| I have a recurring clog in my main sewer line. A local plumber mentioned hydro jetting, but I’ve always used a drain snake in the past. What is the main difference, and which one is safer for my pipes?

| Drain Snaking (Cabling):
- How it works: A mechanical cable with a spinning blade punctures through the blockage to restore flow.
- Best for: Minor clogs, localized blockages (like a sink or toilet clog), or opening a single path through tree roots.
- Limitation: It clears a path through the clog, but leaves grease, sludge, and debris built up on the pipe walls, meaning clogs can quickly return.
Hydro Jetting:
- How it works: Uses high-pressure water streams (typically 3,000 to 4,000 PSI) to thoroughly scour the inner walls of the pipe.
- Best for: Heavy grease buildup, recurring sewer line blockages, stubborn tree roots, and restoring pipes back to nearly original diameter.
- Safety note: A video camera inspection is always recommended before hydro jetting to ensure the pipes are structurally sound and not crushed or severely cracked clay/cast iron.

| The camera inspection showed the pipe is old clay tile, in decent shape but with a couple of joint offsets where roots have gotten in. Given that, is hydro jetting still safe, or does clay tile need a gentler approach? Also, roughly how often will I need to repeat it if this keeps happening?

| Clay tile is actually one of the more jetting-tolerant materials when it's structurally sound — the pipe walls themselves are hard and don't erode easily under water pressure. The bigger concern with clay isn't the jetting itself, it's the joints, which is exactly what your camera found.
On safety for your situation:
- A competent tech will use a lower-pressure, higher-flow nozzle near joint offsets rather than a full-aggression root-cutting nozzle, to clear the roots without further disturbing the joint.
- Since the offsets are minor (not full separations or bellies), jetting is generally considered safe here — but it's worth asking your plumber to go slow and monitor the camera feed in real time as they pass those specific joints.
On repeat frequency:
Joint offsets are entry points that won't close on their own, so roots will likely find their way back in periodically. Realistically:
- Expect to jet that line roughly every 1–2 years as a maintenance rhythm, rather than waiting for another full backup.
- If it becomes a recurring nuisance (every year or more often), it's worth pricing out a trenchless spot repair or CIPP lining at those specific joints — sealing them permanently is usually more cost-effective long-term than repeated emergency jetting once you're dealing with a chronic root-entry point rather than an occasional clog.

| How do I know if my sewer pipe needs repair after hydro jetting?
I've had my main sewer line cleaned with hydro jetting because of recurring clogs and tree roots. The water is flowing normally now, but I'm wondering how to tell if the underlying pipe still has a problem.
What signs indicate that a sewer pipe needs repair or replacement rather than just another cleaning?
If a camera inspection shows cracks, offset joints, or root intrusion, does that always mean the pipe needs to be replaced, or are there situations where regular hydro jetting is enough?

| How do I know if my sewer pipe needs repair after hydro jetting?
Hydro jetting can restore the flow of a sewer line, but it does not repair structural damage to the pipe. If the underlying problem is a cracked pipe, separated joint, severe offset, or collapsed section, the blockage may eventually return.
The best way to determine the condition of the line is a sewer camera inspection after cleaning. This allows the plumber to see whether roots are entering through joints, whether there are cracks, and whether the pipe has significant deformation or separation.
Not every root intrusion requires complete pipe replacement. If the pipe is structurally sound and roots are entering through a small number of joints, periodic cleaning may be a reasonable maintenance approach. A localized repair or trenchless lining may also be an option in some situations.
However, if the camera shows a collapsed section, major separation, severe cracking, or a significant belly that prevents proper drainage, cleaning alone will not solve the underlying problem.
The frequency of recurring clogs is another useful indicator. If a sewer line needs hydro jetting every few months, repeatedly paying for cleaning may become less practical than addressing the damaged section.
In short, hydro jetting restores the pipe's flow; camera inspection determines why the problem keeps occurring. If the same location repeatedly develops roots or blockages, it's worth discussing a permanent repair with a qualified plumber rather than relying on cleaning indefinitely.

| Should I get a sewer camera inspection after hydro jetting?
I recently had my main sewer line cleaned with hydro jetting because of recurring clogs and tree roots. The drains are flowing normally now, but I'm wondering whether I should have another camera inspection after the cleaning.
Can a camera inspection confirm that all the roots and debris have been removed? Can it also show whether the pipe joints or cracks were damaged further during cleaning?
Is a post-jetting camera inspection necessary every time, or is it mainly recommended when the sewer line is old or has known structural problems?

| Should I get a sewer camera inspection after hydro jetting?
A camera inspection after hydro jetting isn't necessarily required every time, but it can be very useful when the sewer line is old, has recurring problems, or has known root intrusion or damaged joints.
The main purpose of hydro jetting is to remove buildup, roots, grease and other debris from the inside of the pipe. A camera can then show the actual condition of the pipe once the blockage has been cleared.
This is particularly useful with older clay or cast-iron sewer lines. The inspection can identify remaining root intrusion, cracked or offset joints, corrosion, collapsed sections, or other structural problems that cleaning cannot repair.
A post-cleaning inspection can also establish a useful baseline. If the line needs maintenance again in the future, you can compare the new camera footage with the previous inspection and see how quickly the roots or buildup are returning.
For a relatively new and structurally sound sewer line with a simple blockage, a follow-up camera may not be necessary. But if the line has recurring clogs, tree roots, old clay tile, or known joint offsets, a camera inspection is a worthwhile additional diagnostic step.
The important point is that hydro jetting cleans the pipe; it does not repair structural defects. If the camera shows that roots are repeatedly entering through the same damaged joints, it may be more cost-effective to repair or line those sections rather than continuing with periodic cleaning. The site itself recommends camera inspection before hydro jetting when pipe condition is uncertain.

