The area agreed and designated for the pond will normally be the least suitable for plants. This normally translates into a poor place for a pond to be sited. It will probably be in a dark and desolate corner where all the trees shed their leaves. Not the best scenario for a pond. One autumn will teach the fledgling pond keeper that this can make life very difficult. Removing a few wheel barrows full of leaves in spring is not the most fun of chores I can assure you.
The pond will be built over maybe a couple of weekends as the digging of the hole and getting that pond level are just not as easy as it looks in the guide. Once the liner has been set and you have finished the aesthetics with planting etc. water is added with great anticipation. As you switch on the pump and watch the water cascade down the waterfall, you feel a great sense of jubilation. At this time, many of you will notice the pond water dropping rapidly. As your heart sinks you realise there is a problem. Where is the leak?
It could be something as simple as a pipe not connected correctly, or worse, it could be under ground. Hours of investigation will show where the leak is and a patch fix is made using silicone or some other product. It will normally occur on the waterfall. It doesn't matter how careful you were, water will find its way through any small pin hole and the number of people who have a story to tell about their first waterfall is amazing. Let's assume that the leak is found and fixed in some way (otherwise this article could take longer than anticipated to read!).
