## Long description

The Alca plast A434 sink trap is a space-saving syphon designed for under-sink installation in kitchens and bathrooms. With a 5/4" connection thread and a DN40 outlet diameter, this white trap provides reliable water sealing and effective waste drainage while occupying minimal cabinet space. Its compact geometry is compatible with standard fittings and helps maintain accessible storage under the sink.
Advantages
The A434 combines a compact footprint with a standard 5/4" inlet and DN40 outlet, allowing straightforward connection to common sink fittings and waste pipes. The white finish resists visible staining in typical indoor environments, and the simple construction facilitates cleaning and maintenance. Its space-saving form factor reduces interference with plumbing or cabinet interiors while preserving full siphonic function and backflow protection.
Suitable for
Domestic kitchen sinks where under-sink cabinet space is limited
Bathroom washbasins with standard 5/4" connections
Replacement of existing compact traps with DN40 outlet systems
Installations requiring a visible white finish that matches sink or cabinetry
Key specifications
Connection thread: 5/4" compatible with standard sink fittings
Outlet diameter: DN40 for common waste piping
Configuration: space-saving compact trap for under-sink mounting
Color/finish: white
Function: provides water seal to prevent sewer gas and directs wastewater to drainage
How to use
Install the trap directly under the sink outlet, aligning the 5/4" threaded inlet with the sink tailpiece and connecting the DN40 outlet to the waste pipe. Tighten fittings to ensure a watertight seal, taking care not to overtighten plastic threads. After installation, run water to check for leaks and verify that the trap retains water to form the required seal. Access the trap for periodic inspection and cleaning by loosening the removable connections.
Usage recommendations
Use appropriate sealing tape or approved gaskets on threaded joints where recommended, and avoid aggressive chemical cleaners that can degrade plastic components. For best results, inspect connections after a few days of operation and re-tighten if minor leaks appear.
