Takeaways

• 😀 Water connections should be made from the water tank through the bathroom and kitchen.
• 😀 Use 25mm solvent-welded pipes for connecting the washing machine and sink in the service area.
• 😀 Install an adapter with a faucet and a float valve to control water levels in the water tank.
• 😀 The water tank has an overflow pipe (ladrão) to prevent water overflow if the float valve fails.
• 😀 Adaptors with faucets are essential for connecting and distributing water inside the house.
• 😀 For the bathroom, use 25mm solvent-welded pipes, 90º elbows, and brass fittings for water distribution.
• 😀 If using an internal flush valve, connect it with 50mm pipes and distribute water from there.
• 😀 To prevent shower wire overheating or burning, use a ceramic connector.
• 😀 Sewage connections for sinks should use 40mm PVC pipes, and toilets should use 100mm PVC pipes.
• 😀 Install a siphon drain and a 50mm pipe connection for efficient drainage of the shower.
• 😀 Ensure proper ventilation by using 40mm PVC pipes for the vent column, extending 30cm above the roof.
• 😀 Install a grease trap (caixa de gordura) at the exit of the kitchen sink drainage system.

Q & A

What are the main steps involved in setting up the water supply system in the house?

The water supply setup involves connecting the pipes from the water tank to the bathroom and kitchen. You'll use solderable PVC tubes, a 90º solderable elbow, and brass fittings for the connections. The water tank needs an adapter with a valve and a float to control the water level.

How can you manage water level control in the water tank?

To manage the water level, install a float valve in the water tank. This valve will automatically control the water inflow and stop when the tank is full. Additionally, ensure the tank has an overflow system called 'ladrão' to handle any issues with the float valve.

What is the purpose of the overflow pipe ('ladrão') in the water tank?

The overflow pipe ('ladrão') is used to prevent water from overflowing the tank in case the float valve fails. It ensures that excess water is safely drained out of the tank.

What type of pipe is used for the water distribution in the house, and what is its size?

For water distribution, PVC pipes of 25mm diameter are used, along with various fittings such as solderable elbows and brass bushings for secure connections.

What is the role of the drainage system in the video, and how is it connected?

The drainage system is designed to manage wastewater from various parts of the house. It uses 40mm PVC pipes for the lavatory, 100mm pipes for the toilet, and 30mm pipes for the shower drain. All drainage lines connect to a main line leading outside the house, with an inspection box for cleaning and maintenance.

How can you prevent issues with the shower's electrical connection?

If the electrical connection for the shower is melting or producing a burnt smell, you should install a ceramic connector. This will solve the problem by ensuring a more reliable and heat-resistant connection.

What type of pipe is used for connecting the lavatory and the toilet?

The lavatory is connected using 40mm PVC pipes, while the toilet uses larger 100mm PVC pipes to handle the larger flow of waste.

What is the importance of installing a grease trap (caixa de gordura) in the kitchen plumbing system?

The grease trap (caixa de gordura) is installed to capture grease and fats from the kitchen sink before they enter the sewage system. This helps prevent blockages and ensures smoother wastewater flow.

What should be done if the system includes a flush valve (válvula de descarga)?

If the system includes a flush valve, you need to connect it with 50mm pipes and ensure proper distribution to the bathroom and toilet areas.

Why is it necessary to install a ventilation column in the sewage system, and how is it done?

A ventilation column is crucial for preventing pressure build-up in the sewage system, which could lead to blockages. It is installed using 40mm PVC pipes and should extend above the roof by at least 30cm to allow air flow and pressure regulation.
