Plain English
Pipe Repair Terms, Translated
Contractors talk in shorthand, and homeowners end up nodding along. Here is every term you are likely to hear during an inspection or an estimate, defined the way we would explain it across your kitchen table.
32 of 32 terms shown
A
- All-Inclusive Proposal
- A quote that bundles everything, inspection, descaling, permits, lining, verification, and warranty, into one number. If a proposal is not all-inclusive, ask what shows up later as an extra.
- ASTM Standard
- National engineering standards that define how a repair must perform. Structural pipe lining meets ASTM F1216, F1743, or F2019. A contractor who cannot name their standard is not installing to one.
B
- Branch Line
- The smaller pipe that carries one fixture's wastewater, a sink, a toilet, a shower, to the main building drain.
C
- Camera Inspection
- Running a high-definition camera through the drain system to record its real condition. The foundation of every honest recommendation.
- Cast Iron
- The heavy, dark metal drain pipe standard in Florida homes built before 1980. Strong when new, and now at or past its 40 to 50 year design life everywhere it was installed.
- Change Order
- A mid-project price increase. Common where proposals were vague. Rare where footage was measured and the proposal was all-inclusive.
- CIPP (Cured-In-Place Pipe)
- The trenchless method that builds a new structural pipe inside the old one. A resin-saturated liner goes in soft, inflates against the pipe wall, and cures hard.
- Class I Repair
- The top structural repair class. The repair works as a standalone pipe even if the original pipe fails completely. UV-CIPP lining is Class I, which is why it carries a lifetime warranty.
- Cleanout
- A capped access point into the drain system. The door every camera, cleaning tool, and liner enters through. Keep yours reachable.
- Cure
- The step that hardens a soft, resin-saturated liner into a rigid structural pipe. The cure method controls the quality of the finished pipe.
D
- Descaling
- Mechanically removing the hardened rust and mineral crust from inside a cast iron pipe using cutting chains and milling tools, restoring the pipe's original diameter and preparing it for lining.
- Drain, Waste, and Vent (DWV)
- The full system of pipes that carries wastewater out of the home and keeps air pressure balanced so everything flows and traps stay sealed.
E
- Epoxy Coating
- A sprayed resin layer inside a pipe. A surface treatment, not a structure. Classified at the bottom of the repair scale and warrantied accordingly.
F
- Four-Point Inspection
- An insurance-ordered inspection of a home's four major systems, roof, electrical, plumbing, and HVAC, commonly requested on older Florida homes.
H
- Host Pipe
- The original pipe a liner is installed inside. After lining, the host pipe becomes the outer shell and the liner does the work.
- Hybrid Repair
- Combining a targeted spot repair on a failed section with lining for the rest of the run. The standard honest answer for systems with localized collapse.
- Hydro Jetting
- High-pressure water cleaning that clears grease, roots, and soft blockages. Effective clearing, temporary in aging cast iron, and unable to remove hardened scale.
L
- Lateral
- The pipe that carries wastewater from your home to the municipal sewer, usually running under the yard toward the street. It ages like everything else and can be lined the same way.
- Liner
- The resin-saturated structural tube installed inside the old pipe. Once cured, it is the new pipe.
- Locator
- The device that tracks the camera head underground, mapping exactly where the pipe runs, how deep it sits, and where each problem lives.
M
- Main Building Drain
- The largest drain pipe in the home, collecting every branch line and carrying everything to the lateral. In pre-1980 Florida homes it usually runs under the slab.
- Manual Review
- What happens when an address does not pass automated qualification checks. A person looks at it instead of a database. If our form offers you one, take it.
R
- Resin
- The engineered material that saturates the liner and hardens during the cure into the structural pipe wall.
S
- Slab-on-Grade
- The Florida standard of building a home on a poured concrete slab, with the drain pipes buried beneath it. The reason traditional pipe replacement requires demolition, and the reason trenchless repair exists.
- Spot Repair
- Excavating and fixing one failed section of pipe rather than the whole run. Legitimate when the camera proves the damage is truly isolated.
T
- Trap
- The curved section under every fixture that holds water and blocks sewer gas. A dry trap in an unused drain is the cheap, innocent cause of some sewer smells.
- Trenchless
- Any repair method that works through existing access points instead of digging. Lining is the trenchless method for permanent structural repair.
- Tuberculation
- The plumber's term for the rust barnacles that grow on the inside of aging cast iron, narrowing the pipe and snagging debris. The root cause behind most recurring clogs.
U
- UV-CIPP
- Cured-in-place pipe cured with ultraviolet LED light. The cure completes in minutes with precision-controlled energy, unaffected by weather, and verified in real time. The only cure method we install.
V
- Vent Stack
- The vertical pipe that runs through the roof and keeps air pressure balanced in the drain system. Blocked vents are one innocent cause of gurgling.
W
- Warranty Transfer
- Moving warranty coverage to a home's new owner. Ours transfers one time when registered in writing within thirty days of closing, with a one-time administrative fee.
Y
- Year Built
- The single fastest predictor of what is under a Florida slab. Before 1980, assume cast iron until a camera proves otherwise. Your county property appraiser lists it free.
