Best Gardena submersible pump

Updated: 22 October 2026

You want one pump for a water butt and a hose you still have to buy. Best is empty until that job is fixed. On that criterion, the best Gardena submersible pump in this amazon.co.uk set is the 4000/1, for hose pressure and a 4.7 from 66 reviews, not because it moves the most water. The full rows are on the [Gardena submersible pump comparison](/hub/garden-watering/gardena-submersible-pump). Peter F. read the listings captured on 21 October 2026 and the Gardena UK page.

Best for a water butt

The pick is the Gardena 4000/1, B0DMF7XPFW, at £79.99. Gardena UK lists 400 W, 4,000 litres per hour, 1.3 bar and 13 metres. The 20000 pumps are listed at 0.9 bar. For a hose, that gap is why the barrel pump wins. Screwfix shows the same £79.99. Skip it for grit, a 1 mm floor claim, or no outdoor socket. Those limits are on clear water or dirty water. No socket points at the 18 V tank pump.

What the reviews actually got

Reviewers describe a usable stream, closer to a kitchen tap than to a drainage pump. About 20 metres of hose was acceptable in one comment, and about 30 metres was weaker. The telescopic pipe is 615 to 815 mm, with a 210 mm extension sold separately. A 210 litre butt was within reach. A deeper tank was not. The hose is not in the box. Small sprinklers are on Gardena's usage line at 1.3 bar, not two roses on a long run. Sludge is on the Gardena water butt pump page.

When a drainage pump is the better buy

Muddy water is a different purchase. The dirty-water 20000 and the 2-in-1 pass 35 mm. The clear-water 20000 is the 1 mm residual claim. None of those mains listings has more than five reviews here. The FOTING 900 W, at £46.99, has 4.2 from 2,607 reviews, which is why it is the best-value drainage option, and only on that criterion. It is not a Gardena, and the plug shape is unstated. Clean rain and a hose still point to the 4000/1.

Price and stock

£79.99 is the stored amazon.co.uk price and the Screwfix shelf. One review mentions £64 on Prime Day, an anecdote, not a current offer. A snippet on 21 October 2026 said the listing was unavailable. If it is gone, Screwfix is the other public price at the same number, still without a hose. The cordless pump was £82.95 before a battery. The 20000 mains pumps were £50.99 to £59.99 for drainage.

Common questions

Which Gardena pump should I buy for a water butt?
The 4000/1, if you have a 230 V socket and the water is stored rain rather than grit. Gardena UK rates it at 1.3 bar and 13 metres, against 0.9 bar and 9 metres on the 20000 drainage pages. The amazon.co.uk line we stored is 4.7 from 66 reviews at £79.99. Buy a hose separately, and check whether a deep butt needs the 210 mm extension.
Is the highest litre rating the best pump?
No. The 20000 family is listed at 20,000 litres per hour and only 0.9 bar. The 4000/1 is listed at 4,000 litres per hour and 1.3 bar. For a hose from a butt, pressure is the criterion. The litre claim and the head claim are separate maxima, so the bigger number is not the stronger stream at the rose.
Is 4.7 from 66 enough when another pump has 2,607 reviews?
For a butt, yes, with the limit kept in view. Sixty-six reviews is a smaller sample than 2,607, and the larger sample belongs to the FOTING 900 W, which is a drainage pump at £46.99. That count supports a best-value note for drainage evidence. It does not make the FOTING the barrel pick, and the Gardena 20000 mains models, with three to five reviews, should not be crowned on stars.
Will it run a sprinkler like a mains tap?
Not like a kitchen tap on a long hose. Reviewers describe a usable stream at about 20 metres and a weaker one at about 30 metres. Gardena's own line for the 4000/1 includes small sprinklers at 1.3 bar. Two sprinklers, or a 30 metre reel, can drop that to a dribble. Test one rose on a shorter hose first.
What should I buy instead if the water is muddy?
Leave the 4000/1. Its fine filter is for rainwater, and Screwfix prints 2.5 mm in its own particle cell. Grit up to 35 mm is the dirty-water 20000 or the 2-in-1. If you want the large review sample, the FOTING 900 W at £46.99 is the drainage alternative, with an unstated plug and some early-failure reviews.
Is £79.99 the only UK price?
It is the price in our amazon.co.uk capture and on the Screwfix page. One reviewer paid £64 on Prime Day, which is a past anecdote. A snippet on 21 October 2026 said the amazon listing was unavailable. If that is still true, use another UK seller at a price you can see that day, and still budget for a hose.
What if that amazon listing is unavailable?
The stored facts do not vanish with the buy box. Gardena UK still publishes 1.3 bar, 13 metres and the telescopic range, and Screwfix still listed the pump at £79.99 without a hose. Check the live page before you order. Do not substitute a 20000 drainage pump just because it is in stock, unless your job has changed from a hose to emptying dirty water.
