We require assistance with an existing fountain. We moved into the property during January 2020 and the fountain was very dirty, but filled with water. We emptied and cleaned it and filled it with water again. From there we noticed the fountain was starting to loose water drastically. The pump is working, but the fountain is definitely leaking / loosing water. We have filled it every month and then stopped at the beginning of winter as we assumed it needs to be waterproofed first. 2 of the 4 lion heads seems to be blocked. We therefore need assistance with a good cleaning and sealing / waterproofing and overall guidance on how to maintain the fountain. The idea is to add a few water lilies and maybe some gold fish in the end.