| Why does my basement drain smell even though it isn't clogged?
I have a floor drain in my basement that drains normally, but every so often I notice a strong sewer smell coming from it. There is no visible blockage and water drains quickly when I pour some into the drain.
Could the P-trap be dry, or could there be another problem with the vent or sewer line?
What should I check first?

| Why does my basement floor drain smell like sewer gas?
A dry P-trap is one of the most common reasons for sewer odor coming from a basement floor drain. The trap normally holds a small amount of water that acts as a barrier between the room and the sewer system. If the drain is rarely used, that water can evaporate and allow sewer gas into the basement.
The easiest first step is to pour several cups of water slowly into the floor drain. If the odor disappears afterward, a dry trap was likely the cause.
For a drain that isn't used frequently, periodically adding water can help prevent the trap from drying out. In some situations, a suitable trap primer or other approved method can be installed to keep the trap charged.
If the smell returns quickly despite having water in the trap, there may be another issue. Possible causes include a damaged trap, a venting problem, a leaking drain connection or a sewer-line problem.
It's also worth checking whether the drain has a proper trap at all. Older basement plumbing sometimes has improperly modified or abandoned drains.
Don't pour harsh chemicals down the drain simply to eliminate the odor. They won't solve a dry or damaged trap and can create a hazard for anyone working on the plumbing.
If the basement floor drain repeatedly loses its water even when it isn't evaporating quickly, that deserves further investigation. A plumber can determine whether the trap is damaged or whether there is a problem with the drainage or vent system.
In most cases, start with the simplest test: add water to the trap and monitor it. If the sewer smell disappears and doesn't return, maintaining the water seal may be all that's needed.

| Can hydro jetting damage an old sewer pipe?
I have an older sewer line that has recurring root intrusion and grease buildup. The plumber recommended hydro jetting, but I'm concerned that the high-pressure water could damage an old clay or cast-iron pipe.
How can I tell whether my sewer line is strong enough for hydro jetting? Should a camera inspection always be performed first?

| Can hydro jetting damage an old sewer pipe?
Hydro jetting can be very effective for removing grease, sludge and tree roots, but the condition of the sewer pipe should be evaluated before using high-pressure equipment.
The biggest concern isn't simply the age of the pipe. An old clay or cast-iron line can still be suitable for hydro jetting if it is structurally sound. However, a collapsed, severely cracked or badly separated pipe may be damaged further or may not be a good candidate for aggressive jetting. The existing discussion on this thread specifically recommends camera inspection when pipe condition is uncertain.
A good approach is:
Perform a sewer camera inspection.
Identify cracks, offset joints, root intrusion and collapsed sections.
Select the appropriate nozzle and pressure for the pipe condition.
Monitor the camera during difficult sections when appropriate.
Perform another inspection afterward if the line is old or has known defects.
The nozzle choice and technique matter as much as the pressure rating. A professional shouldn't automatically use the most aggressive root-cutting nozzle on a questionable section of old pipe.
If the camera shows a structurally sound pipe with roots entering through a few joints, hydro jetting may be a reasonable maintenance solution. If it shows major separation, collapse or severe deterioration, repairing or replacing the damaged section should be considered instead of repeatedly cleaning it.
One useful advantage of a post-jetting camera inspection is that it creates a baseline recording. If roots return later, you can compare the new footage with the previous inspection and determine whether the problem is progressing.
In short: hydro jetting isn't automatically unsafe for old pipes. The important question is whether the pipe is structurally sound and whether the equipment is used appropriately for its condition.

| Why does my sewer line keep backing up even after hydro jetting?
I had my main sewer line hydro jetted because of recurring backups and tree-root intrusion. The drains worked perfectly for a while, but several months later they started slowing down again.
The plumber said the line is old but still usable.
Could the roots be growing back this quickly? Would a sewer camera inspection show whether the problem is a damaged joint, a belly in the pipe, or another structural issue?
At what point should I consider trenchless pipe lining instead of continuing to hydro jet the line?

| Why does my sewer line keep backing up after hydro jetting?
If a sewer line continues to back up after hydro jetting, the cleaning itself may not be the problem. Hydro jetting removes roots, grease and buildup, but it doesn't repair a cracked pipe, separated joint or other structural defect. The current thread makes the same distinction between cleaning and permanent repair.
With recurring tree-root intrusion, a sewer camera inspection after cleaning is one of the most useful diagnostic steps.
With the pipe cleared, the camera can identify exactly where roots are entering and whether there are:
- cracked or separated joints;
- offset sections;
- damaged pipe;
- a collapsed area;
- a belly holding water;
- significant corrosion or deterioration.
If roots are entering through one or two relatively small defective joints and the rest of the pipe is structurally sound, periodic hydro jetting may still be a reasonable maintenance strategy. The existing discussion notes that minor joint offsets in an otherwise sound clay line can sometimes be managed this way.
However, if the same location develops root intrusion repeatedly, especially within months rather than years, it makes sense to compare the cost of repeated cleaning with a localized repair or trenchless lining.
A useful way to make the decision is to ask the plumber for the camera footage and identify:
Where are the roots entering? → Why are they entering? → Is the pipe structurally sound? → How often does the problem return?
If the answer is essentially “the pipe is intact and roots occasionally enter through a minor joint,” maintenance may be appropriate.
If the answer is “roots repeatedly enter through several damaged joints or cracks,” continuing to jet the same line indefinitely may only postpone the underlying repair.
In short: don't judge the sewer line only by how well it flows immediately after hydro jetting. The more important question is why the blockage keeps returning. A post-cleaning camera inspection can provide that answer and help determine whether maintenance, spot repair or trenchless lining makes the most sense.
