Found off a 'Steam Pump Overseer' that guards the drain controls.

Drain is located at 50,40. Once you get there swim down in the water and you will discover it.

评论来自 Orik

A Steam Pump Overseer that has a higher drop rate of this item is located east of Coilfang Reservoir.

Had to kill about 20 overseers (after the Naga Claws quest) to get this item. The quest rewards and XP make it worth it. Wish it was automatic though.

Confirm coords 50,40.
Thats good and easy quest :)

评论来自 Maxwell

You can farm this while on "Balance must be Preserved." Simply use the seed at the same station even after you've completed the quest requirements for that location. The seed will continue to spawn Overseers.

Despite the requirement of level 59, it is not possible to obtain this quest at level 59.

What we did was get my level 59 character to the quest target for "Balance Must Be Preserved" while a level 61 was on said quest. The level 61 had not done the Drain Schematics quest. We spawned the steam pump dude several times until it dropped. The level 61 could see the drop, but I at level 59 could not. We tried all the loot types (free for all, etc) and had it drop each time.

It does drop when you don't have the Balance Must Be Preserved quest. But again, not for a level 59.

There are few Steam Pump Overseers up at a given time, and the respawn rate is fairly long.

The best way to quickly get these schematics is while on the quest "Balance Must Be Preserved" (https://www.wowhead.com/tbc/quest=9720). Every time you use the Iron Vine Seeds (https://www.wowhead.com/tbc/item=24355), a Steam Pump Overseer will spawn. These overseers you force to spawn won't yield experience, but they can drop the Drain Schematics, as well as Naga Claws required for "A Warm Welcome" (https://www.wowhead.com/tbc/quest=9728), and the Unidentified Plant Parts required for "Plants of Zangarmarsh" (https://www.wowhead.com/tbc/quest=9802) and "Identify Plant Parts" (https://www.wowhead.com/tbc/quest=9784).

There's no cooldown on the Ironvine Seeds. Just it will not force a respawn of a Steam Pump Overseer if one is already up that you forcibly spawned. However the one that guards the controls can respawn independently as well.

Yup, Balance Must Be Preserved is definitely the way to do this =p I was killing my fourth Overseer when AV popped, and just as I was resigning to have to come back he dropped the plans.

Ok yes this is farmable... you need the quest "Balance Must Be Preserved" kill the "Steam Pump Overseer" he will be standing in front of pump use that were provide by the quest to finish part of the quest plus it will resummon "Steam Pump Overseer"..kill him again if did not drop.. keep using to resummon him and repeat i did this as a 62 MS warrior took me 22 kills to get it...8% drop

I can confirm that you get zero exp for the Steam Pump Overseer. You can summon him endlessly using the Ironvine Seeds, but get between 10 and 14 silver per kill and some plant parts.

I had a L60 in party in an attempt to get the Drain Schematics quest, but they were not visible. It does look like a person needs to be on the Balance Must Be Preserved quest. Drop rate is still very poor.

评论来自 Allakhazam

i'm on the "Balance myst be prepared" quest, killed a dozen of them already, and still nothing

评论来自 Allakhazam

I confirm the theory! This item "Drain Schematics" only drops if you are on the quest "Balance Must Be Preserved"!
After that you just need to go to the big X on serpent lake (the entrance to coilfang instances) and them go deliver the quest. Its easy...

评论来自 Allakhazam

i've spent about 30 mins grinding off the overseer's and still no luck

评论来自 Allakhazam

I grinded Overseers for 1½ hour and it actually dropped.

评论来自 Allakhazam

Alright, instead of waiting for the Pump Overseers to spawn go ahead and get the schematics when you have the quest "Balance Must Be Preserved". You can use the Ironvine Seeds an infinite amount of times on the same pump. You will therefore have infinite spawns of Pump Overseers and eventually get the Pump Schematics.

评论来自 Allakhazam

You don't need to grinding to finish this quest... Go to the location at 50, 41 which is in the middle of the cross and swim down against the "stream". Then you will complete the quest. Realy simple.

评论来自 Allakhazam

The 3% to drop is a bit deceptive. The item seems to only drop if you are on or have completed the Quest "Balance Must be Preserved." I was grinding the Nagas and the Overseers for faction on my druid for an hour and there was no drop. Then I killed one Overseer while doing Balance Must be Preserved on my priest and it dropped off the first one.

评论来自 Allakhazam

He needs to get the item to drop.

评论来自 Thottbot

Dropped off Naga at Bloodscale Grounds. Drain Schematics quest is at 50,41, it's the Coilfang Resevoir.

评论来自 Thottbot

Right in the middle of the lake
go down the white glowing hole until quest completed
Thats ALL

P.s.: no water breathing needed

评论来自 Thottbot

I actually found the entrance by accidentally exploring the area. from the surface, just swim to the entrance of piping.. along the way, there is a spot where your breathing timer goes off. if you continue, it does come back, but youll have more than enough to get to the instance portals.

