Flat Baffled tanks

Flat Baffled Tanks — FAQs

1. What are flat baffled tanks?

Flat baffled tanks are rectangular water storage tanks made from heavy-duty polyethylene that include internal baffles (walls or barriers) to reduce water movement when the tank is carried or transported.

2. Why are they “baffled”?

The internal baffles restrict the water from sloshing around inside the tank during transit — this improves vehicle stability and makes transport safer, especially when the tank is partly full.

3. How do flat tanks differ from upright tanks?

Flat tanks sit horizontally and are ideal where you want low height and easy space fitting, whereas upright tanks stand vertically. Flat tanks are often preferred in vans and pickups when you want to use the space above the tank for storage or equipment.

4. What sizes are available?

Flat baffled tanks come in a range of capacities — from 125 L up to 1000 L — so you can choose the tank size that best matches your water needs and vehicle space.

5. What material are these tanks made from?

They are made from clear heavy-duty polyethylene, which is strong, durable and resistant to corrosion and most water conditions, making them suitable for long-term use.

6. What are flat baffled tanks used for?

They’re commonly used for:

• Mobile window cleaning rigs and pure water systems

• Car valeting and pressure washing water supply

• Water transport in vans, pickups or bowsers

• Camping, events and other mobile water needs

7. How do I connect a pump or hose to it?

The tanks come with BSP outlet fittings (e.g., ¾″ or 1″ BSP depending on size) at the base, so you can easily connect a pump, tap or hose — making them ready for use with your water systems.

8. Can I see the water level?

Many flat tanks are made from semi-translucent polyethylene, so you can see the approximate water level without opening the lid.

9. Are these tanks suitable for drinking/potable water?

Flat baffled tanks can be used for potable water storage if made from food-grade or potable-safe materials, but you should check the specific product details on The Cleaning Warehouse site if you intend to store drinking water.

10. How do I choose the right size?

Choose based on:

• How much water you need to transport or store

• Available vehicle or storage space

• How often you refill or use water for your application
  For example, smaller tanks (125–250 L) are great for shorter jobs, while larger tanks (500–1000 L) suit longer days or bigger teams.
