If you suspect that your pond has a leak, there’s no need to worry. Ponds can sometimes develop leaks, but the silver lining is that these issues are typically easy to fix. Most leaks occur in areas such as streams or waterfalls, making them relatively simple to identify. It's crucial to remember that on hot summer days, what appears to be a leak might be evaporation, a natural process that varies with the seasons and local climate, potentially leading to water loss of one to five inches per week. If you observe that your pond is losing more water than this normal evaporation rate, it’s time to investigate further.
Start by checking around the waterfall or stream for any damp soil or mulch, and if you find wet spots, dig around the rocks to see if water is escaping over the liner's edge. Raising the edges with soil, rocks, or gravel can effectively prevent water from flowing out. If no wet areas are found, turn off the water feature and monitor the water level; if it stabilizes, the leak is likely at or above that point. Additionally, water may be escaping along the pond's shoreline due to nearby plants or foot traffic, which can be remedied by reinforcing the edges.
If the water level drops to the skimmer opening, it may indicate a problem with the skimmer faceplate, often resolved by re-sealing it. However, if the water drains from your filter, the leak may be within the plumbing system.
Should the water level fall below the skimmer opening, the problem is probably in the pond liner itself. To identify a small tear or gouge, you may need to shift some rocks around. Once located, you can patch it similarly to how you would repair a bicycle tire.
Generally, pinpointing the source of a pond leak requires some investigative effort. With each drop in water level, you must decide whether to tackle the repair yourself or enlist a professional to restore your pond, allowing you to enjoy its beauty and the life it supports.
