The largest in the range of Hozelock Cascade fountain pumps, the 4000 is physically the same size as the 1500 model from the outside, but the motor contained inside is much more powerful.

You’ll receive your Cascade 4000 with 10 metres (33 feet) of electrical cable already installed, all you’ll need to do is wire it into your power source and it’s ready to go. The fountain attachments are easy to assemble within a couple of minutes and you’ll have a choice of three fountain heads with the option to run a waterfall.

Flow controllers on both the fountain and pipe outlet allow for customer flow rates so if you need more flow to your waterfall and less through the fountainhead this is easily achievable.

Great pump

The pump was delivered quickly and was the cheapest available online. It was installed easily and has cleared the pond in a matter of a few days....very impressive product.

Good product and excellent service

Very versatile product to run fountain or waterfall or combination of both. Easy to put together (several fountain style options) and install provided you have a mains supply near the pond. Service from Gardensite was first class from ordering through to delivery (after only a couple of days)

Works well

Bought a Cascade 4000 some 8-9 years back so when it died recently bough a new one. The design has not changed: it still has the annoying clip to close the two halves of the cage which occasionally comes apart when whacked by a hooligan Koi. This clip really should be sorted. Hence only 4 stars.

Phil Sanford Asked:

Will the Cascade 4000 pump water through a 15mm pipe up to height of one metre?

We Replied:

Dear Phil Thank you for your question. That should be fine, the standard size it will take is 25mm but you can put a reducer in place for a smaller pipe.

Gary Thomas Asked:

If I am only looking to have a waterfall feature without keeping fish, would I need a filter as well as the pump, or can I get away with only the pump?

We Replied:

Dear Gary Thank you for your question. We would recommend a filter with a UV lamp for any pond. Whether it has fish or not, there is always algae and debris that will get into the water and create an unpleasant appearance. if you call on 0121 355 7701 and let us know the measurements we can advise you on which filter would be required. Should you wish to contact us further or to place an order, please call us on 0121 355 7701. Thank you for using our online Q&A system. Kind regards Dan Everton
