The “Pro-Drain Trap Seal”® is designed as a barrier to minimize trap seal evaporation from a floor drain trap. The trap seal device is designed to open and allow gray water flow to a floor drain and then remain closed in the absence of flow. This device is recommended for application in conjunction with a mechanical trap seal priming device. In the rare event that potable water is not present to replenish the floor drain trap seal then this device may be applied by its self to prevent floor drain trap seal evaporation.
The “Pro-Drain Trap Seal”® device has been tested by an approved ASSE Test laboratory and passed the ASSE Standard #1072 successfully. This product is listed by both IAPMO File #7479 and ASSE 1072, Sections I, II. Copies of listing certificates are available upon requests.
