How SWR Elbow Fittings Improve Drainage Flow

All pipe and fitting choices must be correct when it comes to creating an effective drainage system. And one of the most important fittings that will be used is the SWR elbow fittings, which is essential to control the way wastewater flows and to make connections around bends, corners and around walls or other obstacles. The correct drainage pipe elbows allow for both the creation of the most practical pipeline design as well as giving you greater control over flow resistance and directional change.

What Are SWR Elbow Fittings?

SWR (Soil, Waste and Rainwater) elbow fittings are pipe fittings used for redirecting the flow of drains or drainage pipelines. These types of SWR pipe fittings are most often made of UPVC (Unplasticized Polyvinyl chloride) and used for SWR systems for managing the soil, waste, and rainwater. The UPVC SWR fittings join up with pipes of the same or similar material at various angles in order to make a suitable layout of the drainage system according to the application. SWR elbow pipes fitting come in various sizes and configurations for different scenarios such as rainwater drainpipes, bathroom waste outlets, kitchen drainpipes, or vertical soil stack pipes.

How SWR Elbow Fittings Affect Drainage Performance

The profile of SWR elbow fittings determines a direction of waste water into a drainage pipeline. In the event of the pipe bend, there is a localized obstruction which results in eddies forming. The nature of these is a function of the angle and radius of bend as well as internal surface characteristics of the pipeline as a whole. A gradual bend causes flow disruption to a lesser extent than an abrupt change of direction. This benefits the flow of the wastewater as it travels through the fitting network.

The direction of SWR pipe bends and elbows is another factor that influences the overall quality of the performance. When using the correct pipe gradient and installing joints, bending in the right direction can help to maintain a flow of the drainage. Misaligned bends and incompatible fittings could cause build-ups and blockages.

45° vs 90° SWR Elbows: Which Is Better for Drainage?

Both of these elbows have their place in drain installation. The 45 degree SWR elbow allows for a much smoother transition whereas the 90 degree SWR elbow allows for a bit of a sharper bend. The decision will likely be dependent on your pipeline configuration and your drainage needs.

45-Degree SWR Elbows for Gradual Direction Changes

Ideally used for drainage arrangements where the pipeline bend is a slow change of direction. The bend is at an angle and this can reduce some of the local flow resistance vs the sharp bend depending on fitting geometry and is commonly used where a gradual change in direction is needed. A number of 45 degree SWR elbow bends can be used to create larger directional changes and offer some flexibility in pipe direction change.

90 Degree SWR Elbow For Small Drainage Layouts

SWR elbows are used to bend a drain pipe at a 90 degree SWR elbow. They are perfect for installing into tight areas around walls, corners and other obstacles. They allow room for space restrictions, joining horizontal and vertical drain sections, and for pipe routing but may increase the localized flow resistance on sharper bends and should be designed with the system layout and size and access for servicing in mind.

Where Are SWR Elbow Pipes Commonly Used?

SWR elbow pipes are a very common form of pipe used in various applications within the plumbing industry. Its ability to change the direction of pipelines makes it useful across many plumbing applications. Here are some of the common uses of SWR elbow pipes: 

• Vertical soil stacks: Linking sections of piping and navigating around the changes of direction in building drainage systems.
• Sewer line: Located underneath, carrying waste from hand wash basins, showers, etc.
• Rainwater downpipes: Pipes which distribute or take rainwater from the roofs.
• Kitchen drains: Methods for the part of the water lines and drain pipes to get water surrounding the walls.
• Commercial drains: To look after the plumbing systems in hotels, offices, and other commercial & institutional buildings.

When appropriate SWR pipe bends are used, an efficient drainage plan and well-attached length of pipe are achieved.

Key Factors When Selecting SWR Elbow Fittings

Before selecting SWR elbow fittings, you need to check the following product specifications and installation requirements. Here are some: 

• Matching the diameter: Always select the fitting of the same diameter as the drainage pipes that you are connecting.
• Bend angle and bend radius: Depending on the direction change and position of the pipeline bend 45-degrees or 90-degrees.
• Choosing the right size: Determine connection depth and size of the installation area.
• SWR pipe Jointing type: Check if the application is for ring-fit or self-fit connection.
• Pipe slope: Ensure the correct slope that allows wastewater to flow by gravity.
• Material quality: UPVC fittings should have uniform measurements, appropriate strength and proper finishing.
• Standards used: Review the product standards associated with the pipe selected and the scope of work associated with your project to ensure it is suitable for the type of drainage which will be required.

These factors help plumbing businesses, plumbers and plumbing contractors select the right fittings to remove the problems faced during installation.

Common SWR Elbow Installation Errors

Even high-quality SWR drainage fittings can be compromised through faulty installation. There are some typical errors that should be steered clear of in the plumbing:

• The installation of elbows the wrong way during installation might cause additional disturbances in the flow.
• Poor joint cleaning and preparation (causes of poor connections and leaks)
• When pipes aren't aligned properly, this creates unnecessary pressure on fittings, and can even have an impact on the duct's balance.
• No water movement: Wastewater and solids build-up in misaligned pipes and hindered slope.
• Poor cleanout access. Trash can't be accessed or inspected if you have a lot of obstructions in the line.
• If the elbow is a different size to the pipe or jointing system, it won't fit.

This annoyance can be reduced by installing as per the manufacturer's instructions and check-out of the connections.

FAQs

Here are some of the common SWR elbow fittings FAQs that buyers need to know before placing an order. 

Q1. Are 45-Degree SWR Elbows Better Than 90-Degree Elbows?

Not necessarily. For gradual bends a 45 degree SWR elbow is preferable, where for quick changes of direction a 90 degree SWR elbow is better. Which one you use is dependent upon pipeline shape, space and drainage needs.

Q2. What Sizes Are Available for SWR Elbow Fittings?

SWR elbow fittings to suit drainage pipe sizes. Flowtek Pipes & Fittings supplies our listed UPVC SWR elbow range in a variety of diameters for SWR elbow pipe sizes from 40 mm to 160 mm (product availability varies).

Q3. Can SWR Elbow Pipes Be Used for Rainwater Drainage?

Yes. Rainwater drainage includes UPVC SWR elbow pipes to alter the downpipe position and connect areas of pipework in various positions. The fitting is essential to rainwater drainage and has specific size and fitting requirements to complement the drainage design.

Q4. What Is the Difference Between Ring-Fit and Self-Fit SWR Elbows?

Ring fit SWR elbow incorporates a sealing ring to form a joint between suitable pipe and fitting connections. Self fit SWR elbow will have a socket connection for use with the associated jointing method. The required installation method and suitability may vary, so always refer to manufacturer instructions.

Q5. How Can Incorrect SWR Elbow Installation Cause Blockages?

Inappropriate elbow choice, bend shape, improper pipe alignment and slope all upset the flow of the wastewater or collect debris at their edges. Inadequately prepared joints can form obstructions inside the pipe. Correct fitting selection and installation can reduce these drainage issues.
