The 48089 ZIP code is the oldest part of Warren, MI. The brick bungalows and ranches here were built between 1940 and 1959, and the original steam boiler is still in many of those basements.
Homes in South Warren built before 1960 almost always have one pipe steam. A single pipe carries steam to each radiator and returns condensate back — air vents on each radiator are the most common failure point.
The cast iron boilers common in 48089 homes were installed by builders between 1940 and 1959. Many are Weil McLain Series 88 or Burnham V-Series units. Parts for both are still available.
South Warren homes from this era have settled over 60 to 80 years. Pipe pitch shifts as foundations move, and when condensate cannot drain back to the boiler, water hammer and cold radiators follow.