评论来自 Thottbot

No Pot Needed

评论来自 Thottbot

Drainpipe is at exactly 50, 41. Just swim out, then straight down into it. No potions needed, your breath timer will refill itself halfway through the pipe. This is the entrance to some instances, so everyone will eventually be very used to it. Coilfang, Slave Pens, Underbog.

评论来自 Thottbot

You get the schematics as a random drop; I got it twice off the Nagas on the north side of Serpent Lake within about 3 kills.

The drain is in the middle of Coilfang Reservoir; it's the huge structure on the map in the center. (it's all underwater). Swim to the center, and then dive briefly into the air bubbles coming up, and you will complete the quest. The actual coordinates are 50,40. You don't need any special equipment.

If you swim through the drain, you will get to at least a couple of instances. You don't need any special equipment or gear to get through. About halfway into the pipe, well before you run out of air, you move into an area that recharges your breath. You're still underwater, but you can breathe. After swimming awhile in the breathe zone, you'll come to normal water again, at which point you swim up to real air.

sorry about that i was doing the "natural armor" quest and had a pot running,was under water quite a while before it triggered this quest completion ,didnt realize how close to the surface i was :/

评论来自 Thottbot

I accepted this quest, but Ysiel won't take the schematics. No matter what I do, she still has the grey ? above her head and wont let me complete. I don't understand!

评论来自 Thottbot

I have farmed this for 2 hours already. Is it just me or is this quest item really rare?

评论来自 Thottbot

You DO NOT NEED a lock or pot to get to the instances there are spots of bubbles much like in sonic which refill your air meter

评论来自 Thottbot

I also farmed this for an hour before it dropped (off a Bloodscale Wavecaller, if you're interested). I wouldn't have even known about it except that I have two characters in Zangarmarsh. My Priest got it right away while killing Naga. So I went back with my Rogue and killed and killed and killed. If you've done the pre-requisites as mentioned above, then just keep trying. You should get it eventually.

评论来自 Thottbot

i have completed the quest but i still cant turn it in.I still have a grey ?When you read the quest it says completed but there is nothing saying completed in the quest log. did i miss something?

评论来自 Thottbot

For those of you that are having trouble with this quest, are you guys sure you pushed the "accept" button on the lower left corner of the quest page? I thought my quest was broken, but I forgot to accept the quest.

评论来自 Thottbot

Confirmed: you MUST complete "Disturbance at Umbrafen Lake" and " As the Crow Flies" before the plans will drop.

I farmed the Naga for hours, then read Thott more closely... Once these 2 quests were complete, the plans dropped off the first Naga I killed.

评论来自 Thottbot

In the middle of serpent lake, there is the coilfang resevoir. Go in the middle of the reservoir and swim down (x) until u see somtin suckin in water. Go in tht and u completed quest.

评论来自 Thottbot

it's important to note that if you're not able to turn the quest in, it may have been that you accidentally deleted the item from your bag; if it's deleted you can't turn the quest in.

评论来自 Thottbot

Didn't give me any Darkspear Trolls rep just Cenarion - it might have been changed

抽水泵结构图 is a quest related item - you can use it to accept 抽水泵结构图 quest.

So, to start the quest you need to loot 抽水泵结构图 item from any naga mobs around the area. Usually need to 1-2 kills to obtain this.
There is a large lake named Serpent Lake in the middle of Zangarmarsh. You need to swim to the middle of the lake toward the big metal construction.
There is a passage between the tubes, you need to swim close to count the task. Just beware of angry fishes in the lake, overpulling them may be fatal.

Coordinates (TomTom):

/way 50.22 40.99 Drain location

Still drops as of 2021-06-02 - but it can take a while. Keep killing and it will eventually drop. Best to combine it with the quest "Balance Must Be Preserved" since you are there for it anyways.

评论来自 too2fun

Appears you have to be on the quest for it to drop. I spent hours trying to farm it before i had the quest Balance Must be Preserved.

评论来自 greatbrownninja

This item will not drop untill you do some of the quests at the Cenarion Expedition hub. I farmed for 2 hours without a drop. Went back and did the chain up to "Balance Must Be Preserved" and got it after around 4-6 kills.

评论来自 kjeksomanen

17 kills before I finally got the item, so be patient.

评论来自 squidzorz

Even when on the quest Balance Must Be Preserved, it's not a guaranteed drop.

After killing all 4 Steam Pump Overseers at the pumps, I had to spawn 16 more to get it to drop.

评论来自 bbbhix

In order for these to drop you need to complete at least 暗泽湖的异常, but I would suggest completing 乌鸦的飞翔 as well which is given right after Disturbance and just requires you to wait a few mins. I was in a party with two of my characters and the Schematics dropped, but I was only able to loot them on one of the characters. I then went and did those two quests previously mentioned and was able to loot the Schematics within 2 kills afterwards.
