What to Know About Tapers and Taper Bends in Drainage: Usage, Fitting Accuracy, and Supply

Tapered connectors are purpose-built elements used to connect pipes of different sizes in drainage networks. Their role is to ensure a streamlined size reduction, which helps avoid flow restriction, backflow, or leakage. When drainage systems are retrofitted, tapers deliver a more reliable solution than forcing mismatched pipes together.



Why Taper Bends Make Multi-Tasking Simple



Taper bends combine a shift in pipe direction with a simultaneous reduction in diameter. These fittings are most common in angles such as standard elbow degrees, and they’re particularly effective in installations where room is limited or multiple transitions are needed. They limit the number of individual components, helping to lower failure points in the system.



Typical Fitting Locations



These fittings are widely installed across various drainage applications:




  • In pump chambers, to join large outflow pipes to smaller distribution lines

  • Throughout retrofit projects with updated or non-standardised pipework

  • Across field drainage systems where flow rates and gradients must be kept steady

  • Inside wastewater facilities where components need to be space-saving and multi-functional



Correctly applied, these fittings maintain consistent flow, reduce energy loss from turbulence, and help meet regulatory standards for water management.



Importance of Correct Fitting Size



Incorrectly sized joints can cause:




  • Disturbances in hydraulic pressure

  • Blockages from sedimentation

  • Stress on seals and fittings



Tapers and taper bends smooth these transitions out by offering a controlled reduction, improving flow performance and reducing long-term maintenance.



Why Choosing the Right Supplier Makes a Difference



Choosing a general merchant might offer convenience, but a specialist drainage supplier brings:




  • Greater range of product sizes and angles

  • Products designed for field application

  • Product advice from experience

  • Proven quality assurance



A dedicated supplier will have fittings that are not only dimensionally correct but also proven in field conditions—ensuring long-term system integrity.



FAQs



Is a taper the same as a reducer?

No. Tapers feature a longer and gentler size change, which is more effective for systems needing steady flow. Reducers often reduce quickly, which may create turbulence.



Can taper bends be used underground?

Yes, as long as they’re compliant with underground use requirements and follow relevant local guidelines.



Are tapers compatible with clay and plastic pipes?

Tapers are usually manufactured for one pipe type, but adaptors can bridge the gap between clay, plastic, and other pipe materials.



Do taper bends reduce flow performance?

If correctly selected and installed, taper bends maintain consistent flow and can even improve it by avoiding abrupt transitions.



What size taper should I choose?

Measure both ends and factor in hydraulic design to select the correct taper size for the application.



Choose Smart, Fit Once



Whether you're replacing a few get more info components or building a new network, fitting the correct here tapers and taper bends is key to a low-maintenance and efficient drainage setup.
