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.

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 AA10 is a self-ventilating resealing bottle trap — designed for basin and sink installations where secondary ventilation isn't practical. When syphonic conditions occur, the automatic hydraulic action draws air through the bypass columns to break the syphon; once conditions normalise, remaining water falls back to reseal the trap. No mechanical parts, no secondary vent pipe required. Key Features 75mm water seal — superior odour protection; deeper than the standard 50mm seal Self-ventilating / resealing design — eliminates the need for secondary ventilation; no moving parts to fail Adjustable inlet — fits all standard domestic basin and sink wastes 1¼" (32mm) multifit compression outlet — compatible with plastic, copper, and lead waste pipes Polypropylene construction — durable, corrosion-resistant, and chemical-resistant BS EN 274-1:2002 compliant — meets British and European performance standards Technical Specification Model AA10 Type Resealing bottle trap Water Seal 75mm Outlet Size 1¼" (32mm) Outlet Type Multifit compression Inlet Adjustable Material Polypropylene Pipe Compatibility Plastic, copper, lead Standard BS EN 274-1:2002 Weight 0.15kg Brand McAlpine You May Also Need Basin Wastes — Click-clack, pop-up, and slotted basin wastes Basins — Browse our full basin range All Wastes & Drainage — Bath wastes, shower wastes, and traps Frequently Asked Questions What is a resealing bottle trap? A resealing (or self-ventilating) trap is designed to prevent the water seal from being lost under syphonic conditions — where fast-flowing water in the waste pipe creates a vacuum that can suck the water out of a standard trap. The AA10 uses a hydraulic bypass mechanism to break the syphon and allow the trap to reseal automatically, without needing a separate anti-syphon valve or vent pipe. Do I need secondary ventilation with this trap? No — the self-ventilating design of the AA10 eliminates the need for secondary ventilation in most domestic installations. This makes it particularly useful in situations where running a vent pipe is impractical or impossible. Can I order if the item shows as out of stock? Yes — this product can be ordered even when showing as out of stock, and we'll fulfil your order as soon as stock is available. If you need a specific delivery timeframe, please contact us at customerservice@bubblegumbathrooms.co.uk before ordering.

Choose the F33R when the soil pipe entry point is significantly further from the WC pan than a standard connector can bridge, or where the routing requires a longer flexible run. At 850mm, it’s more than double the length of the F26R (410mm) and is the right choice for long-reach or heavily offset installations. 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 4″/110mm PVC-U and cast iron soil pipe — the standard soil pipe size used in UK domestic installations. Does the flexible body cause sediment build-up? No — independent testing confirms there is no sediment build-up in the flexible body of the F33R, ensuring clear flow performance over the long term. Can I order if the item shows as out of stock? Yes — we can order this product for you even if it shows as out of stock. Lead times may vary; please contact us at customerservice@bubblegumbathrooms.co.uk for availability.

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. Can I order if the item shows as out of stock? Yes — we can order this product for you even if it shows as out of stock. Lead times may vary; please contact us at customerservice@bubblegumbathrooms.co.uk for availability.

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).

Use a flexible connector when the WC pan spigot and soil pipe aren’t perfectly aligned — for example, where the pan is slightly offset, angled, or where a rigid connector can’t bridge the gap cleanly. The F26R’s 410mm flexible body gives you the movement needed to make a secure connection in these situations. What is the difference between the F26R and the F33R? The F33R is 850mm long — more than double the length of the F26R — making it suitable for installations where the soil pipe entry is much further from the pan. Choose the F26R for standard offset situations and the F33R where greater reach is needed. 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. Does the flexible body cause sediment build-up? No — independent testing confirms there is no sediment build-up in the flexible body of the F26R, ensuring clear flow performance over the long term. Can I order if the item shows as out of stock? Yes — we can order this product for you even if it shows as out of stock. Lead times may vary; please contact us at customerservice@bubblegumbathrooms.co.uk for availability.

A shallow seal trap retains a smaller water seal depth (19mm in this case) compared to a standard trap (75mm). It is used where there is limited space beneath the bath for a full-depth trap, such as with low-profile or freestanding baths with restricted underside clearance. Will this fit my bath waste? The Q10 uses a multifit compression outlet compatible with 32mm, 36mm, and 40mm waste pipes. It is designed to work with McAlpine bath wastes and most standard bath waste fittings. Check your existing waste outlet size before ordering. Is this suitable for acrylic baths? Yes — the Q10's seals are specifically designed to create a leak-free connection with fibreglass and acrylic bath surfaces, as well as steel baths. Can I order if the item shows as out of stock? Yes — most items can still be ordered when showing as out of stock. Lead times may vary.

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 ST90CPB-S-70 (this product) suits tray thickness 5–30mm and has a 1½″ solvent weld outlet. The ST90CB10-70 suits tray thickness 0–23mm and has a Multifit outlet compatible with plastic, copper, and lead pipe. Check your tray thickness and pipework type before ordering. What clearance does this trap require beneath the shower tray? The ST90CPB-S-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 ST90CPB-S-70 suits shower trays with a thickness of 5–30mm. If your tray is thinner (0–23mm), the ST90CB10-70 may be more appropriate — check the overlap range for your specific tray thickness. What type of outlet connection does this trap use? The outlet is 1½″ BSP 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. 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. If clearance is too restricted for this trap, the ST90CPB-S-53 offers a 25mm seal at just 53mm height. 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), 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.
