I wonder if anyone can help. We have lovely neighbours but they have recently put a second water feature in their garden. It is directly behind the fence where our seating area is. Unfortunately it is having a dire effect on our water bill due to frequent use of the loo due to the fairly loud trickling water! We have no intention of complaining about it and don't object to the sound but would like to do something to remedy the problem. We're not into water features really, but wonder if we got one where we could see as well as hear the trickling, it would have the required effect! Any ideas? Thanks for any help.
