Sound after Water Drains from Kitchen Sink
We had been smelling an unpleasant odor around the kitchen sink area for a few days before discovering a broken pipe under the kitchen sink. The pipe that was broken was the one on which the vent was mounted. We replaced a section of the broken pipe and the vent. Now, when we fill the sink and then drain it, as the last bit of water is being drained there is a whiney sound/whistle made by what we believe is the vent. A couple of people have said this sound is "normal." However, we have had our current coach for 1 1/2 years and the previous vent never made that sound when water was being drained. One of the two occupants of the RV still thinks there is an unpleasant odor around the sink, so I'm wondering if perhaps the new vent is bad, or there's another problem yet to be discovered. Thanks in advance for any advice.
