What plumbing installation covers
Plumbing installation is any job that adds or changes pipes and fixtures rather than repairing what is there. Common examples in Dixon homes are a new kitchen sink and dishwasher hookup, a bathroom remodel, a laundry room, a hose bib or a line to a detached unit.
The work usually has two stages. Rough plumbing goes in before walls close, and the finish stage sets fixtures and connects them. Planning the fixture list early avoids opening finished walls later.

Dixon code rules that shape an installation
Source type: City of Dixon Building Division permit handouts.The City of Dixon's handouts cite the California Plumbing Code for interior drains. A sewer pipe inside a building needs a minimum slope of one quarter inch per foot, and the handouts say post-tension slabs must not be saw-cut. Fixtures must also be labeled to the CalGREEN limits: 1.28 gallons per flush for a toilet, 1.2 gallons per minute for a bathroom faucet, 1.8 for a kitchen faucet and 1.8 for a showerhead.
New work generally needs a permit, while simple repairs and clearing stoppages do not. Cleanouts are required at set points in a sewer line, such as a change of direction beyond 135 degrees and every 100 feet.
When a remodel moves fixtures, the City of Dixon Building Division reviews the plan and inspects the rough and finish stages. Your plumber coordinates those visits.
New work follows the California Plumbing Code, which is based on the Uniform Plumbing Code (UPC). The City of Dixon's handouts cite section 708.1 for drain slope and section 719.1 for cleanouts.
What to do before the installation day
Preparation keeps the work safe and the schedule short.
- Choose and buy fixtures before the rough-in so the plumber can match the openings.
- Clear the work area and cover floors.
- Know where the main water valve and the electrical panel are.
- Keep children and pets away from open walls and tools.
- Do not use new fixtures until the plumber has tested them.

Tell us the fixtures and the floor plan. A same-day appointment is offered when available.
Backflow assemblies and cross-connection protection
Backflow prevention keeps water from flowing backward into the drinking supply. Irrigation systems, fire sprinklers and some commercial equipment need a backflow assembly where the line connects to the supply.
Many water suppliers require these assemblies to be tested at installation and again on a regular schedule. Ask the City of Dixon water operations office which rules apply to your property, and see our commercial plumbing page for building owners.
Rough plumbing and finish plumbing
Knowing which stage is which helps you schedule other trades around the plumber.
Rough stage
- Supply and drain lines run through open walls.
- Vent pipes and cleanouts placed.
- Shower valves and tub drains set.
- Pressure test and inspection before walls close.
Finish stage
- Toilets, sinks and faucets set.
- Disposals and dishwashers connected.
- Supply lines and shutoff valves attached.
- Final leak test and walkthrough.
What changes the price of plumbing installation
Installation is quoted by scope. The plumber needs a plan or a walkthrough to put a number on it.
California requires a licensed contractor for work of $1,000 or more in labor and materials, and the down payment is capped at 10 percent of the price or $1,000, whichever is less. You also have a 3-day right to cancel, or 5 days if you are 65 or older.
For your real number, call (916) 312-0578 and describe the project.

Plumbing installation questions from Dixon homes
Adding or rearranging pipes and fixtures generally needs a permit through the City of Dixon Building Division. Like-for-like swaps and repairs are listed as exempt in the city's handouts.
The City of Dixon's handouts cite CalGREEN section 4.303: 1.2 gallons per minute for bathroom faucets, 1.8 for kitchen faucets and 1.8 for showerheads.
Yes, with a plan. Moving a drain affects slope, venting and sometimes the slab, so the plumber checks the layout before quoting.
It is a device that stops water from flowing backward into the drinking supply. Irrigation and some commercial systems need one, and the City of Dixon water operations office can tell you what applies.
Check the license at cslb.ca.gov, get a written contract and limit the down payment to 10 percent or $1,000, whichever is less.
