How To Choose The Right Pond Hose And Clips For Your Setup

No matter if you're installing a pond filter, UV clarifier, or powering a waterfall, choosing the appropriate pond hose and clips is essential for success. The right hose for your setup provides strong water flow and prevents leaks, reducing energy waste and keeping your pond healthy.

In this guide, we will make choosing the right hose type and size simple, and explain how to avoid common mistakes, and which accessories will secure your setup.

Does pond hose matter?

Pond hose is more than just a connector, it's actually a key component of your pond pump and filtration system. Too narrow and it's prone to kinking, and can drastically reduce the water flow from your pump to your filter or feature, putting a strain on your pump. This can also be a cause of unhealthy and cloudy water.

Choosing the right pond hose

By far the most popular choice is flexible, ribbed pond hose, such as our Swell Anti Kink Pond Hose. Not only are hoses such as this durable, they're also UV resistant and weather proof, for year round use. These kink resistant, flexible hoses are discreet with a black finish that prevents algae growth inside the hose, perfect for connecting pumps to filters, waterfalls, or clarifier units.

Flexible hose tends to come in a range of internal diameters, typically from 12mm-50mm in size. It is recommended to use a hose as wide as possible, for a better flow. This is especially useful for higher capacity pumps.

Tip: Try adding an extra metre or two when measuring the length of hose, giving you enough slack for easy positioning and any future adjustments.

What size pond hose do I need?

It is essential to match the hose diameter to the pump flow rate to avoid frictional loss, which rapidly reduces the efficiency of your pump. Here is a general guide of flow rates vs hose diameter to help you get started:

Tip: Always use the widest hose that your pump's hose tail will support for minimal restriction and maximum flow.

Hose tail fittings

Stepped hose tails are the most common way pumps and filters are connected to hoses. These fittings are designed to be suitable for different sized hoses, and can even be trimmed to match your setup.

How to fit:

1. Slide the hose onto the stepped tail and mark the step that fits.
2. Remove the hose and saw off any smaller, unused steps.
3. Reattach the hose securely.

Removing smaller, unused steps is essential in keeping your pump performing well. For example, using a 50mm hose whilst leaving the 12mm step on the tail will restrict the flow to the narrow size.

What are hose clips for?

Hose (or Jubilee) clips are essential in creating a tight seal and preventing leaks. These accessories keep hose connections secure under the pressure of water.

What types of hose clips are available?

• Stainless steel: Both durable and corrosion resistant, perfect for most setups
• Plastic: Easy to install, but less secure for higher pressure systems
• Wire: Grips over the bumps of ribbed hose effectively

Ultimately, no matter which type you choose, you will need two clips, one for each connection. If you've decided to use a UV clarifier unit, you'll need 4, two before and two after the clarifier.

Tip: For extra security, use PTFE tape on the hose tails and threads, preventing leaks and improving the fit.

Hose connectors and fittings for custom setups

If you're looking at splitting the flow of water, for example between a filter and a waterfall, or wanting to restrict the flow to a gentle trickle, pond hose fittings are what you need.

Popular choices of fittings include:

• T-Pieces: Ideal for splitting pipe flows to multiple features
• Y-Connectors: Diverts water to multiple features easily
• Inline valves: Controls or limits the flow of water
• 90° elbows: Great for tight spaces or corners
• Replacement hose tails: Handy to keep spare in case of damage, or upgrades

When should I choose PVC or rigid pipes?

Clear PVC hose should be used with caution in ponds as it kinks easily, and allows internal algae growth. We would recommend only using this for indoor aquatics and features. Rigid pipes are best when used for large Koi ponds, as they provide a wider bore, and a cleaner, professional finish, especially when used alongside gravity-fed filtration systems.

Choosing the right hose and fittings is very important for the performance of your equipment and clarity of your pond. Whether you're setting up a brand new pond, or upgrading an existing one, it is best to remember to make sure your connections are wide, secure, and tailored to your pump's flow rate.
