Towson Residential Housing Stock & Plumbing Challenges
Towson serves as the county seat of Baltimore County, showcasing mature residential neighborhoods such as West Towson, Stoneleigh, Rodgers Forge, and Wiltondale. Featuring historic brick colonials, rowhomes, and mid-century split-levels, Towson residences frequently maintain legacy plumbing systems comprising galvanized iron supply lines, centrifugally cast-iron soil stacks, and Type M copper piping.
During Baltimore winter cold snaps, uninsulated exterior wall runs in historic homes freeze, generating hydraulic pressures exceeding 2,500 PSI that cause longitudinal pipe fissures upon thawing. Furthermore, aging cast-iron soil stacks experience internal sulfur-gas corrosion, developing hairline cracks that discharge sewer gas and wastewater into wall cavities.
