Description
The 200mm level invert reducer is an underground drainage fitting used to reduce 200mm pipework down to 160mm while helping maintain the correct invert level through the drainage run. It is suitable for foul water and surface water systems where a larger 200mm pipe needs to connect into 160mm pipework.
This Funke HS® level invert reducer is designed for compatible PVC-U underground drainage systems. It is useful on larger site drainage layouts, commercial pipe runs, yard drainage, groundwork projects and repairs where different pipe sizes need to connect cleanly.
A level invert reducer helps keep the pipe base aligned during the size transition. This supports smoother flow compared with a standard concentric reducer where the pipe invert may not line up correctly.
200mm Level Invert Reducer for Underground Drainage
The 200mm level invert reducer is used when reducing from 200mm underground drainage pipe to 160mm pipe. It is a practical fitting for larger foul water and surface water drainage systems where pipe sizes change within the same run.
Because the reducer is designed to maintain the invert level, it helps keep the bottom of the pipe run aligned. This is important for drainage flow and can help reduce unwanted steps inside the pipework.

200mm Level Invert Reducer Connection
This 200mm level invert reducer connects two different pipe sizes in one fitting. The larger side suits 200mm pipework, while the smaller side suits compatible 160mm underground drainage pipework.
Before installation, check the pipe sizes, flow direction and final reducer position. The reducer should sit correctly within the pipe run and should not be forced into poor alignment.
Use suitable pipe lubricant on ring seal joints where required. Make sure all pipe ends are clean before jointing. If pipework is cut to length, make a clean square cut and chamfer the cut edge before fitting. This helps protect the seal and makes the joint easier to assemble.
200mm Level Invert Reducer Installation Use
The 200mm level invert reducer should be installed as part of a properly planned underground drainage system. It is useful where the main run changes from 200mm to 160mm while keeping the pipe invert as level as possible.
Correct bedding and backfill are important around the reducer. The pipework and fitting should be evenly supported so the drainage system remains stable after installation. Poor support can place stress on the sockets and may affect long-term performance.
Always confirm the finished pipe position, fall direction and access requirements before backfilling. Follow the site specification, current UK drainage guidance and manufacturer instructions.
Reducer for 200mm Site Drainage Work
This fitting is a useful product for builders, groundworkers, landscapers and drainage installers working with larger underground drainage systems. It can be used on new drainage installations, pipework extensions, repairs and system alterations.
For best results, use compatible pipe and fittings from the same underground drainage system where possible. This helps keep jointing simple and supports a clean, consistent installation.
This product is not an access fitting. If rodding or inspection access is required nearby, use a suitable access pipe, inspection chamber or rodding point as required by the drainage layout.
