Mom's terlet refills every hour or so, and I replaced the flapper. It
didn't fix the problem.
She has a thirty year-old toilet and I noticed that the "drain hole" in
the tank is sloping (i.e., the "rim" is lower on the side farther from
the fill tube and considerably higher on the side near the tube).
Is this unevenness a sign of erosion, or do those holes--sorry I don't
know their techical name--come on some models at a sloping angle?
Finally, if a sloping drain hole ISN'T normal under any circumstances,
is there a way to repair it without replacing the toilet? (As readers
of some other posts on this group may be aware, Mom's up to her kazoots
in other home maintenance expenses this season.)
BULLSHIT! m_Ransley strikes again.
The "drain hole" not being level is absolutely normal. It's made that way
so the flush valve (flapper), which is attached to and pivoted at the fill
tube, will seat properly. If the tank is refilling periodically it normally
means water is leaking out somehow or the fill valve is defective or
misadjusted. Your assignment, if you choose to accept it, is to determine
"what be happenin".
If the tank water level is slowly going down and there is no water on the
floor, determine if the leak is at the flush valve (flapper). The common
way is to add some food coloring (I prefer purple but that's just me) to the
tank water and watch to see if it appears in the bowl. If it does, replace
the flapper with a new, good one. The holy H or Lowe's has 'em -
Fluidmaster is the common brand and the red ones seem to be better than the
black ones (my experience). While you're at it, inspect & clean the valve
seat (the slanted thing you referenced earlier). If it is corroded it will
have to be replaced. If it's need cleaning, clean it. It must be free of
all debris and provide a smooth mating surface with that new flapper.
If no colored water shows up in the bowl, you may want to inspect the ball
float. If it leaks, water will enter it, over time, and it will no longer
float as high. As it sinks, it operates the fill valve, adding water to the
tank. This is not a very common problem.
Finally, notice the water level when the tank is full and the fill valve has
shut off. If it is too high, water may be spilling over into the overflow
tube. That's the vertical tube, about 3/4" in diameter, usually next to the
fill valve assembly. The tank water level should be about 1/2" below the
top of the tube. If it's too high you can adjust the fill valve. Sometimes
this means bending the rod that the float is attached to.
Hope your Mom's "kazoots" are better.
It might be possible to repair it with a replacement
seat. You have to drain the tank and dry the existing
seat, then the replacement sticks down on it. I don't
know how much leveling that will do, but I did it to
mine that kept dripping, and it has been working fine
for years now.
