Hide Well and Tank Equipment (Cedar Lattice Box)
A cedar-lattice screen can soften the view of well pressure tanks and related equipment without enclosing the wellhead. Plan it as a freestanding, ventilated, removable screen: first confirm local well rules, electrical clearances, equipment instructions, and freeze needs. Keep service routes open, protect drainage, and never rely on lattice alone to provide required airflow.
Do you prefer a clean, natural cedar look over seeing a pressure tank, exposed pipes, and controls from the patio? A lattice screen can help, but the goal is to hide the equipment from view, not hide it from the technician. I plan these screens around access, airflow, and local rules before choosing their height or style.
Planning: Identify Equipment, Local Rules, and Freeze Risk
Before you size a cedar screen, identify what it would surround and what must remain exposed. A well system may include a pressure tank, pump controls, treatment equipment, pipes, and electrical components. Their clearances and exposure needs can differ, so check each item rather than treating the entire area as one object.
Start with a site walk and a written list. Note the equipment’s make and model, power source, visible vents, drains, shutoffs, and the direction each component must move for repair or replacement. Find the manufacturer’s installation instructions; they are the first place to check for service space, cooling needs, and limits on enclosure.
Then check local well-construction rules and the adopted building and electrical codes. Well casing height, cap design, drainage, and setbacks vary by jurisdiction. Do not assume a typical dimension applies to your property. If you cannot confirm a requirement, ask the local health department or building official before building.
Map weather and site conditions
Freeze risk depends on local climate, equipment location, and the system’s design. A lattice screen is not insulation, and it should not interfere with an approved freeze-protection method. Consider wind-driven rain, snow depth, flood risk, and whether runoff flows toward the equipment.
Mark the wellhead separately from the tank area. The screen must not cover or enclose the casing, cap, vent, inspection point, or drainage path. Keep any required wellhead clearance open. A neat screen around the tank does not justify blocking access to the well itself.
Access and Clearances: Preserve Electrical Space and Service Routes
A working-space boundary is the clear area needed to inspect or work on certain electrical equipment safely. Where NEC 110.26 applies, the screen, posts, doors, and stored items must stay outside that space. Its dimensions depend on the equipment and conditions, so verify the adopted code edition and applicable requirements.
For equipment within the section’s scope, NEC 110.26(A)(1) generally calls for at least 30 inches of width, or the equipment’s width if greater. Under many conditions, working depth is at least 3 feet, but the required depth varies with the voltage-to-ground and the conditions described in the applicable table. The general height is at least 6 feet 6 inches, or the equipment height if greater. Confirm the exact rule locally; do not use these figures as a universal layout.
Keep a clear route to each shutoff, control, gauge, drain, and service panel. The tank itself may need room to be adjusted or removed. No single service-clearance dimension fits every installation, so use the equipment instructions. If they do not state a removal path, make the screen panels removable and leave every serviceable part reachable.
Do not treat a hinged gate as adequate access if it swings into electrical working space or cannot open fully. Mark clearances on the ground before setting posts. If the planned screen conflicts with a required space or access route, change the layout rather than narrowing the clearance.
Execution: Build a Removable, Ground-Clear Cedar Screen
A freestanding screen is a separate frame that supports lattice without relying on the well casing, pipes, or equipment for strength. Build it on a stable, drained base, keep the cedar away from soil, and make at least one panel easy to remove. This lets the screen serve as visual cover without becoming a permanent barrier to service.
Set out the screen before digging
- Mark the equipment and access areas. Use the manufacturer’s instructions and local rules to mark service space, electrical working space, and the path for removing equipment. Also mark vents, drains, and cooling openings that must remain clear.
- Check for buried utilities. Before digging or driving stakes, use the local utility-location service and follow its process. Do not assume shallow hand work is safe near buried lines.
- Choose the screen footprint. Place it beyond all required clearances. Leave enough room for the removable panel to come away from the equipment, not merely enough room for a person to stand nearby.
- Build a stable frame. Use a drained base and secure the frame for local wind and snow conditions. Do not fasten it to the casing, pipes, tank, or control equipment.
- Attach open lattice. Keep the sides open enough to avoid creating a tight box, but remember that visible openings do not prove airflow is adequate. Do not block a motor’s cooling path or an equipment vent.
- Test removal and access. Remove the panel and confirm that a person can reach service points and that equipment can follow its expected removal path.
Cedar can be used as a screen material, but its placement matters as much as its appearance. Keep wood clear of soil and standing water. IRC R317.1, where adopted and applicable, generally requires wood siding, sheathing, and wall framing to be at least 6 inches above earth. A freestanding lattice screen is not automatically siding, but if it functions as wall cladding, ask the local official how the rule applies.
