How to do a basic Plastic Tank Cleaning safety check and quick fixes

Quick answer (read this first)

• Regularly inspect your plastic water tank for cracks, leaks, and algae growth.
• Check all inlet and outlet pipes for blockages, loose connections, or drips.
• Ensure the tank lid is securely fastened to prevent contamination.
• Maintain good ventilation around the tank to prevent moisture buildup.
• Clean exterior debris and observe water quality for any changes.

Safety first

• Work only in well-lit areas, preferably during daylight hours.
• Use a stable, sturdy ladder and never climb on unstable tank surfaces.
• Wear protective gloves and eye protection, especially when handling water from inside the tank or using cleaning agents.
• Ensure adequate ventilation if using any chemicals or working in confined spaces.
• Never attempt electrical repairs on pumps or wiring. Call a qualified electrician.
• Avoid entering tanks or working alone on elevated tanks.

Tools you may need

• Flashlight or headlamp
• Rubber gloves and safety glasses
• Soft-bristle brush, sponge, or clean cloth
• Adjustable wrench (for minor pipe connections)
• Small bucket or container
• Waterproof duct tape or epoxy repair kit (for temporary small leak fixes)

Step-by-step

Step 1

Safety First: Before starting, ensure you have adequate lighting and a stable ladder if working at height. Wear gloves.

Step 2

Exterior Visual Inspection: Carefully inspect the entire outer surface of the plastic tank for any cracks, bulges, discolouration, or signs of algae growth.

Step 3

Check Tank Lid Security: Ensure the tank lid is tightly sealed and free of debris. A loose lid can lead to contamination from dust, insects, and other pollutants.

Step 4

Inspect Pipes and Connections: Examine all inlet, outlet, and overflow pipes. Look for visible leaks, loose fittings, corrosion, or any signs of blockage. Gently check if valves are operating smoothly.

Step 5

Observe Water Level Indicator (if present): Verify that any water level indicator is functioning freely and not stuck, providing an accurate reading.

Step 6

Listen for Unusual Sounds: Pay attention to any strange noises from the tank or the connected water pump. Grinding or sputtering sounds might indicate blockages or mechanical issues.

Step 7

Address Minor External Leaks (Quick Fix): For very small, non-structural cracks or pinholes on the exterior, clean the area thoroughly and apply a temporary fix using waterproof duct tape or a specialized plastic repair epoxy kit. Remember, this is a short-term solution.

Step 8

Clean Tank Exterior: Using a soft brush or cloth and plain water, wipe down the exterior of the tank to remove dust, dirt, and minor algae buildup. Avoid harsh chemicals.

Step 9

Ensure Proper Ventilation: Check that there is sufficient space and airflow around the tank to prevent excessive heat retention and inhibit mould or algae growth in the surrounding area.

Common mistakes

• Ignoring minor leaks or drips, which can quickly escalate into larger, more damaging problems.
• Using abrasive brushes or harsh chemical cleaners that can scratch, weaken, or damage the plastic tank material.
• Attempting advanced repairs (e.g., major crack sealing, pump repair) without the necessary expertise or proper safety equipment.
• Leaving the tank lid unsecured or damaged, directly leading to water contamination from pests, dust, and debris.
• Neglecting routine visual inspections, allowing small, easily preventable issues to develop into significant and costly problems.

When to call a professional

• When you discover large cracks, significant bulges, or any structural damage to the plastic tank itself.
• If leaks persist or reappear after attempting temporary quick fixes.
• For any problems involving the water pump, electrical connections, or wiring – these require a qualified professional.
• If the water consistently has an unusual colour, odour, or taste, even after external checks, indicating potential internal contamination.
• When you need a comprehensive internal cleaning, disinfection, or descaling of the tank.
• If you are ever unsure about the safety of a repair, the source of a problem, or feel uncomfortable performing any part of the maintenance.
