What Inland Marine Insurance Does Not Cover on Septic Gear
A cascade of seven steps, each stepping down from the one before. It starts with the broad grant: direct physical loss to septic gear on the move. The schedule narrows it first, because a machine missing from the schedule was never covered property. Then missing property comes out, where a machine disappears with no physical evidence of what happened. Then loss traced to design defects, faulty workmanship, materials or maintenance comes out, and wear and tear generally points the same way. Then machinery breakdown often comes out, since a pump or engine that fails on its own is generally treated as a separate line. What remains is paid at the policy’s valuation, and actual cash value can be less than replacement cost. At the bottom is what the floater answers, with trucks and trailers generally left to commercial auto. Your own policy wording controls. No figures are shown.
Inland marine insurance, through an equipment floater, generally covers direct physical loss to septic gear that moves between jobs. Its exclusions and terms set the limits: policies read by the Eastern District of Michigan (2016) and the Appellate Court of Illinois (2012) left out missing property and paid actual cash value, not replacement cost.
What inland marine insurance is for
Inland marine is generally property insurance for business property that moves. California’s regulator puts it plainly: “Inland marine is a specialized type of property insurance”. Virginia describes the line as written primarily for property in transit, and North Carolina says it will generally “cover property that is mobile or in transit”.
For a septic business, the version that matters is the contractors equipment floater. California names “equipment floaters (i.e., contractors equipment)” among the common inland marine types, and Virginia’s commercial guide lists contractors’ equipment among its uses. On this site that coverage is described on the contractors equipment page.
The name confuses people. California’s guide notes that inland marine does not cover boating transportation, which belongs to ocean marine insurance instead. For a crew that moves an excavator on a trailer and a vacuum pump on a truck, the relevant idea is mobility, not water.
How an equipment floater is built
Most inland marine policies start broad and then narrow through exclusions. North Carolina says most inland marine policies cover physical loss, and it credits the line with introducing the all-risks idea, “now generally referred to as direct physical loss”. California lists standard perils such as fire, theft, collision and overturn.
One floater reviewed by the Supreme Court of Vermont in 2019 defined covered causes as direct physical loss, minus the causes its exclusions listed. That shape is the reason a post about what a floater does not cover is really a post about exclusions. Generally, whatever the exclusions take away, the broad grant does not give back.
It is also why the schedule matters. Some floaters list machines one by one. If a piece of gear is missing from the schedule, the exclusions never come into play because the machine was not covered property in the first place. The equipment lists in septic pumping equipment from vacuum pump to hose reel and equipment needed to install a septic system by machine are a useful checklist to compare against your own schedule.
Missing equipment and inventory shortages
A floater may not pay when a machine simply disappears and nobody can show what happened to it. The U.S. District Court for the Eastern District of Michigan in 2016 reviewed a contractor’s-equipment policy with a missing property exclusion that reached “unexplained or mysterious disappearance of covered property”.
The same exclusion reached a “shortage of property discovered on taking inventory”. The machine in that case was a scheduled item listed on the policy, and it had been stored away from regular use when it disappeared. The Eastern District of Michigan (2016) applied the exclusion where there was “no physical evidence to show what happened”.
Theft with evidence of a break-in may be treated differently from a machine that simply cannot be found, since the exclusion in that case turned on the absence of physical evidence. Reporting a loss promptly and preserving whatever evidence exists may matter as much as the policy language itself.
For a septic business, that has a practical edge. Equipment that sits in a back lot between seasons, or a trailer left at a job over a long weekend, can go missing without anyone seeing it leave. Keeping records of where gear is stored and when it was last seen may help separate a theft from an unexplained loss, though the wording of your own floater controls how a given loss is treated.
Defects, faulty workmanship and poor maintenance
Many inland marine forms exclude loss that traces back to how the equipment was designed, built or kept up. The U.S. District Court for the Eastern District of Pennsylvania in 2012 reviewed an inland marine policy that excluded claims arising from a design defect, and also excluded “faulty or defective workmanship, materials, maintenance or construction”.
That same court put the burden of proving an exclusion on the insurer, and it described exclusions as strictly construed against the insurer. Those principles may help an insured in a close case, but they generally do not change what the exclusion says. A failed weld on a pump mount, or a hose fitting that let go because it was never replaced, can put a loss in the argument over whether maintenance or a covered cause did the damage.
Many equipment forms also carry wording about wear and tear and gradual deterioration. Where it appears, it generally points the same way: the floater is written for sudden physical loss, not for the ordinary aging of a machine that works hard every day.
Breakdown of engines and pumps
Machinery breakdown is generally treated as its own line of insurance rather than something a property form absorbs. California describes boiler and machinery insurance as addressing losses that result from the malfunction of boilers and machinery. It also says “most commercial property policies exclude losses from boilers and machinery”.
That passage may not speak to floaters directly, since it concerns property policies. Whether a given floater reaches an engine or pump that fails on its own generally depends on its own wording. For a pumping crew whose day depends on a vacuum pump, it is worth asking the question directly.
One way to read the difference is by cause. A pump damaged when a trailer overturns on the way to a job fits the kind of peril California lists, collision and overturn among them. A pump that fails because its internal parts malfunctioned looks more like the breakdown line California describes separately. The two can look alike in the yard and may read very differently on a claim. The tools and pumps that matter most are listed in septic tank tools a pumping and inspection crew carries.
