Why Your Off-the-Grid Sims Can’t Use Plumbing (And How to Fix It)
If you’ve built a dream off-the-grid homestead in The Sims 4—complete with solar panels, composting toilets, and rain collectors—only to find your Sims yelling about clogged toilets or refusing to shower, you’re not alone. Many players are frustrated by the message: “Sims 4 plumbing doesn’t work off the grid”. This isn’t just a glitch—it’s how the game’s mechanics are designed. But don’t worry: with the right setup and knowledge, you can keep your eco-friendly household fully functional. Let’s break down exactly what’s happening and how to solve it.
What Does “Off the Grid” Mean in The Sims 4?
Before diving into fixes, it’s crucial to understand what “off the grid” actually means in The Sims 4, especially with the Eco Lifestyle Expansion Pack installed.
In real life, “off the grid” typically refers to living independently of public utilities like electricity, water, and sewage. Similarly, in The Sims 4, a lot is considered “off the grid” when it doesn’t connect to municipal water or power.
However—and this is key—standard plumbing fixtures (like regular toilets, sinks, and showers) require a water supply to function. If your lot isn’t connected to the city water system and you haven’t installed alternative water sources, those fixtures simply won’t work.
According to Maxis’ official patch notes (June 2020), “Plumbing appliances require either municipal water or a rainwater collector to operate on off-the-grid lots.”
So it’s not a bug—it’s intentional design to encourage sustainable gameplay.
Why Does Sims 4 Plumbing Fail When Off the Grid?
1. No Municipal Water Connection
By default, when you toggle a lot to “off the grid” in Build Mode (Lot Info > Utilities), it disconnects from both power and water utilities. Without a replacement water source, plumbing fixtures have no water to draw from.
2. Missing Rainwater Collectors
Rainwater collectors are essential for off-grid water supply. Each collector provides a limited amount of water per Sim per day. If you have too few collectors for your household size, water runs out—leading to plumbing failure.
Tip: One rainwater collector supports up to 2 Sims for full plumbing use (showers, toilets, dishwashing). For a household of 4, you’ll need at least 2–3 collectors.
3. Wrong Fixtures Installed
Not all plumbing is created equal. Regular toilets and showers won’t work without water. You must use eco-friendly alternatives like:
- Composting toilets (no water needed)
- Outdoor showers (can work off-grid if paired with rainwater)
Standard indoor showers, bathtubs, and dishwashers require water, even if powered by solar energy.
Step-by-Step Fix: Make Plumbing Work Off the Grid
Follow this checklist to ensure your off-grid home supports full plumbing:
Step 1: Confirm Lot Status
- Go to Build Mode > Lot Info > Utilities.
- Toggle “Off the Grid” only if you’re ready to manage your own utilities.
Step 2: Install Rainwater Collectors
- Purchase Rainwater Collectors (found under Outdoor > Eco Utilities).
- Place at least 1 per 2 Sims. More is better in dry weather.
Step 3: Use Water-Efficient or Waterless Fixtures
Replace standard plumbing with off-grid-compatible options:
| Fixture Type | Water Required? | Off-Grid Compatible? |
|---|---|---|
| Standard Toilet | Yes | ❌ |
| Composting Toilet | No | ✅ |
| Standard Shower | Yes | ❌ |
| Outdoor Shower | Yes* | ✅* (with rainwater) |
| Sink | Yes | ❌ (unless rainwater available) |
*Outdoor showers work off-grid only if rainwater collectors are installed and not empty.
Step 4: Monitor Water Levels
- Click on a rainwater collector to see its current water level.
- During droughts (common in certain neighborhoods like Evergreen Harbor), water replenishes slowly. Consider reducing water usage or adding more collectors.
Step 5: Use the “Eco Footprint” Tool
- Keep your neighborhood’s Eco Footprint Green or Neutral.
- A polluted (Industrial) footprint can reduce rain frequency, limiting water collection.
Common Misconceptions About Off-Grid Plumbing
Many players assume that “off the grid” just means solar panels = full functionality. But water and power are separate systems in The Sims 4.
- ❌ Myth: “If my house has solar panels, plumbing should work.”
✅ Truth: Solar panels only power electricity. Water requires rainwater collectors or municipal supply. - ❌ Myth: “Composting toilets are just decorative.”
✅ Truth: They’re fully functional, hygienic (after maintenance), and do not require water—perfect for off-grid builds.

Advanced Tips for Seamless Off-Grid Living
- Combine with the Cottage Living Pack: Chickens and cows don’t require plumbing, making them ideal for off-grid farms.
- Use Eco-Friendly Showers: The “Eco Shower” from Eco Lifestyle uses 30% less water, stretching your rainwater supply.
- Place Collectors Strategically: They work best on roofs with high exposure. Avoid placing under trees or overhangs.
- Backup Plan: Keep one room connected to utilities (e.g., a guest bathroom) if you’re hosting non-off-grid Sims.
FAQ Section
Q1: Can I use regular toilets if I have rainwater collectors?
A: Yes! As long as your rainwater collectors have water, standard plumbing (toilets, sinks, showers) will function normally. The game treats rainwater the same as municipal supply for plumbing purposes.
Q2: Why do my Sims complain about dirty composting toilets?
A: Composting toilets require manual emptying every few uses. Click the toilet and select “Empty Compost” to avoid hygiene penalties.
Q3: Do dishwashers work off the grid?
A: Only if you have rainwater collectors with sufficient water. Eco dishwashers (like the “GreenClean”) are more efficient and recommended.
Q4: Can I go off-grid without the Eco Lifestyle Pack?
A: No. The “Off the Grid” utility option and all related fixtures (rainwater collectors, composting toilets) are exclusive to the Eco Lifestyle Expansion Pack.
Q5: Does weather affect rainwater collection?
A: Absolutely. Rainy days fill collectors faster. In dry climates or during drought events, collectors may not refill daily—plan accordingly.
Q6: How do I check if my lot is truly off the grid?
A: In Build Mode, open Lot Info > Utilities. If both Water and Power show “Off the Grid,” your lot is disconnected from municipal services.
Final Thoughts: Embrace Sustainable Sims Living
Understanding that “Sims 4 plumbing doesn’t work off the grid” without proper setup is the first step toward mastering eco-friendly gameplay. With rainwater collectors, composting toilets, and smart fixture choices, your Sims can live comfortably—completely independent of city utilities.
Not only does this add realism and challenge, but it also aligns with real-world sustainability trends. According to a 2023 Pew Research study, 68% of U.S. adults support renewable energy adoption—so your Sims are ahead of the curve!
