blocked kitchen sink

there is a very good drain unblocker sold in Mercadona and Lidls if that will help

I found white vinegar and plenty of bicarbonate of soda does the trick. You may have to keep repeating a few times before it is completely unblocked. Also if it’s not too bad run the hot tap with a little fairy liquid for a while as this should melt any fat or oil that accumulates.

thank you

Thank you Alicia,I have Gary Knowles Plumber sorting it

 out for me now
