Water and electricity renovation is generally a comprehensive renovation based on the advice of the water and electricity master and the personal preferences of the owner, including water and electricity renovation and circuit renovation. The first step of water renovation is to replace the indoor water pipes with better ones you buy. According to the master's advice and personal preferences, set up the various water outlets in the kitchen, bathroom and balcony, including the location of the vegetable sink, the location of the small kitchen treasure, the location of the bathroom sink, the location of the water heater, the shower, the location of the balcony laundry pool, etc., and how the hot water should go, such as guiding the hot water from the electric water heater in the bathroom to the kitchen, etc., so it is necessary to determine the location of each water outlet. Then see how the water pipes should go, whether they should go against the wall or in the middle, etc.
