A licensed plumber should remake joints and replace transitions, and a licensed gas fitter should do any gas tubing repair.

Customers put it like this

  • Water is dripping from a pipe
  • A fitting under the sink is leaking
  • The new joint is weeping
  • The plastic pipe cracked near the heater
Check it step by stepPrepare this job in ForeBot

Stop first if

  • Water is spraying or flooding the buildingClose the closest valve or the main only if it can be done without risk. Otherwise leave the area and call for help.
  • Water has reached a panel, outlets or powered equipmentStay out of the water. Call the electric utility or a licensed electrician before anyone goes in.
  • You smell gas, or corrugated gas tubing is punctured, nailed or badly crushedDo not bend the tubing or pry at it. Leave the building and call the gas utility from outside.

Check it step by step

Answer what you can see or measure. Each answer sets causes aside, and the check offers the one cheap reading that best separates the rest. Nothing is saved, and no account is needed.

Start the check
01

Ask on the call

6

Homeowner? These are the questions a good technician will ask you. Having the answers ready makes the first visit count.

  1. Is it spraying, or a slow drip?
  2. Do you know where the main shutoff is, and does it close?
  3. Is the water near outlets, a panel or appliances?
  4. What is the pipe made of, if you can tell?
  5. Was any work done nearby, such as spray foam, paint or pest treatment?
  6. Did it start after someone fastened shelves, trim or drywall there?

Bring

  • Flashlight
  • Moisture meter

  • Go/no-go gauge for crimp rings
  • Pipe and fittings, matched after the material is identified

Check on site

  1. Confirm the line is shut off and pressure relieved before touching the joint.
  2. Read what is printed on each pipe length and stamped on each fitting in that run.
  3. On metal, find which side is corroding. Note any copper-to-steel joint and the fitting used there.
  4. On plastic, map the damage against nearby products, lights, flues and other heat.
  5. On a mechanical joint, check insertion depth, the cut, burrs and scoring. Check crimp tools with the maker's gauge.
  6. Look for hangers, studs or wire ties touching copper, and note if those spots stay wet.

Keep on the record

  • Photos of the leak point and the print line
  • Which material is damaged, and what touches it
  • Joint type and the insertion mark as found
  • Which valve stopped the water, and if it closed fully
