What’s the difference between the first fix and the second fix plumbing?

In essence, the first fix involves laying the groundwork for your system, focusing on installing pipes and essential fixtures before surfaces like walls and floors are finished.

In the first fix, we will fit the underground pipe work, waste pipe for the bathroom (and shower valves) and the kitchen. Then this is followed by installing the hot and cold water pipework for the kitchen and bathrooms, then the central heating flow and return for the radiators.

We will also fit the pipes for the boiler or hot water cylinder. 

The second fix, on the other hand, occurs after these surfaces’ internal walls and floor are complete and entails fitting the visible components such as taps, showers, and sinks.

In the second fix, we will install the boiler, hot water cylinder, toilet, sink, tap, and showers.

What are the stages?

Planning the pipework: at the heart of any successful project lies meticulous planning. We carefully strategize the layout of pipework, ensuring optimal functionality and efficiency. Factors such as water pressure, flow rates waste pipe used, and building regulations are taken into account to create a comprehensive plan that will guide all the work to follow.

For bigger projects, we also need to design the system with a heating system designer engineer.

Boilers and flues first fix

Central heating systems are a vital aspect of many home setups. MML plumbers install boilers and flues, positioning them strategically to keep hot water and provide efficient heating throughout the property. Attention to detail is paramount to guarantee safe and effective operation, especially when connecting the boiler to the house or existing system or installing a new one in a new build.

Wastewater installation

Effective bathroom wastewater management is essential for maintaining hygiene and sanitation standards. This stage involves installing drainage pipes and drainage systems to safely and efficiently remove wastewater from sinks, showers, toilets, and other bathroom fixtures. MML plumbers ensure that the waste pipes are properly connected and positioned to prevent backflow and facilitate easy access for maintenance and testing.

Installing Drainage Systems Along with the Water Supply Pipes

In addition to wastewater ground drainage systems, it includes the installation of water supply pipes. These pipes deliver clean, potable water to various fixtures throughout the property, such as taps and appliances. We use materials like push-fit pipes or solvent weld joints to ensure secure connections and prevent leaks. Attention to detail at this stage helps prevent issues such as leaks and pressure fluctuations, and all the work is done by building regulations.

Installing Heating Systems

In colder climates, heating systems play a vital role in maintaining comfort and warmth within a property. In this stage, we include the fitting of space heating systems, such as radiators or underfloor heating. Our heating engineer carefully fits pipes and connects radiators to the central heating system, ensuring proper insulation and preventing heat loss. For radiators and underfloor heating, they lay down the pipework or heating mats and connect them to the boiler or heat source on the second fix.

First-fix electrics

In addition to plumbing work, the first fix often involves coordinating with electricians to install electrical fixtures, appliances and wiring. MML PLumbings ensures that any pipework or fixtures do not interfere with the electrical installation and vice versa. This may include installing conduits for electrical wiring, fitting face plates for the light fixtures, switches and sockets, and positioning light fittings and fixtures.

Tightness Test

Once all the first-fix plumbing work is complete, plumbers conduct thorough testing to ensure that everything is functioning as it should. This may include pressure testing the pipework, checking for leaks in waste pipes, and verifying the proper operation of heating systems and appliances. Any issues are addressed immediately before proceeding to the second fix plumbing stage.
