The Sewer Problems Forsyth County Homeowners Actually Run Into

A sewer line problem in Cumming usually has one of four causes, and which one you have depends mostly on when your house was built and what is growing in your yard. Forsyth County has a specific mix of soil, trees and housing stock that produces the same handful of failures over and over. Here they are, in the order we find them.

1. Roots, which cause more failures than everything else combined

Forsyth County is full of mature hardwoods and pines, and that is one of the nicer things about living here. It is also the main reason sewer lines fail.

Roots are looking for water and nutrients. A sewer line is full of both. They do not need a big opening to get in, and they do not need to break the pipe first. A hairline crack, a slightly loose joint or a worn gasket is plenty. Once a root tip finds that gap it grows into the line and then keeps growing, spreading into a mass that catches everything moving past it. Paper, grease, solids. The blockage builds slowly, which is why the symptoms creep up on you over months rather than appearing overnight.

Willow, maple and silver maple are the worst offenders. Pines are less aggressive but they are everywhere here and they are persistent.

How it is actually fixed. Cutting roots with a mechanical auger clears the line today and the roots come back, usually within a year or two, because the opening is still there. Hydro jetting does a far more thorough job of scouring the pipe wall clean. But the permanent answer is closing the entry point, which means repairing or lining that section of pipe. Anyone who tells you a single auger pass has permanently solved a root problem is selling you the same job again next year.

2. Bellies, which are the red clay problem

A belly is a low spot in a sewer line where the pipe has sagged. Instead of running continuously downhill, the line dips, and waste sits in the dip rather than flowing through.

This is very much a Forsyth County problem, because our red clay expands when it is wet and shrinks when it dries. Do that for twenty years and the soil supporting a pipe moves. Add poor compaction under the original trench, which was common on fast built subdivisions, and the pipe settles into a low point.

A belly does not fully block anything at first. It just slows things down and collects solids, so it looks like a recurring clog. People snake it, it works for a while, and then it happens again in the same spot. If you have cleared the same blockage three times, you probably do not have a clog. You have a belly.

How it is actually fixed. There is no way to clean a belly out permanently, because the low spot is still low after you clean it. The section has to be dug up and relaid at proper fall, with the trench compacted correctly this time. It is honest work and there is no shortcut, so be cautious with anyone who claims they can jet a belly away.

If you have paid to clear the same blockage three times in two years, stop paying to clear it. Pay once to look at it.

3. Old pipe material

What your line is made of tells you a lot about what will go wrong with it.

• Clay tile was used into roughly the 1970s and shows up on older Cumming properties. It comes in short sections with a joint every few feet, and those joints are an open invitation to roots. It also cracks
• Cast iron was common through the mid 1980s. It is strong but it corrodes from the inside. As the wall roughens, the inner diameter narrows and waste catches on it
• Orangeburg, a tar and wood fiber pipe used in some mid century construction, deforms and collapses with age. It is not common here but we do still find it
• PVC, standard from roughly the mid 1980s on, is the good news. It does not corrode and joints are sealed. PVC lines mostly fail from crushing, bellies or roots at a damaged spot rather than from the material aging

So a 1978 house in Cumming with slow drains and mature trees has a very different likely diagnosis from a 2004 house with the same symptom.

4. What people put down the drain

This is the avoidable one.

Flushable wipes are not flushable. They do not break down. They catch on any rough spot or root intrusion and build a mat that stops the line completely. Grease is the other one. It goes down warm and liquid and cools into a solid coating on the pipe wall, narrowing the line a little more with every pan. Coffee grounds, cat litter and paper towels all belong in the trash too.

If you are on septic rather than a sewer connection, all of this lands in your tank and speeds up how fast it fills, which means more frequent pumping.

How we work out which one you have

Guessing at a sewer problem is expensive, because every wrong guess is a trench. So we look first.

A sewer camera inspection puts a camera down the line and shows the actual condition of the pipe. It tells us the material, where the problem is, how far from the house it sits, whether it is roots or a belly or a collapse, and how much of the line is worth saving. We can locate the trouble spot from the surface so that if digging is needed, we dig in one place rather than hunting.

That inspection is the cheapest step in the whole process and it is the one that prevents the expensive mistakes. It is also what we recommend before buying any older home in the county, alongside a septic check.

Warning signs worth acting on

• More than one fixture draining slowly, especially the lowest ones in the house
• Gurgling from a toilet when a tub or washing machine drains
• The same clog coming back in the same place
• Sewage smell in the yard along the line between the house and the street or tank
• One strip of lawn greener or more sunken than the ground around it
• Backups that get noticeably worse after heavy rain

That last one is worth a note. If your problem tracks rainfall, groundwater is getting into the line through a crack or a bad joint. That points at pipe condition rather than a blockage, and it will not respond to snaking.

What it is worth doing now

If your line is behaving, keep it that way. Do not plant trees over it. Keep wipes and grease out. If you have had roots before, get on a regular cleaning schedule rather than waiting for the next backup, because a scheduled visit costs far less than an emergency one.

Whoever you call, call somebody who does this for a living. The directory lists the septic and sewer companies in each market it covers, ordered by review count, with nobody paying for a position.
