Q: What is the purpose of a flush valve in a drip irrigation system?
A: A flush valve removes sediment, sand, and debris from the sub-main or lateral lines in a drip system. This helps prevent emitter clogging and maintains consistent water flow.

Q: How does the flush valve operate?
A: The valve typically opens when the irrigation system is turned off, allowing trapped sediment to exit. Some models can also be opened manually during operation for forced flushing.

Q: Is the flush valve compatible with high-pressure pumps?
A: Yes, these flush valves are built to withstand operating pressures up to around 4 to 5 kg/cm² (~58–72 PSI), which is suitable for most agricultural pumps.

Q: Can I install the valve on a slope or uneven terrain?
A: Yes, but for best performance, it should be installed at the lowest point of the irrigation line to ensure complete drainage during flushing.

Q: Which flush valve size should I use?
A: Match the flush valve size to your pipeline diameter. For example, use a 50 mm flush valve with a 50 mm sub-main pipe.

Q: How often should I flush my irrigation system?
A: It depends on water quality, but flushing is generally recommended once every 1–2 weeks or as indicated by pressure drops or emitter clogging.

Q: Is installation complicated?
A: No, installation is straightforward. Each valve comes with threaded or socket ends for direct connection to PVC or HDPE pipes using standard adapters.

Q: Can these valves be reused across seasons?
A: Yes, they are made from UV-resistant and durable materials (PP/ABS and EPDM) for multi-season use with proper maintenance.
