Emergency Gas Leak Safety Protocol
-
1
Do NOT create any sparks or electrical contacts: Do not flip light switches, do not unplug appliances, do not use house phones, and do not strike matches or lighters. Any electrical arc can ignite accumulated natural gas or propane.
-
2
Evacuate the building immediately: Get all family members and pets out of the property at once, leaving doors open behind you to allow gas dissipation.
-
3
Shut off the exterior gas meter (if safely accessible): If you have an exterior gas shutoff valve and can reach it safely, turn the lever perpendicular to the pipe with an adjustable wrench.
-
4
Call 911 & emergency dispatch from outside: Once safely across the street, contact emergency services and our certified gas dispatch at (717) 296-0767 for immediate on-site response.
Certified Gas Plumbing & Complete Potable Water Modernization
Aging utility piping inside residential homes presents two significant risks: volatile fuel gas leaks that threaten physical safety, and corroded water lines that cause structural water damage, rust contamination, and chronic low pressure.
Hanover Plumbing Pros coordinates certified Master Plumbers across Hanover and York County qualified to test, repair, and replace natural gas and propane lines, as well as execute seamless whole-house repiping. Responding crews utilize high-sensitivity PPM electronic gas sniffers, digital manometers, and commercial PEX-A expansion tubing to modernize old systems safely and cleanly.
Service Technical Capabilities
Electronic Gas Leak Pinpointing
High-precision combustible gas sniffers and differential pressure manometers that identify microscopic joint leaks behind drywall and masonry.
Black Iron & CSST Piping
Code-certified installation of threaded schedule 40 black iron pipe and corrugated stainless steel tubing (CSST) for furnaces, stoves, and water heaters.
Whole-Home PEX-A Repiping
Clean, minimally invasive conversion from old corroded copper or brittle galvanized lines to freeze-resistant cross-linked PEX-A expansion piping.
Galvanized & Lead Elimination
Complete removal of hazardous lead solder and tuberculated galvanized iron pipe that restricts water volume and releases heavy rust sediment.
Hanover Historic Architecture & Gas Infrastructure
Many historic residential homes across Hanover Borough—especially in Downtown, Parkville, and along the McSherrystown corridor—were constructed in the late 19th and early 20th centuries. These properties often still contain original threaded black iron gas lines sealed with dried pipe dope that can crack under house settling, risking gas seepage.
Additionally, historic homes with original galvanized potable water lines suffer from internal mineral occlusion (tuberculation), where 1/2-inch pipes choke down to the diameter of a pencil. Modernizing to PEX-A restores crystal clear water and full household water pressure with minimal wall penetrations.
Transparent On-Site Written Pricing
Dispatched local technicians evaluate the existing piping infrastructure on-site and provide an itemized upfront written estimate before any work begins. Repiping and gas line repairs involve unique structural layouts, code compliance, and fixture counts; on-site inspection guarantees 100% price transparency with zero surprise fees.
