AKA universal long bottom wash elbow DK101 – plumbing connection fitting

AKA DK101 is a universal long bottom wash elbow designed for plumbing installations where an extended connection between a cistern and outlet is required. Intended for use in repair work or new sanitary fittings, this connection fitting provides additional length and alignment flexibility to accommodate varied installation distances and positions in toilet cistern bottom flush systems and similar sanitary applications.

Advantages

The universal long bottom wash elbow offers extended reach and a straightforward connection geometry that simplifies alignment between the cistern outlet and the discharge pipe. Its design reduces the need for additional adapters or pipework when the standard outlet position does not match the soil or waste connection. The fitting is suitable for both maintenance and new installations, providing a reliable, space-efficient solution for constrained or offset installation layouts.

Suitable for

• Toilet cistern bottom flush connections with extended distance to the waste outlet
• Repair and replacement of worn or incompatible cistern outlet fittings
• Sanitary installations requiring offset or angled discharge alignment

Key specifications

• Function: long elbow connection for cistern bottom flush
• Compatibility: designed as a universal fitting for common sanitary outlets
• Application: suitable for repair and new installation work in toilet and sanitary systems
• Design characteristic: extended length to bridge larger distances or offsets

How to use

Install the long bottom wash elbow by aligning the fitting with the cistern bottom outlet and the corresponding discharge or soil pipe. Ensure contact surfaces are clean and any required gaskets or seals are correctly positioned before securing the connection. Tighten connections according to the installation environment and material to avoid overtightening; verify alignment and test for leaks after installation. Use standard plumbing tools and follow local plumbing codes and manufacturer guidance for water-tight connections.

Usage recommendations

Verify compatibility with your cistern outlet diameter and the discharge pipe before installation. Where possible, inspect existing seals and replace them to ensure a reliable watertight joint. If the installation requires additional angle or height adjustments, combine the long elbow with compatible connectors or short extensions designed for sanitary systems.
