One of the 3 toilets in my house doesn't flush completely about 50%
of the
time. Usually, when the toilet doesn't flush completely, any solids
will
still be removed but the water just kinds of swirls around without
completely flushing. If I reflush (when tank refills) the second
time will
almost always work OK. Sometimes the first flush will work just
fine.

The toilet has been in the house since it was built in the 70s. The
toilet
is not the newer type that uses less water.

I have tried a plunger, but I don't think the line is blocked.
Shower and
sink in the same bathroom work OK.

I have had this problem on and off for years but I've just lived with
it.
Lately, it seems to be getting a little worse.



"hallerb" in this newsgroup gave this suggestion to me and it works
beautifully. Try it, I think you'll be surprised at how well your
toilet flushes after doing this. It worked wonders on mine.

Using Muriatic Acid

First IDEALLY the toilet bowl will have NO water in it! So plunge or
sponge out the water in the bottom of the bowl.

Tank water doesnt matter.

Wear safety glasses, have window on or exhaust fan on.

Use funnel pour about a cup down the dip tube, and perhaps a cup in
the bowl. Work pretty fast.

Like take a deep breathe, hold it, pour in acid, leave room wear
rubber gloves.

Shut door wait 15 minutes, flush repeatedly like 5 to 10 times.

Actually despite the warnings muriatic acid is pretty mild, you DONt
want it in your eyes or splashed on floor or belongings but I touched
some just to see, my finger didnt rot off

dO IT TWICE IF NECESSARY, you will likely see lots of brown gunk from
the bowl rim in the bowl.
