Equipment for Plumbers

The wheel pipe cutter is suited to plastic and copper pipes and covers diameters from 3 to 35 mm, as stated in the title. The wheel makes a clean cut without swarf, which makes the later connection of fittings easier. For copper, the wheel should be turned gradually at each revolution, without overtightening, so as not to deform the pipe.

The pipe wrench is chosen according to the pipe diameter, in the case of the 1 to 3 inch models, and the jaw that adjusts its opening. Chrome-vanadium steel is forged to withstand the stresses of the work. To avoid damaging the pipe, rest the jaw on the part to be turned and hold the other end still with a second wrench.

The pressurisation kit with a diaphragm vessel absorbs pressure surges and reduces fluctuations in the water system. The electronic control panel manages the starting and stopping of the pump according to the pressure. The capacity of the vessel, such as the 8 litres stated in the title, should be chosen according to the pump and the flow rate required by the system.

The anti-backflow drain stopper is installed on the drain to stop water coming back and flooding the room, and is chosen between flexible and rigid versions according to the drain pipe. The sanitary fixture stopper for bidet, toilet and washbasin does the same job on sanitary appliances. Check the pipe diameter before buying, because the wrong model will not close properly.

The spiral auger is fed into the drain, rotating slowly, until it meets the blockage, which is then removed with small back-and-forth movements. Choose the diameter and length according to the drain, such as the 6 mm, 4.5 m auger with reel. Do not force it too hard, because you risk damaging the pipe, and always wear gloves.

The polyethylene sand trap separates sand from runoff water, while the grease trap holds back oils and fats from greywater, as indicated by the EN standards cited in the titles. Phytopurification (plant-based water treatment) with a horizontal-flow tray is a final treatment that uses plants and substrate. The choice and sizing should be agreed with a designer, taking account of local authorisations.

The float switch regulates the water level in the tank and starts or stops the pump according to its position. The audible and visual alarm device signals when the level becomes abnormal, so that action can be taken before flooding occurs. The single-phase inverter, for pumps up to 1.5 kW, controls the pump more precisely, but must be installed by qualified personnel.
