Recently, I inspected a house in Ferndale where I noted handyman drain-waste-vent plumbing practices at the exterior. 

The property owner had installed an exposed ABS drain line, and the laundry room utility sink was unconventionally vented adjacent to an exterior wall. A qualified contractor should always evaluate these types of unorthodox issues, which I cited in the report.

If you have questions or comments about plumbing issues or home inspections in general, tweet me (@AIHomeInspect).
