Why pipes burst in Midwest City homes
Most burst pipes here come from one of three causes. Freezing is the obvious one: a hard freeze turns water to ice inside a line, the expansion splits it, and it leaks when it thaws. Age is the second. Census Bureau survey data shows about 4 in 10 Midwest City homes were built before 1970, and galvanized steel from that era corrodes from the inside until a thinned wall gives way. Early copper develops pinholes and weak joints of its own.
Pressure is the third, and it is easy to overlook. The city's 2025 Water Master Plan found maximum pressures across most of the distribution system range from 40 to 100 psi. The International Plumbing Code that Midwest City enforces calls for a pressure-reducing valve when pressure inside a building exceeds 80 psi. A house running high pressure on old pipe is a burst waiting for a reason.
Emergency water leak repair after freezing
After a hard freeze, a pipe can split and stay quiet until it thaws. On February 16, 2021, Oklahoma City, right next door to Midwest City, reached minus 14°F, its second-lowest temperature on record according to the Oklahoma Climatological Survey. Cold like that splits lines in places that rarely freeze: exterior walls, garage ceilings and attics over additions. When the thaw comes, check for wet drywall, dripping ceilings and a meter that runs with everything off.
Once the water is stopped and the pipe is fixed, we explain what led to the burst and how to keep it from happening again, whether that means insulation, sealing a draft or moving a line into heated space. Our main burst pipe repair page covers repairs and prevention in more depth.
If a pipe bursts right now
Shut off the main water valve first, then turn off power at the breaker to any area where water is near outlets or fixtures. Move valuables out of the way and call us. If the water is coming from the street or the meter box, that is a city line, and Midwest City lists 405-739-1383 for after-hours water emergencies.
Open a faucet at the lowest point of the house after the main is closed, so the water left in the pipes drains out there instead of through the break. For more on Midwest City's water system and older housing, see our Midwest City plumbing page.
