You’re Sitting on More Money Than You Think!

As a plumber operating around Sydney — whether you’re doing bathroom renovations in the Eastern Suburbs, hot water replacements in the west, or maintenance runs through commercial buildings across the CBD — you’re generating valuable non-ferrous scrap metal every day.

A lot of it goes into the back of the ute, gets tossed into a skip bin, or eventually accumulates in the corner of the shed until it becomes someone else’s problem.

The thing is, that “waste” actually has monetary value. Copper pipe offcuts, old brass fittings, and even those corroded valves you pulled out of a ceiling cavity can all have scrap value.

The difference between a plumber who earns an extra few hundred dollars a month from scrap and one who throws it away often comes down to knowing what you’ve got, how to sort it, and where to take it.

This guide explains the non-ferrous metals plumbers commonly collect on the job, how to separate them, and how to get the best possible return when selling them.

Copper — Your Most Important Daily Byproduct

Copper is the bread and butter of plumbing scrap. You deal with it on almost every job, and it’s typically one of the highest-value non-ferrous metals at Sydney scrap yards.

Common Types of Copper That Plumbers Collect

Copper pipe offcuts — Each time you cut into existing pipework or install new runs, you’re left with offcuts. Even short lengths accumulate over a week. Both Type B (standard wall) and Type A (heavy wall) copper tube are highly valued.

Decommissioned copper pipe from replacements — When you replace old copper water lines during renovations or upgrades, they can generate significant lengths of scrap. Older homes throughout Sydney’s Inner West, North Shore, and Eastern Suburbs can contain substantial amounts of copper pipework.

Copper cylinders from hot water systems — Older electric and gas storage hot water units contain copper components, including cylinders and heat exchangers. When you replace an old Rheem or Dux system, those copper components are worth keeping for scrap.

Copper coils from hydronic systems — Older hydronic heating systems being taken out of service can contain copper coil heat exchangers. These are heavy and valuable.

Copper earth wire — Bare copper earthing cable removed during plumbing-related work can also have scrap value. Even short lengths of 6 mm² and 10 mm² earth wire are worth hanging onto.

Ways to Maximise Your Copper Return

• Keep it clean — Copper pipe free of solder, fittings, and insulation can qualify for a higher grade. Clean, bright copper is generally the most valuable.
• Remove brass fittings — Don’t leave compression fittings or solder joints on your copper pipe where practical. Cut them off. The copper can be graded separately, while the brass fittings have their own value.
• Sort by condition — Keep bright, clean copper in one pile, and oxidised, tarnished, or soldered copper in another. Mixing grades can affect the value of the overall load.
• Don’t smash or crush it — Some plumbers stomp pipe flat to save space. This can make it more difficult to grade visually and may occasionally result in a lower offer. Keep it as-is where possible.

Brass: The Overlooked High-Value Metal

Brass is an alloy of copper and zinc, and it’s everywhere in plumbing. Many plumbers don’t realise exactly how much brass they throw away or that it can command a strong price per kilogram at scrap yards.

Where Plumbers Find Brass

Taps and mixers — Older taps and mixers can contain significant amounts of brass beneath the chrome plating. When you’re ripping out old bathroom or kitchen tapware during a renovation, keep it. Even contemporary mixers can contain brass components.

Brass compression fittings — Olives, nuts, couplings, elbows, and tees can all contain brass. They’re small individually, but a plumber doing regular work can accumulate kilograms of scrap recyclable brass over the course of a month.

Gate valves, ball valves, and check valves — Old isolation valves are often made from brass and can be recovered from water mains, hot water units, and commercial risers. The larger ones, such as 40 mm and 50 mm valves, can be surprisingly heavy.

Brass hose fittings and connectors — Garden tap bodies, hose cock assemblies, and backflow prevention devices can all contain significant amounts of brass.

Cistern components — Older toilet cistern inlet and outlet components were often made from brass. These can add up during bathroom renovations in older Sydney homes.

