Telescopic riser for manhole – height adjustment and easy access

This telescopic riser, with a diameter of 300 mm and a height of 250 mm, is a practical solution for distribution and drainage septic tanks. It is designed to facilitate access to devices located in the manhole and allow precise height adjustment to ground level. It is compatible with popular EPURECO W-011T and EPURBIO W-011TG models, as well as W-012 T and W-012 TG.

The riser is made of durable high-density polyethylene (HDPE), which guarantees its resistance to corrosion, mechanical damage and adverse weather conditions. This ensures a long service life, minimizing the need for replacement. The set includes a gasket that ensures a tight connection and protects against the penetration of groundwater and contaminants into the manhole.

Installation and application:

The telescopic riser is easy to install and adjust. Its telescopic design allows for smooth height adjustment, which is especially useful when installing on uneven terrain or when precise adjustment to the surroundings is required. This allows for convenient control and operation of devices located in the manhole without the need for excavation work. This saves installers and end-users time and costs associated with servicing.
