Using One Shot drain clearer in sinks

Our kitchen sink drain is blocked and only draining slowly. I have a
bottle of One Shot acid - is it Ok to use on plastic pipes and what's
the best procedure?
Instructions say remove as much water as possible first and then add
water once you have put in 125ml acid - obviously I can get rid of the
all the water in the trap but I was taught never to add water to acid...
Is it best to slowly add to the water in the trap and then wait and
then flush some cold water from the tap?

for situations like this as it coats all the gunk in the pipe. I've
cleared a slow draining shower - took 3 goes but now the water just runs
away rather than filling the tray to 3" deep.
To answer your question, we'd need to know the make of the cleaner - or
its ingredients.
Your teaching only applies to adding water to concentrated acids where
the mixing releases a lot of heat - notable conc. sulphuric acid. Conc.
HCl is no problem mixing with water. Also applies to sodium hydroxide
crystals.

out the living scunge and to a degree attacks grease - the problem is it
doesn't get to the upper parts of the pipe, which is where the foaming
stuff comes in handy. I've only ever used acid on limescale.

One Shot is usually added to water in a WC, technically the wrong way
around, but you can't do anything else. As you say it will badly damage
SS sinks, chrome wastes and anything else.

Shot" claims to be 94% sulphuric acid, if it really is that strong
then, yes, you should add acid to water. However, I'm amazed that
they're allowed to sell acid that strong, if it really is.

In article <2016040219005191240-nospam@nospamcom>,
On a trip browsing around Lidl (an excuse for a cycle ride), I picked
up one of those "that might be useful one day" purchases, which is a
pipe cleaning kit you connect to a pressure washer outlet, like a smaller
version of the ones Thames Water used up a blocked sewer.
About 2 weeks later, the kitchen sink blocked enough that the dishwasher
pump-out backed up into the sink and then drained away slowly.
Took the U-trap off, but could instantly see the problem was the exit
pipework was gundged up, with only about a 1/2" holw left down the middle
for the water to flow away. Fetched the pipe cleaner from the garage,
connected up the pressure washer, and it worked fantastically. Pushed
the cleaning head right through until the pipe opened out into the 4"
waste pipe from upstairs. The backwards-facing jets chisseled the grime
off the pipe, leaving the small part I could see (and I assume the rest
too) looking like nice new shiny plastic.
Cleaning head won't go around a U-trap, but it managed the other bends.
I did have a little difficulty pulling it back out of the 4" pipe back
into the 40mm branch, because a heatshrink sleave on the end was catching
on an edge in the pipework, but it eventually released.

If it *is* downstream of the trap, you may be able to get some sort of
flexible device down the pipe to clear it if you first remove the trap
to get access to the pipe.
I would regard powerful chemicals as very much of a last resort.

I agree that this is a horrific story, and probably reason enough never
to use that product. All credit to the mother for doing exactly the
right thing and flushing liberally with water.
My understanding is that PVC, polyethylene, and polypropylene (as used
in normal 1 1/4 or 1 1/2 inch waste pipes) are resistant to concentrated
sulphuric acid, but ABS (as used in some 110 mm pipes) is not.
I do wonder, in the quoted case, whether the acid was released because
it dissolved a "seal" made from limescale, or perhaps the pipes were
already degraded in some other way.
If that 91% concentration is high enough to show the classic overheating
reaction when water is added to concentrated sulphuric acid, I am quite
surprised to see it so readily available on sale.

Its a very strong reducing agent IIRC. So any plastic with oxygen
molecules in it is prone to attack

looks like the PVC/polythene classes are OK, but acetal which is a sort
of nylon, is not.

Indeed. On the B&Q web page
http://www.diy.com/departments/one-shot-drain-cleaner-bottle/254799_BQ.prd
they don't actually say it can be used on waste pipes. And given that
they claim it can dissolve "grease , rags, soap, paper towels in minutes"
it's rather surprising that the bottle itself, or the web page isn't
plasterd with hazard warnings; maybe other websites are more
informative. It's the "rags" bit there that seems a bit scary.
As most people will only discover they have a blocked waste pipe
as a result of the pipe filling with water maybe the product
is sufficiently diluted during those minutes when its dissolving
the grease , rags, soap, paper towels so as to not to effect
the plastic, or any joints.

I don't think we can entirely trust the DM to report things accurately.
We simply don't know what happened. The DM reported "But the liquid
was so strong that it melted the pipes, floor and ceiling".
How much did he use? Did he follow the instructions & flush?
The manufacturer clearly states that it will not harm plastic pipes.

the *acidity* of Sulphuric Acid that makes it so corrosive.
Concentrated Nitric Acid and Hydrochloric Acid don't even affect the
skin all that much, I remember simply washing spills off our hands at

yellow marks. Concentrated Sulphuric on the skin is another matter
altogether.

surprising that they say it can attack almost anything.
A better strategy is to look at data from suppliers of plastics, and
many common plastics are reasonably resistant to sulphuric acid up to
"battery acid" strength. When you get stronger than this, or up to oleum
(fuming sulphuric acid) you need to be more careful.
There's also a big difference between leaving it in contact with
plastics for long periods, maybe years, and letting it soak in a trap
for half an hour before flushing it away with a large excess of water.

Lovely stuff oleum. A saturated solution of sulphur trioxide in

pure sulphuric acid. (SO3 in H2SO4).
Very hydrophilic, and an extremely powerful oxidizing agent.
