When it’s the main line,
not the sink
Several fixtures gurgling or backing up at the same time is the signature of a main-line blockage. It is also a health issue as much as a plumbing one, which is why it does not wait for Monday.
The signs it is the main line
One fixture is a fixture problem. Several at once is almost always the run they all share.
More than one fixture backing up
The clearest signal there is. The blockage is downstream of everything that is misbehaving.
Flush a toilet, the shower fills
Water taking the path of least resistance because the main cannot take it.
Sewer odour indoors or in the yard
Waste sitting where it should be moving, or escaping through a fault in the line.
Gurgling from several drains
Air displacing through traps as the blocked main struggles to clear.
The lowest fixtures go first
Ground-floor showers and floor drains back up before anything upstairs does.
It has happened before
Repeat main-line backups point at roots or a structural fault rather than what got flushed.
What we do about it
Stop it getting worse, clear it, then find out whether it is going to happen again.
Stop adding to it
First instruction on the phone: stop running water throughout the house. Every flush and every load adds to what has nowhere to go.
Access and assess
Through the cleanout where there is one. How far down the blockage sits tells us a lot before we touch it.
Clear the line
With the method suited to the pipe and to what is blocking it — roots, grease, solids or a collapsed section behave very differently.
Tell you what caused it
One-off, roots, or a line with a structural fault. If it is the third, you get an honest quote for the repair rather than a promise it will be fine.

Why a main-line backup gets treated differently
A slow sink is an inconvenience. Sewage coming up into a shower pan is a contamination problem in a room your family uses, and it does not improve while it waits. That is why this is one of the calls we will come out on at night.
It is also why we are careful to distinguish the one-off from the pattern. A main line that blocks once because of what went down it is a different situation from one that blocks every spring because roots are into a cracked joint — and only one of those is solved by clearing it.
- Main line blockages affecting multiple fixtures
- Root intrusion clearing — and finding the entry point
- Grease and solids build-up in the main run
- Access through existing cleanouts wherever possible
- Honest assessment of whether the line has a structural fault
- Repair quoted separately if the pipe is the cause
- Affected area left clean
Roots, clay and older lines
Two things drive most of the main-line trouble we see around Boerne. The first is ground movement: expansive clay works joints apart season by season, and every opening it creates is an invitation. The second is what follows — roots, which will travel a long way toward a water source and then expand inside the pipe they found it in.
Older properties around Comfort, central Boerne and the established San Antonio neighbourhoods we cover carry the added factor of original drain material that has already had decades of that treatment.

Sewer Cleaning questions
Still not sure?
Describe it on the phone and we'll tell you straight whether it needs us.
That is the signature of a main-line blockage rather than a fixture problem. The obstruction is downstream of everything that is misbehaving, which is why they are all affected together.
No. Stop running water throughout the house — every flush, shower and load of laundry adds to what already has nowhere to go, and that is what turns a backup into a clean-up.
We treat it as one. It is a health issue as much as a plumbing one, and it does not get better on its own. We take these calls on nights and weekends.
Most often roots getting into a joint that ground movement has opened up, plus grease and solids accumulating in the run. Expansive clay soil is the underlying cause of a lot of it.
If it was a one-off blockage, yes. If roots or a structural fault caused it, clearing buys you time rather than a solution — and we will tell you which situation you are in.
