How to Clean Grey Water Tank Sensors

Maintaining your RV's grey water tank is crucial for a pleasant and problem-free camping experience. A malfunctioning sensor can lead to inaccurate readings, leaving you unsure of how full your tank is and potentially leading to unpleasant overflows. This guide will walk you through how to effectively clean your grey water tank sensors to ensure accurate readings and avoid costly repairs.

Understanding Grey Water Tank Sensors

Before we dive into cleaning, let's understand what these sensors do. Grey water tank sensors are typically float-based or electronic sensors. Float-based sensors use a simple float that rises and falls with the water level, sending a signal to your control panel. Electronic sensors use conductivity to measure the water level. Both types can become clogged with debris, leading to inaccurate readings.

Common Causes of Sensor Malfunction

Several factors can contribute to inaccurate grey water tank sensor readings:

1. Debris Buildup:

This is the most common culprit. Soap scum, hair, grease, and other organic matter can accumulate on the sensor, interfering with its ability to accurately measure the water level.

2. Mineral Deposits:

Hard water can leave mineral deposits on the sensors, impacting their functionality. This is especially prevalent in areas with high mineral content in their water supply.

3. Biofilm Formation:

Over time, a slimy biofilm can develop on the sensor, further hindering its performance. This is a common issue if the grey water tank isn't regularly cleaned and flushed.

4. Physical Damage:

Although less common, the sensor itself might be damaged. This could be due to accidental impact or corrosion.

Cleaning Your Grey Water Tank Sensors: A Step-by-Step Guide

The best approach depends on the type of sensor you have. However, several methods can be employed for both types:

1. Visual Inspection:

Before you begin any cleaning, locate your grey water tank sensors. This usually involves accessing the tank through a dedicated access panel. Inspect the sensors closely for any visible debris or buildup. This will guide your cleaning approach.

2. The Simple Rinse:

For both types of sensors, a thorough rinsing with clean water can often dislodge loose debris. Use a garden hose or a pressure washer (low-pressure setting) to flush the sensors and surrounding area. Ensure the water drains properly after rinsing.

3. Vinegar Solution (For Mild Buildup):

A vinegar solution is a gentle yet effective way to dissolve mineral deposits and soap scum. Mix equal parts white vinegar and water. Pour the solution over the sensors, allowing it to sit for several hours or even overnight. Rinse thoroughly afterward. Never use bleach or harsh chemicals, as these can damage the sensors and your tank.

4. Baking Soda Paste (For Stubborn Buildup):

For more stubborn buildup, create a paste of baking soda and water. Apply this paste directly to the sensor, gently scrubbing with a soft brush. Allow it to sit for a while before rinsing thoroughly.

5. Advanced Cleaning (If Necessary):

If the above methods fail, consider using a specialized cleaning solution designed for RV grey water tanks. Follow the manufacturer's instructions carefully.

Preventing Future Sensor Problems

Regular maintenance is key to preventing future sensor issues.

• Regularly Flush Your Grey Water Tank: This helps prevent debris buildup and keeps your tank cleaner.
• Use Biodegradable Products: Biodegradable soaps and cleaning products are gentler on your tank and sensors.
• Avoid Pouring Grease Down the Drain: Grease can solidify and clog your sensors.
• Monitor Your Tank Levels Regularly: This allows you to catch potential problems early.

By following these steps and implementing preventative measures, you can ensure your grey water tank sensors remain clean and provide accurate readings for many years to come. Remember to always consult your RV's owner's manual for specific instructions and recommendations.
