+1 Drain Water Per Click Wiki & Calculator

Dianeti is currently the strongest pump: ×4,000,000 Water per click, costing 15B Water or 759 Robux. It's the community's only S-tier pump. For most players the best purchase is simply the next pump you can afford — the full pump table with prices is on our pumps page.

The official description guarantees every click gives +1 Water as the unboosted baseline. Pumps multiply that: Water Pump Plus ×5, Lucky Clover ×12, up to Dianeti ×4,000,000. Check your current per-click value in-game and run it through our Water Per Click Calculator for per-second/minute/hour rates.

As of August 28, 2026 four codes are reported working: CTHULHU (1 Fish + 1 Cthulhu Ticket), ADMINAQUARIUM (Lava Aquarium), WATERHAPPY (Shark pet) and MYTHICFISH (Exotic Mosasaurus Fish). Codes are case-sensitive — copy them from our codes page.

Rebirth resets your Water level and pumps in exchange for a permanent multiplier that stacks across rebirths. The exact multiplier value and requirement haven't been published by any reliable source, so we don't print numbers — community guidance is to rebirth when your upgrade growth stalls, not early.

Hole is the strongest known mutation at ×20 a fish's value, followed by Venom ×10, Diamond ×5 and Gold ×2. Hole spawns rarely but its spawn chance gets roughly +10% during Black Hole weather (about 4 minutes). Values are player-measured, not official stats.

In order of impact: redeem all active codes, buy the next pump you can afford (the pump multiplier is the biggest factor), keep pets equipped, farm mutated fish during Poison/Black Hole weather windows and sell or display them, and rebirth once growth stalls. Our Best Pump Finder tells you exactly what to buy with your current Water.
