Self-check of water and electricity systems: Prevention is better than cure
The water and electricity system is like the "heart" of the house. A senior master said: 90% of water and electricity accidents are worsened because small problems are not discovered in time in the early stage. It only takes 5 minutes per month to avoid maintenance costs worth tens of thousands of dollars.
1. Key points for self-inspection of water system
1. Water pressure test: preventing water pipe rupture
Normal household water pressure should be between 0.2-0.4MPa. If the water pressure exceeds 0.6MPa, it will accelerate the aging of water pipes and cause them to burst.
- Self-test method: Turn off all equipment and observe whether the water meter rotates slowly. If it continues to rotate, it means there is an invisible leak.
2. Check pipe joints and sewers
- Joint inspection: Check the kitchen and bathroom water pipe joints for water stains or mold.
- Drainage test: Pour a bucket of water into the floor drain and observe the drainage speed. If it is slow, it needs to be unclogged in time.
2. Key points of circuit system self-inspection
1. Inspection of distribution box: Preventing tripping and short circuits
The distribution box is the center of the home circuit. If a non-fuse switch trips frequently, it may be a sign of overload or short circuit.
- Self-inspection method: Check whether the terminals are loose and whether there are scorch marks. Make sure that the leakage circuit breaker test button (Test) can trip normally after being pressed.
2. Insulation check of socket and line
- Socket firmness: Check whether there is heat or peculiar smell. Bathroom sockets must be equipped with a splash-proof box.
- Ageing wiring: Check for cracks in exposed wires. The normal value of insulation resistance should be greater than 0.5MΩ.
Professional preventive maintenance recommendations
- Establish a utility file: Record the results of each inspection and maintenance records.
- Install smart monitoring: Use smart water sensors to monitor water leaks in real time.
- Regular professional inspection: For older houses, it is recommended to have a professional comprehensive physical examination every 3-5 years.

The latest standards for catching leaks and regulatory responsibilities in Shuangbei collective housing (2025-2026 practice)
According to Article 10 of the "Apartment Building Management Regulations" of the Ministry of the Interior and the trend of civil water leakage judgments in Shuangbei District Court in recent years, most water leakage disputes in old collective housing focus on the identification and definition of "exclusive parts" and "common parts". The roof platform and the public pipes are jointly owned by all separate owners, and the repair costs should be shared by public funds or all residents in proportion to their shares according to law; if the water supply and drainage pipes inside the floor slabs on the upper and lower floors are damaged, the pipes will be borne exclusively by the users or shared by the upper and lower floors.
At the engineering and technical level, modern professional leak detection has fully introduced non-destructive scientific testing, including "FLIR high-resolution infrared thermal imaging camera" (locating temperature difference leakage paths), "high frequency moisture meter" (measuring the moisture content of deep structures) and "pipeline air pressure and water pressure pressure test" (determining whether hot and cold water pipes are leaking). During construction, do not directly apply elastic cement or oil-based paint on the wet cement layer to seal it. Otherwise, the thermal expansion of internal water vapor will quickly cause the coating to blister and peel off, resulting in more serious powdery wall cancer. The standard construction method must first completely eliminate the water source, wait until the moisture content of the cement structure drops below 8%, and then apply the negative pressure resistant silicic acid permeability crystallized waterproof layer.
Recommendations on independent certificate storage and compensation process for water leakage repair
- Take photos and videos as evidence immediately: Use rulers to record the leakage range, frequency of water discharge, direction of water mark diffusion, and keep time stamps.
- Written notification and coordination survey: Officially notify the neighbors through the management committee or a certified letter, and agree on a professional third-party leak detection and appraisal unit recognized by both parties to conduct an on-site survey.
- The contract states the warranty terms: When signing the contract for the project, be sure to clearly specify the waterproofing warranty period (usually 1 year for partial repairs, and 2 to 5 years for the whole room or roof re-construction), and specify the water test acceptance criteria (such as a 48-hour water storage test in the bathroom shower area) to protect your own asset rights.
