AWS-24, Part by Part
48V packs · 24 watering heads · 30L tank · flow indicator with filter
An automatic watering system is not one product but eight, working together. Understanding which part does what is what separates a kit that runs for years from one that is blamed for a wet tray in its first month. Below is the AWS-24 as it actually arrives.
| Component | Its job in the system |
| Watering plug | Replaces the vent cap. Contains the float valve, the level lens and the water inlet. |
| Floater | Rises with the electrolyte; closes the valve at the correct level in that cell. |
| T-piece / L-piece | Joins heads into one run and turns the corner. Rotates, so the run follows the pack. |
| Flow indicator | Shows water moving, and stops when the last valve closes. Carries the filter. |
| Pipe 6mm / 8mm / 10mm | Watering line between heads; supply line from the tank. Two sizes, two duties. |
| End plug | Closes the run at both ends so the system is a sealed circuit, not an open pipe. |
| Couplings KV10 / KV6 | Connect the tank to the run; disconnect without tools, reconnect to the same seal. |
| Water tank | 30L for this kit, sized to a 24-cell string so one fill covers the pack. |
The Sequence, in Four Movements
1 · Water enters. Tank connected, flow through the supply line, into the indicator, then along the run and into each plug.
2 · Cells fill in parallel. Every head is fed from the same line, so no cell waits for the one before it. The flow is limited by the valve in each plug, not by the pipe.
3 · Valves close at level. As the electrolyte rises, the float closes its valve; pressure in the line is what finishes the job rather than a timer.
4 · Flow stops. When the last valve shuts, the indicator stops moving. Disconnect, and the pack is level. The lens on each head confirms it.
Why the Parts Matter More Than the Claim
Every failure mode in this product family traces back to one component. A blocked filter holds a valve open. A pipe under tension pulls a plug out of its seat. An end plug left off means the run never pressurises, so the far cells never fill. None of these are design faults; all of them are fitting faults, and all are avoidable.
A Note on Cell Count
The AWS-24 supplies twenty-four heads, which matches a 24-cell 48V pack. Some 48V batteries are built as 18-cell strings; where that is the case, the AWS-18 is the matching kit rather than a shortened AWS-24. Send the cell count from the battery label and the kit is supplied to it.
Maintenance That Fits in a Shift
Monthly: fill, connect, wait for the indicator to stop, disconnect. Quarterly: check the filter and the pipe ends. Annually: lift one head and confirm the float moves freely. Anything longer than that does not get done.
Choosing Pipe Size on Site
Two sizes exist because two duties exist. The smaller line feeds the heads and needs to be flexible enough to follow tight routing between cells; the larger line carries water from the tank and needs enough bore that the far end of the run still fills at a sensible rate. Using the small size for the supply is the mistake that makes a kit look slow rather than broken.
Where a pack is unusually long, the supply run is the part to check first: pressure drop along a long small-bore line is what leaves the last cells waiting.
A Short Fault-Finding Table
Indicator never stops. End plug missing, joint seeping, or a valve held open by grit in the filter.
Indicator never moves. Tank coupling not fully engaged, or the supply line kinked at a corner.
One cell stops early. Plug not seated, or that cell already at level — check the lens before assuming a fault.
Damp around one head. Plug not fully home; reseat it rather than tightening anything, since there is nothing to tighten.
