One of the last things to build and test with all the water stuff, was rain. So I added a small installation with sprinklers that get fed directly from the tap water.
Rain Down On Me
The rain installation is controlled electronically (duh!). On the WaterWorks under the paludarium, I have one electromagnetic valve that can be opened to feed the rain installation:
The valve on the right has now been connected as well with a thin black tube. This tube is fed upwards, and enters the paludarium through a cut off edge in the rear glass panel. Once inside, it is split into two:
The splitter shown in more detail:
The two tubes run from right to left. The one in the rear carries four sprinklers that almost mist the water. They are the primary sources for rainfall onto the plants that will grow on the background. The second tube runs across the front. For now it only has two spinklers, that shoot out a wall of water under a 90 degree angle, so they shoot water to the other side of the paludarium all the way through to the back, without shooting outside (hopefully 😉 ):
Fully powered by water pressure from the tap, there is only a click to activate the magnetic valve. Then there is just the sound of spraying… No more noisy pumps to build water pressure. That is the upside. The downside is that I now pump tap water directly into the paludarium. Maybe I’ll add a container sometime that will allow the tap water to reach room temperature before it is sprayed inside. I’ll have to see how much the rain influences the air temperature when it rains down, and decide from there whether I need to add some stuff or not.
