The street sewer backed up into my house. What is a backwater valve?
Sewage came up through the basement floor drain, or a low toilet or tub gurgled and overflowed, during a storm or a heavy-use evening.
The usual cause is the municipal main in the street filling past capacity, called surcharging. With nowhere to go, the flow pushes back up the lateral and out of the lowest opening in the house.
A backwater valve, also called a check valve, is a fitting on the lateral or building drain with a flap that lets waste leave and shuts when flow reverses. It sits on the line ahead of the branches serving the lowest fixtures.
Fitting one is not a quick swap. It usually means opening the floor or digging to reach the pipe. What it involves depends on access, the depth of the line, the valve and materials, how much has to be opened up and restored, and whether a permit or code sign-off is required. Rules vary by area.
A valve does not fix roots at a clay joint or a bellied line holding water. It only stops reverse flow. A private line problem needs a camera inspection first, then a cable machine or hydro jetting depending on what the camera shows.
Street or private? Ask three things. Are the neighbors affected? Did it coincide with heavy rain? Is only the lowest opening backing up while upper fixtures drain normally? Yes to those points to the street main. Only your house, in dry weather, points to your own lateral.
Safe homeowner check: look at the neighbors and the forecast. Stop running water now: no flushing, washer or dishwasher. Keep people and pets out of contaminated water, and call.

After the cleanup, ask how the valve will be kept working. The flap and its hinge can be stopped by lint, grease and grit, and then it no longer seats fully. Most valves have an access cover so the flap can be looked at and cleaned, and that should be done on a routine, not only after a storm. Learn where the cover is and keep boxes and floor coverings off it.
One point catches people out. With the valve closed during a storm, your own household water has nowhere to go either. Showers, sinks and the washer will fill the line behind the flap, so keep water use low until the street main drops.
After any backup, the floor drain and the area around it need to be cleaned and disinfected. Porous materials that soaked up sewage, such as carpet pad and cardboard, usually have to be removed rather than dried.
Water or sewage is seeping out around the cleanout cap in my yard. What does that mean?
If liquid is seeping up around the cleanout cap, the sewer line is full to ground level at that point. The cleanout is a capped pipe that gives a plumber direct access to the main line, and it is often the lowest open point on the system. When a blockage sits downstream, waste water rises until it finds the weakest spot, and that is frequently the cap.
Less often the cap itself is the problem: a cracked cap or worn threads can weep a little after heavy use. The difference is the smell and the timing. A damp ring with no odor that dries out is one thing. Grey or dark water with a sewage smell that returns every time the house uses water points to a blocked or partly collapsed line.
Look at the rest of the house. If one fixture is slow, the trouble may be local. If several drains are slow, toilets gurgle, or a floor drain or shower fills when the washer runs, the main line is the likely culprit.
Safe checks you can do:
Keep children and pets away from the wet area. Hold off on laundry, dishwasher cycles and long showers. Do not unscrew the cap. A line under pressure can spray sewage when the cap comes off, and that is a health risk.
Stop running water and call now if sewage is reaching the yard in a steady flow, if it is entering the house, or if the seep keeps growing while you are using as little water as possible.
On the repair side, a cable machine is often enough for a soft blockage such as paper or grease. Roots, heavy grease build-up or scale usually call for hydro jetting or a cutting head. A camera inspection afterwards shows whether the pipe is cracked, bellied or offset at a joint, which decides whether cleaning will hold or whether a repair is needed. Cost depends on how easy the cleanout is to reach, how far the blockage sits from it, how much needs to be dug or removed if a repair follows, and permit requirements under local code.
If the line has to be opened for repair, the local building department may need to be involved. To be connected with an independent local plumber in Hernando, MS, call Expert Plumbers Co on (380) 262-9173.
There is a soggy strip, a sinkhole or an unusually green line of grass over where my sewer runs. Is that a broken sewer line?
It can be. A wet strip, a dip in the lawn or a stripe of grass that is greener than the rest, all following the path of the sewer, is a classic sign that the pipe is leaking into the soil. Waste water carries nutrients, so the grass above it grows lush while the ground underneath stays soggy.
A sinkhole is more serious. If soil is washing into a cracked or separated pipe, it leaves a void that grows over time. The surface may look fine until the roof of that void gives way. Keep people, pets and vehicles off the area and do not fill it yourself with a quick load of dirt, because the hole will usually return.
Other things can look similar, so check before assuming. A leaking irrigation line, a broken water supply pipe or a downspout discharging at that spot can all soak a strip of lawn. A simple test: shut off every tap and appliance, then look at your water meter. If it keeps moving, the leak is likely on the supply side, not the sewer. If the meter is still, and you also notice slow drains, gurgling, a sewage smell outdoors or backups, the sewer is the stronger suspect.
Safe checks you can do:
Note where the wet or green strip runs and whether it lines up with the cleanout or the path to the street. Reduce water use until the line is looked at.
Stop running water and call now if sewage is surfacing, a hole is opening, or drains inside the house are backing up.
Cleaning alone does not fix a broken pipe. A camera inspection is how a plumber finds the break, shows how far the damage runs and tells whether the pipe is cracked, offset at a joint or collapsed. Repair can then be a spot repair, a liner through the existing pipe, or replacement of a section. Cost is driven by depth, length of pipe affected, what sits on top of it such as a driveway, trees or a patio, how much has to be excavated, the pipe material and permits under local code.

