Have you paid IQ tax on these hydropower projects?

Circuit part

The distribution box must be opened with leakage protection.

Many decoration companies use single switches to save money.

Reserve as many switch sockets as possible.

With the gradual rise of smart home appliances, there will be more and more electrical equipment at home in the future, and sockets should be arranged on every wall.

Strong current and weak current should be inserted into the tube separately, with an interval of at least 20 cm.

Where strong electricity and weak electricity intersect, weak electricity needs shielding, which many experts are too lazy to do.

Plan the lines and square numbers of strong electricity.

Reasonable arrangement of switch socket position

After the acceptance of the whole house, check the function and leakage of each socket.

Each loop of the distribution box should be marked for future maintenance.

Choose an open circuit to match the square number of the circuit, for example, a 4-square circuit with c25 or c32 open circuits.

Be sure to keep a copy of the hydropower construction drawing. You can take a photo on your mobile phone after the hydropower construction, and you need to check it when you punch holes in the wall or repair it in the future.

Waterway part

The main material of water pipes is PVC, which has been eliminated and is not allowed to be used as domestic water pipes. PVC pipes are generally used in sewers and threading pipes.

The water pipes of PPR are divided into hot and cold water pipes. The hot water pipe is thicker than the cold water pipe, and the heat and pressure resistance are better than the cold water pipe. Conditionally, it is suggested that the red line of PPR hot water pipe in the whole house be marked as hot water pipe.

When using the bridge elbow at the intersection of hot and cold water pipes, it must be installed on the cold water pipe with the convex part facing down.

Before hot-melt splicing, clean the hot-melt parts on both sides of the pipeline.

Following the principle of left heating and right cooling, installation errors often occur in hydropower construction.

There are fewer horizontal slots and more vertical slots in the wall.

The laying of hot water pipes follows the principle of shortest distance between heat sources. For example, if the water heater is installed in the bathroom, you can walk through the wall without walking around the kitchen.

After the waterway construction is completed, pressure test must be carried out, with the pressure of 6-8kpa and the test shall be no less than12h.

Water and electricity shall be constructed separately, with the circuit above and the waterway below, and the floor spacing shall not be less than 40cm. If there is an intersection, the waterway must be at the bottom.

Hot water pipes are recommended to be insulated.

When closing the house or before hydropower construction, check whether the water at the outlet under the whole house is unobstructed, and find the property in time if there is any blockage.

Where there is a floor drain, slope design and drainage test should be done to ensure that the floor drain does not accumulate water at the lowest point, which many masters can't do well.

The kitchen must be a floor drain, and many tragedies that flooded Jinshan started from the kitchen.

After the toilet drains, it needs protection. Many closed water tests have passed, but the house began to leak after several years of use, and the waterproof layer was often accidentally destroyed when backfilling.

Construction waste is not recommended for backfilling caissons in toilets, because the weight and density are different, which will easily lead to settlement and tearing of waterproof layer in the later stage.

It is recommended that all balconies keep the floor drain and power supply at the entrance of hot and cold water, which can be left unused and convenient when needed.

Deep-water floor drain must be made at the drainage position of washing machine, and shallow floor drain will occur when draining. This is experience and lesson, you will thank me.

If there is floor heating, the distribution manager should try to put it in the bathroom. The first bathroom is warm, and the second one will not flood the house if it leaks.
