I need some ideas on how to put a fountain pump on my simple birdbath? Do i need to drill a hole for the pump? Do i need a small or medium pump? Please Explain ,On ways to put this water pump on my birdbath feeder?
The best thing to do wold be to find a birdbath that already has the plumbing but barring that you could look for a battery or solar powered floating fountain pump.
This bb is fired ceramic so if you still want to drill, I imagine you'd have use a diamond bit on it. The recirculating pump could sit at the bottom of the stand but you'd need to gasket the hole(s) to prevent leaks. (You'd a supply line to the fountain and a return line back down to the pump). You'd also have to arrange for a power supply.
Another thing to keep in mind is that with a fountain, you can lose as much as 50% of your water to evaporation so you'd have to keep an eye on the water level.
