Introduction to Drain Seal
Drain Seal by Fernco is specifically designed to prevent contaminants entering properties/buildings from drains. The EPDM rubber valve, which can be simply retro fitted into a riser pipe, acts as a one way valve allowing waste water to exit the building whilst blocking the return of odours, soapy suds, insects, viruses etc.
The EPDM rubber seal is moulded and designed as an easy to use, self-cleansing, single component device, with the flexibility to allow even low flow rates of waste water through. Furthermore, it provides the benefit of increasing the effectiveness of the water trap it is installed above, by creating an airtight seal which reduces the rate of water loss.
