A weep hole used in reverse, which drains water from inside the structure to the outside, preventing outside groundwater from entering the structure!
The KM-type weep hole is a drainage pipe equipped with a backflow prevention valve. Traditionally, it has been used to drain excessive groundwater into drainage channels. The 'KMVM type' has reversed the installation direction of the valve compared to conventional designs, allowing water within the structure to drain outside while preventing external groundwater from entering the structure. This is a KM-type weep hole for troughs. 【Nominal Diameter Lineup】 ■φ40 ■φ50 ■φ75 ■φ100 *For more details, please refer to the PDF document or feel free to contact us.
