Both are McAlpine 90mm shallow traps with 70mm height, 50mm water seal, and 34L/min flow rate. The key difference is tray thickness compatibility and outlet type. The ST90CB10-70 (this product) suits tray thickness 0–23mm and has a Multifit outlet compatible with plastic, copper, and lead pipe. The ST90CPB-S-70 suits tray thickness 5–30mm and has a 1½" solvent weld outlet. Check your tray thickness and pipework type before ordering. What clearance does this trap require beneath the shower tray? The ST90CB10-70 has an overall height of 70mm and requires 70mm of clearance beneath the shower tray. Measure the available depth between the underside of your shower tray and the floor before ordering. If you have less than 70mm available, see the McAlpine ST90CPB-S-53 (53mm height). What tray thickness is this trap suitable for? The ST90CB10-70 is designed for shower trays with a thickness of 0–23mm. If your tray is between 5–30mm thick, the ST90CPB-S-70 may also be suitable — check the overlap range for your specific tray thickness. What is a Multifit connection? McAlpine’s Multifit connection is a versatile outlet system compatible with all plastic waste pipes to BS EN 1451-1 and BS EN 1329-1, as well as copper pipe (metric or imperial) and lead pipe. A moulded internal sleeve centres and supports the pipe, whilst Multifit and friction washers ensure a secure seal. The joint is completed hand-tight — no tools required. This makes the ST90CB10-70 compatible with a wider range of existing pipework than a standard solvent weld outlet. What is the water seal depth, and why does it matter? The water seal depth is 50mm. The water seal is the depth of water retained in the trap that prevents sewer gases from entering the bathroom. The minimum required by UK building regulations is 25mm. A 50mm seal provides significantly better odour protection and is less likely to evaporate in infrequently used showers. What flange finishes are available? The ST90CB10-70 is available with a white plastic, chrome plated plastic, or chrome plated brass 110mm removable flange. The flange sits over the waste hole on the tray surface and is removable for easy cleaning without disturbing the trap body. Is this trap BS EN 274 compliant? Yes — the McAlpine ST90CB10-70 is fully compliant with BS EN 274-1:2002 (requirements) and BS EN 274-2:2002 (test methods), the relevant British and European standard for sanitary waste fittings. 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.

