Printable, postable, and built to survive a summer of rotating guests: if your Brainerd Lakes Area cabin sees rental turnover, family visits, or a steady stream of weekend company, this is the list to tape up in the guest bathroom.
Why guest cabins are especially at risk
Guests don’t know your system the way you do — they don’t know if you’re on a Gull Lake mound system with a sensitive lift pump, or a tight Crosslake lot running a holding tank that fills faster than they’d expect. A little guidance up front prevents the single most common cause of an avoidable service call: something that should have gone in the trash going down the toilet instead.
Never flush these
- “Flushable” wipes — despite the label, they don’t break down like toilet paper and are one of the most common causes of clogs and pump damage
- Paper towels and tissues — sturdier than toilet paper, and they don’t disintegrate the same way
- Feminine hygiene products
- Dental floss
- Cotton balls, cotton swabs, and makeup wipes
- Cigarette butts
- Diapers or wipes of any kind
- Cooking grease or oil — not flushed exactly, but pouring it down any drain causes the same downstream problems
- Medications — harmful to the system’s bacteria and to lake water quality if it reaches the drainfield or mound
The simple rule to share with guests
If it isn’t human waste or toilet paper, it doesn’t go in the toilet — full stop. This one rule, posted somewhere guests will actually see it, prevents the majority of flush-related service calls across the region’s cabin rentals and guest bathrooms.
Why this matters more on a mound or holding tank system
A standard system has some tolerance for an occasional mistake; a mound system’s pump and distribution lines are more sensitive to anything that isn’t supposed to be there, and a holding tank simply fills faster if it’s absorbing solid waste it wasn’t designed for. If you don’t know which system type your cabin has, our system identification guide covers how to tell.
A note for lake associations and rental hosts
This guide is built to be shared — whether you’re part of a Whitefish Chain or Gull Lake association distributing guidance to members, or you manage a rental property near Crosslake or Pequot Lakes and want something simple to post for every guest turnover, feel free to print and post this list directly.
A word on garbage disposals
If your cabin has a garbage disposal, it deserves its own guest note — food scraps add solid load to a tank far faster than normal use, and a disposal used heavily by guests unfamiliar with a septic system’s limits (versus the municipal sewer many are used to at home) can meaningfully shorten your pumping interval. Some Brainerd Lakes Area cabin owners choose to disable or remove disposals entirely for exactly this reason, especially on properties with frequent rental or guest turnover.
Where to post this
The guest bathroom is the obvious spot, but a laminated card by the kitchen sink covering both flushing and disposal use covers more ground for a typical weekend’s worth of house guests. Whichever towns your guests are visiting from, a little guidance up front saves both the homeowner an unnecessary service call and the guest an awkward conversation about what they did wrong.
Keep it simple and keep it visible
A long, detailed list rarely gets read by a guest looking for the bathroom at midnight. The short “never flush” list above, printed in a large enough font to read at a glance, does more good posted where it’ll actually be seen than a longer, more thorough explanation buried in a welcome binder nobody opens.
What Not to Flush FAQ
Are “flushable” wipes actually safe for septic systems?
No — despite the labeling, they don’t break down the way toilet paper does and are a common cause of clogs and pump damage, especially on mound systems.
What should guests do if they’re not sure whether something can be flushed?
When in doubt, throw it in the trash instead — a simple rule that prevents almost every avoidable flush-related service call.
