My wife and I moved into a new house last year and it came with a very large overgrown fountain.
I was told the electrical for the pumps was not working, there were tons of bare spots where the rubber liner was showing, and very large boulders randomly placed on the hillside where i wanted to put my garden. I figured out the circuit breaker for the pump was weak and replaced it. Since then the pumps will run all weekend without fail. (4" 3/4hp electric pump) This spring I decided to clean up around the fountain, removing most of the overgrown plants and adding new ones from other places around the house where they were also overgrown. I moved the large rocks into place with my Jeep winch and a plastic shovel.
After that I dug out the bottom rock garden and filled in all the bare spots. 20 5 gallon buckets worth of rock, it was a long day lol. I used some paving stones to put a border around the sump where the pumps sit to help keep the rocks and debris out of the pump area
Once the hard work was done it was time to let the plants fill in and work on lighting. I started with standard side walk lights and then added solar spot lights to help add that little extra.
So far the fountain is filling nicely and I'm able to keep it clean with a weed whip and push mower.
