Koi Pond Repair & Troubleshooting
When a pond loses water, a pump fails or the filtration stops keeping up, The Pond Pros find the cause and fix it. We handle pond leak repair, pond pump repair, pond filtration repair, pond liner repair and waterfall repair on koi ponds throughout the Inland Empire, San Gabriel Valley, Orange County and Los Angeles — including La Verne, Claremont, Upland, Ontario, Glendora, Jurupa Valley, Riverside, Colton, Fontana and Chino. No problem is too big for us to solve.

What we repair
Pond leak repair
We find where the water is going — liner punctures, settled rock at the waterfall, plumbing joints, skimmer seams — and fix the leak instead of guessing.
Pond pump repair and replacement
Pumps that hum but don't move water, trip the breaker, or have simply worn out. We service what can be saved and size the right replacement when it can't.
Pond filtration repair
Cracked filter housings, failed UV lamps, clogged or undersized biological filters and bad plumbing that starves the filter of flow.
Pond liner repair
Shredded, punctured or sun-damaged liners, patched or replaced, with the rockwork reset on top.
Waterfall repair
Streams that lose water behind the rock, spillways that have shifted, and waterfalls that have gone quiet because the plumbing or pump can't keep up.
Plumbing and circulation fixes
Leaking fittings, broken check valves, auto-fill valves stuck open, and dead spots where the water never moves.
Signs your pond needs repair
- The water level drops faster than evaporation can explain, or the auto-fill is running constantly.
- The ground is wet or soft next to the pond or along the stream.
- The pump is running but the waterfall has slowed to a trickle, or it keeps tripping the breaker.
- The water stays cloudy no matter how often you clean the filter.
- Your koi are stressed, gasping at the surface, or you're losing fish.

HOW IT WORKS
What happens when you call
Call 840-205-9394
Tell us what you're seeing. If you're losing water fast or the pump is dead, say so and we'll move quickly.
We find the cause
Dennis assesses the pond, the plumbing and the equipment and tells you exactly what's wrong and what it will take to fix.
We fix it, or tell you when a remodel is the better deal
Most problems are a repair. When a pond has been patched too many times, we'll show you what a remodel would cost instead of selling you another patch.
