Your pond fountain sputtering mid-show slaps hard. When the fountain doesn’t work well, the spray turns weak, the pond looks tired, and every ripple falls out of place.
We’ve yanked leaves from intakes, swapped cracked O-rings, and nursed burnt cords back to life enough times to know the drill.
Therefore, we’ve put together this fountain repair guide to make sure your beautiful backyard show never stops. Before calling in for help fixing your fountain’s broken spray or lighting, read this guide. You might be able to fix the problem on your own!
Common Issues With a Pond Fountain and How to Repair Them
Small glitches pop up in every pond fountain. For example, a leaf may jam its screen, the cord might loosen, or a bubble could clog the volute and end the flow.
If any of these issues happen, you don’t need to call for help as you can troubleshoot them with some know-how of the fountain. Here’s a fountain repair handbook to make sure your pond never stops:
Spray Just a Trickle
If the fountain is giving off a thin spray line, it most likely means the pump or nozzle can’t breathe. You should pull the plug first and take out the pump while everything is still wet, so the dirt on it stays soft.
Then use a garden hose to spray the intake screen until you can clearly see through all the slits. Take off the nozzle, spray water through both ends, and tap it on a towel to knock out any sand stuck inside. Run your finger inside the nozzle to check; it shouldn’t be gritty.
And before you drop the pond pump back, snap on a mesh cover or slide it into a zip-up filter bag, as it helps pull in water from a bigger area and stops leaves from clogging the screen.
Lastly, place the pump flat on a brick, plug it in, and check if the fountain spray looks strong and even again. It helps to monitor the screens every week during fall and after big storms, so it doesn’t get clogged again.
The Pump Keeps Stopping
If your fountain keeps shutting off, it mostly means either the water level is too low or there’s a problem with the power cord. You should first check the water level; the pump should always be at least four inches underwater.
So if it’s too shallow, the pump can suck in air, which triggers its safety shut-off. At this point, you should refill the pond to the right level and clear out any floating leaves or debris while you’re at it.
But if the pump keeps shutting off even when there is enough water, unplug the fountain and check the entire power cord.
See if there are cuts, soft spots, or any cracks from sun damage. If the cord looks worn or if you're using an old extension cord, replace it with a heavy-duty outdoor one rated for more amps than your pump uses.
Lastly, press the reset button on the GFCI outlet (the one with the test/reset buttons), wrap any extra cord around a garden stake to keep it off the ground, then plug everything back in.
Fountain Pump Hums But Zero Water
If your pond fountain’s pump is humming but there’s no water spraying, it’s likely an airlock. You’ll have to reach into the water to get the pump handle and tilt the pump until the nozzle points straight up.
When you do this, bubbles will rise to the surface, which means the trapped air is escaping. Hold the nozzle in that position for ten seconds, then level the pump and place it flat on its pad. The water should start flowing right away.
If your fountain nozzle sits higher than the pond edge, you’ll have to prime it after each cleaning.
It basically means that you dunk the nozzle fully underwater and let it fill up before lifting it back into place, as air can sneak in when you move the pump or drop the water level.
Spray is Shooting Sideways
If your fountain spray is shooting off in random directions, its float is probably drifting (it is the platform that holds the fountain in place). You’ll have to pull the fountain in while it’s still running so you can see how it moves.
Check all the ropes holding it in place, as sometimes they stretch or the knots slip. Once it’s back at the center of the pond, tighten each rope and secure it to a brick or ground stake.
And always leave a little slack of about two fingers’ worth on each rope to help the float adjust naturally when the water level rises or falls by a few inches. If you get strong winds often, swap thin nylon ropes for stronger braided poly or stainless steel ones.
Nozzle Clogs with Green Slime
If algae builds up inside a fountain’s nozzle, it blocks water flow and weakens the spray. For this fountain repair hack, you’ll have to twist the nozzle off by hand and drop it into a cup of warm vinegar for 20 minutes as it breaks down the algae.
After soaking, scrub the inside and threads with a soft toothbrush, rinse well, and screw it back on.
You should remove floating leaves every couple of days to stop algae growth, so there’s less food for it to grow. You can also place water lettuce or lily pads around the base of the fountain since they provide shade that helps stop algae from forming.
Lights are Out or Look Dim
Underwater LED fountain lights can stop working if water leaks in through a damaged seal. You should turn off the power at the GFCI outlet and take the light out of the water to dry it off with a towel.
Then remove the cover, pour out any water inside, and let the parts sit in the sun for about an hour to dry.
Also, check the rubber O-ring (the round seal)—if it’s cracked or flattened, it won’t seal properly, so replace it with the same size and spread a little silicone grease on it before pressing it in place.

FAQs
What’s the easiest way to stop algae from taking over the spray head?
Clean the nozzle weekly and soak it in warm water to remove debris buildup, and scoop out the gunk from the pond water regularly. It’s also smart to use floating plants for shade and install a UV filter if algae keep coming back.
Can I keep the fountain running during winter without freezing the pump?
Yes, but only if you live in a mild climate. In freezing areas, you should take the pump out, dry it, and store it indoors. If you want to run it year-round, use a pond heater to keep water from freezing. Never let the pump run dry or get stuck in ice.
Will a strong fountain flow stress my koi or goldfish?
If the current is too strong or splashes into their swimming space, it can stress pond fish. That's why you should always aim the spray upward and away from fish zones. There should also be calm areas or rocks in the pond that fish can use for shelter.
