The outflow p-trap from my washing machine is clogged. How can I remove the p-trap, which is glued PVC?

Hi CG24

You can't. You either remove the cleanout on the bottom of the trap and snake through that, or you cut the pipe, snake the drain and then use a repair coupling or a shielded clamp to join everything back up.

You could also snake down the washer vent pipe if you have a flat roof... ;)
