Hi any advice welcome, please recommend a company in sheffield area, I live
in a maisonette high up , downpipe from kitchen sink empties verrry slowly.
Tried three bottles of Domestos drain cleaner , no improvement. Tried
bleach, hot water. A hose pipe goes down about 12 feet till hits 'u' bend.
Will a CCTV survey help and much would it cost? Thanks for any usefull
Can you get at the other end of the pipe, or is it plumbed directly into
If you can, you can temporarily block the pipe up with clean water and
see if the sink level drops overnight. If it doesn't, it should be safe
to fill the whole pipe with cleaner solution and leave it overnight.. If
it does, well, only mostly clean water will have escaped.
Otherwise, it would help if you can identify what other pipes go into
the stack and whether they have problems. The problem may not be in the
sink run at all.
Sometimes the problem just comes down to a badly designed run. I've
known people stick in something like a sanivite pump after getting a
blockage unblocked, rather than get the pipe run redone. Seems to work..
We had exactly the same problem with our soilstack, it wasn't until I
refitted both our bathroom & kitchen that the cause of the problem was
Where our pipework entered the stack, a hard crud had developed ( it looked
& felt like pummice stone). It was created by a mixture of grease, soap
powder & limescale. With the existing pipework removed, I was able to
literally chisel the crud off.
I suffer regulaly from blocked kitchen sink drain caused by build up of
grease. This is not as bad as piles, but that's another storey. Being a
skinflint I am very reluctant to buy things like Domestos drain cleaner but
I did once use some stuff from B&Q which came in a yellow plastic bottle and
it worked a treat.
