I have lived in my house for a year. It is the developer's responsibility that the ground heat pipe leaks this year. I can ask.

According to Article 40 of the Regulations on Quality Management of Construction Projects, the minimum warranty period of construction projects is:

(a) the reasonable service life of the building foundation engineering, foundation engineering and main structure engineering specified in the design documents;

(2) 5 years for roofing waterproof works, toilets, rooms and external walls with waterproof and anti-leakage requirements;

(3) The heating and cooling system consists of two heating periods and cooling periods;

(four) electrical pipelines, water supply and drainage pipelines, equipment installation and decoration works, for 2 years.

Hurry up and find the developer. After the second heating period, there will be no warranty.
