La Mesa Pond repair or fix my leak

Last week we had a call from a customer who has a pond in La mesa. the complaint was that the water keeps going down. Ok after a little discussion the customer agreed to turning off his water fall and watching the water level in the pond for a day or so.Well it didnt take more than two days for the pond water to stop going down.Now we had a good idea about where to look for a leak, The water level was an easy line around the pond to follow.After a little rock and boulder movement and a little time we found a hole in the liner.This pond had the typical EPDM rubber liner. The patch was a reltively simple fix . We then re-filled the pond ,while adding some De-chlorinator to treat the new water for the fish. The customer watched the level for the rest of the day and claimed it a fix. It doesnt always need to be a major thing , when your pond is losing water.
