When Should You Change Bathroom Supply Lines

10/8/2018 (Permalink)

Water damage due to supply line in Las Vegas,NV

The frequency with which bathroom supply lines will need to be replaced depends on the material and condition of the lines. Prevent a bathroom leak by keeping an eye out for signs of supply line damage.

Supply Line Materials

Solid lines are ideal for long runs, whereas flexible lines are suitable for short runs. Common solid supply line materials include

  • Copper
  • Chromed copper
  • CPVC

Copper can be up to three times as expensive as plastic lines. You can save money by using flexible materials, such as

  • Braided stainless steel
  • Flexible copper
  • PEX

Keep in mind that building codes in some regions prevent the use of braided plastic supply lines.

Supply Line Durability

Solid copper supply lines can last for decades. Flexible lines may not be as long-lasting, but they are more affordable and can be easier to use. Most plastic lines are covered by five- to eight-year warranties. Steel braided lines have warranties upward of five years, and some of the most reputable brands may offer a lifetime warranty.

Causes of Supply Line Damage

Several common causes of damage include

  • Broken lines
  • Corroded braided metal hoses
  • Stress corrosion and separation of brass barbed fittings
  • Broken plastic coupling nuts

Any type of damage may result in a bathroom leak. Replace the line and fittings to ensure that a new supply line is not prone to leaking.

Replacing Supply Lines

Measure the distance from the inlet valve to the fixture and add four inches to the length of a flexible line. Most faucets have a 1/2" female pipe connector and most toilets have a 7/8" ballcock connector at the fixture. Both tend to have either a 1/2" or 3/8" female compressor or sweat connector at the shut-off valve.

Replace lines when you notice supply line damage such as corrosion or leaking. If you experience a severe supply line leak, contact a plumber and water damage restoration experts in Las Vegas, NV.
