Talk:Pumps

How are they connected? Using wires? <-- Yes

Can't pump great distances? <-- See below

I assume if the outlet is located in an enclosure which is already completely full of water, the pump will not move any more water @ remove water from the inlet? Any tests done on this? E.g. pumping water from an 8x8 pool to a 4x8 room, does it remove exactly half the water? - Spinfx 01:13, 18 December 2011 (UTC)
 * if the outpump cannot generate anything in it's location, meaning it is completely submerged, then the inlet will also stop as one needs the other to funtion. you're on close to right track of how it works, water is removed from the inlet and the outlet spawns whatever it can to fill up its location.  typically if the intake is flooded, then the outpump produces MORE water.  eventually this cycles if the out leads to the in untill there is no more room for the out to make fluid. 96.15.250.45 03:58, 18 December 2011 (UTC)

Distance Limitations
Should we include a note in this article about the maximum distance over which liquids can be pumped? I've searched forums, and it seems that the maximum distance (measured by the wire laid down to connect the pumps) is 1000 blocks (2000 feet). I think this information is relevant to the article, and ought to be included. Thoughts? Threid 21:27, 7 December 2011 (UTC)
 * Exactly 1000? As in, it works at 1000, and doesn't at 1001?  If you have data that precise, then, by all means!  --Theothersteve7 21:37, 7 December 2011 (UTC)
 * After further research, it looks like it might be too early to give an exact length with any certainty. However, these forum threads seem to point to a maximum distance that's dependent on the number of wires in the connection, and 2000 feet (1000 blocks) is the number getting thrown around most often, probably because it's nice and round. In any case, I'm not sure that this information belongs here, or on the wiring page, so I'll leave it as-is for now. Threid 22:00, 7 December 2011 (UTC)
 * After checking what the source code states about this it seems that there may be exactly 1000 wires in a connection. So if you make a straight line you can pump liquids over a distance of 1000 blocks or 2000 feet. --Icke 16:28, 11 December 2011 (UTC)

Infinite fluid generation
I removed the following contribution by 86.218.22.26 re. connecting two outlets to one inlet, pending additional verification: "It also seems that this system can make infinite fluid generation quicker (should be verified)." Chibs84 20:01, 8 December 2011 (UTC)
 * Just tested on Single Player, was expecting it to fail and be a Multiplayer-only bug, but 2 outlets connected to a single inlet does indeed dupe water. It doesn't even need to be spammed, each pump action produces an extra pixel-high layer of water in a 5-block-wide tub. -Fishy 04:06, 13 December 2011 (UTC)
 * i was reading forum threads and it isn't 100% true to the two posts' words above. to be more exact, a SINGLE outpump will produce more fluid than original started if the intake pump is completely full.  having extra outpumps works slightly different but same results only much faster (after a delay of start up).  if there is still fluid to remove at the intake, the second outpump will then put out fluid while the first is working.  a second or third will trigger more often and steadily if the previous outpump is flooded.  basically if there is water still around it, it will only fill in gaps at its location.  if there is less gaps a outpump needs to fill than the intake pump provides, then the next outpump will function for remaining amount the outpump provided.  it also seems that the lowest and left most outpump operates first or maybe that is because it is shortest distance. 98.134.33.113 01:50, 15 December 2011 (UTC)

Infinitive Liquid Trick
If you happened to have seen the Infinite Fluids page, then this would work for you.

Items needed
1. Inlet + Outlet Pump

2. Timers (all types)

3. Wrench + Wire + Wire Cutter (optional)

4. Having the pyramid liquid duplicator

5. Create a man-made pool of liquid near your house (If you happened to have one like me, you're lucky) or find one nearby (Not too far since if the distance between the pumps is over 1000 blocks, it won't work)*

Steps
A) Create 3 blocks above your liquid duplicator, Must be 1 block higher and away from the top of your pyramid

B) Put the Timer + Outlet pump above the blocks created in  (If the 3 blocks is on the left, then timer is on the left. If on the right, then timer is on the right.)

C) Put the Timer + Inlet pump inside your pool of liquid

D) Connect the timer and the pumps with wire and connect the two pumps with wire

E) Activate one of the timers and you're done

*The pool must be at where the liquid flowing down from your pyramid reaches, or the pool will run out of liquid

 * while i admire your dedication on mixing methods, only one bug is necessary for pumps and is listed on both pages: if the inpump is completely submerged in fluid and the outpump leads to it, then the outpump generates more fluid than existed. the only case this isn't true, and i haven't tested yet, is when there is a huge vertical distance difference.  using pre 1.1 (ie the non-pump infinite fluid tricks), only speeds things up as far as pumps are concerned and you might as well just add more pumps instead. lastly, the 1000 blocks is due to wire's limit, not pumps, but same difference really.  96.15.132.196 19:12, 19 December 2011 (UTC)

1.1.2 Changes
I just tried using the "infinite liquid" tricks with pumps, but the outpump does not seem to be producing more water than the inpump, and only one of the outpumps is spitting out liquid. I am pretty sure the inpump is submerged. It is in a 2x3 hole, and the liquid (lava) is spreading out to adjacent blocks above the hole.--Thelizardreborn 15:06, 18 January 2012 (UTC)

There's apparently other conditions that also permit infinite liquid; I'm getting infinite water trying to transfer water legitimately from one reservoir to another. The reservoirs are ~30x45 blocks in size, and I can see both on the screen. (i.e. The water shouldn't be "despawning," although I can't fully see both reservoirs.) The inlet pump is at the bottom of one reservoir (fully submerged), while the outlet pump is at the top of the other (not a closed loop). I'm manually flipping a switch next to the outlet pump: The water in the outlet reservoir keeps rising, while the inlet reservoir's water level doesn't change at all. --Sinister Stairs 21:12, 24 February 2012 (UTC)
 * I also meant to note that I've successfully drained other [naturally occurring] reservoirs without infinite water being produced. Similar situations, with the inlet pump fully submerged at the bottom of the pool, but in those cases the inlet pools were located well offscreen.  --Sinister Stairs 21:20, 24 February 2012 (UTC)
