McAlpine at APM: traps, WC connectors, waste fittings and gloves

Replacing a trap, matching a WC connector or picking up gloves for the next job? Use this guide to find the relevant McAlpine family at APM Plumbing & Electrical, then check the exact part before buying.

The directory covers our McAlpine catalogue references across plumbing fittings, accessories and gloves. Items without a current online buying page, and items needing availability or identification checks, are included as enquiries.

Need help matching a part?

Call 020 8702 8080 or 07737 263641. Send a safe photo and readable model code by WhatsApp to the shop or WhatsApp to our mobile, or email info@apmi.uk. Include the quantity and whether you need collection or delivery.

Gloves

McAlpine's range extends beyond plumbing fittings. We also carry black nitrile gloves in Medium and Large, with an X-Large enquiry reference below. Choose the correct size and the protection appropriate to the task. A glove photograph or the word “nitrile” does not establish suitability for a particular chemical, electrical work, heat or other hazard. Confirm the actual pack, label and relevant protection information before use.

Basin, sink and appliance traps

Start with the appliance and the existing waste arrangement. A bottle trap, tubular trap, appliance-inlet trap and straight-through trap are different choices. Match the inlet, outlet, available space, access for maintenance and any specified venting or resealing feature. A general Silentrap illustration does not mean that every trap includes an anti-syphon valve. Appliance hoses also need the correct receiving connection; a nozzle on a photograph is not a complete installation specification.

Bath and shower traps

A shower-tray opening, the outlet connection and the space below the tray are separate checks. Confirm the exact trap code and flange or finish, rather than choosing by a single nominal size. Bath traps and shower traps are not automatically interchangeable. Where an existing installation needs a replacement, send the old code and clear photographs taken without dismantling it.

Waste outlets and sink kits

Match the basin, sink or bath itself as well as the pipework. Overflow shape, slotted or unslotted outlet, flange, seal, basket, plug or clicker arrangement can change the part required. A sink kit may serve a particular number of bowls or appliance connections; check what is actually included in the supplied kit. Do not assume that a basket waste includes a trap, or that a trap includes the waste outlet.

Waste connectors, bends and adaptors

Identify both ends separately. A threaded coupling, a connection receiving pipe, a plain spigot and a solvent-weld socket do different jobs. McAlpine distinguishes Multifit and Universal connections, so the names should not be treated as interchangeable specifications. Match the exact model to the actual pipe material, outside diameter, thread and joint type with the installer. Flexible fittings also need their own model and permitted arrangement checked.

Overflow and condensate fittings

Overflow fittings, appliance waste connections and condensate accessories are not a general-purpose pressure-plumbing system. Check the service, both receiving connections, colour or finish where material identification matters, and the exact product code. A non-return valve, air-admittance valve and self-closing waste valve have different functions. Selection for a safety-discharge or condensate system needs the applicable manufacturer's instructions and a suitable system design.

WC connectors and accessories

Compare the pan outlet and the soil connection, then the actual angle, offset, available distance and any vent boss or extension needed. Similar white connectors can have different outlets. Rigid, flexible and MACFIT families should be selected by their exact code and actual installation requirements. A rodent barrier is a separately selected accessory, not an automatic feature of every connector. Have a competent installer confirm the arrangement.

Floor gullies

Choose a gully as part of the floor and drainage design. Confirm the exact model, floor finish, outlet, trap arrangement and access requirements. A tile-floor illustration does not prove suitability for a sheet floor, a particular waterproofing system or a given site. Ask us to check the actual product and documentation against the specified design.

What to send when you need a match

  • The model code on the existing part or packaging, if readable.
  • A clear, safe photograph of the whole item and its connections, without opening electrical equipment or dismantling a live system.
  • The fixture or appliance involved, the required quantity and any specified finish.
  • Measurements taken safely, including the available space and the actual pipe or receiving connection. Tell us how you measured them.
  • Whether you need collection or delivery, with the delivery postcode where relevant.

We can help identify catalogue options; the installer must confirm the final selection and installation requirements. Check exact pack contents, revision, connection limits and any required approvals against the actual item. Do not choose solely from a shared illustration, an approximate nominal size or a similar model name.

For practical collection or delivery information, see our contact page and delivery information. The applicable options depend on the item and destination.

Manufacturer references

Family and model names were checked against McAlpine’s current product catalogue, including its trap families, WC connectors and gloves. Where an exact reference remains unresolved, it is listed as an enquiry above. Range illustrations and general guidance are not evidence of the contents of a particular pack.
