Cartridge Types Explained
Ceramic Disc Cartridges (Quarter-Turn): Modern tap mechanism that operates with a 90° turn from off to full flow. Two ceramic discs slide over each other to control water flow. These are found in most contemporary taps manufactured from the 1990s onwards. Durable, reliable, and provide smooth, drip-free operation.
Full-Turn Cartridges (Traditional): Classic tap mechanism requiring multiple turns to open and close. These use rubber washers or seals and are found in traditional taps and older installations. The UC series covers the most common full-turn cartridge sizes and configurations.
How to Use the Cartridge Finder Tool
The included cartridge finder tool allows you to quickly identify the correct replacement cartridge without removing the old one. Simply measure the cartridge dimensions using the finder tool, match to the reference chart, and select the corresponding cartridge from your kit. This saves time on-site and ensures first-time-right replacements.
Applications & Use Cases
Perfect for professional plumbers, maintenance engineers, property managers, landlords with multiple properties, facilities management teams, hotels, care homes, schools, commercial buildings, and anyone responsible for maintaining multiple taps. The comprehensive range ensures you can handle most tap repair jobs without return trips for parts.
Why Choose This Kit?
Instead of purchasing individual cartridges at £5-£15 each (which would cost £230-£690 for this quantity), this kit provides exceptional value at £149. The organized storage system keeps cartridges protected and easily identifiable, while the refillable box design means you can replenish individual types as they're used. The FREE cartridge finder tool alone is worth £15-£20.
Refilling & Maintenance
The storage box is designed for long-term use. As you use cartridges from the kit, simply order individual replacement cartridges to refill the specific compartments. The labelling system ensures you always know which cartridge types need replenishing. This makes the kit a sustainable, long-term solution for tap maintenance.
Compatibility
These cartridges are compatible with most major tap brands including Bristan, Grohe, Hansgrohe, Ideal Standard, Armitage Shanks, Crosswater, Vado, and many others. The comprehensive range covers approximately 85-90% of common tap cartridge requirements in UK properties. Always check your existing cartridge type before installation.
Installation Tips
Always turn off water supply before replacing cartridges. Note the orientation of the old cartridge (hot/cold marking). Clean the cartridge housing before installing the new cartridge. Hand-tighten only - do not over-tighten as this can damage the brass threads. Test for leaks before fully reassembling the tap.

Classi Seal Waterproofing Strip — Sold Per Metre — Self-Adhesive — 15mm Movement
The Classi Seal Waterproofing Strip is a professional self-adhesive tanking strip designed to create a reliable secondary waterproof seal between shower trays or baths and bathroom walls. Applied before installation, it creates a flexible membrane behind the tiles that accommodates up to 15mm of building movement — providing far superior long-term protection compared to silicone sealant alone. Sold per metre, cut fresh from a 25m roll, so you order exactly what you need with no waste.
📏 Sold per metre — enter the quantity in metres at checkout.Quantity 3 = 3 metres (£36) · Quantity 5 = 5 metres (£60) · Quantity 10 = 10 metres (£120)How much do you need? Standard shower tray or bath (3 sides): approx. 3–3.5m · Large enclosure: 4–5m · Add 10% for trimming.
Key Features
Sold per metre — cut to your exact length from a 25m roll; no waste
Self-adhesive backing — pressure-sensitive; quick, clean installation
15mm movement accommodation — flexes with building settlement without compromising the seal
Tile immediately — no curing time required after application
Superior to silicone alone — creates a waterproof membrane behind the tiles
Flexible strip — conforms to shower tray and bath edges
Technical Specification
Brand: Classi
SKU: CS025
Type: Self-adhesive flexible waterproofing tanking strip
Sold: Per metre (cut from 25m roll)
Width: 100–120mm (upstand + base)
Weight: 0.15kg per metre
Movement accommodation: Up to 15mm
Adhesive: Pressure-sensitive self-adhesive backing

