THE PRECAUTIONS OF EVA COIL HOSE

This article is combined from our AI friends and Jane, who works in Pingyang Bangdi Electronic Technology Co., Ltd with over 15-year experience of manufacturing expandable garden hoses in China.

Precautions 1: Surface

Before use, please check whether there are any crack, hole or crease on the surface of the hose, especially at the spring helix (which is prone to damage due to folding or squeezing).

And then, please also check whether the interface end (such as the connection head between the hose and the faucet/nozzle) is loose or deformed, which will cause leakage.

Tips: If you are using a newly purchased hose for the first time, it is suggested to conduct a water flow test for 1-2 minutes to observe whether there is any leakage at the joints or on the pipe walls. For example, with a 15m coil hose, it's crucial to ensure the connections are secure to avoid any issues during use.

Precautions 2: Water Pressure and Flow

Overpressure usage of water is strictly prohibited. It is necessary to confirm the maximum working pressure marked on the hose. Match it with a suitable water pump or faucet to avoid hose wall rupturing due to excessive pressure. Please open water with unscrewing slowly the valve to prevent hose fittings or spring structure from flash shock and leakage.

Precautions 3: Temperature Limitation

Clearly specify the applicable temperature range for the hose. Please do not transport hot water or use immediately after being exposed under low temperatures. This is to prevent the material from hardening, cracking, or softening and deforming.

When not use in winter, please must drain the water inside the hose, avoiding freeze. The water will expand to become ice, and then make the hose rupture.

When use in summer, please avoid prolonged exposure under sunlight, as high temperature can accelerate EVA aging (hardening, cracking). Moreover,  the temperature inside the hose is so high, generating steam pressure to lead to water leakage.

Precautions 4: Connection and Storage

Before connection, please make sure the seal ring is intact, which is tighten moderate force.Too loose may cause leakage, and too tight might damage the connector threads or the hose interface.

When store the hose, please do not bend or twist excessively. It should be coiled according to the natural arc of the spring, which can avoid the situations that the hose is unable to extend normally caused by deformation of the spring.

Precautions 5: Clean

Rinse the hose inside regularly with clean water to prevent the accumulation of silt and impurities, which can block the hose or wear the inner wall. If the hose is used for transporting medicinal solutions or fertilizers, it must be thoroughly cleaned after using, which can prevent chemical substances from corroding the material