Comparison: Choose a Screen Layout That Fits the Equipment
The best layout depends on what needs screening and what must stay open. A simple side screen may hide a tank from a patio while leaving the top and service side clear. A multi-sided screen can block more views, but it needs careful checking for access, airflow, and working space.
| Layout | Useful when | Main checks before building |
|---|---|---|
| One-sided lattice panel | The equipment is visible from one main viewing area | Keep the service side and route open |
| Two- or three-sided screen | Several views need screening | Confirm airflow, panel removal, and electrical clearance on every side |
| Removable panel system | Equipment needs regular inspection or a clear removal route | Make latches accessible and test panel removal |
| Screen placed around the wellhead | Not appropriate as a way to conceal the wellhead | Do not cover the casing, cap, vent, inspection point, drainage, or required clearance |
A screen that hides less but preserves clear access is usually a better plan than a tight enclosure that looks complete. Compare the proposed footprint with the manufacturer’s service instructions before cutting lumber.
Verification: Check Airflow, Wellhead Access, and Maintenance
Airflow is the movement of air needed to keep equipment within its intended operating conditions. There is no universal CFM value for a passive screen around a well pressure tank. Follow the pump, tank, control, and treatment-equipment instructions, and do not enclose equipment that requires an open installation.
A lattice pattern may look open while still restricting airflow if it sits too close to a motor or vent. It can also trap heat, or hold damp air in cold weather. If the instructions prohibit an enclosure or do not make the installation conditions clear, consult the manufacturer or a qualified well contractor before proceeding.
Use this final inspection
- Confirm the casing, cap, vent, inspection access, and drainage remain visible and unobstructed.
- Check that the screen sits outside electrical working space required for applicable equipment.
- Open and remove each access panel; verify service points and the equipment removal route.
- Look for blocked vents, motor cooling paths, drains, or shutoffs.
- Check that the frame is stable, drains well, and does not touch the equipment or piping.
- Recheck clearances after adding plants, mulch, snow barriers, or stored items.
Repeat the inspection after landscaping changes and before seasonal weather shifts. A shrub that grows into a service route can undo a careful screen layout.
Planning Examples: Apply the Rules to Common Setups
These examples are planning scenarios, not reports of specific installations. They show how I would apply the same checks to different equipment arrangements. Actual requirements depend on the equipment, local rules, and site conditions.
Tank beside a house wall: I would first verify whether the pressure tank or controls need open installation and record their service clearances. A single lattice panel might screen the tank from the yard while leaving its controls and service side accessible. I would not attach the frame to the wall or use the panel to reduce required electrical working space.
Tank with exposed controls and a removal route: I would map the route needed to remove the tank before setting posts. A removable panel on that side can help, provided it can be taken away without tools where practical and does not swing into required electrical space. I would test removal before installing lattice on the other sides.
Equipment near a wellhead: I would treat the wellhead as a separate, protected area and screen only the tank or related equipment where local rules allow. The screen would not cover the casing or cap, block drainage, or interfere with inspection. If the available footprint cannot preserve those conditions, I would use a smaller screen or leave the area exposed.
Conclusion: Keep the Screen Removable and the System Reachable
A cedar-lattice screen works best when it is planned as a visual screen, not a sealed equipment box. Confirm local well rules, code requirements, and manufacturer instructions first. Then set the frame outside required clearances, preserve airflow and drainage, and make access panels easy to remove. Check the layout again after landscaping changes.
Frequently Asked Questions
Can I put a cedar lattice box around a well pressure tank?
Only if the equipment instructions and local rules allow it. Use a freestanding, open, removable screen, and preserve service access, airflow, and electrical working space.
Can I cover the well cap with lattice?
No. Do not cover or enclose the well casing, cap, vent, inspection point, drainage path, or any required clearance.
How much ventilation does a well tank enclosure need?
There is no universal CFM requirement for a passive enclosure. Follow the instructions for the pump, tank, controls, and treatment equipment.
How far should the screen be from electrical controls?
There is no single distance for every installation. Where NEC 110.26 applies, required working space depends on the equipment and conditions. Confirm the adopted edition and applicable measurements.
Does every well tank need 3 feet of electrical clearance?
No. The 3-foot figure is a general minimum under many conditions for equipment covered by NEC 110.26. The required depth varies, so check the applicable code table.
Can I attach the lattice frame to the well casing or pipes?
No. Use a separate, stable frame. Do not fasten the screen to the casing, piping, tank, or controls.
Can lattice replace the equipment’s required ventilation?
No. Lattice openings do not prove that airflow is adequate. Do not block vents or motor cooling paths, and do not enclose equipment that requires an open installation.
How do I keep cedar off the ground?
Use a stable, drained base that holds the wood clear of soil and standing water. If the assembly functions as wall cladding, ask the local official how applicable clearance rules apply.
Should the screen have a removable panel?
Yes, where practical. A removable panel makes inspection and service easier, but it must not obstruct required working space or access routes.
Do wellhead height and setback rules apply everywhere?
No. Casing height, cap requirements, drainage, and setbacks vary by jurisdiction. Confirm the rules with the local health department or building official.
