Frequently Asked Questions
How does an erosion feeder work?
Circulating water passes over solid tablets.
The tablets dissolve at a controlled rate.
A flow adjustment sets that rate.
No electricity is required.
It does not respond to demand.
Feed continues whether the pool is busy or empty.
When is a peristaltic pump the better choice?
Where dose must be precise or controlled.
It meters liquid chemical from a drum.
A flexible tube is squeezed to move it.
Output is repeatable and adjustable.
A controller can switch or modulate it.
Chemistry controllers normally drive one.
What is the routine maintenance item?
The peristaltic tube.
It is a wearing part by design.
Replacement runs on hours, not on failure.
A failed tube stops dosing silently.
Nothing alarms unless a controller notices.
Put tube changes on a schedule.
Can one feeder handle different chemicals?
No, and mixing them is dangerous.
Materials are rated for specific chemicals.
Acid and chlorine products must stay separate.
Shared equipment risks a violent reaction.
Storage must prevent leaks meeting.
Containment belongs in the specification.
Does a feeder need a flow interlock?
Every dosing device does.
Chemical entering static pipework concentrates.
It attacks fittings while sitting there.
It reaches the pool as a slug on restart.
The interlock should be hardwired.
Confirm it at commissioning.
