Pond pump head height

Updated: 22 October 2026

Pond pump head height is why about 10,000 L/h on the box will not be the flow at the lip. You are planning a waterfall or a raised filter. That number is the easy end of the curve. At the printed maximum the flow is effectively none. The five amazon.co.uk listings saved on 19 October 2026 are on the [10,000 L/h pond pump comparison](/hub/garden-ponds/10000l-h-pond-pump). Products Compared did not run the pumps. If you buy through a link to amazon.co.uk, we may earn a commission at no extra cost to you.

Maximum flow and maximum head are opposite ends

That Pond Guy measures an open waterfall from the pond surface to the outlet. Maximum flow and maximum head are opposite ends of a curve. A pump sold at 10,000 L/h is near that flow only when it is pushing almost level. At the head on the box, delivery has fallen away. HOCANFLO states 11,000 L/h and 3.5 m. One review says 2.5 m of lift. An outlet near that maximum is not an 11,000 L/h waterfall. A stated 5.4 m or 5.5 m is the same kind of end point, not extra flow. Volume before height is the 10,000 L/h pond pump buying guide.

Measure from the water surface, then add pipe as an estimate

Start at the water surface, not at the pump on the bottom. Pipe, bends, a UV and ribbed hose add resistance the tape does not show. Pondone adds 10 cm of lift per 1 m of hose: 0.7 m of lift plus 5 m of hose totals 1.2 m in their example. Bradshaws Direct adds horizontal length divided by 10 to the vertical rise. Those are not one British rule, and they are not a measured loss on these five pumps. That Pond Guy’s case needs 6,000 L/h at the filter, plus 1 m of lift and 1 m they added for pipe, so 6,000 L/h at 2 m. The extra metre is their example. BARST states 19 mm, 23 mm and 35 mm tails. A tail size is not a percentage you subtract from 10,000.

What these five listings actually print

HOCANFLO: 11,000 L/h and 3.5 m. BARST: 10,000 L/h and 5.4 m. XOE-12000: 12,000 L/h and 5.5 m. None of those, and not the Varipump, prints a flow at 1 m or 2 m. Amazon’s table gives the Varipump 3.1 m. Evolution Aqua’s page says 5.5 m. Quote the source. The FM-10000 is the only saved mid-curve figure, and it is two statements. The bullet says 7,600 L/h at 2 m. A later view of the same page says 6,000 L/h at 2 m, and a description extract also shows 8,000 L/h at 1 m. The title says 5.3 m, the bullet 5.0 m, the specification 5 m. Do not average 7,600 and 6,000. One head and a plug is the best 10,000 L/h pond pump page.

A waterfall width is a different sum

Water Garden’s guide uses about 1,000 L/h per 10 cm of width for a trickle and about 2,000 L/h per 10 cm for a harder flow. A 30 cm trickle in that guide is 3,000 L/h, before head. All Pond Solutions uses 100 L/h per 10 cm of feature height. Height and width are not interchangeable, and the box figure was never the flow at the lip. Once you know the metres, the stop-points for fitting are on the how to install a pond pump page. Until a listing prints the flow at your head, you are guessing the middle of the curve.

Common questions

Is 10,000 L/h the flow I will get over a waterfall?
No. That figure is maximum flow at little or no head. At the maximum head on the box, expect effectively no flow. Four of these five listings do not print the litres left at 1 m or 2 m. Only the FM-10000 prints a flow at 2 m, and it prints two different ones. Buy for the point you measured, not the title.
Where do I measure head from?
From the water surface to the outlet, not from the pump on the bottom. That Pond Guy measures an open waterfall that way. Pipe and bends are then a shop allowance, not a loss measured on these pumps. Pondone, Bradshaws and That Pond Guy do not publish the same extra metres. Say which method you added.
How much extra head should I add for hose?
There is no single UK rule here. Pondone adds 10 cm per metre of hose. Bradshaws divides horizontal length by 10 and adds it to the vertical rise. That Pond Guy, in one example, adds 1 m for pipe and equipment on top of 1 m of lift. Label the allowance as that shop’s. Do not treat it as a measured loss on these five pumps.
The FM-10000 says 7,600 L/h and 6,000 L/h at 2 m. Which is the flow?
They are rival lines on the same ASIN. The saved bullet says 7,600 L/h at 2 m. A later view, and a description extract, says 6,000 L/h at 2 m, and that extract also says 8,000 L/h at 1 m. Do not average them. That Pond Guy’s separate 6,000 L/h example is not proof that 6,000 is the line to keep.
Why does the Varipump say 3.1 m on Amazon and 5.5 m on the manufacturer page?
Because those are two sources. The saved amazon table says 3.1 m. Evolution Aqua’s page says 5.5 m. This page does not collapse them, and it does not adopt a retailer’s 75 W figure. Both sources still state 10,000 L/h, which is the easy end of whichever head you quote.
