Plumbing in Sherburne County, the short answer
PlumbTek plumbs homes in Sherburne County from its main office in Big Lake, covering Elk River, the county seat (55330), along with Becker, Zimmerman, Clear Lake and the rural townships. Private wells are common here, so pumps, pressure tanks, softeners and iron filters make up much of the work, along with sump pumps, water heaters and basement bathrooms.
Why is well water the center of Sherburne County plumbing?
Outside the city water systems in Elk River and Big Lake, a large share of Sherburne County homes draw from private wells. That means a submersible pump down the well, a pressure tank and switch in the basement, and treatment equipment to deal with what comes up. When any piece fails, the whole house loses water, so these are often urgent calls.
The water itself is usually hard and carries iron, which leaves orange stains in sinks and toilets and coats the inside of water heaters. A softener alone sometimes can't keep up with heavy iron, so many homes run an iron filter ahead of it. Matching the equipment to an actual water test is what keeps both units working and avoids buying more than you need.

What do Big Lake, Becker and Zimmerman homes run into?
Big Lake, Becker and Zimmerman have added many newer subdivisions alongside older lake homes. The newer houses have plastic piping that holds up well, but they also have sump pits, basement bathrooms that may need an ejector pump, and water heaters working against cold well water in winter. Lake properties add seasonal concerns, like cabins and three-season rooms that need draining before a hard freeze.
When PlumbTek drives out from the Big Lake office to a rural call, the first checks are simple: pressure at the tank, the switch contacts, the age of the heater and the condition of the softener. Many problems that look serious, like no water upstairs, trace back to a failed pressure switch or a clogged sediment filter that costs little to fix.
Advice for well owners and lake homes in Sherburne County
- Test the well water every year. An annual water test tells you hardness, iron and whether bacteria are present. It also shows whether your softener and filter are sized correctly for what is actually coming out of the ground.
- Swap sediment cartridges on time. If your well system has a cartridge filter, a clogged one feels like a failing pump. Changing it on schedule keeps pressure up and protects the softener behind it.
- Drain seasonal spaces before deep cold. For a cabin or three-season porch, shut the supply, open the lowest drain and the faucets, and leave them open. Water left in the lines splits fittings during a cold snap.
- Keep a heat source near the pressure tank. Well tanks in unheated crawl spaces or pump houses can freeze. Insulation or a safe, approved heat source around the tank and switch keeps water flowing in January.
