Salt chlorinator decommissioning is one of the first steps on pool removal day, and it is not a job for the homeowner. A licensed electrician must isolate the chlorinator circuit before any water is touched or equipment is removed. Understanding what happens to each piece of pool equipment during a full pool removal helps you prepare the site and avoid surprises on the invoice.
Quick answer (BLUF)
Before demolition starts, a licensed electrician disconnects the salt chlorinator and pump circuit at the switchboard, and a licensed plumber caps off any gas heater supply. The demolition crew then removes salvageable equipment, including pumps, filters and solar panels, before breaking begins. Some items have resale or scrap value; others go to the skip. Check our pool removal hidden costs checklist to see which decommissioning items can add to your base quote.
Salt chlorinators: cell, board and salt disposal
A salt chlorinator system has three main components: the electrolytic cell in the plumbing line, the control board (usually mounted on a fence post or wall near the equipment bay), and the salt dissolved in the pool water itself.
The cell is a piece of consumable equipment with limited resale value once it is a few years old. Most cells are removed by the electrician or plumber during the disconnect and disposed of with the general site waste. If the cell is relatively new and in good condition, ask the contractor whether it can be cleaned and retained for sale or personal use.
The control board contains low-voltage electronics. Boards from common Australian brands have a modest second-hand market. If yours is under five years old, it is worth asking the crew to set it aside rather than tipping it. Older boards go to e-waste collection or skip.
The salt in the pool water is handled as part of the drainage process. Salt concentration in a typical pool ranges from around 3,500 to 5,000 ppm. This needs to be considered when you plan the discharge method. Our pool water disposal cost and how to drain a pool safely and legally guides cover the discharge options and the concentration limits that apply.
Pool pumps, filters and pressure vessels
The pool pump is the most likely item to have resale value. A quality variable-speed pump that is fewer than three years old can attract a reasonable second-hand price. The demolition crew will remove it from the plumbing before breaking begins. If you want to keep it or sell it yourself, tell the contractor at the quoting stage.
Sand filters and media cartridge filters are usually scrapped. Sand is heavy, of low value and often contaminated with pool chemicals; it goes to the tip. Glass media has slightly more value. Filter tanks made of fibreglass or polyethylene are bulky to dispose of and often end up as skip waste.
Pressure vessels from old chlorine dosing systems or CO2 systems need to be de-pressurised and checked before disposal. This is a licensed-plumber or licensed-gasfitter task, not a DIY one. Our pool plumbing and electrical decommissioning guide covers the plumbing cap-off steps in more detail.
Gas and electric pool heaters
Gas pool heaters require a licensed gasfitter to isolate the supply and cap the gas line at the meter or at the branch point, depending on the installation. This step must be completed before demolition and before any other work in the equipment bay. Do not assume the demolition contractor carries a gas licence. Confirm it at quote stage.
Electric pool heaters and heat pumps contain refrigerant. Under Australian law, refrigerant handling requires an Australian Refrigeration Council heat pump handling licence (ARC tick). An unlicensed person must not vent or recover refrigerant. Confirm your contractor has the relevant ARC authorisation if they are handling a heat pump heater.
The heat exchanger and cabinet from a gas or electric heater have minimal resale value once removed. They typically go to scrap or tip.
Rooftop solar heating loops
Solar pool heating panels on the roof are a separate decommission task from the rest of the pool equipment. The solar loop contains pool water, which must be drained back through the pool before the panels are removed. This is usually timed alongside the main pool drain.
Panel removal requires work at roof height, which is a safety-regulated activity under NSW Work Health and Safety rules. Confirm the contractor or a subcontractor is carrying out the roof work safely with fall protection in place. Solar panels can be set aside for sale or donation to a pool owner, or disposed of with general demolition waste.
Pipe runs from the roof back to the pool equipment bay are cut and capped. On older installations the pipes may be running under the slab or through wall cavities, adding labour to fully trace and remove them.

Recycling vs skip: what has salvage value
Not all pool equipment is rubbish. The table below gives a general guide to what commonly has salvage value and what typically goes to skip or tip. All assessments depend on age and condition.
| Equipment item | Typical salvage or resale value | Typical disposal path |
|---|---|---|
| Variable-speed pump (under 3 yrs) | Moderate | Retain or sell |
| Single-speed pump (older) | Low | Scrap or skip |
| Salt chlorinator cell (new) | Low to moderate | Retain or sell |
| Salt chlorinator board (new) | Low to moderate | Retain or sell |
| Sand filter tank | Nil | Skip or tip |
| Rooftop solar panels (working) | Low to moderate | Donate or sell |
| Gas heater/heat pump | Nil to low | Scrap metal |
| Pool lighting (LED) | Low | Retain or sell |
| Polished coping or tiles | Low to moderate | See tile recycling guide |

What a licensed electrician and plumber do
Before demolition can begin, two licensed trades visit the site. This is not optional; it is required by law.
A licensed electrician isolates the pool circuit at the switchboard, removes the chlorinator board and pump, disconnects any pool lighting circuits and ensures the switchboard is safe for the demolition crew to work near energised circuits elsewhere in the property. For licensing information, check NSW Fair Trading electrical licensing requirements.
A licensed plumber isolates and caps the water supply to the pool, disconnects chemical dosing lines, caps any gas supply to a pool heater and removes the pump from the plumbing manifold. On a partial pool removal fill-in, the plumber also confirms that drainage to the sewer or stormwater from the pool area is properly disconnected or redirected.
After both trades have signed off, the demolition crew takes over. Our what happens on pool demolition day guide walks through the rest of the sequence.

FAQs
Do I need to arrange the electrician myself, or does the pool removal contractor do it?
This varies by contractor. Some pool removal companies include a licensed electrician as part of their quote; others ask the homeowner to arrange the electrical disconnect separately. Confirm at quoting stage which trades are included and ask for the relevant licence numbers. This is one of the items flagged in our pool removal hidden costs checklist.
Can I remove the pool pump myself before the crew arrives?
Not from the electrical circuit. Removing the pump from its plumbing connections can be done by a homeowner, but disconnecting the electrical supply to the pump and chlorinator requires a licensed electrician. Never attempt to disconnect pool electrical equipment at the switchboard yourself. Check NSW Fair Trading electrical licensing if you are unsure what qualifications are required.
What happens to the salt left in the pool water?
The pool water, including its salt content, is discharged either to sewer under a Hunter Water trade-waste consent or tanked away. Salt concentration at typical pool levels is not dangerous, but it needs to be managed within the discharge limits that apply at your site. See our how to drain a pool safely and legally guide for the full process.
Can I keep my pool heater for another purpose?
A gas pool heater is purpose-built for heating pool water and is not generally adaptable to other uses. A heat pump heater is similarly purpose-built. If the unit is in working order and of a popular brand, it may have resale value to another pool owner. Ask the contractor to set it aside at disassembly. A gasfitter or refrigeration mechanic can assess whether it is worth refurbishing before disposal.
Is there anything on the site I should move before the crew arrives?
Yes. Remove vehicles, pot plants, outdoor furniture and any portable items from the equipment bay and the path between the pool and the street. Ensure the pool area is accessible and that any gate locks are open. Our how to prepare your property for pool removal day guide has a full site-preparation checklist.