Real-World Scenario: A pumping crew parks a trailer-mounted pump at the yard for the winter and moves on to other jobs. In the spring, the owner goes to hitch it up and the pump is gone. There is no broken lock, no tire track and no witness, and nobody can say when it left. The floater’s exclusion for unexplained disappearance becomes the center of the claim, and the owner wishes the yard had kept a sign-out log.
Valuation can pay less than replacement cost
A floater that pays a loss may still pay less than it costs to buy the machine new, because valuation is set by the policy. The Appellate Court of Illinois in 2012 reviewed a claim in which a crane owner sought replacement cost and the policy paid actual cash value. The valuation terms sat in the policy’s contractors equipment coinsurance and valuation provision.
The Appellate Court of Illinois (2012) found the policy unambiguous on actual cash value, which it described as “a lesser sum than replacement cost”. Virginia’s guide separates replacement cost from actual cash value in property settlements, and North Carolina lists actual cash value, replacement and agreed value as possible bases. Which one your floater uses is set on the policy, and it is worth knowing before a loss, especially on older excavators and trucks that still do the job every day.
Rented, borrowed and collapsed property
Rented and borrowed gear may or may not be reached, depending on the wording. The floater reviewed by the Supreme Court of Vermont in 2019 reached “rented equipment or tools, while they are in your care”, and it reached borrowed property only where the insured had accepted responsibility, in the policy’s words property “for which you have accepted responsibility”.
The same policy excluded collapse except as its own additional coverage provided, and the Supreme Court of Vermont (2019) held that collapse coverage applied only to business personal property. It also paid debris removal only if the expense was reported in writing within a set window. For an installer who rents a larger excavator for a big drainfield, those details decide whether the rental is protected, and whether a cleanup cost gets paid at all. Rented gear is often part of septic installation work, so it is worth checking the rental wording before the machine arrives.
Trucks and trailers usually belong to a different policy
Vehicles that travel the road are generally a commercial auto question, not a floater question, although the line between the two can be technical. The Supreme Court of Ohio in 2014 reviewed a liability policy that defined an auto to exclude mobile equipment, and tied that definition to vehicles subject to a motor vehicle insurance law.
Its prong for pumps reached only vehicles, in its words, “not self-propelled and are maintained primarily to provide mobility” for that equipment. The Supreme Court of Ohio (2014) held the policy’s mobile equipment definition did not include trailers. That was a liability policy, not a floater, but it shows that the auto and mobile-equipment line exists and is drawn by wording. For the vacuum truck and pump truck themselves, the place to look is commercial auto, and gear kept at a fixed shop may sit under commercial property instead.
The practical step is to line up the floater, the auto policy and the property policy side by side for septic pumping and septic repair gear, and to see where each machine lands. If you want that done against your own forms, request a quote. Your own policy wording controls, and the forms in use differ from one insurer to the next.
Questions septic owners ask about this
What does inland marine insurance not cover?
It depends on the wording, but the exclusions quoted in the decisions in this post include property that goes missing with no physical evidence of what happened, shortages found only at inventory, and loss from design defects or faulty workmanship, materials or maintenance. California’s regulator also treats machinery breakdown as its own line. Valuation can limit a payment too, since some forms pay actual cash value rather than replacement cost.
What does an inland marine policy cover?
Inland marine is generally a form of property insurance for business property that moves or is in transit. North Carolina’s regulator says most inland marine policies cover physical loss, and California lists perils such as fire, theft, collision and overturn. For a septic business, the equipment floater is the common version, and it may reach excavators, pumps and tools as they travel between jobs, subject to its own exclusions.
How does inland marine insurance work?
Most inland marine forms start from a broad promise to pay for direct physical loss to covered property and then take away specific causes through listed exclusions. What is left after those exclusions is what the policy answers. Equipment may be listed item by item on a schedule, and the policy states how a loss will be valued. Reading the exclusions and the valuation clause together generally gives the clearest picture.
Does inland marine insurance cover contractors equipment?
Often, yes, in the sense that contractors equipment floaters are among the most common types of inland marine coverage. California’s consumer guide names them, and Virginia’s commercial guide lists contractors’ equipment among inland marine uses. Whether a given machine is included, and on what terms, depends on the schedule and wording of your own floater, so it is worth checking that every piece of gear you rely on actually appears there.
Does my equipment policy pay if a machine just goes missing from the yard?
Possibly not. A federal court in Michigan in 2016 applied a floater exclusion for unexplained or mysterious disappearance where there was no physical evidence of what happened to a scheduled machine stored away from regular use. Theft with evidence may be treated differently from a machine that simply cannot be found. Keeping records of where equipment is stored, and reporting promptly, can matter, and your own wording controls.
Does an equipment floater pay when an engine or pump breaks down on its own?
Often it will not, though the answer turns on the wording. California’s regulator treats machinery breakdown as a separate line, boiler and machinery insurance, and says most commercial property policies exclude those losses. Whether a particular floater may reach a breakdown of a pump or engine generally depends on its own exclusions, so it is worth asking before a vacuum pump fails mid-season rather than after.
