When to Replace Your Pump
Watch for these signs: the water flow has noticeably slowed, the pump is making a new noise it didn't make before, or the fountain keeps stopping and restarting on its own. Any one of these means the pump is on its way out. Don't wait until it stops completely — your cat's drinking habits will suffer in the meantime.

Don't Wait Until It Stops.
A slowing pump means slowing water. Slowing water means your cat drinks less. And less water means their kidneys are working harder every day. Replacing the pump early is a small cost for a big difference in your cat's long-term health.

A Worn Pump Is Silently Reducing Your Cat's Water Intake
Cats are wired to prefer moving water — the flow triggers their instinct to drink. When the pump weakens, the flow drops, and your cat's interest drops with it. Most owners don't notice until their cat has been underdrinking for weeks. The pump is the heart of the fountain. Keep it strong.
Common Questions
How do I know when my pump needs replacing?
How do I know when my pump needs replacing?
Three clear signs: the water flow has slowed noticeably, the pump is making a new noise (buzzing, rattling or grinding), or the fountain keeps stopping and restarting. Any of these means the pump is weakening. Don't wait until it stops completely — your cat's drinking will suffer in the meantime.
How long does installation take?
How long does installation take?
Under 2 minutes for most people. Remove the old pump, rinse the housing, drop in the new one, reconnect the tubing. No tools required. The pump is designed for easy owner replacement so you never need to send the fountain in for repairs.
Can I use a generic or off-brand pump?
Can I use a generic or off-brand pump?
Technically yes, but we strongly advise against it. Generic pumps are not calibrated for your fountain's flow rate or noise profile. Many customers who have tried off-brand pumps report louder operation, weaker flow, and failure within weeks. The genuine Nexafur pump is the only one we can guarantee will perform as your fountain was designed.
How long should a pump last?
How long should a pump last?
With regular cleaning, typically 12–18 months. The biggest factor is limescale buildup — cleaning the pump every 2–4 weeks alongside your filter change significantly extends its life. If your pump fails earlier than expected, contact us and we'll replace it under the 365-day guarantee.

What does the 365-day guarantee cover?
