Sewer Line Repair in Sammamish, WA
In Sammamish the sewer lateral — the run from the house to the public main — belongs to whoever owns the property, not to the utility. There are 18,175 occupied homes here, and across all the housing the median build year is 1995 — the best single clue to what the pipe is made of and how it tends to fail.
In short
On plastic the material is rarely the answer, and plastic is what Sammamish housing of about 1995 will have beneath it. That moves the question to how the run was laid: a belly holds water, and a flat section drops solids.

What went in the ground around 1995
A lateral laid in Sammamish in that period is most likely PVC or ABS, solvent-welded, and effectively immune to corrosion and to roots at the joint. A repeated backup here points at fall and alignment, not material. More on plastic laterals.
What a camera survey should settle here
Solvent-welded pipe rarely fails at the joint, so the survey is measuring fall and looking for standing water. The full picture on plastic laterals.
Sammamish is the 22nd largest block of laterals we cover in Washington, carrying about 1.0% of the 1,780,641 homes on our WA list, and its housing runs older than 21% of the WA towns we route. Age concentration matters on a lateral: where a whole street went in one season, the failures arrive in one season too.
86% of homes here are owner-occupied — 26 points above the WA figure. That matters more on a lateral than on almost any other pipe in the house: the run from the building to the main is the property owner’s to repair, and a landlord and a resident owner do not find that out at the same speed.
Median household income across Sammamish ZIP codes is $242,007 — the relevant figure for a job no insurer and no utility is going to split.

Before anyone digs in Sammamish, get the run on camera — and ask about fall rather than material, because solvent-welded pipe rarely fails at the joint. What the recording should show you.
