Probably Stolen Water Purifier: Limits and Upgrades
The Water Purifier is an overnight machine, while the HydraTech Micro Water Purifier is a separate handheld item with durability. The community machine reference reports a normal unmodified limit of 99.26% purity, so repeatedly running the same setup does not necessarily reach Pure Water. Quality modules are the documented way to change that limit. Test the actual composition and read the machine's installed totals before assuming the remaining contamination means the device is broken.
Identify which purifier you own
The shared name causes two different questions to be mixed together. The Water Purifier belongs to the overnight machine chain, while the HydraTech Micro item performs a limited immediate treatment and wears out. The supplied water-business recording shows both kinds of equipment appearing in the same expanding setup, which makes the distinction especially important when copying it. A tooltip about durability on one item is not evidence for the nightly capacity of the other.
The handheld item reference describes restrictions on water that is already sufficiently pure and on amounts its remaining durability cannot cover. A refusal in that context can therefore be a condition of the item rather than a missing machine upgrade. Check its exact name and current durability before searching for an overnight power problem. For the broader choice between methods, use the purification-method guide instead of expecting both devices to perform identical work.
Give the overnight machine a real batch
The machine reference describes cleaning the water in a container during the night. Place a batch you can identify into the process and check its starting composition before sleeping. That produces a useful comparison the next morning instead of trying to remember whether several similar bottles were treated. The supplied video repeatedly tests water and compares quality, illustrating why a visible measurement is more useful than a seller's claim that the supply is already excellent.
Read the operating and power information for the machine you actually own. Having a purifier in inventory is not the same observed condition as a working overnight setup with water assigned to it. The official patch material also contains a Water Purifier price adjustment, so a launch-video purchase price should not become an unqualified current quote. Compare the actual offer when buying and the actual result when operating; those are separate checks.
Understand why purity can stop rising
The community machine page describes a floor for remaining contaminants and gives 99.26% as the ordinary limit without the relevant Quality effect. That is already within High-Quality Water in the water-grade reference, but below its Pure Water category. The distinction explains why a machine can be doing useful work while failing to reach the grade a player has in mind. Do not interpret a plateau by itself as proof that an unlimited number of extra nights will eventually finish the job.
The game manual transcription also distinguishes basic cleaning from reaching the highest grade with a properly equipped machine. It supports diagnosing the limit rather than assuming every filter and purifier is equivalent. Check the current grade and remaining components before purchasing more of the same treatment. If the reading is stable and the setup is unchanged, the evidence points toward understanding the limit, not inventing a secret container that automatically removes it.
Choose the module for the actual limitation
Quality and Performance are different statistics in the module system. The purifier reference links Quality with purity limits, while Performance affects the amount of processing rather than automatically proving a higher final grade. A player who wants a cleaner eventual result is therefore asking a different question from a player who wants the same operation to progress faster. Read the installed totals and the resulting water rather than judging a module only by its name or resale value.
The supplied playthrough eventually shows a heavily upgraded water setup, but the displayed result belongs to that particular combination of equipment. It should not be copied as the baseline output of a newly purchased machine. The modules page explains the broader distinction between speed, power and output quality. Use it to select a deliberate change instead of adding every attractive module and losing track of which statistic addresses the plateau.
Verify the result and the label
Water grade follows actual purity, while the item's displayed label can be inaccurate. The supplied recordings show the player becoming more careful about testing sellers' water, and the water reference distinguishes the measured result from the label. After overnight treatment, check what the batch actually became rather than assuming its old label updated correctly. A machine result and a marketing description on the container are not the same piece of information.
This also prevents misleading comparisons between two similar-looking bottles. One can hold a differently treated mixture or have a label that does not match the actual contents. Keep the containers and tests identifiable while evaluating an upgrade. The material does not justify inventing a fixed sale price for every purified bottle, since volume, container, grade and the actual trade all have to be kept separate.
Troubleshoot without buying a duplicate blindly
When the machine appears ineffective, first check identity, assigned batch, operating setup and measured before-and-after purity. If the batch improved but stopped below the desired grade, inspect the documented limit and Quality configuration. If you are using the Micro item, inspect durability and its stated refusal conditions instead of following an unrelated overnight guide. Those checks address different causes that the similar item names often hide.
Exact output for an unverified mod, an unusual mixture or a changed game version remains Pending confirmation (待确认). The supplied material does not support a promise that every problem is solved by purchasing another purifier or running one more night. Once the device is working, use the water-source guide to secure suitable input and the purification guide to choose treatment based on what the water contains. That keeps the equipment question distinct from both obtaining water and deciding which contaminants must be removed.
Keep a purchase-price correction dated
The official October 30 hotfix notes state that the Water Purifier price was reduced from 300 to 250 Credits and that the change had been missed in an earlier patch note. The community machine reference lists the lower value as well. That agreement is a better basis for describing the documented adjustment than copying an earlier purchase from a recording. It still should not be confused with a promise that every trader's final counter offer must match a base figure exactly.
The price issue is also separate from the machine's working limit. A player can have bought the correct item at a different historical price and still need to inspect the installed Quality effect when the water stops improving. Conversely, paying the expected amount does not establish that the batch, power and module setup are already correct. Keep acquisition, operation and output measurement as separate checks so that a resolved price discrepancy does not hide the actual purification question.
