My drain from the kitchen to the main drain is blocked. It looks
like it’s down to hard fat … AGAIN……….

Last time, I removed the fat by putting on a long glove and putting
my hand down the drain and then up the u bend and scraping the fat
with a piece of old electric cable from an old shower. This worked,
but was especially nasty when I got some of the drain water up my
glove.
Despite telling swimbo not to wash fat down the kitchen drain the
drain is blocked again. Not wanting to repeat the experience I made
the mistake of believing the guy in the diy store when they
recommended a chemical to pour down the drain to clear the fat,
despite several attempts no luck. Subsequently I have added 1KG of
caustic soda, still nothing.
My problem is now I don’t have the option of putting my hand down
the drain. What can I do?
I tried jet washing from the man hold last time to no avail. All I
can think of is digging up the patio and drilling a hole in the pipe
to allow me to put a piece of metal in the pipe to break up the fat.

Any other ideas, apart from replacing the pipe.

Thanks

If all else fails, use heat. A hose pipe connected to the hot tap
used in the same way as rodding may shift the offending fat.


If it is outside, then tipping in a large bucket of hot water from as
high as possible will often clear the blockage, as the hot water goes
to the bottom and helps to soften the fat, and also the water pressure
pushes the blockage at the same time. Might need a few attempts.
Failing that leave it overnight to see if the caustic has worked.
Nice ideas but the Ubend is in the way hopefully the text drawing below
will make things clearer

Yes but as you tip the hot water in it goes to the bottom where it is
needed to melt the lard. Also it has a hydraulic effect on the blockage.
I have used this method several times with success.
