Plumbing Inspection in Conowingo, MD
Conowingo is settled. Only 12% of owner households moved in during 2018 or later, which means most of the plumbing here has not been looked at by anybody in a long time.
The one-paragraph answer
Homes in Conowingo rarely change hands — only 12% of owner households moved in during 2018 or later — so an inspection there is usually of a house somebody has lived in for years. The buried sewer lateral is still outside both published standards of practice.

When Conowingo moved in
Low turnover means the last inspection on most of these houses is old, and the systems in them have had years to change since. Nothing about a settled town makes plumbing age more slowly.
| Owner households in Conowingo | Share of all owners |
|---|---|
| Moved in 2021 or later | 2% |
| Moved in 2018–2020 | 11% |
| Moved in 2010–2017 | 29% |
| Moved in before 2010 | 58% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 1,608 occupied housing units, of which 1,421 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
ASHI asks for the predominant material of the water service, distribution and drain-waste-vent pipes to be described. Predominant is an honest word for a house that has been altered more than once, and it is not a complete answer about any single run.

What it is required to cover
The water heater is covered in more detail than most of the system: InterNACHI takes in the energy source, the venting connections, the temperature and pressure-relief valve, seismic bracing where it applies, and the labeled capacity. What it stops short of is operating any of it.
The covered list in full. Most people read the exclusions and stop; the two only mean anything against each other.
What to do about it
Two categories are worth chasing before you exchange: water somewhere it should not be, and anything the report could not see the end of. Both are open-ended, and open-ended is what moves a price.
The two standards are published in full and worth ten minutes: what is excluded, what is covered, and why the drains outside the house are a separate instruction.