Frequently Asked Questions
How do I order the right length?
Enter the number of metres you need as the quantity at checkout. For example, quantity 3 = 3 metres (£36), quantity 5 = 5 metres (£60). We cut your exact length fresh from a 25m roll. As a guide: a standard shower tray or bath on 3 sides requires approximately 3–3.5 metres. Add 10% for trimming. If in doubt, order slightly more — offcuts can be used for future repairs or smaller projects.
Why use a tanking strip instead of silicone alone?
Silicone sealant is the first line of defence but has limitations — building movement, settlement, and thermal expansion can cause silicone to crack or separate over time. Classi Seal provides a critical secondary barrier: a flexible waterproof membrane behind the tiles that accommodates up to 15mm of movement without failing. Even if the silicone joint cracks, the tanking strip prevents water from reaching the substrate. This dual-layer approach is considered best practice by professional bathroom installers and helps meet UK Building Regulations Part C requirements for wet areas.
Can I tile immediately after applying Classi Seal?
Yes — one of the key advantages of Classi Seal is that no curing time is required. Once the strip is applied and the tray or bath is positioned, you can tile over the upstand immediately. The base edge should be sealed with neutral cure silicone once tiling is complete.
What type of silicone should I use with Classi Seal?
Always use neutral cure silicone (not acetic/vinegar cure). Acetic cure silicone releases acetic acid during curing, which can damage the adhesive and membrane of the strip. Neutral cure silicone is widely available and is the correct choice for use with tanking strips and most bathroom materials.
What surfaces is Classi Seal suitable for?
Classi Seal is suitable for clean, dry, dust-free surfaces. Ensure the edges of the shower tray or bath are free from grease, dust, and moisture before application. Apply in temperatures between 5°C and 35°C for best adhesion.
Is there a pre-cut version available?
Yes — if you need a standard length for a single installation, a pre-cut 3.2m version is also available. The per-metre option (this product) is ideal when you need a specific custom length, are completing multiple bathrooms, or want to avoid waste from a pre-cut length that may not suit your installation.
Can I order if the item shows as out of stock?
Yes — this product is available to order even when stock shows as zero. Please allow additional lead time and contact us on 01603 381095 to confirm availability.

How It Works
The Scale Defender uses food-grade polyphosphate to treat your water supply. As water passes through the unit, the polyphosphate creates a protective coating on pipes and heating elements, preventing limescale from forming and gradually removing existing scale deposits. This keeps your system running efficiently and protects all downstream appliances and fittings.
What is Polyphosphate?
Polyphosphate is a food-grade (consumable) product approved by the World Health Organization and Food and Agricultural Organization. It is widely used today in the food processing industry for cheese, meat, wine, and other products.
McAlpine Scale Defender technology is a completely safe way to treat water in the home and is safe for human consumption according to WHO and FAO recommendations and in accordance with international norms for drinking water to EC regulations, standard EN 1212 and British Standard BS EN 1212.

Ideal for Hard Water – Essential protection in hard water areas
How Electrolytic Technology Works
The KeyPlumb electrolytic scale reducer uses proven electrolytic technology to alter the structure of limescale minerals in your water supply. As water passes through the unit, the electrolytic process prevents calcium and magnesium from forming hard scale deposits on surfaces. Instead, the minerals remain suspended in the water, passing harmlessly through your system without adhering to pipes, heating elements or appliances.
This process occurs naturally without chemicals, electricity or any external power source. The electrolytic reaction is triggered by the water flow itself, making it a completely passive, maintenance-free system.
Why Choose Electrolytic Over Traditional Water Softeners?
Unlike traditional water softeners, electrolytic scale reducers offer several key advantages:
No Salt Required: Traditional softeners need regular salt top-ups; electrolytic systems need nothing
Maintains Minerals: Keeps beneficial calcium and magnesium in your water
No Waste Water: Softeners discharge brine; electrolytic systems have zero waste
No Running Costs: No salt, electricity, or filter replacements
Compact Size: Fits inline with pipework; no bulky tank required
Better for Drinking: Maintains natural water taste and mineral content
Environmentally Friendly: No chemicals or salt discharge into drains

Frequently Asked Questions
What is the difference between the WC-CON8 and the WC-CON8E?
The WC-CON8E has an extended inlet for additional reach between the pan spigot and the soil pipe. If you need extra length, choose the WC-CON8E. For a standard 90° connection, the WC-CON8 is the right choice.
What does the double seal do?
The double seal on the pan connection creates a more secure, leak-free joint between the connector and the WC pan spigot — reducing the risk of seepage even with minor misalignment during installation.
What pan spigot sizes does this fit?
The adjustable inlet fits all standard WC pan spigots in the 97–107mm range, covering the vast majority of UK toilet pans.
What soil pipe does the outlet connect to?
The 110mm outlet is available with a finned end (for 4″/110mm PVC-U and cast iron soil pipe internal diameters) or a plain end (for 110mm soil or underground pipe fittings). Please confirm which outlet type you require before ordering.

