i have a small area, about 5-10 feet deep at the most, maybe 15-20 feet wide (see pic attached-hopefully it uploaded).. i want to add a fountain that doesnt have a large spray.. only bubbles out of the water.. maybe 1-2 feet at the most.. i will be connecting it to power to run (not solar).. i would like something simple and cheap as to what i did in my other 2 larger ponds
bought a standard pvc cap, drilled holes in it, screwed on top, made a 4” pvc square float, put pump in an egg crate, secured egg crate to bottom of pvc float, and threw in water (top of pump is about 6-12 inches under water).. it sprays 10-15 feet in the air.. works perfect
my question is, since im not that familiar with pump hp pressures, which one of these pumps from home depot can I buy that is quality like the ones above, but only kinda bubbles out of water, or doesn’t shoot high in air
Here's my thoughts on it. Take it as it is given because I don't have any direct experience with any of those pumps.
If you have had good luck (reading that as reliability) with the pump from a year or so ago, I'd go with that pump. Instead of drilling a small hole in the PVC cap, I'd just try using a straight pipe with the pump mounted firmly on something under the water. I would start with the pipe above the surface of the water, and if it sprayed or bubbled up too far, I'd try one of two things:
Cut 1" off of the pipe, leaving the pump in the same position (i.e depth) in the pond. See how that works. Reduce the length of the pipe in 1/2" or 1" increments until you get the desired bubble or fountain effect, with the end of the pipe under the surface of the pond. If that doesn't work, on to step 2:
Transition the pipe from the pump to a larger diameter pipe, and go thru the same process as the first step. If that doesn't work, increase the diameter of the pipe and do it again.
The distance the water shoots up is a result of pressure and water velocity from the pump. Going to a larger pipe will reduce the water pressure at the exit, and also the velocity. Putting the end of the pipe under the water surface also reduces the water velocity.
