Push Fit
Push-fit waste fittings for compatible plumbing layouts
Choose FloPlast push-fit waste fittings for the connections, direction changes and supports specified for your waste pipework. JJ Building Materials' Push Fit collection brings together couplings, bends, tees, reducers, socket plugs, pipe clips and tank connectors in a range of sizes and colours. These are waste-system components, distinct from push-fit fittings for pressurised hot and cold water supplies. Start with the intended system and layout, then select the exact fitting and variant required.
Whether you are replacing a damaged component, adapting a basin installation or planning new pipework behind a cabinet, accurate identification makes the order easier. Record the pipe system, nominal size, fitting shape and connection arrangement. Check the current product-page options before purchasing, and use the manufacturer's instructions and your installer's specification for assembly and system design. A familiar colour or a similar-looking socket is not enough to establish that a part is the correct match.
Identify the system before selecting the size
FloPlast's push-fit waste range uses polypropylene components with ring-seal connections. It is designed around compatible waste pipework and does not require solvent welding. Keep that identity clear when comparing products: push-fit and solvent-weld waste components should not be treated as automatically interchangeable simply because they share a nominal size. If an existing installation is uncertain, photograph markings and connections and obtain identification advice before ordering replacement parts.
The range includes nominal 32mm, 40mm and 50mm options across many products, but not every component has every size available in this collection. A nominal size also does not tell you the complete physical geometry of a fitting. For tight spaces, confirm the relevant dimensions and connection positions. This helps avoid ordering a technically compatible part that cannot reproduce the required arrangement within the cabinet, behind a fixture or beside an existing pipe route.
Couplings and reducers for defined connections
The FloPlast push-fit waste coupling joins compatible sections within the specified system. Include the coupling's position on the layout, particularly in repair work where access or movement may be limited. Do not treat it as a universal adapter for unidentified pipework. Where old and new materials meet, the transition should be assessed separately so the selected connection matches the actual components and the manufacturer's requirements.
For an appropriate size transition, browse the FloPlast push-fit waste reducer. Current variants include 40x32mm, 50x32mm and 50x40mm combinations. Record both numbers on the buying list and confirm the required colour. A reducer changes between specified sizes; it does not automatically solve a compatibility issue between different systems. Its use should follow the planned drainage arrangement rather than being introduced simply because a different pipe size happens to be available.
Bends for changes in direction
Compare the FloPlast 90 degree waste knuckle, 92.5 degree waste bend, 135 degree obtuse bend and 90 degree conversion bend against the route your installer has planned. Keep the full product description on the order. Similar angles can conceal differences in shape or connection arrangement, and the word conversion should not be read as a universal claim that a fitting joins every waste-pipe material or system.
FloPlast also describes the obtuse bend as 135° (45°), using two angle conventions for the same shape. Check the exact product identity when a contractor's shorthand differs from the catalogue wording. For a confined installation, sketch the route in plan and side views and note available depth. The shape of the fitting, adjoining pipe lengths and nearby furniture all affect whether the proposed arrangement can be assembled and maintained conveniently.
Tees, socket plugs and tank connectors
A FloPlast push-fit waste tee creates a branch within an appropriate layout. Its position and size should be part of the system plan, especially where several fixtures connect to the route. Explain which fixture each branch serves and confirm the arrangement with the installer. A tee should not be added simply because it offers a convenient-looking connection without considering the rest of the drainage system and the space around it.
The FloPlast push-fit waste socket plug closes a compatible socket where that is specified. Keep the purpose of any closed branch clear in the job record. For suitable tank applications, the FloPlast push-fit waste tank connector provides another distinct component choice. Do not confuse a tank connector with a basin waste or assume that similar appearance makes it appropriate for every fixture opening. Select the connection intended for the particular application.