Fire hydrant and sprinkler fittings — If you do commercial or fire services work, brass fittings from hydrant systems can be common and valuable.

Why Sorting Your Brass Is Worth It

• Separate clean brass from chrome-plated brass — Some yards may pay slightly less for heavily chrome-plated items because the chrome adds non-brass weight.
• Remove rubber, plastic, and steel parts — Pull out washers, O-rings, steel screws, and handles where practical. Cleaner brass can achieve a better grade.
• Don’t mix brass with copper — They are different metals with different grades and values. Keep them in separate containers.
• Gunmetal and red brass — Older valves and fittings can be made from gunmetal or red brass. These materials can still have value, so don’t throw them away simply because they look different.

Lead: Heavy, Valuable, and Frequently Neglected

Lead is heavy, soft, and often more valuable than plumbers realise. Because it is less commonly used in new installations, recovered lead from older plumbing and building work can be an important scrap material.

Where Plumbers Find Lead

Lead flashing — Roof plumbers and general plumbers working on older properties can find lead flashing around penetrations, chimneys, and parapet walls. When replacing it with modern alternatives, the old lead can be valuable scrap.

Lead pipe — Lead pipe can still be found in some older Sydney properties. When you replace lead water services with copper or PE, keep the old pipe separate for recycling.

Lead caulking from cast iron joints — Older drainage systems used lead and oakum to seal cast iron hub-and-spigot joints. This lead can be recovered during drainage upgrades.

Lead-based solder — Older plumbing work used lead-based solder on copper joints. While it cannot easily be separated from the pipe, heavily soldered copper can still have scrap value.

Sheet lead from shower bases — Some older waterproofing methods used sheet lead under tiles in wet areas. Bathroom demolitions can occasionally uncover this.

Handling Lead Safely

• Wear gloves when handling lead, especially old lead pipe or flashing with surface oxidation.
• Don’t cut or sand lead in confined spaces — Lead dust can be hazardous.
• Store it separately from other metals in a sturdy container. Lead is heavy and can puncture bags.
• Wash your hands thoroughly after handling lead and before eating or drinking.

Other Non-Ferrous Metals Plumbers Encounter

Beyond the big three, plumbers regularly encounter:

Stainless steel — Flexible hoses, commercial fixtures, press-fit piping systems, and some newer valves. Stainless grades vary, including 304 and 316, and both can have scrap value.

Aluminium — Older hot water system casings, some pipe lagging, and certain commercial plumbing fixtures can contain scrap aluminium.

Zinc — Galvanised pipe is made from steel coated in zinc. While the pipe itself is ferrous, it is still worth separating from your non-ferrous pile so it does not contaminate your copper and brass.

Electric motors from pumps — Circulation pumps, pressure pumps, and hot water booster pumps contain copper windings inside. Some yards buy these whole as “electric motors” at a set grade.

Setting Up a Simple Sorting System in Your Ute or Shed

You don’t need anything fancy. Here’s a simple system that works for many Sydney plumbers:

In the Ute

• One heavy-duty bucket or crate for copper pipe
• One smaller container for brass fittings
• A sturdy bag or box for lead — keep it contained because it’s heavy

In the Shed or Workshop

• Separate 44-gallon drums or large bins labelled COPPER, BRASS, LEAD, and MIXED/OTHER
• A monthly or fortnightly routine to drop the material off at the yard

The trick is to keep the system simple enough that you actually use it, rather than letting everything collect into one giant, tangled mess that takes hours to sort later.

How Often Should You Sell?

This really depends on your workload, but here’s a general guide:

• Solo plumber doing residential work — Monthly drop-offs can usually accumulate enough material to make the trip worthwhile.
• Small team (2–4 plumbers) — Fortnightly runs can generate respectable returns, particularly if you’re undertaking renovations.
• Commercial plumbing teams — Weekly or even twice-weekly runs can make sense if you’re stripping out risers, replacing plant room equipment, or carrying out major refurbishment work.

The more consistent you are, the less it becomes an occasional side bonus and the more it can become a genuine income stream.
