What Is Plumbers’ Scrap and Why Is It Valuable?

In the plumbing industry, there’s an often-overlooked stream of income and sustainability: scrap metal recovery. Known within the trades as plumbers' scrap, this term refers to the various metal components discarded during plumbing repairs, replacements, and installations. These materials—ranging from copper piping to brass fittings—carry considerable market value and, when recycled properly, can generate significant returns for plumbers, businesses, and the environment.

Let’s explore what plumbers’ scrap includes, why it’s so valuable, and how professionals can take full advantage of it.

🔎 What Counts as Plumbers’ Scrap?

Plumbers' scrap includes all the metal parts removed during regular plumbing work, especially from older infrastructure. Over time, plumbing systems wear out, become obsolete, or require upgrading. When this happens, parts like copper pipes, brass valves, and stainless steel components are replaced—and the old materials often end up as waste.

• Brass Fittings – Taps, joints, compression fittings, and shut-off valves made of brass are heavy and valuable due to their zinc-copper alloy content.

• Stainless Steel – Found in braided hoses, water heater casings, and some high-end fittings.

• Lead – Especially common in older homes, lead piping and solder can be toxic but is still a scrapable metal (handled with proper safety measures).

• Iron or Steel Components – These are ferrous metals, typically less valuable than non-ferrous ones but still worth collecting.

💰 Why Is Plumbers’ Scrap So Valuable?

1. High Commodity Prices

It is widely used in electronics, renewable energy systems, and infrastructure. As of mid-2025, copper prices can reach upwards of $9,000 to $10,000 AUD per tonne, while clean brass scrap may be worth $5,000 or more per tonne.

This means that even a few kilograms of sorted, clean scrap can translate into hundreds of dollars—especially for plumbers who collect scrap consistently over time.

2. Regular, Reliable Source

Unlike industries that deal in occasional scrap surpluses, plumbers work on residential and commercial properties every day. Every pipe replacement, fixture upgrade, or hot water system swap generates some amount of scrap metal. While an individual job may only yield a few kilos, over weeks and months, this builds into a reliable stream of valuable material.

For plumbing companies, scrap can become a modest but steady secondary income source—particularly when captured and sorted efficiently.

3. Ease of Separation and Collection

Another reason plumbers’ scrap is so appealing is that the materials are relatively easy to identify and separate:

• Copper has a distinct reddish color and is soft but sturdy.

• Brass has a yellow-gold hue and is heavier than copper.

• Stainless steel is silver-gray and resists rusting.

This visibility allows plumbers to sort materials on-site, maximizing value when delivering to scrap yards. Clean, sorted metal is worth significantly more than mixed or contaminated scrap, so the extra care pays off.

4. Recycling Infrastructure and Trade Perks

In many regions, especially in cities like Perth, there’s a growing infrastructure to support tradespeople with scrap metal collection:

• Free bins or IBCs for job sites

• Scheduled pickups to save time and transport

• Immediate weighing and payment

• Competitive rates for trade clients

Companies like Go Recycle, Runabout Metals, and QB Copper Recycling in Perth, WA, all offer services tailored to plumbers. By working with trusted local scrap yards, tradespeople can simplify collection while earning fair prices.

5. Environmental Sustainability

Every kilogram of recycled copper:

• Saves up to 85–90% of the energy needed to extract and process virgin ore.

• Reduces the demand for open-pit mining.

• Keeps toxic materials like lead or corroded metal out of landfill.

For companies conscious about environmental responsibility—or seeking to meet green building requirements—scrap recycling offers a low-effort, high-impact way to reduce waste.

🧰 Tips to Maximize Scrap Value

Plumbers who are new to scrap recycling—or looking to improve their returns—can benefit from a few simple strategies:

✔️ Sort Materials by Type

Always separate copper from brass, and both from ferrous metals (steel or iron). Clean, pure materials fetch higher prices than mixed batches.

✔️ Remove Contaminants

Take time to cut off soldered joints, remove plastic coverings, or unscrew fittings from piping. This helps turn "dirty" scrap into "clean" scrap, which is worth more per kilo.

✔️ Use a Dedicated Collection Bin

On larger jobs, ask your scrap yard for a free bin. Keep it in your truck or site shed and empty it when full. Some recyclers even offer same-day pickup.

✔️ Keep Track of Prices

Scrap prices fluctuate. Check with your local yard or online price boards to time your drop-offs for the best return.

✔️ Document for Tax or Records

Keep receipts from scrap sales—particularly if you're a business. This income may be reportable, but can also offset disposal costs or count toward green building certifications.

📍 Local Recycling Options (Perth Example)

In Perth and other major Australian cities, multiple recyclers actively work with plumbers. Here are a few examples:

Many of these businesses require a valid photo ID and proof of address for compliance with WA’s second-hand dealer regulations. Some may offer bank transfer only due to scrap cash bans in certain regions.

✅ Final Thoughts

Plumbers' scrap is a hidden but powerful asset in the plumbing trade. What might seem like waste—cut-off pipe, old taps, corroded fittings—can become a valuable, renewable resource when properly handled. With consistent collection, material sorting, and smart partnerships with scrap yards, plumbers can enjoy extra income, reduce environmental impact, and strengthen their business operations.
