Water Service Lines

The Water Delivery System (WDS) is comprised of two subsystems including:


Water Service Lines (WSL)


  • The system of pipes, fitting, valves etc. that connect the water main with a house and deliver potable water from the water supplier


Water Supply System (WSS)


  • The system of pipes, fittings, valves, etc. that connects plumbing fixtures and appliance with the WSLs and supply hot and cold potable water to faucets, showers, toilets, and other plumbing fixtures or appliances

Water Service Line Water - Leak Causes


The most common causes of water line ruptures or leaks in our area include:



  • Makes pipes brittle
  • Brittle pipes have a tendency to  crack or break


  • Acidic soil and water destroys the exterior metal of the pipe
  • Process eventually causes corrosion, rust, and leaks/breaks

Aging Water Pipes

  • Water pipes loose strength and durability over time and become brittle
  • Brittleness combined with high water pressure increases the likelihood of leaks, fractures, and breaks

Physical Damage

  • Water pipes accidentally damaged by construction work or renovations create leaks, fractures, or breaks

Excessively High Water Pressure

  • Pressure inside the pipe is greater than the strength of the pipe
  • This condition causes pipes to leak or fracture

Poor Workmanship

  • Improperly installed joints and high water pressure
  • Cause leaks, ruptures, and breaks in the water line

Polybutylene Tubing

  • The presence of chlorine compounds in water will cause deterioration of the internal chemical structure of polybutylene piping and the associated acetyl fittings
  • The deterioration, or chemical corrosion, leads to perforations of the pipes and fitting and their subsequent leaking or bursting.


Repair or Replace Decision Criteria


When to replace or when to repair a water line is a frequently asked question.  Our recommendations are based on the following:


Service Line




  • The useful life of a typical water line = ~ 50 years
  • Replace – when water service line is over 50 years old
  • Repair – when water service line is less than 50 years old and not lead or galvanize steel and if repair is legal and makes economic sense

Code Restrictions

  • Many municipalities restrict repairs of  lead or galvanized steel water service lines regardless of their condition or age
  • Replace due to code requirements
  • Only legal alternative


Cost Comparison

  • If service line repair is equal to or greater than 50% of cost of a copper or PEX replacement
  • Replace


Water Service Line Materials


GPS Plumbing recommends:


  • Copper
  • PEX


As the pipping materials for a water service line replacement – both are code complaint and are modern materials designed for long years of service.
