Water Pump
by peterwolfpl
Water Pump lets players drain large volumes of water from lakes, reservoirs and underground chambers by placing a pump on a wall.
What it does
The pump is installed directly on a wall next to a water-filled area and activated there. Once running, it steadily removes linked water until the level drops to the base of the pump, and the extracted water leaves through the outlet. Water can be drained from natural lakes, player-made reservoirs and even the ocean floor.
Players who want to empty caves, underground passages or sections of seabed for underwater bases and large construction projects can use the pump to reshape the terrain. A solid block placed in front of the outlet stops the discharged water from flowing out. The mod is client and server, and it is published for Fabric only, for the 1.21.11 – 26.3 range under the Apache License 2.0, which is not open source.
Key features
Quick draining
Large volumes of water in lakes and reservoirs can be removed in a short time with a single placed pump.
Wall placement
The pump attaches directly to a wall, so it fits into existing terrain without extra supports.
Connected water removal
Water blocks linked to the pump are drained automatically down to the level of its installation.
Outlet control
Discharged water exits through the outlet, and a solid block placed in front of it stops the flow.

Who it’s for: Survival players, builders working on large projects and server owners who want a simple way to clear water from wide areas.
How it compares
Connected Signs is a client and server Fabric mod for 1.20.1 – 1.21.1 under the Apache License 2.0 and open source, so it covers a different function and a different version range. DeleteButton is client-side only and limited to 1.20.1, while No more Infinite Water is server-side only for 1.18 – 1.18.2 under the GNU Lesser General Public License v3.0 only and also open source, so it targets infinite water sources instead of drainage.
