Blocked sink

[Margaret]

Bah! my sink is blocked.
I tried the plunger, for about a half an hour, then I resorted to put caustic soda, down, still didn't work.
I managed to get a plumber for tomorrow around lunch time. So I can't wash up the dishes at present.

[Lex]

Hope you get it sorted quickly Margaret!

I always have a flexible strip for these events. I can't remember where I got it from, but it wasn't expensive and has paid for itself times over.

If the plumbing is plastic you can often disassemble it yourself and wash the obstruction out in another sink.

I had a blocked washbasin.I soaked out the water and poured caustic crystals down the plughole and put the plug in.In the night I heard it clear-- loudly. The liquid caustic was useless.

Thanks Lex.

Rebbonk,
The plumbing under the sink is plastic, the connections are so tight, but I don't really want a sludgy mess, I suspect it might be the washing machine outlet as well because there was a few bits of lint came up when I was plunging. I was knackered after half an hour plunging.


Cathy,
I think you are right, the liquid solution did nothing, though the water has slowly trickled away, but there is still a problem. I was thinking of just putting the caustic soda direct down the plug and leaving it but I followed the suggestions on the container, It says 50grams of crystals to a litre of water, well I didn't have a measure for 50 grams, so it was guess work. I'll be glad to get it sorted today.
Next time Cathy, I'll try your suggestions. If there is a next time.

Ah, you have the same system as me by the sound of it. - Washing machine connects to the sink U bend.

I find one of the problems is that the washing machine filter can get blocked (Who ever cleans it? - I do now!) and cause issues, the other surprise I found was that washing powder (and some liquids) can also cause blockages, especially if you use the low temperature stuff. Our washing machine now gets a "maintenance" run every 6 weeks on a hot cycle with nothing in it. I find it clears all the residues.

Something else I found recently...

Our washing machine had developed a little bit of a 'whiff'. It turned out to be stagnant water lying in the sump at the bottom of the machine. (Again, made worse because of the low temperature washes). I discovered that our machine had a "drain" function to be used when the wash was finished. This emptied the sump and we've had no more issues.
