Pumps and Fountains for Container Water Features

Creating Moving Water in Small Spaces

Moving water plays a key role in many container features—often the reason for having a small feature: safe moving water on patio or garden.

All you need: suitable pump and basic understanding of flow rates and filtration. Pump-attached filters greatly enhance clarity; many pumps have built-in filters.

Almost all small features work with submersible pumps—wide range of shapes/sizes, sit underwater, recirculate as fountain/waterfall. Some need separate buried cable; many low-voltage pumps allow surface cable disguised by plants. Cable must be protected by plastic conduit where walked over. Low-voltage pumps suffice for most; only significant water movement needs more power. Power cable provision and concealment are the biggest challenges.

For straightforward fountains in sizeable uncluttered containers, solar-powered fountains work without electricity—small round unit with built-in pump and solar panel on water surface. Jet height varies with weather; warm sunny day yields 30-50 cm (12-20 in) jet.

Get flow rate right. Choose pump delivering slightly more than required—spare capacity allows fountain changes, reduces pump strain, extends life.

Volume needs for small features are modest; standard calculations may need scaling down. To assess pump capacity: pour water over cascade from hose at desired rate, collect for one minute, measure litres/quarts, multiply by 60 for hourly requirement. Potential fountain heights on pump packaging.

Fountain spray type depends on jet chosen—detachable, push/screw onto pump outlet. Many patterns; attachments for constantly changing sequences; sophisticated ones sync with lights and music.