McAlpine Shallow Shower Trap — 90mm — 53mm Height — 25mm Seal — ST90CPB-S-53 The McAlpine ST90CPB-S-53 is an ultra-low profile shallow shower trap engineered for installations where sub-floor clearance is severely restricted. At just 53mm overall height, it is one of the slimmest 90mm shower traps available whilst maintaining a 34 litre/min flow rate and full BS EN 274 compliance. The polypropylene body is supplied with a removable 110mm chrome plated brass flange and all fittings for a complete installation. Ideal for timber floor constructions, retrofit projects, and first-floor bathrooms with minimal joist depth. ⚠️ Check clearance before ordering. This trap requires 53mm of clearance beneath the shower tray. Confirm your sub-floor depth before purchasing. Note: this trap has a 25mm water seal — if you require a deeper 50mm seal for better odour protection, see the McAlpine ST90CPB-S-70 (70mm height, 50mm seal). Key Features 53mm overall height — one of the slimmest 90mm shower traps available; suits severely restricted sub-floor depths 25mm water seal — meets minimum UK building regulation requirement for odour protection 34 litres/min flow rate — high drainage performance; prevents water pooling 90mm waste hole — fits standard shower trays with 90mm waste apertures 1½" BSP thread — standard UK connection size Removable 110mm flange — chrome plated brass; easy cleaning and debris removal 1½" solvent weld outlet — secure, leak-free connection to waste pipe Complete installation kit — 135° bend, BSP coupling nut, and 1½" universal connector included BS EN 274 compliant — tested to BS EN 274-1:2002 and BS EN 274-2:2002 Technical Specification Brand: McAlpine Model: ST90CPB-S-53 SKU: ST90CPB-S-53 EAN: 5013512012530 Type: Shallow shower trap Waste hole diameter: 90mm Overall height: 53mm Under-tray clearance required: 53mm Water seal depth: 25mm Flow rate: 34 litres/min (tested under 15mm constant head, BS EN 274-2:2002) Thread size: 1½" BSP Outlet: 1½" solvent weld Flange diameter: 110mm (removable) Flange finish: Chrome plated brass Body material: Polypropylene Weight: 0.3kg Standards: BS EN 274-1:2002 & BS EN 274-2:2002 What’s Included McAlpine ST90CPB-S-53 shallow shower trap body 110mm chrome plated brass removable flange 135° bend BSP coupling nut 1½" universal connector Installation instructions Suitable For Installations with severely restricted sub-floor clearance (as little as 53mm) Timber floor constructions and first-floor bathrooms with minimal joist depth Retrofit shower installations in existing bathrooms Wet room conversions with shallow floor build-ups Apartment and flat renovations with concrete floors Any installation requiring a 90mm waste hole trap with minimal height Also Available — McAlpine Shallow Traps McAlpine ST90CPB-S-70 — 90mm Shallow Trap, 70mm Height, 50mm Water Seal — deeper seal for better odour protection where 70mm clearance is available Coordinate Your Shower Installation Shower Trays — browse compatible low profile trays Shower Enclosures — complete your shower installation Shower Valves & Accessories — valves, heads, and arms Frequently Asked Questions What clearance does this trap require beneath the shower tray? The McAlpine ST90CPB-S-53 has an overall height of 53mm and requires 53mm of clearance beneath the shower tray. This makes it one of the slimmest 90mm shower traps available and suitable for installations where even the ST90CPB-S-70 (70mm) would not fit. Measure the available depth between the underside of your shower tray and the floor before ordering. What is the difference between the ST90CPB-S-53 and the ST90CPB-S-70? Both are McAlpine 90mm shallow shower traps with the same 34L/min flow rate and BS EN 274 compliance. The key differences are height and water seal depth. The ST90CPB-S-53 (this product) is 53mm high with a 25mm water seal — the slimmest option, suitable for the most restricted installations. The ST90CPB-S-70 is 70mm high with a superior 50mm water seal — better odour protection, recommended where 70mm clearance is available. If you have the space, the ST90CPB-S-70 is the preferred choice for its deeper seal. What size waste hole does this trap fit? This trap is designed for shower trays with a 90mm waste hole and a 1½" BSP thread. This is the standard waste hole size for the majority of UK shower trays. Check your tray specification before ordering if you are unsure. What is the water seal depth? The water seal depth is 25mm — the minimum required by UK building regulations. The water seal is the depth of water retained in the trap that prevents sewer gases from entering the bathroom. If you have sufficient clearance (70mm), the ST90CPB-S-70 with its 50mm seal provides significantly better odour protection and is less likely to evaporate in infrequently used showers. What type of outlet connection does this trap use? The outlet is 1½" solvent weld, connecting to standard 40mm (1½") solvent weld waste pipe. A 135° bend, BSP coupling nut, and 1½" universal connector are included to allow flexible pipe routing beneath the tray. Is this trap BS EN 274 compliant? Yes — the McAlpine ST90CPB-S-53 is fully compliant with BS EN 274-1:2002 (requirements) and BS EN 274-2:2002 (test methods), the relevant British and European standard for sanitary waste fittings. Can I order if the item shows as out of stock? Yes — this product is available to order even when stock shows as zero.

