Why does my basement floor drain back up when it rains?
A floor drain that backs up when it rains is usually not a clog in the drain itself. It means the sewer line outside the house is full, and the water has nowhere to go but up through the lowest opening, which is your basement floor.
Heavy rain can push extra water into the main line through cracked joints, root intrusion at a clay joint or a failed sewer lateral. The line fills, and the floor drain shows it first.
Safe homeowner check: on a dry day, pour a bucket of water into the floor drain and see if it runs away normally. Keep stored items off the floor, and do not run the washer, showers or dishwasher during the storm.
Stop running water and call now if sewage is rising, the smell is strong, or every drain in the house is gurgling or backing up. That points to the main line, not one fixture.
A cable machine can clear roots or grease when a blockage is the cause. If the line keeps filling in wet weather, a camera inspection is the next step, because it shows whether the pipe is cracked, bellied or breached. Hydro jetting washes the pipe wall once the cause is known. Cost depends on access, how much has to be opened up, the materials involved and any permit requirement.

Pay attention to how fast the drain responds, because it tells you how serious the cause is. If the water rises within minutes of a downpour starting and drops soon after it ends, the line is being overloaded by water entering through cracks or joints. If it stays up for hours after the rain stops, something is also holding water in the pipe, such as a belly or a root mass. Older homes often have clay or cast iron lines with many joints and sometimes a downspout or foundation drain connected to the sewer, which makes wet-weather backups more likely. Newer homes with plastic pipe usually have fewer joints, so a backup there points more strongly to a blockage or a municipal main running full. Tell the plumber when the backups began, how heavy the rain was, and whether any gutters or sump discharge are tied into the house drains. Once the cause is fixed, the floor drain should stay quiet through storms.
What causes scale build-up inside old cast iron drain pipes?
Scale in cast iron is rust and mineral deposit growing on the inside wall of the pipe. Cast iron corrodes from the inside over decades. The rust forms rough lumps, called tubercles, and minerals carried in the water settle on them. Grease, soap residue and paper then catch on that rough surface and the bore gets smaller.
The homeowner sees it as drains that slow down over time, often more than one fixture at once, and gurgling when a tub or washer empties. The pipe can look fine from outside while the opening inside has shrunk to a fraction of its size.
A cable machine will punch a hole through the scale, but the water often keeps running through a narrow channel and the build-up returns. Hydro jetting strips the wall back much more completely. Before either one, a camera inspection is worth having on old iron. It shows how much scale there is and whether the pipe wall is thin, cracked or flaking, because a line that is weak can fail once the scale holding it together is cleaned off.
What the job costs depends on access, the pipe material involved, how much has to be opened up or removed, and any permit or code requirement. If sewage is backing up into the house, stop running water and call. Expert Plumbers Co is a referral service.

A point many people miss is that cleaning scale is not always the end of the story. Once the wall is stripped back, the bare iron can start rusting again, so the line may need cleaning more than once over the years if the pipe is not replaced. Another sign it is getting worse is rusty or dark water standing in a drain that used to run clear, or small flakes of rust in a trap. In homes built before plastic pipe became common, a camera also shows whether the line is worth keeping or is near the end of its life. Pipes that are thin or cracked may need a section replaced, and that can be done in stages rather than all at once. When you call, mention the age of the house and any previous repairs to the drains, since patches in old iron often use different materials.
We run a cafe and the kitchen line keeps blocking. Is that the same job as a house drain?
Not quite. A kitchen line that blocks again and again is usually a grease problem, and that is a different job from a house drain.
A cafe pushes far more fat, oil and food solids down the pipe than a home does. The grease cools, sticks to the pipe wall and builds layer on layer. The opening shrinks each week. That is why the blockage returns on a short cycle.
A grease interceptor, also called a grease trap, sits between the kitchen and the main line. It catches fat before it travels downstream. It only works while it has room. Once it is overfull it stops holding grease and passes it straight into the line. So it needs servicing on a schedule, not just when something goes wrong. Many jurisdictions require an interceptor and expect records of each servicing. That is a code matter, so check with your local authority.
A cable machine punches a channel through the grease and leaves the coating on the wall. Water drains for a while, then the channel closes again. A commercial line usually needs hydro jetting, which uses high-pressure water to strip the wall clean. A camera inspection then checks the pipe underneath for cracks, roots or a sag that holds water.
One slow sink is a branch problem. Every fixture backing up points to the main line.
A blocked line in a food business is a shutdown risk, so timing matters. If water is rising near the prep area, stop using the sinks and call.
What the job involves depends on access to the line, how much has to be opened up, the condition of the pipe and any permit requirement. Expert Plumbers Co is a referral service. Call (380) 262-9173 and we will refer your cafe to an independent local plumber in Birmingham, MI.
Keep a servicing record and a routine. Write down the date each interceptor is serviced and by whom. Authorities that require interceptors usually ask to see those records.
Train kitchen staff on what goes down the drain. Scrape plates and pans into the trash first, fit fine mesh strainers in every sink, and never pour fryer oil down any drain, even with hot water, because it cools further down the line and sets. Hot water and soap only move grease along the pipe. They do not remove it.
Learn the warning signs of a full interceptor: slow draining at the sinks nearest it, a sour or rancid smell, or grease showing in the outlet chamber.
Set the jetting interval after a camera inspection shows how fast the coating builds, so cleaning happens before a lunch rush is lost to a backup. Mention any recent menu change toward fried or fatty food when you call.
The laundry sink in my basement fills up when someone uses the drains upstairs. Why?
A basement laundry sink is often one of the lowest open drains in the house. When it fills with water from upstairs, that water is coming back up the main drain because the line below is blocked or too slow to carry it away.
Everything upstairs drains down through a vertical stack and into the main line that leaves the house. If that main line is partly blocked by roots at a clay joint, a bellied section holding water, or grease and wipes that have built up, the flow stops short and rises to the lowest point. That is the basement.
Check whether the floor drain, a basement toilet or a shower shows the same thing. If the laundry sink fills when you flush an upstairs toilet or run the washing machine, the main drain is the likely cause. If it only happens with the dishwasher or one bathroom, the blockage may be on a branch line instead.
Safe checks you can do: stop running water in the house for an hour and see whether the level drops. Find the cleanout, a capped pipe near the floor or outside wall, and note where it is for the plumber, but do not open it while the line is full. Do not run the washing machine or take showers to test it, and do not use chemical cleaner.
Stop all water use and call now if the water in the sink is dirty or smells, if it is rising, or if it spills over the rim. Sewage in a basement is a health hazard, so keep people and pets away and do not touch it without gloves.
A cable machine can clear a soft blockage in the main line from the cleanout. If it returns, or if the cable stops at the same spot, a camera inspection shows whether roots, a bellied pipe or a failed sewer lateral is behind it. Hydro jetting clears grease and roots more thoroughly than a cable, and a damaged line may need a repair or replacement section.
Cost depends on access to the cleanout, how far the blockage sits, whether roots or a collapsed pipe are involved, and how much has to be dug or opened.

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.
