Official patch notes: not available
The developer has not published patch notes. The Roblox page's 'updated' stamp and event banners are the only official freshness signals, so the update watch cites those with dates.
Fill Water Tanks Sources & Verification
Every table on FillWaterTanks names its source and checked date. This register lists all of them — what each is used for, its type, and the date it was last verified (2026-10-03).

Absence register
Source types that do not exist for this game
Stating what is missing is part of the record: these are the source types a typical Roblox site would use that Fill Water Tanks does not have.
Official stat tables or a code list: not available
Numbers Going Up publishes no capacity, rate, or code documentation. Every game number on this site is therefore community-documented and attributed, never presented as official.
Official Trello board: not available
No official board was found at the checks (see the community-links page). Any Trello link elsewhere is unofficial.
Verified official Discord invite: not available
The group page hosts the developer's social links, but no specific invite was verifiable as official at the check. Use the group page directly.
Established code-tracker coverage: not available
The major Roblox code trackers (Pro Game Guides, Try Hard Guides, Destructoid, GameRant, Roblox Den) have no Fill Water Tanks pages, which is itself part of the codes page's evidence.
A large official wiki: not available
The Fandom wiki exists but is small — one substantive mechanics page (Employees) at the checked date. This site consolidates what its sources cover and labels the gaps.
How sources are weighted
- Official (Roblox page, games API, group page) — identity, description, dates, counts, event banners. Never contradicted by lower tiers.
- Fan guide (AllThings.how) — the only long-form written guide; starter prices and loop details, dated to its August 27, 2026 update.
- Community wiki (Fandom) — game-specific tables such as the employee ladder; treated as current at its checked date.
- Credited creators — mechanics visible in walkthroughs (pipes, buttons, rebirth behavior); labeled creator-reported when no second source confirms.
- Search surfaces — negative results (no codes, no Trello) recorded as dated checks, not absolute claims.
When two sources conflict — as code claims regularly do across games — this site shows both sides with their dates instead of averaging, and an unverifiable string is removed rather than hedged. That policy lives on the about page.
What this site never cites
Anonymous code lists with no redeem-screen evidence, clip captions that name no source, content farms that republish each other's guesses, and any destination claiming to be official without appearing on the developer's own page. A string that cannot be traced to a checkable source is removed from this site rather than hedged — that is why the codes page lists checks instead of strings, and why the links page says "not found" instead of guessing a Trello URL. Corrections that bring a checkable source are always welcome: verified claims replace dated ones, and the checked date moves with them.
Recheck schedule
The game updates frequently (documented updates in August, September, and on October 2, 2026). Codes and community links are rechecked after every named update; mechanics tables are rechecked when an update touches their system. The site-wide reference check is dated 2026-10-03, and each page carries its own dates so older observations never masquerade as current ones.
Provenance FAQ
Why do some numbers carry a creator's name?
Because the walkthroughs (Quacks, Clout Brothers) are the only place certain mechanics are documented — crafted-pipe recipes, rebirth reset rules, button prices. Naming them lets you weigh the claim and re-verify it in game; an unattributed number teaches nothing when it breaks.
A creator video changed its numbers. What now?
Send it through the contact page with the page URL. Source conflicts are shown both ways with dates until one side is clearly current, then the table updates with a fresh checked date and the losing claim stays in evidence where it helps.
Is the site's own calculator a source?
No — it is arithmetic on your inputs. Its method and rounding are printed under the tool, and every game number it touches (tank capacity, employee percentages) comes from the sources registered above.
