How to Find the Right Weatherproof Pump Enclosure

Before diving into how to find the right weatherproof pump enclosure for you, it’s great to explore some reasons why you need one:

custom pump system needs enclosureProtection from Rust and Corrosion

Rain, wind, and snow can all cause rust and corrosion. If the device becomes corroded, it can potentially reduce the life of the pump. You can help ensure the pump lasts longer with the right weatherproof pump enclosure.

Protects Motor from Heat & Cold

The most expensive parts of your pump are located in the device’s motor. This part of the pump is the most vulnerable to heat and cold, affecting the device’s longevity. Repairs to this area are often very costly, and most issues can be prevented with a proper weatherproof pump enclosure. Pumps also put off a large amount of heat that can melt and warp a plastic enclosure, so choosing one made of aluminum is ideal.

Helps Lessen Noise Pollution

Pumps can be very noisy and, in a residential setting, may cause complaints from residents and visitors. A weatherproof enclosure, such as Safe-T-Cover’s insulated aluminum enclosures, has sound dampening insulation. It’s important to note that fake plastic rocks, fiberglass enclosures and metal cages offer little to no sound insulation.

Different Types of Weatherproof Pump Enclosures

When it comes to types of weatherproof pump enclosures, there are at least three options you can choose. Each differ on the material used, and each has pros and cons. Knowing them is vital to determine what type of enclosure you need.

Aluminum Enclosures

This weatherproof pump enclosure is industrial-style with sturdy construction and is highly durable. Aluminum enclosures are designed to offer the best UV and corrosion resistance. Thanks to aluminum’s strength and versatility, this enclosure is popular with small and larger projects alike.

Fiberglass Enclosures

Fiberglass enclosures are often chosen for smaller devices because they are lightweight. Reinforced fiberglass is easy to install and affordable, and works for devices up to four inches, which a single person can install by themselves. This means you can install the enclosure independently without paying for labor. However, fiberglass enclosures are prone to damage, including from mowing equipment , and susceptible to the elements. So while carrying a low cost up front, servicing, repairing, or even replacing a fiberglass enclosure may end up costing more in the long run.

Plastic Enclosures

Plastic enclosures are made of polyethylene and are often found for smaller pumps. Much like their fiberglass cousins, plastic enclosures are prone to damage, fading and ultimately fail to protect pumps. Additionally, heat can affect plastic, warping it and causing it to come into contact with pump parts. Simply put, plastic is not a great long term solution.

Metal Cages

The least common type of enclosure for pumps, these cages offer very little protection, other than from vandals. They offer no protection from the elements and are highly discouraged from being used.

What Factors to Consider When Buying a Weatherproof Pump Enclosure

Here are helpful factors to consider when looking for an enclosure. With these as a guide, you should be able to pick an enclosure that will serve you best in protecting your pump.

Superior Protection

You need the enclosure to protect your pump, so your choice must offer superior protection. It should have insulation that will not delaminate or sag, meaning it has a strong chemical bond. Similarly, it should be made from a sturdy material that can withstand extreme temperatures.

ASSE 1060 Certification

This means the cover passes the requirements for drainage capacity, structural strength, equipment access, material construction, and functional design. An ASSE 1060 certification gives you peace of mind knowing the enclosure passes industry standards.

Resistance to Scratch and Corrosion

Some pump enclosures are designed to be weatherproof while also having corrosion and scratch-resistant finish. A pump enclosure with this finish is an excellent choice because it will last for years, and still look new despite being exposed to the elements.

Ease of Access

The best pump enclosure should make it easy to access the device it protects. When looking for a weatherproof pump cover, make sure that you or a professional can access the backflow preventer without any problem. 

Quick Installation

This factor is to your advantage – you want to be able to install without much trouble in which case, you want an enclosure with a simple design. Look for one you can quickly assemble without complicated parts and complex instructions.

Some Common Questions and Answers for Choosing a Weatherproof Pump Enclosure

What Size of Weatherproof Pump Enclosure Should You Use?

The size you need for a weatherproof pump enclosure depends on the device you will use it for. You should check the size of your pump first, then the recommended clearance between the device and enclosure. It’s important to note that most spec sheets provide this information. If it’s not available, contact the pump manufacturer to obtain this information.

Which Class of Weatherproof Pump Enclosure Do You Need?

The answer to this depends on your location. First, find out your location’s lowest average winter temperature and compare with the ASSE Class ratings mentioned below:

  • Class I (Heated): Freeze Protection Enclosures – Maintains external temperature as low as -30-degree Fahrenheit and an internal temperature of 40-degree Fahrenheit.
  • Class II (Insulated Non-Heated): Freeze Retardant Enclosures – Installed in locations with 33-degree Fahrenheit minimum temperature.
  • Class III (Uninsulated Non-Heated): Non-Freeze Protection Enclosures – Provides system security for components if freezing temperatures are not considered.

What Codes and Specifications Do You Need To Follow?

You need to follow three code types – ASSE standard, NFPA, and ASPE. The ASSE 1060 Standard gives details on fluid conveying components. NFPA 13 addresses the permission to protect pipes from freezing through insulated coverings and other means. Lastly, ASPE, or the American Society of Plumbing Engineers, provides further guidelines on your enclosure’s safety.

What Happens if There Is a Power Failure?

If a power failure happens, the heater will stop working and the only thing protecting your pump is the insulation within the enclosure. That’s why it is imperative to choose a weatherproof pump enclosure that has sufficient insulation to help provide extra protection. Safe-T-Cover uses standard 1.5” R-9 insulation in the wall panels and 3” R-18 insulation in the roof panel. This helps provide ultimate protection, even in the case of a power failure.
