Used in inspection wells to prevent the accumulation of rain and wastewater in house installations, which may result in basement flooding and similar issues. Two loose rubber rings form sealing and retention of the non-return valve. RIA IKF is manufactured for installation in inspection wells of PVC. Easy installation due to low weight and good resistance to corrosion and the materials used: PEHD and stainless steel.
