McalpinePlumbing: Your essential buying guide
Start with the part that matches the fault, such as a valve for isolating water, a trap or waste-pipe for drainage, pipe clips for securing pipework, or a flush valve for a toilet cistern. Compare the fitting size, connection type, material and intended use to make sure it suits your existing plumbing.
Check what the valve needs to do. Ball valves are commonly used for shut-off control, check valves help prevent backflow, mixing valves blend hot and cold water, and flow control valves manage flow rate. Always compare pipe size, thread or compression fitting type, and pressure or temperature suitability.
Match the diameter, material and fitting style to your current pipework. For waste-pipes, traps and floor drains, consider the layout, required fall, access for cleaning and whether the fitting is designed for sinks, basins, showers or other waste outlets.
No. Room thermostats and underfloor heating thermostats usually control heating systems by room or zone, while radiator thermostats help regulate individual radiators. Compare compatibility with your heating set-up, control style and any accessories needed for fitting.
Water treatment and filters are worth comparing if you want to address taste, particles, scale or appliance protection, depending on the product type. Check what each filter is designed to treat, its connection requirements and replacement cartridge needs before choosing.

Plumbing jobs depend on accurate sizing and compatible fittings. This guide highlights the main product areas in DIY > Plumbing so you can compare suitable parts for repairs, upgrades and maintenance with more confidence.
For leak repairs and pipework changes, compare pipe parts, pipe clips and suitable valves first. These items need to match the pipe diameter, material and connection method already in place.
For drainage issues, look at waste-pipes, traps, floor drains and sink strainers. These parts are often chosen by outlet type, space under the fixture and ease of access for future cleaning.
Valves do different jobs, so choosing by function is important. A ball valve is typically selected for simple shut-off, a check valve for one-way flow, a drain valve for emptying part of a system, and a mixing valve for blending hot and cold supplies.
Before comparing options, note the pipe size, fitting style and whether the valve will be used with hot water, cold water, heating or another system. This helps avoid choosing a part that looks similar but is not suitable for the installation.
Heating control products can look similar but serve different purposes. Room thermostats control space temperature, radiator thermostats manage individual radiators, and underfloor heating thermostats are designed for floor heating zones.
When comparing heating controls, check compatibility with your system, the number of zones, the control type and whether any thermostat accessories are required for fitting or replacement.
If you are improving water flow or protecting fittings, compare aerators, flow restrictors, water pumps and water treatment options. Small changes at taps or appliances can require specific thread sizes, flow ratings or connection formats.
Water fault equipment can also be relevant where leak detection or water-related protection is part of the project. Compare the intended use and fitting requirements rather than choosing solely on appearance.
Waste and sewer components need to be chosen with layout, diameter and intended use in mind. Sewer pipes and related sewer products are different from indoor sink or basin waste fittings, so compare them within the correct part of the plumbing system.
For toilet repairs, flush valves should be matched to the cistern type and flush mechanism. For kitchen or bathroom sinks, strainers and traps should fit the outlet and available under-sink space.
