Signs Your Surrey Home's Sewer Line Needs a Camera Inspection

A sewer line problem almost never announces itself clearly. It shows up as a slow drain, a smell you cannot place, or a patch of lawn that stays green through a dry August. By the time it becomes obvious, it is usually a backup in the basement.

A camera inspection settles the question. A technician feeds a waterproof camera down the line and looks at the actual condition of the pipe, which turns guesswork into a decision. Here is when it is worth doing.

Drains that are slow everywhere at once

One slow fixture is a fixture problem. Hair in a shower trap, grease in a kitchen line, something lodged in a toilet.

When several fixtures are slow at the same time, particularly the ones lowest in the house, the restriction is downstream of all of them. That points at the main line rather than any individual drain, and no amount of work on the fixtures will change it.

Gurgling, and water appearing where it should not

Air displaced by a partial blockage has to escape somewhere. That produces gurgling from a toilet when the washing machine drains, or a bathtub that bubbles when someone flushes elsewhere in the house.

The more serious version is water backing up into the lowest fixture in the home when another one drains. That is a main line that has lost most of its capacity, and it is worth acting on before the next heavy rain rather than after.

Recurring backups in the same place

A line that has been cleared two or three times and blocks again in the same spot is telling you something specific. Clearing a blockage removes the material. It does not address what caused the material to accumulate there.

Usually there is a defect at that point: a root intrusion at a joint, a section that has sagged and holds water, an offset where two lengths of pipe no longer line up, or a partial collapse. Hydro jetting will clear it thoroughly, but a camera is what tells you whether clearing it is a permanent fix or a temporary one.

Mature trees and older neighbourhoods

Root intrusion is the most common cause of sewer line failure in this region, and it is not a sign of neglect. Roots seek moisture, and a sewer line is a reliable source. They enter through joints and hairline cracks, then expand until they fill the pipe.

Older Surrey and White Rock neighbourhoods are the usual setting, because they combine established trees with pipe that predates modern materials. Homes built before the mid-1970s often have clay or, in some cases, Orangeburg pipe, both of which are far more vulnerable to roots and to collapse than modern PVC.

Things in the yard that indicate a leak

The ground above a leaking sewer line behaves differently, and the signs are easy to miss if you are not looking for them:

• A strip of lawn that stays noticeably greener or grows faster than the area around it
• Soft or spongy ground along the line between the house and the street
• Sewage odour outdoors, particularly after rain
• A visible depression forming in the lawn or driveway
• An unexplained increase in pest activity around the yard

Before you buy, and before you renovate

The two best times to inspect a sewer line are the two when nothing is wrong.

Before purchasing a home, a camera inspection is inexpensive relative to what it can find. A standard home inspection does not include the buried sewer line, and a full replacement is a five-figure repair that becomes yours on closing day. On any property more than about forty years old, this is worth doing.

Before a renovation, the logic is similar. If you are about to pour a slab, finish a basement, or landscape over the line, knowing its condition first means you are not opening that work back up in three years.

What the inspection actually tells you

A camera run gives you specific information rather than a guess:

• The pipe material and its overall condition
• The exact location and depth of any defect, located from the surface
• Whether roots are present, and how far they have progressed
• Whether the line has bellied, offset, cracked, or partially collapsed
• Whether a blockage is a one-time obstruction or a symptom of a structural problem
• Whether the right response is cleaning, a spot repair, or replacement

That last point is what makes the inspection worth its cost. It is the difference between paying for a cleaning that solves the problem and paying for a cleaning that buys you eight months.
