How to choose a bathroom radiator -5 options are required

The four common phenomena we often talk about are running, emitting, dripping, and leaking, which are common occurrences of hidden danger accidents. So it is important to choose manufacturers with warranty products here, and it is best to choose radiators produced by brand manufacturers! So here comes the issue of warranty and after-sales service. How to safeguard the rights and interests procedures is particularly important; Here, we need to have a product qualification certificate and an inspector's inspection certificate number
2. Must have a product warranty certificate (complete with manufacturer and insurance company information and official seal)
3. There should be a formal product sales contract (in addition to the store contract, there should also be a sales contract with the manufacturer. If it is in the mall, it is best to have a supervision contract in the mall. This ensures that there is no risk.)
4. There should be an installation contract for the product (if you need to install it together, but it is important to know that most radiator manufacturers are not responsible for the warranty of the installation part, and the installation is the responsibility of the direct installation and construction party.)
5. It is particularly important to have anti-counterfeiting labels and identification instructions (in order to ensure the authenticity of the purchased item and future warranty claims liability)
