Washing machine floods our bathroom sink

Just Starting Out

Washing machine floods our bathroom sink

We have just moved into a rental apartment with no laundry, so the washing machine drainage is connected to our bathroom sink pipes. Any time we do washing it almost overflows our sink, and takes ages to drain. We have used “draino” to unclog the sink, and have disconnected the pipes to look and doesn’t seem like a clog anywhere. My partner seems to think the pipes are too small to handle the amount of water going through them from the machine.






 Wondering if there’s an easier fix or if we should call a plumber?

Re: Washing machine floods our bathroom sink

Welcome to the Bunnings Workshop community @rubymae03. It's wonderful to have you join us, and many thanks for your question about connecting a washing machine.


It could be a combination of issues. Your pipework might just be capable of draining the water, but if it becomes slightly blocked, backfilling into the bowl occurs. Does your sink drain freely when the washing machine isn't in use? Typically, if all the pipes are flowing correctly, you might expect some bubbles into the bowl, but it really shouldn't be filling to the top and almost overflowing.


It sounds like you might need a plumber to come in and take a look. It would be best to notify your property manager and let them know you're concerned the overflowing bowl might cause water damage to the surrounding area.


Please let me know if you have any questions.
