Three Guarantees Regulations for Mobile Toilets
The three guarantees regulations for mobile toilets mainly include legal basis, warranty period, warranty scope, three guarantees responsibilities, and warranty process, as detailed below:

I. Legal Basis
As a special facility, the warranty period for mobile toilets is governed by the 'Regulations on the Quality Management of Construction Projects'. This regulation provides a fundamental legal framework for ensuring the quality of mobile toilets during their construction, installation, and use, ensuring compliance with quality standards.
II. Warranty Period
- Regular Warranty Period: The warranty period for mobile toilets varies by manufacturer, typically ranging from 1 to 3 years. Products with simpler structures and stable quality may offer a 1-year warranty, while those with higher quality and more complex craftsmanship may have a warranty period of up to 3 years.
- Special Project Warranty Period: If the mobile toilet involves infrastructure projects (such as foundations and main structures), the warranty period is the reasonable service life specified in the design documents. For parts including roof waterproofing works and toilets with waterproofing requirements, the warranty period is 5 years; for electrical pipelines, water supply and drainage pipelines, and equipment installation, the warranty period is 2 years.
III. Warranty Scope
- Main Structure Issues: Structural problems such as cracking and deformation that occur during normal use are covered under the warranty.
- Internal Facility Damage: Damage to internal facilities such as toilets and washbasins due to quality issues is eligible for warranty claims.
- Exclusion Clauses: Damage caused by human actions (such as intentional damage or improper use) or natural disasters (such as earthquakes and floods) and other force majeure events are not covered under the warranty.
IV. Three Guarantees Responsibilities
- Construction Unit Obligations: In the event of quality issues during the warranty period, the construction unit is required to fulfill warranty obligations and bear赔偿责任 for any damages caused by quality issues.
- Responsibilities of Sellers, Repairers, and Manufacturers: According to the 'Product Quality Law of the People's Republic of China', the 'Consumer Rights and Interests Protection Law of the People's Republic of China', and relevant regulations, they are required to undertake responsibilities for repair, replacement, and return. For example, if the product has serious quality issues, users may request a return or replacement with a new product.
V. Warranty Process
Upon discovering an issue, users should promptly contact the manufacturer and provide information such as the product model, purchase date, and details of the fault. The manufacturer will arrange for a professional to assess the issue and confirm whether it falls within the warranty scope. If eligible, repairs or replacement of parts will be arranged as soon as possible to ensure the mobile toilet resumes normal use.
