Understanding the Basics: What is a Cistern?
A toilet cistern, often called a toilet tank, is the boxy part of a traditional toilet that sits behind or above the toilet bowl. Its main job is to hold a reservoir of water. When you flush, this stored water is released into the bowl to push waste away. It’s a simple, reliable mechanism that has been a standard in bathrooms for a long time. Think of it as the toilet’s personal water bottle, ready to deliver a powerful flush whenever you need it.
Inside the cistern, a few key parts work together: a float valve (or inlet valve) that refills the tank after flushing and stops water flow when full, and a flush valve (or outlet valve) controlled by your flush lever or button, which allows the water to exit. Understanding these components helps demystify the “installation of cistern vs alternative” decision.
The traditional cistern system is what most people picture when they think of a toilet. It’s a proven design that’s easy to understand and maintain. When considering the “installation of cistern vs alternative,” the cistern system is often the most familiar and straightforward for DIYers.
Traditional Cistern Toilet Installation: A Step-by-Step Guide
Installing a new cistern toilet might seem daunting, but with the right tools and a clear plan, it’s a very achievable DIY project. We’ll break down the process into manageable steps. Safety first, of course! Always turn off the water supply before you begin, and wear gloves.
What You’ll Need: Tools and Materials
Gathering your supplies beforehand makes the process much smoother. Here’s a list of common tools and materials you’ll likely need for a cistern toilet installation:
- New toilet (cistern and bowl)
- Toilet seat and lid
- Toilet spud washer (if not included)
- Toilet bolt caps (if not included)
- Wax ring (or wax-free alternative)
- Toilet flange bolts (or closet bolts)
- Adjustable wrench or pipe wrench
- Screwdriver set
- Putty knife or scraper
- Level
- Measuring tape
- Bucket
- Rags or old towels
- Gloves
- Safety glasses
- Plumber’s putty (optional, for sealing the base)
- Flexible toilet supply line
Step 1: Shut Off Water and Remove the Old Toilet
This is the most crucial first step for safety and to prevent floods. Locate the shut-off valve behind the toilet (usually on the wall or floor) and turn it clockwise until it stops. Flush the old toilet to empty as much water as possible from the cistern and bowl. Disconnect the water supply line from the cistern. Then, remove the nuts from the closet bolts at the base of the toilet. Gently rock the old toilet side-to-side to break the wax seal, then lift it straight up and away. Place it in a bucket or on old towels to catch any residual water.
Step 2: Prepare the Flange and Install New Bolts
Once the old toilet is out of the way, you’ll see the toilet flange, which is a circular fitting that connects the toilet to the drainpipe. Clean the area around the flange using a putty knife or scraper to remove any old wax. If your flange is damaged or loose, it needs to be repaired before proceeding. Insert the new closet bolts into the slots on the flange, ensuring they are positioned correctly to line up with the bolt holes on your new toilet’s base. Secure them with washers and nuts, but don’t overtighten them yet.
Step 3: Install the New Wax Ring and Position the Toilet
Take your new wax ring. Some come with an integrated plastic funnel that helps guide the ring and waste into the drainpipe. Place the wax ring directly onto the flange or onto the bottom of the new toilet bowl. Ensure it’s centered. Now, carefully lift the new toilet. Align the bolt holes on the toilet’s base with the closet bolts on the flange. Gently lower the toilet straight down onto the flange, making sure the wax ring creates a good seal. Press down firmly on the bowl to seat it properly.
Step 4: Secure the Toilet and Connect the Supply Line
Once the toilet is in place and sealed, snug down the nuts on the closet bolts. Use your wrench to tighten them evenly, alternating between the two bolts. Don’t overtighten, as this can crack the porcelain. Once the toilet is stable and level, reattach the new flexible toilet supply line. Connect one end to the inlet valve on the cistern and the other to the shut-off valve. Hand-tighten first, then use a wrench for a final quarter-turn. Avoid over-tightening, which can damage the fittings.
Step 5: Turn on Water and Test
Slowly turn the water shut-off valve counter-clockwise to restore the water supply. Open the valve all the way. Let the cistern fill. Once it’s full, check carefully for any leaks around the base of the toilet, the bolts, and the supply line connections. After the cistern fills, flush the toilet. Check that water flows properly and that there are no leaks during and after the flush. You might need to adjust the float valve inside the cistern to set the correct water level.
Cistern Toilet Installation vs. Alternatives: A Comparative Look
When discussing the “installation of cistern vs alternative,” it’s helpful to understand what makes them different and what their unique advantages and disadvantages are. While the traditional cistern is popular, modern plumbing offers innovative solutions.
