Pump Covers 101: How to Protect Your Rainwater System from Damage and Noise

When most people invest in a quality rainwater tank and pump system, they think about water savings, sustainability, and maybe even a lush garden. But there’s one crucial detail they often overlook — and it’s surprisingly loud. Your water tank pump needs a cover.
Not just for aesthetic reasons (though they do tidy things up), but for protection, performance, and peace and quiet. Whether you’re new to rainwater systems or just sick of the pump’s 6am groaning every time the toilet flushes — this guide is for you. Let’s dive into the benefits of pump covers, why they’re a must-have, how to choose the right one, and how The Water Tank Factory can help.

1. Protect Your Investment
Your pump is the heart of your rainwater system — and pumps aren’t cheap. A good-quality unit can cost hundreds of dollars, so protecting it from the elements is just common sense.
A pump cover shields against:

• UV rays, which cause plastic and rubber components to degrade.
• Heavy rain and hail, which can cause corrosion or water damage.
• Leaves, dust and debris, which can clog up ventilation and reduce efficiency.

2. Reduce Noise (and Keep the Neighbours Happy)
If your pump’s installed near a bedroom, laundry, or close to a fence line, you already know how startling it can be. Pump covers are designed to muffle the sound — some by up to 75%!
This is especially important if your system kicks in automatically or you’re using it during the early morning or late at night.

3. Discourage Theft or Tampering
Believe it or not, water pumps are occasionally targeted by opportunistic thieves — particularly in rural or semi-rural properties. A discreet, lockable pump cover can:

• Help hide your system from view.
• Add a layer of security by limiting access.
• Prevent children or animals from tampering with it.

At The Water Tank Factory, we stock tough, UV-stabilised poly pump covers designed for Australian conditions. Here’s what to consider and features to look out for:

• Material UV-stabilised polyethylene is best for long-term outdoor exposure. It won’t crack, rust, or fade.
• Ventilation: Proper airflow prevents your pump from overheating and helps extend its lifespan.
• Size & Fit Measure your pump carefully (length, width, height) before purchasing. The Water Tank Factory’s pump covers suit a range of common pump models.
• Access Panels: some covers include hinged access for easy servicing. Ideal if your pump requires regular pressure checks.

• Condensation
• Wind-driven rain
• Pest intrusion
• UV from side-angle sunlight

A cover adds peace of mind and helps maintain optimal performance and longevity.

Installing a water pump cover is easy — usually a DIY job. Here’s how to do it right:
1. Clear the area: Remove any overgrown grass or weeds to allow ventilation and access.
2. Level the ground: A flat base (gravel or pavers) prevents water pooling and provides stability.
3. Position the cover: Ensure vents aren’t obstructed and the pump sits centred.
4. Check your access: Make sure you can still reach valves, switches, and the pressure gauge.
5. Secure the cover: Depending on the model, secure with ground pegs, bricks, or bolts.

Pro tip: If your cover doesn’t come with built-in vents, consider drilling small holes at the rear to allow warm air to escape.
