What a plumbing installation covers
New plumbing falls into three jobs: supply lines that bring water to the fixture, drain lines that carry waste away, and vents that let the drain run. All three must slope, size and connect correctly under Minnesota's plumbing code in chapter 4714.
We install sinks, tubs, showers, toilets, washing machine boxes, laundry sinks, outdoor spigots and appliance hookups. When a project needs a new water heater, our water heater installation page covers that piece.
Common projects and what they need
A good plan checks these before demo.
| Project | Plumbing needs | Common catch |
|---|---|---|
| Basement bathroom | Drain lower than the main may need a pump | Floor concrete cutting for the drain |
| Kitchen remodel | Supply, drain, dishwasher and disposal hookups | Old galvanized supply lines |
| Laundry room move | Supply box, standpipe and vent | Drain distance and venting |
| Bathroom addition | Supply, drain, vent and hot water capacity | Water heater size |
A basement bath below the sewer line level may need a sewage ejector, which is related to sump pump work.
Permits and who can do the work
The City of South St. Paul Building Permits and Inspections office issues plumbing permits. Minnesota law allows owners to do plumbing in their own homes unless local ordinance forbids it, and a licensed plumber is required for most other work.
The Minnesota Department of Labor and Industry runs a free license lookup, so you can verify a plumber's credentials. We handle permit paperwork for work we perform, and we schedule the inspection.

Questions to ask any plumber before you start
Good answers here prevent change orders later.
- Who pulls the permit, and is the fee included?

- What fixtures and parts are included in the price?
- How are surprises such as corroded pipe handled?
- What is the warranty on labor and on the fixtures?
What happens at rough-in inspection
Before walls close, an inspector looks at the supply lines, the drains and the vents. The pipes are usually under pressure or filled with water to test for leaks. This is the point where an error is cheap to fix.
Schedule the inspection early, because inspector availability can set the pace of the whole remodel. Take photos of every wall before it is covered, so you know where pipes run in the future.
