Copper Pinhole Leak Repiping in Tampa Bay

What a pinhole leak is

Copper has been a standard water supply pipe for decades, and it often lasts a long time. Some homes, though, develop pinhole leaks: tiny holes that eat through the pipe wall from the inside. A pinhole may start as a slow drip or a fine spray inside a wall, which is why the first sign is often a stain, a bubble in paint or a water bill that jumps.

Plumbers point to several possible causes, including water chemistry, how the pipe was installed and how fast water moves through it. You do not need to know the cause to make a decision. What matters is how often leaks happen and where.

Signs you have a copper problem

• A second or third leak within a year or two
• Leaks in different rooms or different runs of pipe
• Green or blue stains on pipes, fittings or fixtures
• Damp drywall, ceiling stains or warped baseboards
• A water bill that rises without a clear reason
• The sound of running water when everything is off

Repair or repipe?

A single leak in an otherwise healthy system is usually a repair. The math changes when leaks repeat. Each leak brings a plumber visit, wall and ceiling repair and sometimes flooring or mold work. Angi's Tampa guide lists water damage repair at about $1,380 to $6,380, drywall repair at about $300 to $930 and mold remediation at about $1,220 to $3,760, on top of the plumbing.

• One leak, pipe otherwise in good shape: repair and watch
• Two leaks in different places within a short time: get a repipe quote
• Three or more, or leaks in hard-to-reach places such as a slab: a repipe is often the better value

Replacing copper

Most homeowners who repipe after pinhole leaks choose PEX, which usually costs less and is not prone to the same kind of pinhole corrosion. Some choose new copper. Angi's Tampa guide lists PEX at about $1 to $2 per linear foot and copper at about $2 to $8 per linear foot for materials.

If a leak is under the slab, ask whether the plumber recommends rerouting that line overhead rather than breaking up the floor. Rerouting through the attic is common in Florida slab homes.

What to ask

• Can you show me where each past leak was, and what the pipe looks like inside?
• Is the whole system the same age and type of copper?
• Would you reroute any slab lines overhead?
• Is the permit, inspection and patching included?
• What warranty covers the pipe and your workmanship?

Insurance and leaks

Many homeowner policies treat repeated or gradual leaks differently from sudden ones. Read your policy and ask your agent before filing. If an insurer has asked about your plumbing, see repiping for insurance.
