A plumbing inspection in Knoxville, TN checks every system a general home inspection only skims: supply pipe material and pressure, drains and venting, the water heater's age and safety devices, the main shutoff and fixture stops, and visible leaks. It ends with a written list sorted into fix now, fix soon, and fine as is.

What a Plumber Sees That a General Inspector Might Not
General home inspectors cover a lot of ground in a few hours, and plumbing gets a quick look: run the faucets, flush the toilets, check under sinks. A plumbing inspection goes further. We identify pipe materials wherever they can be seen, test static pressure at a hose bib, check the heater's relief valve and venting, and work shutoffs nobody has touched in years.
The report sorts findings by urgency instead of burying you in minor notes. If drains are slow or the house is old enough for clay or Orangeburg, we recommend adding a camera run through the sewer, because the most expensive plumbing in a house is the part nobody can see.

- Static water pressure tested
- Every fixture run, drained and checked for leaks
- Toilets checked for silent leaks and loose bases
- Water heater age, relief valve, venting and strapping
- Main shutoff and fixture stops exercised
- Written report sorted by urgency
Pre-Purchase Plumbing Inspection
Buying a house is when an inspection pays the most, because every finding is still negotiable. We look for the expensive items first: polybutylene or galvanized supply lines, a water heater near the end of its life, active leaks, signs of past water damage, a main shutoff that will not close, and drain problems. The report is written for a buyer, with findings worth taking back to the seller separated from simple maintenance. Scheduling it inside your inspection period keeps every option open.
Annual Whole-Home Plumbing Check
For owners, a yearly check catches slow problems before they become fast ones: a toilet flapper leaking silently, a supply hose bulging behind the washer, a relief valve that has started to weep, corrosion forming at a dielectric union. We test pressure against what the regulator should hold, look for signs of thermal expansion trouble, and exercise the shutoff valves so they still work on the day you need them. Most findings are small and cheap, which is the whole point of looking early.
Water Heater and Shutoff Review
The water heater and the main shutoff are the two items that turn a leak into a flood or keep it from becoming one, so they get their own section of the report. On the heater we read its age from the serial number and check the relief valve and discharge pipe, venting on gas units, strapping, the expansion tank and any rust at fittings. On the shutoffs we confirm the main closes fully and every fixture stop turns, since a seized valve is only ever discovered at the worst moment.

Plumbing Inspection Questions From Knoxville Homeowners
How is this different from a home inspection?
A general inspection covers the whole house briefly; a plumbing inspection looks closely at pipe materials, pressure, drains, the heater and shutoffs.
How long does it take?
Most homes are done in one visit. Larger or older homes with crawlspaces take longer.
Does it include the sewer line?
Inside drains are checked. The buried lateral needs a separate camera inspection, which we recommend on older homes.
Can you test my water?
We check hardness at the tap; testing for lead or bacteria goes to a certified lab, and we can tell you how to request it.
Will you fix what you find?
Only if you ask. The report stands on its own, and you can use it with any contractor.
What does polybutylene look like?
Usually gray flexible plastic pipe marked PB, common in homes built from the late 1970s into the 1990s; see whole-house repiping.
