The toilet backs up and your mind jumps to the obvious fix
You flush, the water rises instead of draining, and your first instinct is to grab a plunger. That instinct is fine. But before you touch anything, walk through your house and check every drain. The bathtub, the other toilet, the kitchen sink, the washing machine standpipe, the floor drain if you have one in the basement or garage. This takes five minutes and it tells you something a single clogged toilet never can.
If only one fixture is backed up, you're probably dealing with something local to that fixture or the branch line behind it. If two or more fixtures in different parts of the house are acting up at the same time, especially if the lowest drain in the house is the worst one, you're looking at a problem in the main line, the pipe that carries everything out to the city sewer or your septic tank. That distinction changes everything about what happens next.
Why this matters more in Nixa than it would somewhere flatter and older
Nixa sits on rolling Ozark terrain, and a lot of the housing stock here was built from the 1990s onward as the town grew fast. That means a mix of plumbing ages and materials: newer PVC in subdivisions off Mt. Vernon and Gregg Road, older clay or cast iron closer to the original downtown core, and plenty of homes with long lateral lines running through yards with heavy clay soil. That clay soil holds water and shifts with the seasons, which puts steady pressure on buried pipe joints over the years.
Winter freeze and thaw cycles here aren't as brutal as farther north, but Nixa still gets enough hard freezes to move soil and occasionally crack aging pipe. Spring brings heavy rain off the Ozark plateau, and saturated ground raises the water table enough to back up main lines that are already struggling. A multi-fixture backup that shows up after a few days of soaking rain is telling you something specific about where the trouble is.

What you can actually check yourself
Start with the cleanout, the capped pipe sticking up near your foundation or out in the yard, usually on the side closest to the street. If you can find it and safely remove the cap, take a look or listen. Gurgling, slow movement, or water sitting at the top of the cleanout confirms a main line issue rather than something isolated to one fixture.
Check your yard too. A soggy patch of grass that stays wet when everything around it is dry, a sewer smell outside near the lateral line, or grass that's suspiciously greener in one strip can point to a leak or break underground. None of this requires tools beyond your eyes and maybe a flashlight. Write down what you notice and when, because that timeline helps whoever ends up working on it.
What's reasonable to try before calling someone
If it's just one fixture, a plunger or a hand auger from the hardware store is a fair first attempt. Standing water in a single sink or tub that slowly drains is usually a local clog you can manage yourself. Avoid chemical drain cleaners if you think the problem might be further down the line. They don't do much for a real blockage and they make the job worse and more hazardous for anyone who has to open that pipe later.
If multiple fixtures are backing up, or if water is coming up through a floor drain, stop trying to fix it with household tools. That's not a clog you plunge your way out of. Pouring more water down a drain to test it, running the dishwasher, doing laundry: all of that just adds more volume to a system that's already struggling to move water, and in older homes with a septic tank it can push the problem into the yard or even back into the house.
When it stops being a homeowner job
Once you've confirmed it's a main line problem, or you can't find a cleanout, or the backup keeps coming back after you've cleared it, you're past the point of a wrench and a bucket. Main line clogs and breaks usually need a camera inspection to actually see what's going on, root intrusion, a bellied section of pipe, a collapsed joint, and then equipment to clear or repair it. That's not a weekend project, and in a lot of Nixa's older sections with mature trees along the street, root intrusion into clay pipe is common enough that it's worth assuming until proven otherwise.
The fixture count you did at the start is the single most useful piece of information you can hand to whoever looks at this next. It narrows the search before anyone opens a pipe.
