FAQ
I’ve measured my bathroom sink and bought a tap – it’s too small! What should I do?
Before purchasing, double-check the minimum hole size specified by the tap manufacturer; many taps require a 35mm or 40mm bore. Measure your existing tap hole accurately with digital calipers to ensure compatibility before committing to a purchase.
I bought a mixer tap that has lots of fancy features I don’t need – is it worth paying extra for?
Carefully consider which features you genuinely require and will use regularly; overly complex designs often add unnecessary cost without providing significant benefit. Focus on essential functions like temperature control and flow rate when selecting a mixer.
The tap arrived, but I’m missing all the bits to fit it! What am I supposed to do?
Check the packaging thoroughly for all included components – most taps come with gaskets, washers, and fitting instructions. If parts are missing, contact the manufacturer directly as per their warranty terms.
I've bought a new tap but need to buy flexible hoses too – how much should I expect to pay?
Flexible hoses can add significantly to the overall cost; budget approximately £15-£30 for a decent set of two, depending on material and length. Ensure they’re compatible with your tap's connection sizes (usually 1/2 inch or 3/4 inch).
My old tap was a simple one-handle design, but the new mixer tap has three handles – is this necessary?
Consider whether you actually need multiple controls; a single-lever mixer tap often offers sufficient functionality for most users. Evaluate your personal preferences and water flow control needs before investing in a more complex model.
I’m installing a new tap myself, but I've realised I need some basin waste connectors – where can I get these?
You’ll likely require various connectors for your specific sink setup; these are commonly available separately on sites like Amazon UK and specialist plumbing suppliers. Ensure you select the correct size and type to match your sink outlet.
I've bought a chrome tap, but it looks dull after a few weeks – is this normal?
Chrome taps can develop a slight haze over time due to water hardness; regular cleaning with a limescale remover will help maintain their shine. Consider purchasing a polishing cloth specifically designed for chrome finishes.
I’ve purchased a pull-out spray head mixer tap, but it doesn't work properly – what could be the problem?
Check that the hose is fully extended and locked into position; ensure there are no kinks or obstructions within the hose itself. Refer to the manufacturer’s instructions for troubleshooting specific issues.
I’m installing a new tap in a downstairs bathroom, should I consider the water pressure when selecting a model?
Low-pressure systems can struggle with high-flow taps; select a tap specifically designed for lower water pressures to avoid reduced performance and potential splashing. Check the manufacturer's specifications regarding minimum water pressure requirements.
I’m unsure about the thread size on my existing plumbing – what should I check?
Confirm the connection sizes (usually 1/2 inch or 3/4 inch) before purchasing a new tap; using incompatible threads will require adapters, adding to the overall cost and potential complications. Accurate measurement is key to a successful installation.

Measuring Up: The Space is Crucial
It’s easy to get swept up in the aesthetics of a tap – the finish, the lever style, perhaps even the fancy digital controls – but overlooking the physical dimensions of the space it will occupy is a common mistake. UK kitchens, particularly older ones, often have surprisingly tight spaces beneath sinks. A statement, oversized mixer tap with a substantial spout and a long lever won't just look out of place; it’s likely to be a frustrating fit. Before you even consider the design, meticulously measure the available space – not just the width, but also the height and depth. Pay particular attention to clearances around the base of the sink and any adjacent plumbing. Don’t assume that because your current tap fits, a similar one will. Tap manufacturers vary significantly in their designs, and even within a range, there can be considerable differences in spout length and lever reach. If you're replacing an existing tap, take accurate measurements of its dimensions before beginning your search. Consider the overall style of your kitchen – a sleek, modern mixer tap might look fantastic with minimalist cabinetry but completely clash with a traditional farmhouse design. Think about how much space is needed for water to flow freely without splashing or obstructing access to the drain.
Ignoring Operational Costs: Beyond the Initial Purchase Price
The initial purchase price of a tap is undoubtedly important, but it's crucial not to focus solely on that figure and neglect to consider the ongoing running costs. Many taps, particularly those with advanced features like temperature monitoring or hands-free operation, require electricity to function. A mixer tap with a built-in digital display will draw power constantly, even when you’re not actively using it. This translates into an increase in your energy bill over time. Similarly, some high-pressure taps may have electric pumps that consume energy – again, contributing to increased running costs. Before committing to a complex or feature-rich tap, investigate the electricity consumption and potential long-term operational expenses. Consider whether you truly need all of the features offered. A simple, reliable tap with a good quality ceramic valve will likely be more cost-effective in the long run than a sophisticated model that you rarely use fully. Factor in the potential costs of repairs or replacements too – complex mechanisms are often more expensive to fix and may have shorter lifespans.
The Siren Call of ‘Special Features’: Do You Really Need Them?
Tap manufacturers frequently highlight “innovative” features designed to enhance convenience and performance. However, many of these additions are purely marketing ploys and offer little practical benefit for the average homeowner. A tap with a hands-free operation might be appealing in theory, but it’s rarely used regularly and can be prone to failure if not properly maintained. Similarly, taps with integrated water filters require regular cartridge replacement, adding an ongoing cost to your maintenance budget. Temperature monitoring systems, while useful for precise control, often add unnecessary complexity and expense. Before being swayed by a headline feature, honestly assess whether you’ll actually use it regularly. A simple tap with a good quality ceramic valve is perfectly capable of delivering excellent water flow and temperature control – without the added cost and potential maintenance headaches associated with overly complex designs. Don't be blinded by bells and whistles; focus on the core functionality that matters to you.
Overlooking Plumbing Compatibility: The Foundation Matters
Selecting a tap doesn’t begin and end with its aesthetic appearance or feature set. It’s absolutely essential to ensure compatibility with your existing plumbing setup. Tap connections come in various sizes, and using the wrong size can lead to leaks, damage to pipes, and costly repairs. Take accurate measurements of your existing supply pipe diameter – this is typically 32mm or 38mm for hot and cold water. Ensure that the new tap’s connection fittings are compatible with these dimensions. If you're replacing an older tap with a significantly different design, you may need to upgrade your plumbing as well, adding considerably to the overall cost. Consider the type of piping used in your kitchen – copper, PVC, or metal. The tap’s fitting should be compatible with the existing material. If you’re unsure about any aspect of the plumbing compatibility, consult a qualified plumber before making a purchase. It's far better to invest a little time and money upfront to ensure a proper fit than to face costly repairs later on.
Letting Spec Sheets Dictate Decisions: Beyond the Numbers
Tap manufacturers often provide detailed technical specifications – spout length, flow rate, pressure ratings, etc. – but these figures can be misleading if you don’t understand their significance. A high flow rate might sound impressive, but it could also lead to excessive water wastage and a higher energy bill for heating the water. Similarly, a high-pressure rating doesn't necessarily translate into better performance; the actual pressure experienced at the tap will depend on factors such as water pressure in your building and the tap’s internal design. Don't simply focus on these numbers – consider how they relate to your specific needs and usage patterns. A low-flow tap might be perfectly adequate for everyday tasks, while a high-flow tap could be overkill if you only ever use it for rinsing dishes. Prioritize quality and reliability over impressive specifications. Research reputable brands known for their durable components and efficient designs. Focus on the overall design and functionality of the tap rather than getting caught up in technical jargon.
