I was wondering if water pumps make any noise when they are submersed? Also, my pond is quite small and I don't want to scare my fish with a noisy pump. Thank you!
majority of the pond pumps you get to day are extreamly quiet and wont bother the fish or you at all
i've got efficiently used that pump for ten years, recirculating water interior a fountain. it quite is not submerged and is thoroughly silent as long as you do no longer permit debris accrue on the impeller section. I double filter out the water earlier it is going into the pump. that's wiped sparkling via unscrewing the bleed-valve on the top and letting the debris be cleared. you could take it aside there, too, yet take care re-assembling because of the fact the o-ring is comfortable.
It has been years since I had a pond. It was a freestanding pool with a fountain in it. I don't recall any noise from the submersible pump, only the sound of the splashing water. I doubt this type of pump has become noisier over the years. Below is a link to a site with many helpful articles about ponds, pumps, and systems.
