Old residential areas commonly suffer from low water pressure, aging circuits, and limited space, making it easy to encounter problems when installing smart toilets; Unable to start, frequent tripping, insufficient space; Waiting for difficulties.
1、 3 major challenges and solutions
Problem 1: Insufficient water pressure prevents the smart toilet from starting;
Reason: The water supply network in old residential areas is aging, and the water pressure on high-rise buildings is less than 0.1MPa (0.15MPa is required for smart toilets to start).
Solution: Install a silent booster pump (flow rate≥ 3m³); /h， Lift≥ 25 meters), installed between the angle valve and the smart toilet inlet, costs about 200-400 yuan.
Problem 2: Circuit aging, frequent tripping/leakage;
Reason: The sockets in old residential areas have no grounding wire and the wire diameter is too thin (1.5 square aluminum wire), which cannot carry the power of smart toilets (500-800W).
Solution: Pull a 2.5-square copper core wire separately, pair it with a 16A leakage protection circuit breaker, and choose an IPX4 waterproof socket. The cost is about 500-1000 yuan (including labor).
Problem 3: Limited space and restricted installation location;
Reason: The bathroom area in old residential areas is less than 3 square meters, and after the installation of smart toilets (70-80cm long), it is difficult to turn around.
Solution: Choose a wall mounted smart toilet (saving floor space, can be installed in the air) or a narrow body smart toilet (width≤ 40cm), suitable for small spaces.
2、 4-step renovation process (low-cost, high safety)
Evaluation status: Measure water pressure (using a pressure gauge), check the circuit (using a multimeter to measure voltage and ground resistance), and confirm whether it is necessary to install a booster pump or replace the circuit.
Choose compatible products: prioritize“ Low water pressure startup; “ Small size” “ Waterproof” The intelligent toilet avoids the cost of later renovation.
Professional construction: Hire certified electricians to install booster pumps and replace wiring, ensuring good grounding and no exposed wiring.
Safety inspection: After installation, test the water pressure, voltage, and grounding. Turn on the smart toilet with full function for 30 minutes and observe whether it trips or leaks.
3、 Additional suggestion: Simultaneously carry out aging friendly renovation
Many residents in old residential areas are elderly. It is recommended to install stainless steel handrails (with a load-bearing capacity of 150kg and a height of 70-80cm from the ground) and anti slip floor mats (R9 level anti slip) simultaneously to reduce the risk of falling while using the toilet.
