Can air ingress a dripping water pipe?

Yes, air can ingress a dripping water pipe, particularly if there are gaps or leaks in the pipe fittings or joints. As water drips, a change in pressure can create a vacuum effect that draws air into the pipe. This can occur in both pressurized and non-pressurized systems, potentially affecting water flow and causing issues like air locks. Proper sealing and maintenance of the pipe system can help prevent air ingress.
