A plumbing inspection in San Jose checks the supply pipe material and condition, water pressure, drains and venting, the water heater, visible gas piping, fixtures and shutoffs, and usually includes a sewer camera run; it is most useful before buying a house and on older homes once every few years.

What an inspection tells you
General home inspectors look at plumbing briefly. A plumbing inspection goes further: we identify pipe materials room by room, test pressure and flow, check every accessible valve, look for past leaks and repairs, and assess the water heater's age and installation.
The result is a written list of what is sound, what is aging, and what needs attention now, with the reasons. It is the difference between guessing at a repair budget and planning one.
Included
What the inspection covers
- Supply pipe material and condition
- Water pressure and regulator
- Main shutoff and fixture stops
- Water heater installation and age
- Drains, vents and traps
- Visible gas piping
- Sewer camera run
Pre-purchase inspection
Before buying, you want to know whether the house still has galvanized supply lines, cast iron drains or a lateral that will fail the point-of-sale test. We inspect the supply and drain systems, run the sewer camera, check the heater and gas piping, and record what we find with photos. The report gives you facts to negotiate with or to plan the first year's work, and it is written for a buyer rather than a plumber, with each item ranked by how soon it needs attention.
Annual whole-home check
For homes you already own, an annual or periodic check catches the slow failures: a stop valve that no longer closes, a regulator letting pressure creep, a heater with a spent anode, a small drip under a sink. We work through the house with a checklist, exercise the main shutoff, test pressure, and flush the heater if needed. Owners of older homes find it most useful, because small problems there tend to arrive together, and one visit that finds them all costs less than several emergency calls spread over a year.
Insurance and rental turnover
Insurers sometimes ask about pipe materials and water heater age, and landlords want a unit checked between tenants. We inspect and document shutoffs, supply lines to toilets and appliances, heater strapping and relief valve piping, drains and visible leaks, and give you a written record. Replacing rubber washer hoses, plastic toilet supplies and seized valves during the same visit is often the most useful part of a turnover, because those are the parts that fail while a unit sits empty and nobody is there to notice the water.
Local context
What San Jose's housing age means for an inspection
Across San Jose the median home dates to 1978, and most of the city's single-family houses went up between 1950 and 1975. Galvanized steel from that era typically lasts 50 to 70 years, and even 1960s copper can pinhole after decades of Bay Area water chemistry. So in an inspection here, identifying the supply material and its age is usually the most valuable finding, because it tells you whether a repipe is years away or already due.
