What This Kit Replaces
Smart Garden has consolidated several older spare part numbers into the 1260028-G. If you previously bought any of the following, this is the updated replacement:
Old Pump Models
SP-160X3S — Cascade spare pump
SP-160XC3 — Twin panel spare pump
SP-160X03 — Pitcher & Tree Trunk pump
Old Panel & Pump Kits
2050PKS-G — Cascade spare kit
2130PKS — Various cascade kits
Why the Change?
Upgraded 1.8W glass panel (better output)
Accessories now included as standard
One universal kit instead of multiple variants
Same reliable pump design
Want Evening Running?
The 1260028-G is a direct-solar kit — your cascade runs only when the sun shines. If you'd like it to keep running into the evening, the SW1020D and SW1040D Solar Battery Hybrid Kits include an integrated battery that stores energy during the day. Check compatibility before ordering as hybrid kits fit a different range of features.

Swapping the panel and pump takes about 15 minutes. No tools needed — all connections are push-fit. The kit includes replacement tubing and fittings for the cascade connection.
Step 1: Remove the Old Panel and Pump
Disconnect the old solar panel cable from the pump
Lift the old pump out of the water feature reservoir
Remove the old solar panel from its ground spike or mounting position
If your old tubing is damaged or calcified, remove it too — the kit includes replacements
Step 2: Fit the New Pump
Place the new pump into the reservoir at the base of your cascade
Make sure the pump is fully submerged — it must be under water at all times
Connect the pump outlet to the cascade tubing (push-fit)
Route the pump cable up and out through the same channel the old cable used
Step 3: Connect the Cascade Tubing
If replacing the old tubing, fit the new tubing from the pump outlet up through the cascade tiers
Use the included fittings to secure the tubing at each tier
Make sure the tubing sits securely so water flows down each level without bypassing
If your existing tubing is in good condition, you can reuse it — just connect it to the new pump
Step 4: Connect the New Panel
Push the pump cable connector firmly into the panel socket — it's a push-fit connection
Insert the ground spike into soft ground in a sunny position
Angle the panel south-facing for maximum sun exposure
The 3-metre cable gives you flexibility to position the panel away from the feature
Step 5: Test
In direct sunlight, the pump should start within a few seconds
Check water flows evenly down each cascade tier
If the flow is uneven, adjust the tubing position at each tier
If nothing happens, check the cable is fully pushed in and the pump is submerged
Maintenance
Clean the solar panel monthly — dust and bird droppings reduce output
Rinse the pump filter screen every 2–4 weeks to prevent algae buildup
Top up the water level regularly — cascade features lose water to evaporation faster than pond fountains
In winter, bring the pump indoors to prevent frost damage
Check the tubing connections each spring before the season starts
This is a direct-solar cascade system — the 1.8W glass panel powers the pump directly from sunlight with no battery. Here's how each part works together to drive your cascade water feature.
1. Solar Energy Collection
The 1.8W glass solar panel absorbs sunlight and converts it into DC electrical power
The glass construction is more durable and efficient than plastic-covered panels — it handles UK weather year-round
At 1.8W it's a step up from the older 2050PKS-G panel, giving better output in lower light conditions
2. Direct Power to Pump
Power runs through a 3-metre cable from the panel directly to the submersible pump — no battery, no controller, no switches
The pump starts automatically when the panel generates enough voltage (around 4V) and stops when light drops below the threshold
The 3-metre cable lets you position the panel in full sun even if the water feature is partially shaded
3. Cascade Water Circulation
The submersible pump sits in the reservoir at the base of your cascade feature
It pushes water up through the internal tubing to the highest tier of the cascade
Water then flows down each tier by gravity, creating the cascade effect
Flow rate is up to 160 litres per hour in full sun — enough for a visible, steady cascade
4. What This Means in Practice
Your cascade runs during daylight hours in direct sunlight — typically mid-morning to late afternoon in UK summer
On overcast days, the cascade may trickle rather than flow strongly — this is normal for direct-solar systems
No running costs — the sun powers everything
No wiring, no mains connection, no electrician needed
If you want evening running, the SW1020D or SW1040D hybrid kits include a battery — but check compatibility as they fit a different range of features
