A Saint Michael homeowner needed a full plumbing scope handled in one day. That meant new compression stops, a bathroom faucet and shower trim, a complete kitchen rebuild with code-compliant hammer arrestors for the dishwasher and fridge, a new garbage disposal with air switch, dishwasher installation with leak testing, and a gas line tied into the manifold for a future range.
Our licensed plumbing team finished the work, passed the city inspection at 3:25 PM the same afternoon, and tested every connection multiple times before leaving the home.

The homeowner wanted three rooms touched in a single visit. That's an efficient way to use a licensed plumber, but it requires careful sequencing so each room gets the attention it deserves. Here's how the project broke down:
Bathroom scope
Kitchen scope
Gas line scope
The whole project ran through the morning and early afternoon. The city inspector arrived, walked through every connection, and signed off at 3:25 PM. We texted the homeowner the Google review link before we drove away.
Most homeowners never think about the small valves under their sinks until one of them fails. Compression stops are the shutoff valves that let you turn off water to a single fixture without killing water to the whole house. When stops are old, corroded, or installed incorrectly, they fail at the worst possible time. We replace them as part of any major fixture install because new fixtures deserve new shutoffs.
Hammer arrestors solve a different problem. When a dishwasher or washing machine slams its solenoid valve closed, the water in the supply line wants to keep moving. That energy has to go somewhere, so it travels back through the pipe as a pressure spike. You hear it as a loud bang in the wall. Over time, that pressure spike loosens fittings, stresses solder joints, and shortens the life of every fixture upstream. Minnesota plumbing code requires hammer arrestors on quick-closing valves for exactly this reason.
You can read more about how this works in our guide on Minnesota plumbing code requirements, which covers the rules that govern any kitchen or bathroom project in Hennepin and Wright counties. For background on why arrestors exist, Bob Vila has a clear explanation of water hammer and how to spot it in your own home.
The bathroom portion took the longest because every connection had to be tested twice. After installing new compression stops on the supply lines, we installed the new bathroom faucet and drain assembly, then filled the sink and drained it five times. That's not just a checklist item. Slow leaks at the drain trap often don't show up until water has been sitting in the line for a few minutes, so repeated fills are the only reliable test.
For the shower trim, we ran five gallons through the shower head while watching every visible connection. We checked the temperature limit stop on the mixing valve to make sure it was set correctly before sealing the faceplate. If you ever wondered why a proper shower install takes longer than expected, this is why. There are at least six places water can leak from a single shower trim kit, and a licensed plumber checks every one of them. For deeper context on this, Mr. Rooter has a useful breakdown of shower valve types and why mixing valves matter for both comfort and safety.

The kitchen scope was the most involved part of this Saint Michael project. We started by installing all new shutoff stops at the supply lines. Then we added hammer arrestors on the dishwasher line and the fridge line, because both run to appliances with quick-closing valves and Minnesota code requires the protection.
Next came the kitchen faucet, drain, and garbage disposal. The disposal was wired through an air switch, which is a small button mounted on the counter that uses an air pulse to activate the disposal instead of a wall switch. Air switches are safer because there's no electrical connection near water, and they look cleaner on the countertop.
The dishwasher install required a few extra steps. We connected the supply, drain, and electrical, then ran the unit through multiple full cycles while we watched the dishwasher 90 — that's the 90-degree drain elbow on the front of the unit, which is the most common leak point on a new install. After two clean cycles with no drips, we cleared the work area.

This was one of the smarter calls the homeowner made. They had decided to install an electric range for now, but they wanted the gas line in place in case they switched to gas down the road. Running a gas line during a project that already involves opening walls and floors is far cheaper than running one later as a one-off job.
We tied the new branch line into the home's existing gas manifold, capped it safely near the stove location, and tested the entire system for leaks. Gas line testing involves charging the line with air pressure and watching a gauge for any drop over a set period, then brushing every joint with a soap solution to look for bubbles. A leaky fitting produces bubbles immediately, and we don't leave until every connection is clean.
The Minnesota Department of Labor and Industry plumbing code governs all gas line work in the state, and only properly licensed plumbers are allowed to tie into a home's gas system. Unlicensed contractors who do gas work create real liability for homeowners. We wrote more about that in our article on why you need a licensed plumber for a new gas range or dryer, which covers the same code issues that came up on this Saint Michael install. Our full gas line installation and repair page details the kind of work we do across the Maple Grove area.

The inspection passed at 3:25 PM. That matters more than it sounds.
When a city inspector walks a job and signs off without a punch list, it means every connection met code, every required component was installed correctly, and the documentation matched the work. Inspectors don't issue same-day passes for sloppy work. They issue corrections, then come back days later for a re-inspection that costs the homeowner more time and the contractor more billable hours.
A licensed plumber who builds the job to code the first time saves the homeowner from re-inspection fees, return visits, and the anxiety of wondering whether the work was actually done right. For more on what a good inspection looks like, our blog on what to expect during a professional plumbing home inspection in Maple Grove walks through the process.
