Polybutylene Pipe Replacement
In Severna Park, MD —
The Hidden Problem
Polybutylene pipe (PB pipe) was installed in Severna Park homes built between 1978 and 1995. It is flexible grey or blue plastic that deteriorates at fittings when exposed to chlorinated municipal water. Fitchet Plumbing provides non-invasive diagnostic assessments and complete code-compliant PEX repiping throughout Severna Park (ZIP 21146) and Anne Arundel County. MD License #70218.
Does Your Severna Park Home Have Polybutylene Pipe?
Check your supply lines before scheduling service. Open the cabinet under any bathroom or kitchen sink and check the pipes extending from the wall or floor behind your shutoff valves (not the braided stainless steel fixture connectors). Polybutylene is grey or blue flexible plastic, distinctly separate from orange copper, threaded grey galvanized steel, or cream-colored CPVC. Look closely in bright light for “PB” or “PB2110” stamped on the pipe wall.
Where To Check In Your Home
Inspect the cold water inlet piping near your water heater, exposed basement ceiling joists, and unfinished crawlspaces. If grey plastic runs between floor framing, PB is present throughout the entire domestic supply system.
Severna Park Areas Most Affected
Homes built during the 1980s construction boom carry the highest concentration: Cypress Creek, the Benfield Road corridor, later phases of Chartwell, 1978–1985 sections of Severna Forest, and Amberley.
Why Does Polybutylene Fail — And Why Now?
Polybutylene was approved under historical building codes as an economical copper alternative. Failure occurs because oxidants like chlorine and chloramine in municipal water break down the polymer chains, resulting in microscopic fractures at stressed fittings.
Years 1–15: Initial Performance
The plastic maintains wall thickness and elasticity with no outer evidence of breakdown.
Years 15–25: Internal Micro-Cracking
Chlorine degradation begins internally at mechanical fittings, acetal inserts, and crimp rings while remaining hidden inside wall cavities.
Years 25–40+: Systematic Joint Failures
Fittings installed during the 1980s have reached terminal age. Minor seepages turn into wall cavity leaks, and because identical water flowed through all lines, one leak indicates adjacent fittings are failing.

Catching fitting breakdown early prevents structural water damage, flooring ruin, and mold growth inside wall framing:
Unexplained Ceiling Stains
Slow fitting seeps travel along joists and pool far from fixtures. Stains appearing on lower-level drywall mean water has been leaking for days.
Soft Spots In Flooring
Continuous low-volume joint drips saturate subflooring and baseboards along supply walls before moisture becomes visible on top of carpet or hardwood.
Elevated Water Utility Bills
A $40–$120 spike in monthly Anne Arundel County water charges without changes in household use points to active pipe seepage. Shut all faucets and monitor the meter dial.
Remodeling Discoveries
Opening bathroom or kitchen framing frequently uncovers dark mold and framing rot from long-term, slow-drip polybutylene crimp leaks.
Visible Grey Supply Lines
If your 1978–1995 home has grey plastic under the sink, that alone warrants review. Pre-failure assessment is vastly more affordable than mold remediation.
Neighboring Failures
Because homes in tracts like Cypress Creek were built simultaneously with identical batches of piping, a leak next door is a direct warning sign.
