Upgrading Old Cistern: Why You Should Do It

Old cisterns often cause frustration because they don’t work as well as they used to. You might notice that your toilet runs constantly or flushes weakly, which wastes water and increases your bills. Upgrading your cistern means you get a system designed with modern technology that uses less water but still flushes powerfully. 

These cisterns have two flushes, one for liquid waste and one for solid waste. This easy change can cut the water usage in half. Plus, newer cisterns operate quietly and reliably, so you won’t have to deal with annoying noises or constant repairs.

From my own experience running All Needs Plumbing, I recall a local café that frequently called us for cistern repairs. After upgrading their old cisterns to modern dual-flush models, they told me their water bills dropped noticeably and the toilets stopped making noise. That’s the kind of practical improvement every home or business can appreciate.

How to Know When It’s Time to Upgrade

Here are some clear signs that your cistern needs an upgrade:

Your cistern runs constantly or refills too often

This usually means there’s a leak or a faulty valve inside. It wastes water and can damage your bathroom floor.

The flush is weak or incomplete.

If your toilet doesn’t clear waste properly, an old or damaged cistern may prevent it from generating enough water pressure.

You hear loud noises while refilling.

Constant banging or hissing sounds are signs that the internal parts are worn out or not working correctly.

You spot cracks or corrosion on the cistern

Visible damage means your cistern is at risk of leaking or breaking down.

Your water bills have spiked without reason.

A faulty cistern can waste hundreds of litres of water daily, which adds up quickly.

Replacement parts for your model are hard to find

Older models may no longer be supported, making repairs difficult and expensive.

If you notice any of these, it’s best to call a professional plumber to assess the situation before it gets worse.

Benefits of Upgrading Your Cistern

Upgrading your cistern is more than just fixing a problem — it’s an investment in your home or business. Here’s what you gain:

Save water and reduce bills

Modern cisterns utilise advanced flushing technology that reduces water usage without compromising performance. Dual-flush systems let you choose the amount of water used per flush, which can save thousands of litres annually.

Enjoy quieter operation

Newer cisterns have better insulation and improved mechanisms that reduce noise when refilling or flushing. This is very important in places like businesses and homes where noise can be annoying.

Avoid constant repairs and leaks.

Old cisterns often need frequent fixes that add up in cost and inconvenience. A new cistern reduces the risk of leaks and breakdowns.

Get a sleek, modern look.

Today’s cisterns come in stylish designs that complement any bathroom décor. Some options are concealed or wall-hung for a cleaner look.

Comply with the current plumbing standards.

Plumbing regulations evolve, and newer cisterns meet these updated standards, helping you avoid compliance issues.

Increase property value

Upgrading your bathroom fixtures can improve your property’s appeal and boost its resale value.

What Happens During a Cistern Upgrade?

When you book an upgrade with us, here’s what you can expect:

Initial inspection

Our plumber visits your property to check your existing cistern, toilet type, and plumbing setup. We identify any issues and recommend the best replacement options.

Choosing the right cistern

We help you select a cistern that fits your toilet and water usage needs, whether it’s a dual-flush, pressure-assisted, or concealed cistern.

Installation

We carefully remove the old cistern, install the new one, and ensure that all the connections are safe. Then, we test the flush and refill mechanisms to confirm that everything works perfectly.

Cleanup

We leave your bathroom tidy and functioning smoothly, so you don’t have to worry about any mess or disruption.

Most upgrades take just a few hours, and we work efficiently to minimise any inconvenience.

Pro-Tip: If your cistern is noisy, try adjusting the float arm or replacing the washer. These minor tweaks can temporarily stop annoying sounds, but if the noise persists, it’s best to have a plumber check it out to avoid bigger problems.

Choosing the Right Replacement Cistern

Not all cisterns are compatible with every toilet or plumbing system. Here’s what to consider when picking a replacement:

Toilet compatibility

Some toilets require specific types or sizes of cisterns. We make sure your new cistern fits perfectly.

Water efficiency

Dual-flush cisterns are great for saving water, but some commercial settings might benefit from pressure-assisted models for stronger flushes.

Budget

We offer options at various price points without compromising on quality.

Warranty and durability

We install cisterns from trusted brands with solid warranties so you get peace of mind.

We guide you through these choices to find the best fit for your home or business.

Pro-Tip: Inspect your cistern’s internal parts every six months. Look for leaks, worn washers, or mineral buildup. Finding problems early can help you avoid paying a lot for repairs or replacing the whole thing later.

What Do You Do With an Old Cistern?

When we upgrade your cistern, we don’t just leave the old one behind. We remove it carefully and dispose of it responsibly. If parts can be recycled or reused, we ensure that they are, to reduce environmental waste. You don’t need to worry about the mess or where to take the old cistern — we handle it all for you.

Cost Considerations

Upgrading your cistern might seem like a significant expense, but it pays off quickly. Consider:

Lower water bills

Efficient cisterns use less water, saving you money every month.

Fewer repairs

New cisterns reduce the need for costly callouts and part replacements.

Increased property value

Updated bathrooms attract buyers and tenants.

Professional installation

Avoid DIY risks that can cause leaks or damage, as they can be costly in the long run.

Our quotes are clear and have no hidden fees, so you can trust them to help you make a budget.

FAQs About Upgrading Old Cistern

What do you do with an old cistern?

We will safely remove your old cistern and dispose of it in an environmentally friendly way. Recycling parts helps reduce landfill waste.

Can you just replace a cistern on a toilet?

Yes, you can often replace just the cistern without replacing the entire toilet. However, we check compatibility to make sure the new cistern fits and works properly.

How long should a toilet cistern last?

Most cisterns last between 10 and 15 years, depending on use and maintenance. If yours is old or showing signs of wear, it's best to get a new one.

Is it worth replacing an old toilet?

If the toilet bowl or pan is damaged or outdated, replacing the whole unit might be better. Otherwise, upgrading just the cistern is usually enough to improve performance and efficiency.

How to seal an old cistern?

Temporary fixes, such as waterproof tape or sealant, can temporarily stop minor leaks, but they are not long-term solutions. The best way to ensure a long-lasting seal is through professional repair or replacement.
