FAQ
What should I check is included in the box before I start installing my new tap or mixer?
Typically, you’ll find the tap/mixer itself, a retaining nut, and possibly a small quantity of PTFE tape for sealing threads. However, it's wise to verify if washers, flexible connectors (if needed), and any mounting brackets are present; these often aren't included.
I've noticed my new tap leaks around the base – what could be causing this?
A common cause of leaks is insufficient or damaged PTFE tape on the threads during installation. Ensure you’ve used enough and that the tape isn’t frayed or contaminated, and check for any debris blocking the valve.
Do I need special tools to install a tap or mixer?
While some installations are straightforward with basic plumbing tools like adjustable spanners, you might find a basin wrench incredibly useful for tight spaces under sinks. A pipe sealant sleeve can also be helpful for creating a watertight seal.
What kind of waste connector do I need to connect my tap to the drain?
The type of waste connector depends on your sink configuration; you’ll likely need a ‘P-bend’ connector for a standard pedestal basin or a ‘S-bend’ for an inset unit, and consider the diameter required.
I'm replacing an old tap – do I still need the old retaining nut?
Yes, you almost certainly will. The new tap will require the retaining nut to secure it firmly to the sink basin; ensure you carefully remove it from the old tap before installation.
What is PTFE tape and why is it important?
PTFE (Teflon) tape is a thin, self-adhesive tape used to create a waterproof seal around threaded connections. It prevents water leakage by filling in imperfections on the threads, ensuring a tight fit.
Should I use plumbers sealant alongside PTFE tape?
While PTFE tape primarily seals threads, applying a small amount of plumber's sealant to the rubber washers can create an extra layer of protection against leaks and improve the seal’s longevity.
What if my flexible connectors are too short?
Measure carefully before purchasing longer flexible connectors; you’ll need enough length to reach between the tap outlet, the basin, and the waste pipe, allowing for some slack.
How do I prevent damage during installation?
Protect your sink surface with a protective cloth or cardboard when using tools. Work slowly and carefully, avoiding excessive force on any components – this can easily strip threads.
What should I do if the tap won’t tighten properly?
If you're struggling to tighten the retaining nut, double-check that the sink basin is clean and free of debris. Ensure you are using the correct size spanner and applying even pressure – excessive force can damage the threads.
In depth
Maintaining plumbing systems requires more than just the initial installation of taps and fixtures. Alongside the core product, a range of ongoing consumables and accessories are frequently needed to ensure smooth operation and prevent issues developing over time. These often get overlooked in the initial purchase but become essential for efficient and reliable performance.
Firstly, consider water treatment solutions. Even with hard water systems, regular filtration can significantly improve appliance longevity and reduce limescale build-up within the taps themselves. This might involve purchasing replacement filter cartridges – the frequency of these will vary depending on water hardness and usage – or investing in a whole-house water softener system if particularly problematic. Similarly, scale inhibitors designed for plumbing systems can be beneficial, though careful consideration should be given to their compatibility with existing materials.
Then there’s the realm of maintenance tools and supplies. A good set of pipe wrenches, basin wrenches, and adjustable spanners is non-negotiable for any homeowner undertaking repairs or adjustments. Beyond these, you'll need plumbers tape – essential for sealing threaded connections and preventing leaks – threadlock compound to reinforce joints, and various sizes of Teflon tape for similar applications. Don’t forget a small supply of penetrating oil; this can be invaluable when dealing with stubborn fittings.
Cleaning supplies are also crucial, though often underestimated. Dedicated limescale cleaners formulated specifically for plumbing systems will effectively remove mineral deposits from taps and showerheads, preventing blockages and maintaining water flow. Similarly, stainless steel polishes are useful for keeping the finished look of fixtures pristine. Having a supply of microfiber cloths for cleaning is also recommended to avoid scratching surfaces.
Beyond immediate maintenance, preventative measures can greatly reduce future problems. Regularly flushing tap aerators – these accumulate debris that restricts water flow – is a simple yet effective task. Inspecting and replacing washers within taps and valves is another vital routine, as worn components are a common cause of leaks. Keeping a supply of replacement washers in various sizes ensures you’re prepared for any unexpected issues.
Finally, consider the long-term durability of your plumbing system. Protective coatings designed to resist corrosion and chemical attack can extend the lifespan of taps and fixtures, particularly in areas with aggressive water chemistry. While this represents an upfront investment, it can ultimately save money on replacement costs down the line. Maintaining a well-stocked toolkit and proactively addressing minor issues will invariably contribute to a more reliable and trouble-free plumbing system.
