Sixty-year-old houses and the drains under them
Hopkins housing is old, and the city's own housing plan says so. About 60 percent of owner-occupied homes are at least 60 years old. That age predicts the calls we dispatch for: clay and cast iron house drains with root-filled joints, galvanized supply lines narrowed by rust, and original traps that clog under a heavy load. A drain camera shows which one you have before anyone cuts a floor.
Renters live in a different era. The same plan says two-thirds of renter-occupied housing went up between 1960 and 1989, so many apartment buildings run cast iron stacks and shared building drains. When two units back up together, the blockage sits in the shared line, not in a sink. Managers who say that on the first call save a visit spent cabling the wrong fixture.
Hopkins issues plumbing permits through its Inspections Division, and the work is held to the standards of the Minnesota Plumbing Code, Minnesota Rules chapter 4714.
Hopkins building types and the first thing to check
Match your building to a row below. The last column is what a plumber usually does before any repair is priced.
| Building type | Pipes to expect | First step |
|---|---|---|
| House from before 1970. | Clay or cast iron drains, galvanized supply. | Camera the main drain line. |
| Apartment from 1960 to 1989. | Cast iron stacks, shared building drains. | Ask neighbors if they back up too. |
| Condo or patio home. | Shared mains, often owned by the association. | Confirm who owns the line. |
| Main Street storefront. | Old floor drains, repairs from several eras. | Trace the drain before cabling. |
| Any age, brown tap water. | Sediment from the city main. | Run cold water, see below. |
In complexes such as Meadow Creek Condominiums or Westbrooke Patio Homes, ask the association which section of drain belongs to your unit. That answer decides who calls us and who pays.
Clearing the clog first, repairing the sewer when the camera says so
Most Hopkins backups start as a clog and stay a clog. A cable or a hydro jetter clears grease, scale and roots, and a drain cleaning visit is the usual first move for a slow tub or a gurgling floor drain near downtown in 55343.
Some do not stay clogs. If roots return within months, or the camera shows a sagging section that holds water or a cracked clay joint, cleaning only buys time. That is when sewer line repair enters, by spot repair, lining or replacement, depending on what the picture shows. In older blocks of 55305, a repeat clog is often a failing pipe, which is why the camera comes first.
Keep rain out of the sanitary line. Hopkins stormwater drains through the storm sewer to the Minnehaha Creek and Nine Mile Creek watersheds, a separate system from the sanitary sewer. A downspout or sump discharge tied to the wrong one can overload a house drain in a storm, so tell the plumber where your gutters and sump pump empty.
Why the tap runs brown, and when to worry
Hopkins runs its own water system from three wells about 500 feet deep. The city filters iron, but says some remains and coats the inside of the water main pipes. Hydrant flushing, main breaks, service leaks and fire use can knock those deposits loose, and brown or rusty water shows up at your tap.
Run the cold tap for a few minutes until it clears. Skip the hot tap, which would pull sediment into your water heater. If the water clears, you do not need a plumber. If it stays brown, or only one fixture shows it, the cause may be your own pipes, and that is a call for the 24/7 line.
The city also states that its water measures 21 grains of hardness. Expect scale on faucet aerators and inside tank heaters, and a water heater repair call often traces back to that buildup.
Main Street buildings inside the historic district
The Hopkins Commercial Historic District runs along Main Street from 8th to 11th Avenues and joined the National Register in 2022. Buildings there are old, and their basements hold floor drains and patched lines from several decades. For a shop or restaurant owner, the useful step is to find the floor drains and the water shutoff now, since a plumber starts at exactly those points.
A listing is a recognition, not a plumbing rule, so ask the City of Hopkins whether it changes anything for your project. The 24/7 line takes commercial plumbing calls the same way it takes house calls.
Hopkins at a glance for the 24/7 line
A few local facts shape how we diagnose a call before the truck arrives.
Housing
The city counts about 9,184 homes, and the vast majority are at least 50 years old. Expect original drains and older supply lines, so a camera look is routine.
Water and sewer
City Water & Sewer under Public Works runs the water main, sanitary sewer and storm sewer. Ask the city where its pipe ends and yours begins before assuming a backup is private.
Where we take calls
We take drain cleaning calls in 55343 around downtown and Burnes Park, sewer line repair calls in 55305, and both in the Hopkins-aliased part of 55345 that Minnetonka shares.
Emergency hours
Emergency dispatch to Hopkins is available around the clock, including nights, holidays and festival weekends when the town fills up. The same line also dispatches to nearby Eden Prairie and Plymouth.
The 180-day permit clock
The City of Hopkins Inspections Division issues plumbing permits. Its form says a permit becomes null and void if the authorized work does not begin within 180 days of the date it was issued. Pull the permit when you are ready to schedule, not months ahead, and ask the Inspections Division whether your repair needs one.
Before we arrive at your Hopkins home
Four quick steps limit the damage while the plumber is on the way.
Find the main shutoff
In a mid-century Hopkins house the main valve usually sits in the basement where the water line enters. Old gate valves can be stiff, so turn slowly and stop if it resists.
Kill power to wet areas
If a basement floor drain is backing up, switch off the breakers for the basement outlets and stay off wet carpet. Leave the furnace alone if water is near it.
Clear the area
Move boxes off the basement floor and away from the drain. In an apartment building, warn the neighbors below and make sure the utility room is open.
Call the 24/7 line
Say your building type, which fixtures are affected and whether neighbors are backing up. That tells dispatch whether the job involves a shared drain.
Questions from Hopkins homeowners
Yes. Downtown, Main Street and Burnes Park fall in 55343, the primary Hopkins ZIP, and 55305 also carries the Hopkins name. The western edge uses 55345, whose official name is Minnetonka but which accepts Hopkins as an alias, and Minnetonka shares that ZIP. Neighborhoods such as Bellgrove, Minnehaha Oaks and The Avenues are all in range.
Yes. The 24/7 line dispatches licensed plumbers to Hopkins at night, on weekends and on holidays. Same-day appointments are available when the schedule allows for non-emergency work.
Usually not. The city says iron deposits in its mains can be stirred up by hydrant flushing, main breaks or fire use. Run only the cold tap until it clears, and call if it stays brown or only one faucet is affected.
The city's form says a permit goes null and void if the work does not start within 180 days of issue. Ask the Hopkins Inspections Division about timing for your project.
Call the 24/7 line and say that several units are affected. A shared stack or building drain is the likely spot, and the plumber will bring a machine cable or jetter sized for it. The property owner decides on any repair that follows.
Not always. The city runs the sanitary sewer in the street, but the pipe from your house to the main is yours. A camera on your side shows whether the blockage is yours, and if it is not, the plumber will tell you to contact the city.
