    Q:My Oatey Sure Vent was giving off sewer gas so I've removed it and ordered a replacement. However that will take 7 days. How should I cover that vent area in the meantime? Can I use my toilet?

      Q:I currently have a 160 DFU sure vent on a basement evacuation pump chamber. When I flush the toilet, it fills almost to the top, and drains very slowly into the evacuation chamber. If I remove the vent and flush, it goes down very quickly like the other toilets in the upstairs. To me this appears that there is not enough air being vented quickly. Would going up to a 500 DFU vent solve my problem, and vent enough air quickly? (Or is that not how it works?)

      Answer This Question

      A:  The use of AAVs on an ejector pump application must first be approved by the manufacture of the pump and the building officials within your jurisdiction. If approved by both entities, you must have the drain and vent sized and installed in a very specific configuration. The bathroom group or singular fixture draining into the pit must also be vented properly. The issue that you are describing is related to a venting issue that is common in incorrect venting methods. We would recommend that you reach out to your pump manufacture for details on how to size and install your drain and vent. The reason why the drain flows well when the AAV is removed is related to the release of positive pressure from the system. When an AAV is exposed to positive pressures, it remains closed and water flow is restricted.

        Q:what does 500 dfu mean?
        by|Mar 2, 2018
        1 Answer
        Answer This Question

        A:  DFU - stands for drainage fixture unit. This is a measure of probable fluid discharge into the drainage system by various types of plumbing fixtures. Each fixture's DFU value depends on the volume of fluid discharge per cycle and an average time between cycles. Examples of DFU calculations can be found on our website www.oatey.com in the FAQ section located at the bottom of the home page. Always check with local building officials to confirm these calculations match theirs. The 500 DFU is the size of fixture load that the AAV can vent properly.