Pipe clips and practical support planning
Floplast push-fit waste pipe clips belong on the materials list alongside the connection fittings. Their size should match the specified pipe, and the quantity should follow the support arrangement established by the installer using current manufacturer guidance. Supports have a different role from sealed joints. Counting bends and couplings alone will not tell you how many clips are required or where they should be placed.
Confirm the surfaces the supports will fix to and any suitable fixings needed separately. Consider drawers, shelves and removable access panels before the route is finalised. Pipework should not depend on stored items or furniture edges to hold it in place. A practical layout allows the intended support and movement requirements to be met while keeping the necessary components reachable for future inspection and servicing.
Choose from the current size and colour options
White, black and grey variants appear across much of the 32mm and 40mm range, while the listed 50mm options are grey. Check each product individually. The current 92.5 degree bend and conversion bend pages show 32mm and 40mm choices. The tank connector has white and black 32mm options, with white, black and grey listed for 40mm. Do not assume a size or finish from the manufacturer's wider catalogue is currently selectable on every store listing.
Choose compatibility and function before appearance. If a preferred colour is not available, discuss an acceptable finish without casually changing the required size or fitting type. When placing an order for someone else, include the selected variant and product link with the quantity. A photograph may represent several options, so the basket description is an important final check that the intended size and colour have actually been selected.
Five guides to help plan your order
Our buying guides cover system identification, bend selection, surveys around fixtures, component quantities and maintenance access. Use them to organise a clear enquiry and prepare a reviewed shopping list. They focus on practical buying decisions and the current catalogue, while installation details and drainage design remain governed by the appropriate product instructions and the requirements of the particular project.

Measure, count and inspect before installation
For a replacement fixture, record the new outlet position and the usable space around it. Include the final cabinet layout, not just the empty opening before shelves and drawers are fitted. Photograph the existing route and any readable markings. Ask the plumber which components can remain and which need changing. A similar-looking basin or cabinet can still alter the plumbing space enough to require a different arrangement beneath it.
Count components from the agreed layout, with separate lines for shapes, sizes, colours and planned spares. Include supports and any closures or transitions. Check the delivery against that list before work begins, retaining labels where identification may be needed. Before pipework is concealed, agree the appropriate checks with the installer and keep photographs of the completed route. Those records can make later maintenance or refurbishment enquiries much more straightforward.
Push-fit waste fittings FAQs
Is this collection suitable for water-supply plumbing?
The products described here are push-fit waste fittings and accessories. They should not be selected for pressurised hot or cold water supply simply because the jointing term sounds familiar. Identify the intended service and use the system specified for it, keeping waste and supply-side components clearly separated on the order.
Can I connect any pipe with the same nominal size?
Do not assume compatibility from the nominal number alone. Confirm the material, system and required connection. Existing installations may contain alterations or different products. Where identification is unclear, provide photographs, markings and measurements to the supplier or installer before choosing a replacement or attempting a trial connection.
What is the difference between a coupling and a reducer?
A coupling joins compatible sections within the specified arrangement, while a reducer provides a defined transition between sizes. Record both sizes for a reducer. Neither description automatically establishes compatibility with another waste system, so any material transition should be assessed and specified separately rather than improvised from a similar-looking part.
Why do some bends have two angle descriptions?
The manufacturer may describe the included angle and the change in direction together, such as 135° (45°) for an obtuse bend. Match the exact product, shape and selected size. If a materials list uses shorthand, confirm the intended catalogue item before ordering instead of treating the two numbers as unrelated fittings.
Do I need to order clips separately?
Include the specified clips and suitable fixings in the installation plan unless a product explicitly states they are supplied. Their quantities should follow the support arrangement for the pipework. A complete set of connection fittings does not by itself provide the supports needed to keep the finished route correctly positioned.
What should I check before buying replacement fittings?
Confirm the system, size, shape, connection geometry, colour and quantity. Include available space and access where the fitting sits inside furniture or boxing. If the fixture or route is changing, ask for a reviewed layout rather than assuming the old arrangement remains suitable. An accurate brief helps make the purchase dependable.
