Hello,
When we had our 2-year old house built, we had the basement roughed-in for a full bath and bar sink.
The bath rough-in seems to have the tub and WC drains wet vented to the lavatory drain which is capped off with an AAV.
The bar sink drain is also capped off with an AAV.
It's time to finish the basement and my question is, is it ok leaving the AAV's for the vents, or do they need to be tied in to the rest of the house vent system?
Both AAV's will be in undersink cabinets, so will be accessible. Local code allows the use of AAV's as long as there is at least one normal vent to the outside.
The rest of the house is vented normally with multiple roof vents.
I'm willing to accept the risk that if one of the valves malfunctions that there would be sewer gas smell until it was repaired. Would there be an explosion risk as well?
Thanks in advance for any advice...
