Plumbing Inspection in Waialua, HI
Only 15% of the people who own a home in Waialua bought it in 2018 or later. Where houses stay in the same hands, systems get older without anybody being obliged to look at them.
The one-paragraph answer
Waialua is settled, with 15% of owner households having moved in since 2018. The plumbing most likely to matter in a house held that long is the part no standard inspection covers, which is the buried sewer lateral.

When Waialua moved in
Where houses stay put, an inspection is a rare event, and the report on file — if there is one — describes a building that has since had a decade or more of ordinary use.
| Owner households in Waialua | Share of all owners |

Universe: 2,291 occupied housing units, of which 1,431 are owner-occupied. This counts when the CURRENT occupant moved in, so it measures recent moves as a share of the housing stock — not a rate of sales per year.
What the inspection will not cover
Wells, pumps, pressure tanks, storage tanks and filters are excluded by both standards. On a property with its own supply, the equipment feeding the whole house sits outside the inspection carried out on it.

What it is required to cover
The covered list is shorter than the excluded one and it is not thin. Every fixture run, every toilet flushed, the drain-waste-vent system described, the water heater and its venting examined, the shut-offs located. That is a real morning of work and it is worth knowing it happened.
The full covered list, and why the distinction between the two lists is the whole of reading a report properly.
What to do about it
Where a report says a condition was observed but its extent could not be established, that is the sentence to act on. It means the boundary of the inspection was reached, not that the problem is small.
Both standards are public. Start with the exclusions, then the obligations, and read the sewer scope separately — it is ordered on its own for a reason.
