Question about washing machine pipes

    I don't have a dishwasher and just had my house remediated for Pyrite. When I was plugging my washing machine back.in I noticed that there was 2 white water pipes facing upwards where the water travels and I presume one of these is earmarked for a dishwasher. Just wondering would I need a blocker to stop water flowing out of the unused tube when I use the washing machine? Don't want to flood the house.

    These are drain pipes?

    If there's one not in use, I would fit a cap as it could be a source of odours.

    Water won't flow out of these. They're just drain pipes that probably go into a gully outside.

    It's generally not a great idea to leave them open to dry out as they've (usually) got a U bend trap at the bottom which should remain full of water.

    If they're out of use permanently you should fit an airtight cap.

    You can pick up a waste pipe blanking plate in a plumbing supply shop and they just screw on. If you subsequent install dishwasher, all you have to do is remove it.

    Fitting a cap is even more important if the drain pipes run directly into a sewage system which would be likely in an apartment as they need to maintain water in their trap.
