I posted this in plumbing, but maybe it belongs here?
We live in a house that is a little over two-years-old and in the last year we have had a noise, when the HVAC is running, of gurgling in our wash machine drain pipe. The HVAC is in the attic directly above the washer and we suspect it drains into that line.
Several times we have gone into the attic, poured vinegar down the drain - followed after 30 minutes with water - and then blown out the line with an air compressor. The gurgling resolves, and then starts again in a few weeks. There is no water in the overflow pan.
We have noted a crack in the PVC elbow that allows a bit of water to pass. We noticed this when we poured vinegar down the drain.
We have also poured vinegar down the washer drain, followed by compressed air.
Appreciate all thoughts! Any ideas?
