Water Strainer Mod Tutorial: Farm Tons of Resources with Ease

The Water Strainer mod is one of the most efficient passive resource-farming mods available for Minecraft. By placing strainers in flowing water, you can automatically collect general items, fish, enchanted books, and rare drops — all without lifting a pickaxe. In this guide, you’ll learn how to build and place strainers, maximize your efficiency, and keep your strainers fed with bait using worm farming.

Understanding Strainer Efficiency

Not all water is created equal when it comes to the Water Strainer mod. Your strainers will perform significantly better in flowing water, and your biome plays a direct role in your efficiency bonus. It is also important to keep strainers away from each other, as adjacent strainers negatively impact performance.

To check how efficient your current setup is, you can use the Efficiency Meter. Simply right-click on the strainer base with the Efficiency Meter to get a detailed readout of your current bonuses and penalties.

For example, a readout might show a bonus efficiency of 13%, a strainer type bonus of 25%, a small deduction from the fluid level, and no bonus from the biome. That biome result is actually bad news — your biome is one of the best ways to boost efficiency.

Biome Efficiency Bonuses

Certain biomes grant passive efficiency bonuses to all strainers placed within them:

Deep Ocean: +10% efficiency bonus

Beach: +15% efficiency bonus

River: +20% efficiency bonus

If you have the option to set up your strainer farm in a river or deep ocean biome, it is well worth the extra travel.

Crafting a Strainer Base

The foundation of your setup is the Basic Strainer Base. It generates items passively while submerged in water. To function, it requires a strainer placed in the slot on top and water flowing over that top section. Place the base down in the water, insert your chosen strainer, and the mod will handle the rest.

Types of Strainers

There are several strainer tiers, each offering different durability and efficiency bonuses. Choosing the right strainer for your stage of the game makes a big difference in output.

Survivalist Strainer

The basic entry-level strainer. It has 120 uses and collects general items. Press U while hovering over it in your inventory to see the full list of items it can collect.

Solid Survivalist Strainer

A step up from the basic version, this strainer provides a +10% efficiency bonus and offers 720 uses before it breaks.

Reinforced Strainer

The most powerful tier, granting a 25% efficiency bonus. The Reinforced Strainer can also be enchanted, opening up three powerful enchantment options:

Efficiency: Increases the speed at which items are gathered

Unbreaking: Increases the strainer’s durability and total uses

Fortune: Increases the quantity of items collected

Luck of the Sea: Increases the chance of receiving rare item drops

Strainer Types: General vs. Fisherman

Beyond the tier of the strainer, there are also two functional categories that determine what your strainer collects.

General (Survivalist-Type) Strainers

These collect basic, commonly needed items that would otherwise require manual farming. Think of them as your everyday resource passively topped up over time.

Fisherman Strainers (Levels 1, 2, and 3)

Fisherman strainers are specialized for aquatic and luck-based loot. They can collect fish, bones, enchanted books, and other valuable items. Three tiers of Fisherman strainers are available, with higher tiers unlocking better loot tables.

How to Attach a Strainer and Check Its Status

To attach a strainer to your base, place the strainer base in the water and ensure the top block has water flowing over it. Then, right-click the strainer net itself to open the interface.

Inside the interface, you will see a status readout. If the status reads “No problems detected,” your strainer is working correctly. If it shows “Bait is missing,” you will need to supply bait — most commonly worms — before the strainer will operate.

The Bait Pot

To reduce how quickly your bait is consumed, craft a Bait Pot using a flower pot and iron bars. Place the Bait Pot in the second slot of the strainer interface to slow down bait consumption and keep your strainer running longer between refills.

Getting Worms for Bait

Worms are the primary bait used in the Water Strainer mod, and there are two main ways to obtain them.

Method 1: Garden Trowel

Craft a Garden Trowel using one brick and one stick. Use it on grass or farmland blocks to dig up worms. The success rates are:

Grass blocks: 25% chance of yielding a worm

Farmland blocks: 50% chance of yielding a worm

For the best results with this method, till your farmland first and then use the trowel on it. Hold the farmland in place before breaking it with the trowel to give yourself more chances per block.

Method 2: Worm Bin (Recommended)

The more sustainable and efficient option is the Worm Bin. Place food items into the worm bin and it will convert them into both fertilizer (bone meal) and worms. Different food items have different worm yield rates:

Apples: 100% chance

Carrots: 75% chance

Melon & Beetroot: 50% chance

Berries: 50% chance

Potatoes: 25% chance

Apples and carrots are your best bets for maximizing worm output from the worm bin. Set one up early in your playthrough to ensure you always have a steady supply of bait on hand.

Summary

The Water Strainer mod is a powerful and beginner-friendly addition to any Minecraft survival playthrough. By setting up strainer bases in flowing water — ideally in a river or ocean biome — and keeping them stocked with worms, you can passively farm general resources, fish, and rare enchanted items with minimal effort. Upgrade to Reinforced Strainers, enchant them with Fortune or Luck of the Sea, and pair them with a Bait Pot and Worm Bin for maximum efficiency.
