Sewer Jet Cleaning Hose is widely used for sewage discharge at construction sites, municipal pipeline dredging and factory wastewater cleaning. Residual sewage, silt and grease tend to accumulate both inside and outside the hose after use. Storage methods directly determine the hose's working condition and service life. Standardized, all-round and refined storage management can effectively prevent the hose from aging, deforming, growing mold or sustaining physical damage. Daily storage must follow systematic maintenance principles.
First and foremost, proper selection of storage environment forms the core of maintenance for Sewer Jet Cleaning Hose. Always store the hose indoors in dry, ventilated and clean spaces; long-term outdoor storage is strictly prohibited. Ultraviolet rays in direct sunlight continuously erode the hose's outer material, hardening and embrittling the hose wall, causing discoloration and accelerating aging and cracking. Outdoor storage brings drastic day-night temperature swings and frequent dampness from rain and dew, leaving the hose persistently moist, which fosters mold growth and corrodes the outer cover. Meanwhile, the storage area should be kept far from high-temperature heat sources including boilers and space heaters. High temperatures soften the hose material, reducing elasticity and causing slack deformation. In subsequent operations, the hose is prone to bending collapse and poor rebound performance. In addition, the storage site must stay tidy, free of sharp gravel, metal edges, corrosive dust and liquid to prevent scratches and chemical erosion on the hose surface.
Second, pre-storage cleaning pretreatment eliminates most hose damage caused by leftover contaminants. After every operation, completely drain all residual sewage, sludge and debris trapped inside the hose, preventing these impurities from stagnating, fermenting and deteriorating within the sealed tube. Rinse the hose's outer wall with clean water to wipe away adhered grease, silt and mud. Air-dry the hose fully before coiling it for storage; never store the hose while damp. Long-term storage with residual water creates a sealed, humid internal cavity inside the coiled hose, breeding bacteria and mold. Persistent dampness also continuously softens the hose material, diminishing its abrasion resistance and anti-aging properties.
Finally, standardized coiling and routine maintenance details cannot be overlooked. Coil the hose naturally with a proper coil diameter and moderate tightness. Never force excessive bending or twisting, as permanent creases and wall collapse will form, irreparably damaging the hose's internal structure. Do not stack heavy equipment, pipes or construction materials on the stored hose. Prolonged heavy compression deforms the hose wall and creates uneven wall thickness, which easily leads to local bulging and cracking during later use. Take protective measures to isolate the hose from acid-base chemicals and industrial corrosive materials to avoid slow material erosion, and implement rodent and insect control to prevent gnawing damage. For Sewer Jet Cleaning Hose left unused for extended periods, unroll and air it out every one to two months before recoiling. This avoids fatigue damage to the hose material from long-term fixed bending and preserves the hose's excellent elasticity and working performance.
