Many of the ponds we install include an auto-fill valve. This device keeps your water level consistent as ponds loose water due to splash and evaporation. We commonly install a simple water timer on the hose spigot, in order to feed the auto-fill every few days. Be warned! If you have one of these timers it is essential that you disconnect it during winter. Otherwise water will freeze, expand and break your nifty water timer. If you need any further help with your timer, try browsing the instruction manuals of some of the more popular models below.
