As simple as that sounds, there's actually quite a bit of thought that goes into it. You need a consistent source for your water, a way to ensure and improve its quality, ways to store it, and information on when it's going to be most valuable. Here's everything you need to know to successfully become a water trader in Probably Stolen. How To Get Constant Access To Water The Water Purifier is open and contains a full water pitcher in Probably Stolen. When you first start the game, the only way to get water is to buy it from people who come to your window. While this works for the first few days, if you're wanting to scale your water trading, you'll need some way to have constant access to water. You can get this by purchasing the Water Trading upgrade from Joe Wild's network for 300 credits, then the Gutterflow On Tap upgrade for 250 credits. This gives you a tap directly in your store with constant access to Gutterflow with variable purity depending on the day and a small amount of water trading supplies including the water trading manual, a pitcher with a filter, testing strips, purification tablets, and a few bottles. You can access these perks automatically if you choose to start your run with the Water Merchant scenario. Water Testing And Purification The Retired Water Merchant sells supplies at the counter in Probably Stolen. As mentioned, water has varying grades that affect who will buy it and what it can be used for. Pure Water has 99.9% or higher purity and is worth 80 credits per liter High-Quality Water has 99% to 99.9% purity and is worth 60 credits per liter Basewater has 98% to 99% purity and is worth 40 credits per liter Ghostwater has 96% to 98% purity and is worth about 27 credits per liter Rustwater has 90% to 96% purity and is worth 10 credits per liter Gutterflow has 80% or less purity and is worth only 4 credits per liter Most customers will only buy water that has a Basewater quality or higher. You can sometimes fudge the label with the labelmaker, but keep in mind that most scavengers and people from the higher levels will have ways to test the water and catch you in a lie, which can affect your reputation. Because of this, it's best to try and get the water to genuinely match the higher purity levels. You can do this with various cleaning tools. Start by testing the water with a test strip or Aquascan; test strips are one-time use while the Aquascan is reusable, but they both tell you what purity level your water is currently sitting at. Once tested, you can use a variety of tools to filter and clean the water. Water purification tablets are the most widely available cleaning tools. They're one-time use and bring the quality of the water up a little bit at a time. It can take several tablets to raise the purity level of your water if it's in a larger container. Filters take impurities and contaminants out of the water and are often reusable to a point. A basic water filter goes in a pitcher and has 400 durability, using a couple points per 100 mL filtered; they don't regenerate and need to be replaced when they hit zero durability. An advanced water filter regains 50 durability every night. A Hydroreed filter has 250 durability but can be relatively cheaply produced with hydroponic farming. A HydraTech Micro Water Purifier brings any water up to Basewater purity all at once. It's got 300 durability and loses one durability per 100 mL of water affected. These need to be replaced when they hit zero durability. A Water Purifier machine, available from the Retired Water Merchant or Dr. Jackson, can bring water up to High-Quality purity or higher with Quality modules installed. It cleans overnight so you can always have at least one clean pitcher for the day. Beyond these tools, you might also consider picking up some storage options. A Bottle Printer can make sure you have storage containers available at all times while a Water Tank gives you 20,000 mL of storage or 50,000 mL with expansion. You can get both from Dr. Jackson or the Retired Water Merchant. Taking Advantage Of Water Shortages The Shady Customer trades information about Nutrifruit at the counter in Probably Stolen. Water sales are pretty profitable all the time in Probably Stolen, but can be even more valuable in the event of a water shortage, usually caused by the water treatment plant on the station going down. You can sometimes know in advance if this is going to happen by paying the Shady Customer that comes to your window every week or so 50 credits. If you have enough notice, you can produce a large amount of inventory and put water in your showcase to attract more customers looking for it. Try to keep a storage bay filled with water during these events. You can track how long you'll need supplies in your calendar at the beginning of every day.
