September 19, 2024Is your toilet cistern constantly leaking or struggling to flush properly? These are clear signs that it’s time for a replacement. If you’re not interested in calling a toilet repair service, it’s best to address the issue as soon as possible.
But don’t worry, replacing a toilet cistern isn’t as complicated as the entire parts! In this post, we’ll walk you through the easy steps to replace a toilet cistern only, saving you time, money, and future headaches.
Ready to get started? Let’s dive in!
What Should You Prepare Before Replacing a Toilet Cistern?
So, what is cistern exactly? It’s the water tank located behind your toilet that stores the water needed for flushing. When you press the flush button or pull the lever, the cistern releases water into the bowl, clearing away waste.
Now, if your toilet is not flushing properly, the cistern could be the culprit. A malfunctioning cistern can lead to weak flushes or no flush at all, which is why it’s important to keep an eye on it and replace it when necessary.
Here’s what you’ll need for a smooth toilet cistern replacement:
- An adjustable wrench
- A screwdriver
- A sponge or towel (to soak up any water)
- A bucket (for excess water)
- A new toilet cistern
How to Replace a Toilet Cistern in 5 Steps
Follow these simple steps, and you’ll know exactly how to change a toilet cistern in no time.
1. Turn off the water to the toilet
The first and most important step is to shut off the water supply. Look for the isolation valve, usually located under the toilet.
Once you’ve found it, turn it clockwise until it’s fully closed. This will prevent any water from flowing while you work.
2. Drain the old cistern
Now, flush the toilet to drain as much water as possible from the cistern.
There may still be a small amount of water left at the bottom that didn’t flush. No worries! Grab an old towel or a sponge to soak up the remaining water.
You want the cistern completely empty before you start removing it. Trust me, nothing’s worse than having water splash all over your feet mid-job.
Tip: Some cisterns have a water outlet on the side, so double-check to ensure no water remains trapped there.
3. Remove the old cistern
With the water drained, it’s time to get hands-on. You’ll need an adjustable wrench or a spanner to loosen the bolts that secure the cistern to both the wall and the toilet bowl.
These bolts might be a bit stiff, especially if they’ve been in place for years, so don’t be afraid to apply some elbow grease.
Once the bolts are loosened, gently lift the cistern off the toilet. It may be slightly heavier than you expect, so make sure you have a good grip. Place the old cistern aside in a safe spot – it’s time to say goodbye!
Be cautious of any remaining water in the pipe connections as you lift the cistern off. Place a towel or bucket beneath to catch any drips.
4. Install the new cistern
Before installing your new cistern, check if your toilet setup is compatible with your new cistern type.
There are a few variations: close-coupled cisterns (where the cistern is mounted directly on the toilet), back-to-wall cisterns (which are hidden behind a wall or furniture), and low-level cisterns (mounted higher up on the wall with a visible pipe).
Make sure you’re working with the right kind!
Now, place the new cistern in position. Align it with the holes on the toilet bowl and the wall. It’s essential to line everything up correctly so that the water flows smoothly once reconnected.
Use your wrench to tighten the bolts. You want the cistern to be secure, but don’t over-tighten – you don’t want to crack your shiny new fixture!
5. Reconnect the water supply
Next, it’s time to reconnect the water supply. First, attach the water inlet pipe to the new cistern. Make sure the connection is snug but not overly tight to avoid damaging the threads.
Once connected, turn the isolation valve back on by turning it counterclockwise. You’ll start to hear the cistern filling up with water—always a good sign!
As the cistern fills, keep an eye out for leaks. Check around the base of the cistern and along the water inlet pipe. If you notice any drips, tighten the connections a bit more.
When is the Right Time to Replace Your Toilet Cistern?
Typically, a cistern lasts around 10 to 15 years, but there are a few signs that might indicate it’s time for a replacement sooner. If you’re noticing constant leaks, difficulty flushing, or strange noises coming from the cistern, it could be time to take action.
Another sign is if the cistern takes too long to refill after each flush, or if water continues running even when the tank should be full. These problems can increase your water bills and point to an ageing or malfunctioning unit.
If you’re facing any of these issues and wondering how to replace a toilet cistern, it’s better to act sooner rather than later. A timely replacement can prevent more serious plumbing problems down the road!
