Troubleshooting common toilet problems
Not a single fixture or appliance in our homes is more crucial to our  sanity than the lowly toilet. We expect our commodes to work every  time, and we cringe with foul distaste when one fails in its humble  mission. Yet a malfunctioning toilet must be fixed post-haste! If the  kitchen sink is clogged, that can wait. Not so the potty. And it's all  so distasteful: it's damp, perhaps a bit moldy inside, fouled by  unspeakable germs and vile gunk no human should touch. The thought of  calling a plumber, however, conjures visions of an exorbitant and  illegible bill for emergency service.
Here are three secrets,  revealed: First, you probably can repair that mis-behaving toilet  yourself. Second, toilets aren't nearly as complicated as you fear. And  last, except in the case of a truly disturbing overflow of the bowl,  your toilet is much cleaner than you might expect. On the other hand,  your fears of a pricey service call are well-founded. It's not at all  unusual to pay almost $200 for a plumber's visit. For about $50 more  than that, you could have a new toilet installed. It's worth your time,  worth overcoming your reluctance, to at least give it a look.
Anatomy of the common toilet (U.S. design, residential):

Starting  at the top: 
THE TANK. Although there are endless variations in shape  and size, every commode has a water reservoir, usually a separate tank  that holds ordinary tap-water used for flushing. A pipe emerges from the  wall or floor nearby; most often you'll find a shut-off valve (with a  small handle of some sort), which leads fresh water through a supply  tube up to the tank. [Some tanks are cast as a unit with the bowl. This  is a designer trick which makes repairs and replacement deliberately  more expensive.]
Below the tank: 
THE BOWL. This part of the  commode holds a second reservoir of water, necessary for effective  flushing and for sealing off the sewer line from the air in your home.  Most of us believe the toilet bowl to be hopelessly contaminated with  exotic microbes. Unless you never clean it, that simply isn't true. Your  kitchen sink almost certainly harbors more hazardous germs, especially  if you have a garbage disposal.
The bowl covers the critical 
 DRAIN. This is an two- to four-inch opening in the floor, leading  directly to your main sewer or septic line. A clogged drain line doesn't  even involve the toilet fixture itself; the problem's in the pipes. If  your trouble lies in the drain line beneath the floor, that's the right  time to call a plumber.
Things that can go wrong, and can be fixed:
Your  shut-off valve can become clogged over time. If the tank seems to take  an eternity to fill, the valve may need replacement. There's a second  shut-off inside the tank, too: the one that sometimes doesn't stop  running after you flush. For most toilets, that part costs less than $20  to replace. A typical brand of tank-filler is "Fluid-Master," sold in  every hardware store. If you can shut-down either your water main or the  valve with the handle below the tank, then you can do this job  yourself. Cures most slow-fill or won't-stop-running issues.
Sometimes  the "flapper" fails to function. In this case, water continually seeps  or gurgles into the bowl (possibly wasting hundreds of gallons a week).  Jiggling the handle is a common short-term solution. However, while the  flapper's design varies from brand to brand, most home-owners can handle  replacing that part themselves. Turn off the toilet's water supply for  this chore, too.
The most humbling and distasteful problems come  when the 
drain becomes clogged. If your handy plunger fails to clear the  clog, go ahead and call a plumber. You could try "snaking" the drain  yourself, but that's not a job for the faint-of-heart. Clogged drains  can usually be blamed on some variation of "too much toilet paper."  Prevention, and education of blissfully ignorant family members, is the  only way to avoid recurrence.
The critical point: 
try not to be  afraid. It's only a toilet. You don't have to be a rocket scientist to  show the commode who's boss.
