Smell gas? Leave first, then call
If you smell gas, leave the building right away and call your gas utility or 911 from outside. Do this before you call a plumber. Do not flip switches, light anything or try to find the leak yourself, because a gas problem is handled by the gas utility and emergency crews first.
What a plumbing installation job covers
New plumbing falls into three groups: fixtures you can see, pipes in the walls and floors, and the connections to supply and drain. Examples are a new vanity and toilet, a kitchen sink with disposal and dishwasher hookups, a laundry box, a water heater line or a gas stub for a range. Each one needs the right pipe size, a vent, and a place for water to go.
In Covington, KY the most common planned jobs are bathroom adds, kitchen updates and appliance hookups in older houses. The plumber starts by looking at what is already behind the wall, which decides how much of the job is simple and how much is repair.
Typical jobs we install
A few of the jobs homeowners ask about most.
Bathroom fixtures
Toilets, vanities, tubs and showers set on proper supply, drain and vent connections.

Sink, faucet, disposal, dishwasher and ice maker lines in the right order.
Laundry hookups
Washer box with shutoff valves and a standpipe that drains fast enough.
Outdoor spigots

From rough-in to final inspection
Most installs follow the same path.
- 1
Plan the layout
The plumber measures, checks existing pipe size and venting, and picks fixture locations that drain properly.
- 2
Rough-in
Supply and drain pipes are run inside open walls or floors before drywall goes up. This is the stage inspectors usually want to see.
- 3
Test and inspect
Lines are pressure-tested, held for 15 minutes under the Kentucky homeowner guidance, and inspected before anything is concealed.
- 4
Set fixtures
Fixtures are connected, shutoffs are tested, and the system is run to check for leaks before the plumber leaves.
Permits and inspections in Covington
The Kentucky Department of Housing, Buildings and Construction says new installations, moving fixtures, water service from the meter to the house, and house sewers need a plumbing permit. It also says work that will be covered by concrete, put inside walls or buried underground must be inspected before it is covered. Permit rules vary, so ask the Kentucky Division of Plumbing or the local plumbing inspector before your project starts.
Kentucky's plumbing code is set by the state under KRS 318.130, and you can check a plumber's license through the Division of Plumbing. In older Covington houses, where bathrooms were added decades after the original build, the existing drain and vent often decide what is possible.
Gas line work: why it comes with extra rules
Installing or moving gas piping is different from water work because a small mistake can be dangerous. A plumber will isolate the line, size it for the appliance load, and test it for leaks before the appliance is turned on. The inspection step matters more here than anywhere else.
If you notice a gas odor at any point after an install, the rule does not change: leave the building and call your gas utility or 911. We do not promise a response time on a gas call. The utility and emergency crews come first, and a plumber can return for repair once the line is safe.
Backflow prevention and testing
A backflow preventer is a valve assembly that keeps used water from flowing backward into the drinking supply. Irrigation systems, lawn sprinklers, fire lines and some commercial equipment use them. Whether a device must be tested on a schedule depends on the device and who supplies your water.
Northern Kentucky Water District serves 99 percent of Kenton County households, so ask NKWD whether your installation needs testing. A licensed plumber can install the assembly, test it and give you the record. For shops and restaurants, our commercial plumbing service handles the same work.
New construction and remodels
New construction plumbing is laid out with the framing, in stages: underground drains, rough-in in the walls, then fixtures. The sequence is inspected before concrete or drywall goes over it. For a remodel, the plumber works around what is already there, so some jobs call for a repipe before new fixtures are added.
What affects the price of installation
Why two installs of the same fixture can price very differently.
Frequently asked questions
It depends on the fixture, the distance to existing pipes, wall access, permits and any gas or water service work. You get a clear price before work starts.
Leave the building right away and call your gas utility or 911 from outside. Do that before calling a plumber. A plumber can help after the utility declares the line safe.
New installations and moving fixtures generally need a plumbing permit under Kentucky guidance. Permit rules vary, so ask the Kentucky Division of Plumbing or the local plumbing inspector.
Often yes. A plumber checks the fixture, the shutoffs and the connections first. If a part is missing or the fixture is not compatible, you will hear that before work starts.
That depends on the device and local requirements. Ask NKWD or the plumbing inspector, and a licensed plumber can test and record the result.
