3 Tips for Securing Enclosure Equipment and Accessories to Interior Walls

There are many situations where equipment and critical components must be mounted to the interior walls of a backflow enclosure. Common components include heaters, control panels, lighting, electrical receptacles, and other devices that support safe operation and easy testing access.

There are two primary reasons to use a wall mount approach inside a backflow enclosure.

First, floor space inside a backflow preventer enclosure is limited. When large equipment such as pumps, valves or piping assemblies occupy the slab, mounting smaller components on the wall free up valuable space and keeps the installation organized.

Second, elevating electrical hardware and sensitive components protects them from water exposure. In the event of a leaking valve, relief valve discharge or minor flooding, keeping components off the slab minimizes the risk of damage and improves long-term reliability.

When properly planned, wall-mounted enclosure parts enhance performance, simplify maintenance and help protect your overall investment.

Tip 1: Consider the Location of the Mounted Equipment

Before beginning installation, carefully evaluate where each component will be mounted inside the backflow enclosure.

For example, if you're protecting a booster pump that requires a control panel, that panel should be installed in a location that allows easy access through the door or removable panel. An operator should not have to climb over piping or reach behind equipment just to turn a system on or off.

Strategic placement also makes future replacement easier. If a panel needs to be serviced or swapped, accessible mounting reduces labor time and frustration.

The same principle applies to lighting. Mount fixtures where they provide complete illumination of the enclosure interior, but also ensure bulbs or fixtures can be replaced without disassembling major components. Accessibility is a critical feature of a well-designed enclosure.

Tip 2: Consider the Weight & Holes Needed

Not all enclosure parts weigh the same. While many components are relatively lightweight, some hardware and electrical assemblies can be heavier and require additional support.

When mounting components, carefully plan for weight and any required holes in the wall panel. Every penetration should be intentional and properly sealed. Unsealed holes can compromise insulation performance, reduce weather resistance and create pathways for moisture intrusion.

If penetrations are required for wiring or conduit, use approved fittings and sealants to maintain the enclosure’s security features. A clean installation with minimal wall penetrations improves long-term durability and protects sensitive components from snow, frost and vandalism.

Tip 3: Hang on Wood Studs or Unistrut

Before installation, confirm what the enclosure wall is constructed from and identify appropriate mounting points. Safe-T-Cover enclosures are manufactured with genuine redwood studs inside the wall panels. These redwood studs provide structural integrity and create secure attachment points for wall-mounted components.

For heavier hardware, always fasten directly into studs or approved structural members. If a stud is not available where needed, install a Unistrut channel system to create a reinforced mounting surface. Attach the Unistrut securely using machine screws, washers and bolts appropriate for the enclosure wall panel, as shown in the drawing.

Proper support prevents sagging, shifting or damage to enclosure parts over time.

Making the Most of Your Wall-Mounted Design in Backflow Enclosures

Using the interior walls of a backflow enclosure to mount components saves space and contributes to a safer, more efficient and more cost-effective installation.

Wall mounting:

• Maximizes usable floor space
• Improves access for maintenance and inspection
• Keeps electrical hardware away from potential water discharge
• Reduces the need for larger sizes enclosure

In many cases, thoughtful interior layout allows you to specify a more compact enclosure without sacrificing functionality. This can lower material costs while maintaining full protection for your equipment.

Why Aluminum Enclosures Are the Smart Choice for Backflow Preventers

A complete enclosure design considers how interior components are mounted, accessed and maintained for the life of the installation, but before you can think about the interior you need to consider the exterior.

When you choose an above-ground aluminum enclosure, you're making the best choice for a variety of reasons.
