and create a clean aesthetic by concealing the unsightly plumbing components typically associated with traditional exposed cisterns. By integrating the flush tank within the wall or furniture, only the flush buttons or plates are visible to the user.

Concealed cisterns come in various designs and sizes to accommodate different installation requirements. They are usually made of durable materials such as ABS plastic or stainless steel to ensure longevity and resistance to water damage. The tanks are equipped with a water inlet valve, a flushing mechanism, and an outlet pipe connected to the toilet bowl.

In addition to the aesthetic benefits, installation systems also offer practical advantages. They are typically equipped with dual-flush mechanisms, allowing users to choose between a full flush for solid waste and a partial flush for liquid waste. This dual-flush feature helps in conserving water by reducing the amount used for each flush, contributing to water efficiency and environmental sustainability.

Installation of a concealed cistern requires professional plumbing expertise, as it involves cutting into the wall and connecting the tank to the toilet bowl. However, once properly installed, the maintenance and upkeep of a concealed toilet tank are relatively straightforward.
