Food, water and the day the taps stop

Fill every container before the taps stop, rack food so the pantry counter is real, and treat rainwater before you drink it.

Food, water and the day the taps stop

Fill every container before the taps stop, rack food so the pantry counter is real, and treat rainwater before you drink it.

What to do while the taps run

Water is the first tutorial job because the mains do not last. The compiled building clock says the taps and the power stop for good on day 3, and the phone network drops the same day. Objective footage words it as a Day 2 task, Fill every container before the taps stop, and shows the power already gone by the quiet day logged as Day 4. Do not wait to see which sentence is newer. Fill containers the day the objective appears.

On Night 0 the blue Cleaning Bucket under the sink holds 10 L. Place it in the tub, fill it, and rack it. On Day 2, fill every container you have. A stored-clean-water counter in that footage read 141 L, which is an example from one run, not a quota.

Containers

Container Capacity How you carry it
Cleaning Bucket 10 L, open top, starts empty Both hands. A full load is listed at 37% slower
1 L Bottle 1 L, sealed 1 bag slot
Sealed 2 L Bottle 2 L, sealed 1 bag slot. Hold F to drink
20 L Jerrycan 20 L, sealed Both hands. Full load listed at 40% slower
Rain Barrel + Funnel 20 L, open top Both hands. Full load listed at 40% slower
Bathtub 60 L in the building notes Fixed. Not a carried item

A separate note says a full 20 L jerrycan or cleaning bucket cuts speed to 60%, and that even empty those containers leave you at 88%. Bottles do not slow you. Put heavy water down before you climb.

Tap rates in the same notes: kitchen 1.3 L/s, bathroom 0.9 L/s, tub 2 L/s, heater 0.6 L/s. The tub is the fastest fill if you are standing there anyway.

Drinking and treating

Hold F to drink. One recorded sip was 0.5 L. The ration lines used by the rules page are:

Plan Food and water for the day
Full 2 portions and 2 L. Normal recovery and stamina
Reduced 1.5 portions and 1.5 L. Stamina recovery gets weaker over time
Emergency 1 portion and 1 L. Fatigue rises and max stamina falls over several days

If hunger or thirst drops below 20, the same notes say you take 1 damage every 5 seconds, down to 5 health, until the meter is back above 26. That is a rules-page figure, not a number read off a single HUD frame.

Rain and other open water are untreated. Treatment Tablets are listed at 10 L per use and 3 uses. They were seen in the bathroom mirror cabinet on Night 0 in a tips video, and again on a shelf beside bottles on Day 6. Boiling is the other method named for collected water. Clear water is not automatically clean.

Day 6 rain, in the building notes, runs 09:00 to 17:30. An open container on the balcony is listed at 2.4 L an hour. Roof barrels catch more than a balcony bucket, and that water is still untreated. A storm can tip loose roof containers. Brace a barrel with a board or bring it inside. Thunder covers other noise while it lasts.

After the mains die, a roof tank is a finite reserve. Once the riser is open the taps run slowly until the tank is empty, so fill everything while that water lasts. The basement cistern is described as the last large reserve. It does not refill, and it is untreated.

You can pour from a bucket into an empty bottle. When the bucket is empty, rain can fill it again. More buckets means more catch, and more weight.

Food

Move food onto the pantry shelves so the portion counter is telling the truth. Tins need a can opener, or the Spoon pass. Keep the opener with the tins.

Food Portions Limit
Tinned tomatoes, corn, peas, fish 2 1 bag slot. Tins do not spoil
Crackers 3 1 bag slot
Rice 6 Cook before eating. 2 bag slots
Fresh greens 2 Spoils in 4 days
Fridge leftovers 2 Spoils in 2 days
Wrapped raw pigeon 2 once cooked Cook before eating
Cooked pigeon 2 Spoils in 3 days

Eat food that spoils before you open a tin you could have saved. Rice is the largest single portion count and still has to be cooked. Cook only at the marked open-air station on the roof. A covered pot and a Portable Gas Stove (both hands, 4 fuel) are the cooking tools. The Cook class, if you bought it, adds one portion to a full batch, uses half the fuel, and keeps cooked food two extra days. It does not create food from an empty tin.

Seedlings are listed as needing about 1 L of water every two days. Fast greens are ready in about six days. Dry soil stops them.

Keep opened food sealed and off the floor. That line is attached to the floor 11 clinic notes and to the emergency guide.

A supply run that does not waste the day

  1. Bank water before you hunt for extra food.
  2. Bring the pantry counter up, then check Rations so you know which plan you can afford.
  3. Leave a can opener, tablets and one sealed bottle in the flat even if you carry a bucket out.
  4. Walk the hall. Sprinting is loud, and a full bucket already slows you.
  5. If Mara's radio objective is up, hold back 2 portions for her. The trade is across the balcony gap.
FAQ

Frequently Asked Questions

What are you trying to do in 30 Floors Up?

The Roblox listing asks you to last 100 days in an apartment 30 floors above a zombie outbreak. You store food and water, barricade the flat, and move quietly. Solo play and a team of up to four (you plus three friends) are both in the description. A server holds 30 players.

Which floor do you start on?

You start on floor 30 of Bellwether Heights, in flat 3004. The door numbers around the corridor include 3001 Ruth, 3002 L. Brandt, 3003 Daniel and 3005 Mara. Later objectives send you down the building. You do not start at street level and climb to a rooftop boss.

Are there working codes?

No code string is confirmed, and checked lobby shop tabs (Classes, Shop, Gems, Donate) did not show a code box. Codes published for other Roblox games, including 18 Floors, are for those games.

What did Update 2.0 change?

The live experience title reads [UPDATE 2.0] and the Roblox page shows an update stamp of 11/7/2026. That stamp does not include a public list of new floors, weapons or balance changes. Treat detailed routes from early-November footage as the last observed objectives, and re-read the in-game objective list if a step no longer matches.
