It can be used for both the bottom and side wall. It is easy to install because there is no need to align the orientation of the product during construction. The rubber valve, which is essential for water resistance, can be replaced.
The "KMV type" is the most common weep hole (backflow prevention valve) used to prevent cracks, uneven settlement, and uplift in structures due to uplift pressure and scouring effects from infiltrating water or seepage flow. Excessive groundwater pressure pushes the rubber valve up, releasing water into the drainage channel and preventing cracks and uplift in the structure. Additionally, when the water level in the drainage channel is high, the rubber valve closes due to the water pressure in the channel, preventing water leakage and scouring effects. There is a jig for attaching the weep hole to the formwork (for KMV-50 and KMV-75). 【Features】 ■ The length of the weep hole is manufactured according to the specified dimensions based on the thickness of the concrete (approximately 100 units can be shipped the same day with AM order). ■ The structural device is simple, reducing the risk of failure. ■ The rubber valve is supported at the center, so there is no construction directionality regarding which side should face up or the angle during installation. It can be used for both the bottom and side wall. ■ The rubber valve is made of a special synthetic rubber, providing good heat resistance, cold resistance, and weather resistance. ■ The rubber valve can be replaced. Adhesive is applied to the screw holes during installation, eliminating the risk of the rubber valve detaching. *For more details, please refer to the PDF document or feel free to contact us.

| Model number | overview |
|---|---|
| KMVP type・KMVU type | This is a weep hole made with commercially available VP or VU pipes for the pipe section that enters the concrete. It can be connected to commercially available sockets or drainage pipes. |
| Insert Head Specification KMVP type・KMVU type | This is a weep hole made with our product "Insert Type Weep Hole for Vertical Wall KMVC type" for the backflow prevention valve on the waterway side. Please consider this when the "diameter of the existing drainage hole" is smaller than the protruding part (rib part) of KMV type, KMVP type, etc., and the weep hole cannot fit. |