The house has old galvanized steel drain lines. Why do they keep clogging, and what can cleaning fix?
Galvanized steel was used for drains in older houses, and it ages badly. The zinc coating wears off, the steel underneath rusts, and the inside wall turns rough and flaky. Rust scale builds up in layers, so the pipe gets narrower every year. Hair, soap and grease catch on that rough surface much more easily than on smooth plastic.
That is why you may see slow drains that clear for a few weeks and then slow down again. Threaded joints and fittings also form ledges where debris collects, and horizontal runs with little fall hold water and silt.
What cleaning can do: a cable machine can open a clog and scrape some loose scale off the wall. Hydro jetting can strip more of the buildup and restore much of the bore, as long as the pipe is still sound. A camera look first shows how thick the scale is and whether the steel is thinning.
What cleaning cannot do: it cannot make a worn pipe new. Rust scale can be holding a weak spot together, and aggressive cleaning of a pipe that is corroded through can open a leak or let a section collapse. A pipe that has pinholes, rusted fittings or wet stains at the joints is near the end of its life, and clearing it again and again is a short-term answer.
Do not use chemical drain cleaners on old steel. They sit in low spots and speed up the damage, and they are a hazard for whoever opens the line afterward.
A safe check: look in the basement or crawlspace for rust streaks, flaking, drips or damp spots on the drain pipes. If you see them, or if every fixture on the same stack runs slowly, tell the plumber what you found.
If a section is too far gone, the usual choices are to replace the worn runs with modern pipe or, for some lines, to line them. Cost depends on how much pipe is involved, how easy it is to reach, whether walls or floors must be opened, the materials, and local permit rules.

My child flushed a toy, or something solid went down the toilet. What should I do, and what should I not do?
Stop first. Do not flush again, even if the water looks like it is going down. Each flush pushes the object further along, and it can lodge in the toilet's trap or in the drain behind it. Tell everyone in the house not to use that toilet.
If the toilet still drains but the bowl is high, leave it. If it is rising toward the rim, lift the tank lid and push the flapper down, or turn the shutoff valve behind the toilet clockwise to stop more water entering.
What is safe to try: if you can see the object near the bowl opening and it is not breakable, put on gloves and pick it up. Use a wet vac or a closet auger only if you are comfortable with it, because an auger can also shove a hard toy deeper. Be gentle with a plunger. A plunger can free a soft item, such as paper or cloth, but it often wedges a solid piece tighter.
What not to do: do not use chemical drain cleaners, which do nothing to a solid object and make the water dangerous to handle. Do not keep plunging hard, and do not push a coat hanger down the drain, which can scratch the porcelain or drive the object into the pipe wall.
If the object has already gone and the toilet seems normal, watch for slow drains, gurgling or other fixtures backing up over the next few days. A small toy can catch in a bend and collect paper behind it. If the toilet becomes slow, or the same one keeps clogging, the object is probably still in the line.
In that case the plumber may pull the toilet off its seat to retrieve it from underneath, which is often cleaner than cabling into a pipe. If the item is in the drain behind the toilet, a camera can find it and the plumber can retrieve it or push it clear. Cost depends on where it lodged, whether the toilet must be removed, and how much access is needed.
