The published company information does not define a standard number of hours or days for responding to a spray cleaner complaint. It does confirm that quality-related problems remain covered for three months after the sale, with products subject to full inspection. Customers who need an exact case schedule should email the technical service team with complete product and order information.
The available records separate the after-sales coverage period from the time required to answer an individual technical inquiry. Although Yiwu Zanchy confirms responsibility for quality problems for three months, it does not publish a fixed service-level target for replying to a complaint. The actual timeline may depend on the product involved, the operating environment, the information supplied, and whether additional testing is required.
For the listed sewer nozzles, the available configurations include one front nozzle with three rear nozzles or one front nozzle with six rear nozzles. The units use stainless steel construction and a rotating jet design. The stated minimum order quantity is 10 pieces, while the delivery period is 7–10 days. These specifications can help the support team determine whether a reported issue concerns configuration, materials, rotation, delivery, or cleaning performance.
Use-case information is also important. Sewer nozzles may be used for kitchen drainage lines, bathroom floor drains, and underground pipes. Other high-pressure cleaning accessories may be used for vehicle washing, courtyard floors, balcony stains, or dust removal from construction equipment. Describing the application, water pressure, equipment setup, and operating conditions gives technical staff a clearer basis for evaluating the complaint.
To help the technical team review a case efficiently, customers should include the product name or model, purchase or order details, quantity, date of receipt, intended cleaning task, and a precise description of the fault. Photos, videos, pressure readings, test results, and information about the connected equipment can also be useful. For a sewer nozzle complaint, specify the front and rear nozzle configuration and explain whether the rotating jet, spray pattern, or cleaning result differs from expectations.

Is there a standard response time for a spray cleaner complaint?
No fixed response period appears in the available company or product information. The documented commitment concerns quality support for three months after sale rather than a specific reply deadline.
What should I send with a technical complaint?
Provide the product model, order details, application, operating conditions, problem description, and supporting photos or test information. For sewer nozzles, include the nozzle configuration and details about spray rotation or cleaning performance.
Are the products inspected before shipment?
Yes. The available enterprise and product records identify full inspection as the stated quality-control method.
Does the published delivery time indicate the support response time?
No. The 7–10-day period applies to delivery for the listed sewer nozzles and should not be interpreted as a technical-support response commitment.
A specific technical-support turnaround for a spray cleaner complaint has not been published. Customers can rely on the stated three-month responsibility for quality problems and the company’s full-inspection process, but the timeline for an individual case must be confirmed directly. Send complete product, order, application, and fault information to receive a case-specific assessment. For technical assistance or detailed solutions, contact sales8@zanchy.com.
