Sewer door deletion, or throne door deletion, is a major glitch that removes the shutter door on the back of the throne in Hyrule Castle. It's usually done as a prerequisite to dungeon ID swapping.

You delete this door by copying the state of an open door in Tower of Hera over it. Deleting the sewer door is an effect that persists when you save your game.

It can be accomplished by two methods: using the Somaria Door glitch, or using two bottles for two YBAs in a row.

Somaria method

In the somaria method of sewer door deletion, your goal is to Door Juke the transition by holding the somaria block, then Somaria Door by pushing the block over the transition.

You should hit a star tile, and not open the select menu, before performing this glitch. That will prevent heavy VRAM corruption from being one of its effects. The glitch still works if you don't take this precaution, but you'll have to save and quit and then hard reset, and also it might crash a Super NT.

To start, face the door and throw a somaria block into it. Move a bit into the door and pick up the block.

Once you're somewhat into the door, you can tap up to snap to a lower position, and you can throw the somaria block to the left to bounce off the door frame and get it deeper into the door.

When you're deep enough in the door, you'll snap into a position where you can hold up the block and only see the block, not Link, as shown above. From this position, don't throw the block left anymore -- you'll throw it over the wall.

You need to get still deeper to juke the door. Face up, throw the block, move exactly 2 pixels down while the block is in the air, and pick up the block again.

An effective way to move exactly 2 pixels is to boots-buffer twice (tapping down and A at the same time) while the block is in the air.

Tap up while holding the block. You should end up in a position 8 pixels lower, where you can see half of the block. You have now juked the door -- you're past the transition.

The juked position

Now you need to get back above the door transition while the block is below it. Face up, throw the block, and boots-buffer up once.

Pick up the block again, and don't press a direction -- that would snap your position again, and undo what you did. You should be able to see about 3/4 of the block sticking out of the door now.

Ready for the somaria door glitch

Throw the block (without pressing a direction), and wait for it to land. Then tap down. If you hit a star tile earlier, the screen will scroll down a little farther, and you might see some light visual corruption -- you can mirror and go on with your game.

The slightly-scrolled screen if you hit the star tile like you should

If you didn't hit a star tile, you'll get heavy VRAM corruption, and then you should save and quit and hard-reset the game. Either way, you did the glitch, and the effect will be saved.

oh no what did you do

Two-bottles method

Bring two bottles to Hyrule Castle so you can do two subtile YBAs. You won't have an opportunity to take damage or use magic in between, so the first bottle has to be red, so it won't refill your hearts and magic and make the second YBA impossible. The second bottle can be red or green.

Make sure you're not at full health. Hold out your sword and move sideways into the door until you're on the bottom pixel you can be on. On the Link sprite, two rows of Link's hat are visible.

In position for the first YBA

Equip a red potion, and press down and Y simultaneously. The screen will fade to an ellipse that's mostly off the bottom of the screen.

The red YBA effect

A side effect of a downward YBA is to Door Juke you past the door transition, so now you need to back up to line up for the second YBA.

Carefully tap left or right until you reach this position. You can't see Link, but you can tell by the way the camera moves. A row of lighter pixels on the doorway -- the second from the bottom of the screen, which is the third from the base of the door -- should be the bottom pixel on your screen. If you overshoot by one pixel, it's okay.

In position for the second YBA

Do a YBA again -- select a red or green potion, and press down and Y simultaneously. The screen fades out again.

You won't be able to see the effect, but if you successfully did the two YBAs, the sewer door will be deleted. You can mirror out or save and quit, and go on to do the glitch you're deleting the throne door for, which is presumably dungeon ID swapping.

Unfortunately, you only get one chance at the second YBA.

If you fail the second YBA, you might end up stuck in the wall here
