About three weeks ago my, water heater died and we had it replaced.
When they did so, they had to add a tank on the top of the water
heater that was not their before (http://www.lowes.com/lowes/lkn?
action=productDetail&productId=160680-48324-LET-2&lpage=none not the
exact one but its basically the same thing). Its now required in my
city due to some water meter changes the city made. Anyway, as soon as
the guys (yes I hired someone) finished the toilet started to hiss. I
don't think that an abnormal amount of water is going from the tank to
the bowl so its not a constant refilling issue. If I close the shut
off value the noise stops, and when I open the value the noise starts
again. If I leave the valve open for a few days the noise gets louder
(it gets to the point of annoying and then I close the valve). Here is
another strange point. I was changing a hot water shut off value in
the kitchen, and I noticed when I close the hot water valve coming
from the water heater the noise in the toilet jumped.

Anyway, whats going on to make the hissing noise?

Should I just get one of those replacement kits at Home Depot or Lowes
and see what happens (noticed they are less than $15).

Is the water level in the tank overflowing?

No really overflowing. I have noticed that there is more water in the
tank than there should be (water level is above the hard water
stains).

Or is the tank refilling
without anyone flushing it?

I don't think the tank is refilling itself. I did the dye test a few
weeks ago and after 20 minutes had a very tiny bit of dyed water in
the bowl.

IMHO:

Maybe the tank is draining, per your test, and the fill valve is now
throttled to maintain the level. Meaning a little is leaking by the
flapper, and then some water is being entered into the tank and that
is making the sound.

Since I don't like wasting resources, since it usually comes as
wasting money for me, I would check the flapper. It could just need a
wiping down with a clean rag. If not have someone who knows what they
are doing to help diagnose/fix the problem.

Just a guess...
