Feed & EC
EC readings do not match
First compare the test methods, then compare the numbers. A supplier’s extraction result and drainage from a fertigated crop describe different samples.

Why does a cocopeat fertigation system need backflow protection?
Protect the source supply before adding fertiliser injection to an irrigation system.

Why the root zone matters
A coir crop may need regular feed, but concentrated solution must not return to the water source.
01 / OBSERVE
Three checks before you change anything
- Ask a qualified installer to specify protection appropriate to the source and local requirements.
- Check installation records, inspection dates and the designated testing procedure.
- Keep bypasses and connections documented when zones or injectors change.
02 / NARROW IT DOWN
What is the installation status?
Choose the closest observation for a suggested next check.
New injector planned
Include backflow protection in the design before commissioning.
Existing protection has no records
Arrange an inspection and establish a maintenance schedule.
Unexpected reverse flow suspected
Stop injection and have the system assessed before resuming.
03 / TAKE THE NEXT STEP
Leave with something useful
Retain the installer’s approved design and service record.
Keep in mind
A simple non-return valve is not automatically sufficient for every water connection.