Traditional Cistern Toilet
This is the classic setup we’ve just detailed. It’s a self-contained unit where the tank (cistern) is directly attached to the bowl.
Pros:
- Familiarity and Simplicity: Most people are comfortable with how they work.
- Easy Installation: Generally straightforward for DIYers, especially when replacing an existing toilet.
- Readily Available Parts: Replacement parts are abundant and inexpensive.
- Consistent Performance: Reliable flushing mechanism with a good amount of water.
- Cost-Effective: Often the most budget-friendly option upfront.
Cons:
- Space: Can take up more floor space due to the tank size.
- Water Usage: Older models can be less water-efficient, though modern dual-flush cisterns improve this.
- Aesthetics: Some find the tank design less sleek than modern alternatives.
Alternative Toilet Systems
These systems move away from the traditional, attached cistern design. They often prioritize space-saving, water efficiency, or different installation approaches.
1. Back-to-Wall Toilets (with Concealed Cistern)
In this setup, the cistern is hidden behind the wall or within a vanity unit. Only the toilet bowl is visible, creating a minimalist, modern look. The flush button is mounted on the wall or furniture.
Pros:
- Sleek Aesthetics: Very modern and clean appearance, as the cistern is hidden.
- Space-Saving: Can be very compact, especially wall-hung versions.
- Easier Cleaning: Fewer nooks and crannies around the toilet base.
- Customizable Height: Wall-hung options allow for adjustable mounting height.
Cons:
Installation Complexity: Requires more involved renovation for the concealed cistern and flush mechanism. This is a significant difference in “installation of cistern vs alternative” complexity.
- Access for Maintenance: Repairs to the cistern require access panels, which can be hidden behind tiles or panels.
- Higher Cost: Generally more expensive due to the concealed cistern, frame, and potentially more labor.
- Professional Installation Recommended: Often requires a plumber or builder for proper installation.
For a concealed cistern system, installation involves mounting a metal support frame, connecting the cistern to the frame and water supply, then tiling or cladding the access area. The toilet bowl is then attached to the frame or wall. This is a more intricate process than a standard cistern installation.
You can find great resources on concealed cistern systems from plumbing manufacturers like Geberit, which provides detailed technical information.
2. High-Level or Low-Level Cistern Toilets
This is a retro or vintage style where the cistern is mounted high on the wall (high-level) or at a medium height (low-level), connected to the bowl by a long flush pipe. The flush is usually operated by a pull chain for high-level cisterns.
Pros:
- Distinctive Style: Ideal for period or vintage bathrooms seeking an authentic look.
- Powerful Flush: The height of the cistern allows gravity to create a very strong flush.
- Can be Decorative: The cistern and pipework can become a design feature.
Cons:
- Space Requirements: High-level cisterns need significant vertical wall space.
- Complexity of Installation: Mounting the cistern securely high up and aligning the pipe can be challenging.
- Accessibility: Pull chains and high cisterns can be difficult for some users.
- Water Use: Often uses more water per flush than modern dual-flush toilets.
Installing a high-level cistern involves securely mounting the cistern bracket to wall studs, ensuring it can withstand the weight of a full tank of water. The flush pipe is then carefully aligned and connected to both the cistern outlet and the toilet bowl inlet.
3. Saniflo or Macerator Systems
These are not direct alternatives in terms of cistern type, but they offer a solution when a traditional drain connection isn’t feasible. A macerator unit grinds waste into a fine pulp, which can then be pumped through narrow pipes to a drain or sewage system.
A macerator system can be used with a standard toilet bowl and a small, sometimes integrated, cistern. The key difference is what happens after the flush to the waste.
Pros:
- Flexibility in Placement: Can install toilets in basements or areas without gravity drainage.
- Concealed Pipework: Uses small diameter pipes that can be hidden easily.
- Quieter Than Expected: Modern units are relatively quiet during maceration.
Cons:
- Requires Electricity: The macerator pump needs to be plugged in.
- Noise: While quieter than older models, the macerator does make noise during operation.
- Maintenance: Macerators can be prone to blockages if inappropriate items are flushed, and repairs can be costly.
- Not Suitable for All Waste: Cannot handle items like sanitary pads, wipes, or excessive toilet paper.
The installation of a macerator system involves connecting the toilet bowl to the macerator unit, ensuring a watertight seal. The macerator unit is then connected to the small cistern (if separate) and the pump outlet pipe. Electrical connection is also a critical part of the installation.
For more on macerator systems, resources like those from Saniflo can be very useful.
