A sewer camera spends most of its life in storage, and that is where much of the damage happens: a head put away damp fogs and corrodes, a battery stored flat dies, a rod coiled too tight sets a bend, a card left in a monitor in a hot van fails. Storing the reel properly costs ten minutes after the job and nothing else, and it decides whether the reel works when it is next needed.
Quick answer: clean and dry everything before the case closes; store the head with its protective cap on, O-rings clean and lightly greased, or detached if the maker recommends it; coil the rod on the reel without forcing it and leave the lock off or lightly on; remove the card and back up the footage; store the battery at a partial charge, around half, in a cool dry place and top it up every couple of months; keep the case indoors, out of a hot van and above freezing; and run the pre-use check before the first job of the season.
Dry first
Nothing goes in the case wet. The spring coils, the connector between rod and head, and the reel drum hold water that will sit against metal and seals for weeks. Air-dry after cleaning and wipe the connector before it is reassembled or capped. Cleaning after a sewage job ends where storage begins.
The head
Fit the protective cap or guard if one came with the reel. Inspect the O-rings, clean the mating faces and apply a thin film of the lubricant the manual specifies. Some makers recommend detaching the head for long storage to protect the connector; others want it left on to keep the connector sealed. Follow the manual. O-rings and seals covers the lubricant question and when to replace a head what long neglect does.
The lens
Clean and dry, with the cap on. A lens stored against foam that has absorbed grit is scratched by the next vibration in a van. Lens scratches often start in the case.
The rod and reel
Wind the rod onto the drum evenly without forcing coils tighter than the drum’s radius, and leave the reel lock off or just engaged so the rod is not held under strain for months. A fibreglass rod stored tightly coiled takes a set that makes it harder to push and more likely to kink. Check for kinks before storage; a kinked rod stored under tension gets worse. Push cable kinks covers the mechanism.
The monitor
Power off fully, not standby. Remove the card and copy the footage to a computer and a backup; cards left in a monitor through heat and cold fail, and footage from a job is evidence. Wipe the screen. Protect the connectors with their covers. SD card care covers the card.
The battery
Lithium batteries store best at a partial charge, around half, in a cool dry place; stored full they age faster, stored flat they may not recover. For a built-in battery, run the monitor down to about half before putting it away and top it up every two or three months. For a removable battery, store it out of the monitor. Never store a battery in a van through summer heat or winter frost. Battery care and single vs dual battery systems cover the detail.
The locator
If the kit has a receiver, remove or partially charge its battery as for the monitor, cap the antenna and store it in its own padding. A receiver with alkaline cells should have them removed for a season. Locator maintenance covers it.
The case
Dry the case and its foam before closing. Store the case indoors in a dry room, off a concrete floor, out of direct sun and above freezing. A van is a storage location only between jobs on the same day; a reel that lives in a van through a winter has a battery, a screen and seals that have been frozen and baked for months.
Accessories
Skids, guides, spare O-rings, the charger and the manual go in the case in their own pockets, so the next job does not start with a search. A spare set of O-rings and a tube of the right lubricant live in the case permanently.
Seasonal storage
For a reel put away for a season, do everything above and set a reminder to charge the battery every two months and to run the pre-use check a week before the first job, so a problem is found with time to fix it. The ten-minute pre-use test is the check, and winter precautions covers bringing a cold reel back to work.
What goes wrong in storage
Fogged lenses and corroded connectors from damp. Dead batteries from a flat or a hot van. Set rods from tight coiling under lock. Failed cards and lost footage. Mould in foam. Cracked screens from a case dropped off a shelf. Every one of them is prevented by the ten minutes above.
Common questions
Should I store a sewer camera battery fully charged?
No. Around half charge, cool and dry, topped up every couple of months, is what lithium cells prefer.
Can I leave the sewer camera in my van?
Between jobs on the same day, yes. Overnight in heat or frost, and for any longer period, no.
Should the camera head stay on the rod in storage?
Follow the manual. Some makers want it on to seal the connector; others want it off to protect it. Either way, cap and dry it.
