Pull the Plug

Pull the Plug is a side quest which occurs at Thicket Excavations .
==Quick walkthrough==
==Detailed walkthrough==
Talking to Sully Mathis reveals that he wants help with unblocking some underwater pipes at Thicket Excavations. Though he can be asked why, he will respond evasively even if successfully persuaded. He will offer 50 bottlecaps as base pay, which can be haggled up to 75 caps and then 125 caps with persuasion checks.
The pipes can be located by finding the bubbles on the surface and swimming down (water is irradiated, 10 per second). Each pipe can be fixed by simply turning a yellow valve located on the pipes. There are two exits from inside the dam, and there is a lift and a staircase which are on opposite sides of the dam. The lift has a button at the top and bottom, and having it in the right position prior to navigating can be helpful. Underwater breathing boosts such as the Aquaboy/Aquagirl perk or mirelurk cakes can be helpful but are not necessary, as the valves are not very deep underwater. The locations are in a triangular pattern; it can also help to scope them out from above before diving in as the bubbles are clearly visible. A hazmat suit and/or some Rad-X will help to counter the rads in the water.
After fixing the pipes and speaking to Sully, the player character must start the pump near where Sully is standing, which will spawn two leveled mirelurks. After killing them and speaking to Sully again, he will pay the player character, ending the quest.
===Post-quest===
After one day has passed after completing the quest, and allowing the cell to reset, one may come back to Thicket Excavations to find that the quarry has been drained and occupied by raiders. At the very bottom of the dig site, the player character will find Sully (now a much tougher boss, having a minimum level of 30) and several mirelurks in pens. The mirelurks can easily be killed if the player character does not open the doors leading into their enclosures. In many cases, a single frag grenade should suffice. Sully seems to be breeding the mirelurks.
==Quest stages==
==Notes==
* Leaving the excavation zone before completing the quest will reset most of the containers on the location. 
* Inside the only lit trailer, the player character can find the "Thicket Excavations Terminal" which holds the Sully's journal holotape. The tape is priced at 888 bottlecaps, which is unusual considering it is simply a personal journal.
* Inside the same trailer, there are at least two locked containers with modified weapons and chems.
* With high enough Charisma, Sully can be haggled with three times for up to a reward of 125 caps.
* If using power armor to navigate underwater, sometimes the water breathing effect does not occur when returning to it in certain areas which can result in drowning. It seems to be in regard to whether or not there is an underwater ceiling above one's head.
* Using power armor while fixing the pipes can leave one at a disadvantage, seeing that it makes them hard to get to and traversing the underwater area takes considerably longer than quickly shutting off the pipes and returning later.
* If Sully is killed before starting the quest, the quest can be started by turning the valves underwater, though the reward is fairly reduced.
* If Sully is killed by the player during the mirelurk attack, the objective to speak to him will fail, but the quest itself will still be marked completed as normal. The bargained reward can be retrieved from his corpse.
* If Sully is killed at any time before the raiders move in, then his position will be filled with a leveled "boss raider."
* As the player character is fixing the pipes to drain the water out of the quarry, one does not need to search underwater for loot but can just focus on fixing the pipes. The area is farmable upon revisiting on a set timer so one can feel free to wait.
* Most companions, even those who normally like or dislike haggling attempts, have no reaction to any dialogue options in this quest.
==Bugs==
* If one sleeps for 24 hours after killing the mirelurks but before talking to Sully, this quest's quest log entry will freeze and not go away.
* The quarry may not drain regardless of how much time has passed since the completion of the quest.
* The quest may not start due to Sully being stuck in a dialogue loop.
