Anti-Flood Valve Type 0 – Applications and Benefits

The backflow-stop valve is a functional product which is ranked among the best on the market. It is ideal for flood-proofing residences in order to protect them against backflow of water in the sewage system after heavy rains.
Heavy rains sometimes produce so much water, that modern canalization systems get overloaded. Cimatic changes leave some areas unprepared for such amounts of precipitation. This means that the flow of water and sewage in the canalization systems can be reversed. This pushes sewage back into houses, where it originally came from, resulting in heavy flood damage to the property and a giant repair bill to the owner. Low-lying properties are at an even higher risk of this happening.

With one of Napan backflow-stop valves installed on the canalization line, owners can protect themselves and their property from flood damage. Our products are easily mounted ouside properties, for example in inspection wells. This saves time and costs associated with indoor installations. It also prevents water from soaking through the floor if it were stopped right under the house.

Whenever water levels and pressure in the system rise, the backflow-stop valve automatically closes, preventing sewage and water from entering the domestic canalization system.

This product has a proven 100% functionality.

The Napan backflow-stop valve is manufactured in several versions, for installation on all kinds of piping systems and in inspection wells. It can also be equipped with an optional alarm. With this add-on installed, the backflow-stop valve is approved for blackwater-containing sewage.

Because of a large number of available versions, your plumbing professional can help you choose the perfect model for your needs. This unique product is offered at competitive prices when compared with alternative solutions.

This product can be mounted in wells anywhere on the property outside the building, thus saving time and expense associated with alternative products that must be installed indoors, usually under the floor.

The reliability of this product is proven by experience. NAPAN has more then 5000 installations in Denmark, where this product helps to successfully guard properties against flood damage.
