Plumbers in Michigan

Two kinds of winter damage

Everyone understands the first kind. A pipe in an unheated space freezes, the water expands, the pipe splits, and when it thaws the house floods. A single burst supply line can release hundreds of gallons a day, which is why the main shutoff is the most important valve in a Michigan house and why knowing where it is matters more than any other piece of preparation.

The second kind is slower and does more damage in total. Michigan does not simply get cold, it crosses the freezing line repeatedly all winter, and the ground moves each time. Cast iron drain stacks develop hairline cracks that open a fraction with every cycle. Clay laterals shift and settle until a joint separates. Nothing dramatic happens on any given day, and then one spring a line that has worked for fifty years does not.

That is why homeowners so often say nothing changed. Nothing did. The process had been running for years and simply finished.

The melt is the test

Spring snowmelt puts more water into Michigan’s sewers in a short period than any other event of the year. Aging systems fill faster than they can move it, and the pressure relieves through the lowest connected opening nearby, which in a low-lying house is a basement floor drain.

There are two separate problems with the same symptom, and it is worth telling them apart. Sewage coming up through the floor drain is the sewer surcharging, and the answer is a backwater valve on the house drain. Clean groundwater seeping in around the floor and walls is hydrostatic pressure, and the answer is a working sump pump with a battery or water-powered backup. A house can have either, or both, and the fixes are different.

Both should be checked in autumn. The melt is not the time to find out the pump has seized or the discharge line is blocked with ice.

Lead, and the pipe you can check yourself

Detroit alone is estimated to have around eighty thousand lead service lines still connecting homes to the city mains, and utilities across the state are working through replacement programmes. Michigan’s rules on lead are among the strictest in the country, which is a direct consequence of what happened in Flint.

The homeowner’s part is simple. Find where the water enters the basement, ahead of the meter, and scratch the pipe with a coin. Lead is dull grey and soft, scratches to a bright silver, and is not magnetic. Copper scratches copper-coloured. Galvanized steel is threaded and a magnet sticks to it. Your utility can tell you what its inventory shows for your address, and a plumber can replace the portion on your side.

Galvanized on a clock, and hard water speeding it up

If a Michigan house still has galvanized steel supply lines, they are running out of time on a fairly predictable schedule. The zinc coating that protects the steel deteriorates over roughly forty to fifty years, the steel underneath begins to rust, and the rust narrows the bore from the inside. Pressure falls off upstairs first, and the first draw of the morning runs brown.

Michigan accelerates both ends of that. The temperature swings stress the pipe, and hard water across much of the state lays scale on top of the rust. Cleaning does nothing for a pipe in that condition; repiping the affected runs is what gives the pressure back. Every plumber we dispatch in Michigan holds the state licence and pulls the local permit for work that requires one.
