Schoenwalder Plumbing, a Waukesha plumbing company founded in 1945, repairs leaks, drains, sewer lines and water heaters for New Berlin homes.
New Berlin is on our list of 14 Waukesha County service communities. We work out of one shop, at 1720 Dolphin Drive in Waukesha, and you can reach the office at 262-542-7908 on weekdays from 7:30 a.m. to 4:30 p.m.





Schoenwalder Plumbing fixes leaking pipes and faucets, clogged drains, running toilets and old water heaters in New Berlin, and checks sewer lines by camera.
Every job runs under master plumber license MP 224276, held by [CLIENT DATA: license holder’s name]. Here’s the work, with a page on each if you want the detail:
| Job | What we do | More |
|---|---|---|
| Leaks | pipe, faucet and fixture repairs, and new toilets, sinks and disposals | — |
| Drains | clearing clogged kitchen, bathroom and floor lines | drain cleaning |
| Sewer lines | inspection and tree root removal | video sewer inspection |
| Water heaters | tank and tankless repair and replacement | water heater |
| Basements | sump pump installation, service and repair | — |
| Water quality | water conditioning and filtration | softeners and reverse osmosis |
| Safety devices | device testing and compliance | backflow preventer testing |
New Berlin's water utility buys treated Lake Michigan water from Milwaukee, and Milwaukee Water Works rates that water as moderately hard.
The switch came after the Wisconsin DNR approved New Berlin’s Lake Michigan diversion under the Great Lakes Compact. The city’s diversion report to the DNR dates Lake Michigan service to July 2009.

So what does that mean at your tap? Milwaukee Water Works puts its water at 8.01 grains per gallon on its water hardness page, and it says softeners aren’t necessary for residential use. If your home has a softener that was set up for the old supply, its hardness setting deserves a look. One set too high wastes salt and water. Worth a check.
Then it’s a different story, and testing comes first. We test well water, install treatment systems sized to the results, and service well pumps under Wisconsin DNR pump installer license PI 7661.
A sewer camera inspection shows New Berlin buyers the underground pipe a home inspection skips: roots, cracks, sags and joints that have shifted.
A home inspection looks at what you can see, and the sewer lateral (the pipe from the house to the city main) is underground. A camera shows its condition before you own it. The same camera works on a slow kitchen or laundry line too.
Responsibility for a lateral depends on local rules, so ask the city who owns which section before you close. A video sewer inspection gives you a recording of the line and a clear picture of its condition while you can still ask questions.

We have used Schoenwalder 3 different times and each time they were prompt, friendly and efficient. Today plumber Vince diagnosed and fixed a slow water leak behind our walls. We couldn’t figure out where the water drips were coming from but Vince solved the mystery and completed the repairs efficiently and at a fair price. Highly recommend Schoenwalder.Posted on Google![]()

Received same day service when I called in the morning, very reliable and professional staff. The plumber was knowledgeable and pointed out all other parts that needed replacement while installing my new kitchen faucet. He was very thorough and did the work in a timely manner. Would highly recommend this company for your plumbing needs!Posted on Google![]()

Schoenwalders are the best! They were at the house the next morning and fixed the problem in less than an hour. They only charged me a fraction of what I expected to pay. I was super happy with the service they provided, and I would recommend them to anyone in need of a plumber. Friendly, professional, priced reasonably.Posted on Google![]()
