I’ve recently relocated my kitchen sink (and associated dw and washing machine) so it will now discharge directly into the soil pipe under the house. Previously it went out of the wall into an outside drain.
Does this mean I will need to install an air inlet valve? I believe there’s a vent out the roof on the first floor bathroom but it’s not clear to me if that’s enough venting for the whole system.
