Lancaster’s Old Homes & Wells

Take a typical Lancaster city row house on East Orange Street, built around 1900. The owner - call her Sarah - loves the old hardwood floors and tall windows. One morning, the shower pressure is a trickle and the cold tap runs reddish brown for a few seconds. The culprit is decades old plumbing. Many older houses still contain outdated piping that constricts water flow and causes low pressure. Galvanized steel piping was common and it does not age well - internal corrosion and mineral scale narrow the effective diameter over time. Cleaning aerators can give a temporary boost, but replacement with copper or PEX is the long term fix ^[3].

Another challenge is lead plumbing. Many homes were built before lead was recognized as a hazard. The city treats water to be non corrosive and it leaves the plant lead free, but lead service lines or interior components can still leach lead at the tap. In recent years, Lancaster Public Works identified about 550 confirmed lead service lines and roughly 3,200 suspected out of about 48,000 total - small in percentage, important for any single family ^[4][5].

Sarah did a simple DIY check in the basement. The incoming pipe looked dull gray. A scratch revealed shiny silver - a telltale sign of lead - and a refrigerator magnet would not stick, which also rules out steel. That combination points to a lead service line. She scheduled a professional replacement and followed interim guidance like flushing water after long stagnation and using a filter certified for lead reduction ^[6][7].

Galvanized sections can coexist with lead service lines. Corroded galvanized can even trap lead particles like a sponge, releasing them later. Replacing old lines improves both water quality and pressure, and it stabilizes hot water delivery in daily use.

Winter is tough on under insulated older homes. Pipes routed along exterior walls or through crawl spaces can freeze. Insulation, heat tape at vulnerable sections, and simple day to day habits like opening sink bases on bitter nights help prevent freeze ups and burst damage ^[9].

Outside the city, many homes draw from private wells. The Millers near Lititz use a drilled well about 200 feet deep. As regional agriculture intensified, neighbors reported rising nitrates. A test kit showed their well approaching the EPA limit of 10 mg/L. Nitrates typically come from fertilizers, manure, and septic seepage that reach the aquifer; risk is highest for infants because nitrates can cause methemoglobinemia - often called blue baby syndrome ^[10][11][12].

In May 2025, a local water authority in Lancaster County issued a public nitrate warning at 10.8 mg/L - just over the federal limit - and advised parents not to use tap water for infant formula until resolved. For private well owners, annual testing is essential. A typical recommended panel includes total coliform bacteria, nitrates, total dissolved solids, and pH. Testing after floods or any taste or odor changes is also wise. Local state certified labs make this straightforward and affordable ^[13][14].

When nitrates are elevated, point of use reverse osmosis at the kitchen sink is an effective mitigation. Some households use anion exchange for nitrate removal. If levels stay high, deeper wells or connection to a community supply may be considered.

Hardness is another Lancaster constant. Mineral scale reduces heater efficiency and clogs fixtures. A softener that swaps calcium and magnesium for sodium improves lather, reduces spots, and protects appliances. Annual water heater flushing helps clear sediment and preserve performance ^[15].

Submersible well pumps work hard. Sediment and iron can abrade components and mineral scale can form on the pump itself. Typical life is roughly 10 to 15 years depending on conditions. Low water cutoff protection and a little stored drinking water provide resilience during surprise outages ^[16].
