Is it allowed to pour boiling water (pasta) in kitchen sink and toilet?

Post by Oombongo » Sun Jan 23, 2022 6:45 pm

Title says it all.

The apartment is new (constructed in 2021), and wondering if it is alright to pour hot water right in kitchen sink or toilet? There is no mention of it in apartment guidebook, and internet is rather divided over it (don't do it, do it and it cleans pipes, yada yada).

How it is in Finland?

The kitchen sink is the natural place to pour the boiling water after cooking pasta or potatoes, and it is designed for that.

Toilets and bathroom sinks are made of different material, they are not designed to handle boiling water and might break.

You are wrong, in the sense that you can do this without a problem.

Water from the tap is designed to be up to 80°C, this is so close to 99°C (boiling water you just take off the stove so it stops boiling) that the materials used for the bathroom sink and toilet must comply with structural safety regulations so it can withstand boiling water, otherwise they would not be allowed to be sold with a CE mark on it (and therefore not allowed to be used in construction).

It's a different thing to occasionally pour a few liters of hot water down the kitchen sink than to run a continuous stream of hot water (as could happen in e.g. some industrial process) let alone steam through plastic pipes. The former might result in faster deteoriation of plastic pipes and/or rubber seals, over many many years, but it definitely won't immediately cause problems. If one wants to see what might happen, try boiling a piece of plastic sewer piping.

Thanks. This has resolved my confusion :)

what are the alternatives? Pour it out of the window? Drink it? Collect it in your bath tub and have a bath in it?

Probably best to let it cool a bit before drinking it, for sure.

Run cold water from the tap while pouring it into the sink. Unnecessary, IMO.

But you'd need to run cold water through pasta for better taste anyway. I always turn on the tap and by the time hot water is gone, the water from tap reaches ice cold level which is perfect for that.