Frequently Asked Questions
When should I use a straight connector rather than a 90° bent connector?
Use a straight connector like the WC-CON2 when the WC pan spigot and the soil pipe entry point are directly in line — i.e. the pan faces straight into the wall. If the soil pipe is offset to the side, you’ll need a 90° connector such as the WC-CON8 or WC-CON8E.
What pan spigot sizes does this fit?
The adjustable inlet fits all standard WC pan spigots in the 97–107mm range, covering the vast majority of UK toilet pans.
What soil pipe does the outlet connect to?
The standard 110mm outlet is available with a finned end (for 4″/110mm PVC-U and cast iron soil pipe internal diameters) or a plain end (for 110mm soil or underground pipe fittings). A 3½″/90mm finned outlet version is also available for older soil pipe systems.
Is this a rigid or flexible connector?
This is a rigid connector. If you need a flexible connector for awkward or offset installations, see our McAlpine F26R or McAlpine F33R flexible connectors.

What pan spigot sizes does this fit?
The adjustable inlet fits all standard WC pan spigots in the 97–107mm range, covering the vast majority of UK toilet pans.
What soil pipe does the outlet connect to?
The 110mm outlet fits the inside diameter of 4″/110mm PVC-U and cast iron soil pipe — the standard soil pipe size used in UK domestic installations.

Not all isolation valves are the same — and this one is specified for a reason. The KeyPlumb 15mm Flat Face Compression x ½" BSP Isolation Valve is the correct valve for installations where a basin mono tap with a flexi tail connects to a 15mm copper supply pipe. The flat face compression end grips the pipe without an olive, while the ½" male BSP thread connects directly to the flexi tail. A flathead screwdriver closes it off in a quarter-turn. Chrome-plated brass, neat, and built to last behind a basin pedestal for years.
Key Features
Flat Face Compression Inlet — 15mm flat face compression fitting; connects to copper pipe without a traditional olive; provides a secure, leak-proof seal
½" BSP Male Thread Outlet — standard ½" male BSP thread; connects directly to flexi tails on basin mono taps, kitchen taps, and similar fixtures
Screwdriver Slot Operation — quarter-turn flathead screwdriver; tamper-resistant and compact for tight under-basin spaces
Chrome-Plated Brass Body — corrosion-resistant construction with a polished chrome finish; professional appearance for exposed installations
Isolates Individual Fixtures — allows a tap or fixture to be isolated for maintenance without shutting off the water supply to the whole property
Hot & Cold Water — suitable for both hot and cold water supply lines
1-Year Manufacturer’s Guarantee — backed by KeyPlumb warranty
When to Use This Valve
This valve is specifically designed for installations where:
A basin mono tap (single lever, one tap hole) is being fitted with a flexi tail connection
The supply pipe is 15mm copper and the tap tail is ½" BSP (the UK standard)
A flat face compression fitting is required rather than a standard olive-and-nut compression
If your installation uses a standard CxC compression connection (no BSP thread), see our Straight Chrome Isolation Valve or Full Bore Isolation Valve instead.

Frequently Asked Questions
What is a flat face compression fitting?
A flat face compression fitting connects to the pipe using a flat sealing face rather than a traditional olive (ferrule). The pipe end is inserted and the nut is tightened, compressing the flat face against the pipe to create a watertight seal. It is commonly used in isolation valves where a BSP thread outlet is also required, such as this valve for basin mono tap installations.
Can I order if the item shows as out of stock?
Yes — we can fulfil this product even when stock shows as zero. Place your order as normal and we’ll confirm lead time with you.
What is the difference between this valve and a standard CxC isolation valve?
A standard CxC (compression-to-compression) isolation valve has compression fittings on both ends and is used to isolate a section of pipe. This valve has a flat face compression inlet on one end and a ½" BSP male thread on the other — making it specifically designed to connect a 15mm supply pipe directly to a flexi tail on a basin tap. If you don’t need a BSP thread outlet, use the straight CxC isolation valve instead.
Will this fit my basin mono tap flexi tail?
Yes — provided your flexi tail has a standard ½" BSP female connection (the UK standard for basin mono taps), this valve will connect directly. Check your tap’s flexi tail specification if unsure.
Is this valve WRAS approved?
This valve carries a 1-year manufacturer’s guarantee and is suitable for domestic hot and cold water supply. If you specifically require a WRAS-approved valve, please see our WRAS Approved Straight Isolation Valve or WRAS Approved Full Bore Isolation Valve.
Can this be used on a hot water supply?
Yes — this valve is suitable for both hot and cold water supply lines in standard domestic plumbing applications.