The McAlpine Scale Defender Refill Pack contains 2 replacement polyphosphate cartridges for use with your existing McAlpine Scale Defender unit. Each cartridge treats up to 40,000 litres, providing continued limescale protection for your boiler, pipes, appliances, and entire home plumbing system. What's Included 2 x Replacement Cartridges - Food-grade polyphosphate dosing cartridges Each cartridge treats up to 40,000 litres Total capacity: 80,000 litres (both cartridges combined) Why Replace Your Cartridge? The polyphosphate cartridge is the active component that protects your home from limescale. As water passes through, the cartridge gradually dissolves, treating your water supply. When the cartridge is depleted, it needs replacing to maintain continuous limescale protection. Signs your cartridge needs replacing: Cartridge appears significantly smaller or depleted Limescale starting to reappear on taps or appliances Approximately 40,000 litres of water has passed through (varies by household usage) Reduced water treatment effectiveness Key Features 2 cartridges included - Long-term supply for continued protection 40,000 litres per cartridge - Extended treatment capacity Food-grade polyphosphate - Safe for drinking water (WHO & FAO approved) Easy DIY replacement - Simple screw-in installation, no plumber needed Compatible with all Scale Defender units Maintains system efficiency - Keeps your heating system running optimally Protects entire home - Boiler, pipes, radiators, taps, and appliances Saves money - Prevents costly limescale damage and reduces energy bills Technical Specifications Brand: McAlpine Product Type: Scale Defender Replacement Cartridges Quantity: 2 cartridges Cartridge Capacity: Up to 40,000 litres each Total Capacity: 80,000 litres (both cartridges) Weight: 0.41kg (pack of 2) Material: Food-grade polyphosphate Standards: BS EN 1212, EC regulations EN 1212 Compatibility: All McAlpine Scale Defender units SKU: K33101 Safety: WHO & FAO approved for drinking water How to Replace Your Cartridge Replacing your Scale Defender cartridge is quick and easy: Turn off your water supply Unscrew the Scale Defender housing Remove the old cartridge Insert the new cartridge Screw the housing back together Turn the water supply back on Check for leaks No plumber required - most homeowners can replace the cartridge themselves in just a few minutes. Why Continue Using Scale Defender? Limescale affects your pipework, boiler, radiators, taps, appliances, and fittings and can lead to increased repairs or early replacement costs. A 1mm layer of limescale in your boiler can amount to an extra £150 to £200 in household bills every year according to the Carbon Trust. By maintaining your Scale Defender with regular cartridge replacements, you continue to: Reduce energy bills by maintaining boiler efficiency Extend the life of your boiler and heating system Protect washing machines, dishwashers, and other appliances Prevent costly limescale-related repairs Maintain better water flow and pressure Keep taps and fixtures looking cleaner 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. Perfect For Existing Scale Defender unit owners Replacing depleted cartridges Maintaining continuous limescale protection Hard water areas Homes with combination boilers Properties with expensive heating systems Landlords maintaining rental properties Long-term system maintenance Note: This is a refill pack containing replacement cartridges only.

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.

Easy to Fit McAlpine Scale Defender should be fitted by a qualified plumber, but at between 45–60 minutes to fit, it should only be an hour's call out. The kit includes both 15mm and 22mm connectors for compatibility with standard UK copper pipe installations. Thereafter, it is easy to replace the cartridges, and the system requires no ongoing maintenance. Perfect For Hard water areas with limescale problems Protecting boilers and heating systems Extending appliance lifespan (washing machines, dishwashers, kettles) Reducing energy bills and improving efficiency New build installations Renovation projects Homes with expensive boiler systems Properties with combination boilers Landlords protecting rental property investments Cost Savings By preventing limescale build-up, the Scale Defender helps you save money in multiple ways: Reduced energy bills (limescale reduces boiler efficiency) Extended boiler lifespan (prevents scale damage) Fewer appliance repairs and replacements Reduced plumbing maintenance costs Better water flow and pressure Investment protection: At a fraction of the cost of boiler repairs or replacement, the Scale Defender pays for itself through energy savings and extended equipment life.

The McAlpine ST90CPB-S-70 has an overall height of 70mm and requires 70mm of clearance beneath the shower tray for the trap body. Measure the available depth between the underside of your shower tray and the floor (or top of the joist) before ordering. If you have less than 70mm available, you will need an ultra-low profile trap. What size waste hole does this trap fit? This trap is designed for shower trays with a 90mm waste hole and a 1½" BSP thread. This is the standard waste hole size for the majority of UK shower trays. Check your tray specification before ordering if you are unsure. What is the water seal depth, and why does it matter? The water seal depth is 50mm. The water seal is the depth of water retained in the trap that prevents sewer gases from entering the bathroom. The minimum required by UK building regulations is 25mm. A 50mm seal provides significantly better odour protection and is less likely to evaporate in infrequently used showers, making it the preferred choice for professional installations. What is the flow rate of this trap? The ST90CPB-S-70 has a tested flow rate of 34 litres per minute (tested under a 15mm constant head to BS EN 274-2:2002). This is a high flow rate for a shallow trap, ensuring rapid drainage and preventing water pooling even with power showers and high-flow shower heads. What type of outlet connection does this trap use? The outlet is 1½" solvent weld. This connects to standard 40mm (1½") solvent weld waste pipe. A 135° bend, BSP coupling nut, and 1½" universal connector are included to allow flexible pipe routing beneath the tray. Is this trap BS EN 274 compliant? Yes — the McAlpine ST90CPB-S-70 is fully compliant with BS EN 274-1:2002 (requirements) and BS EN 274-2:2002 (test methods). This is the relevant British and European standard for sanitary tapware and waste fittings, providing assurance of quality and performance. Can I order if the item shows as out of stock?
