FAQs
Can the AAV malfunction and what are the signs?
Yes. Any AAV can malfunction or not operate properly because it is a mechanical device. Signs of that the Sure-Vent is not operating as intended, are foul odors. If you smell foul odors (sewer smell) near a plumbing fixture which has a Sure-Vent installed, this means the Sure-Vent is not closing properly to create a positive seal and should be replaced. Some individuals relate slow drains to the Sure-Vent not operating properly. The Sure-Vent is not the issue, the slow drain is related to a partial blockage within the drain itself. A partially blocked drain will fill with water when the fixture is draining, and the Sure-Vent recognizes the positive pressure from the restriction and stays in closed position to stop backflow out of the Sure-Vent. You should have your drain cleaned when this occurs.
Can the Sure-Vent be used to vent a sealed sump pit with waste grinder pump?
Yes, with exceptions. Always check with your local building officials to confirm this application is approved in your municipality before attempting this installation. We also recommend that you check with the pump manufacture before completing this installation. Remember that you also need to vent any fixture or group of fixtures, check with your local building official to ensure your plumbing system is designed properly before installation. If they are not vented properly the drains will not flow properly. After confirming all parties involved approve this application, you can contact our customer service department and they will be happy to send out a drawing explaining the application.
