Question:

Are submersible water pumps silent?

Hello,Thanks for looking into my question. I am a little confused on the definition of a submersible water pump. I am assuming that they are actually submerged but that sounds a bit unlikely in my mind. I suppose if it has a GFCI setup built in with everything sealed beyond the portion that pumps, it would work submerged without any risks involved.Are submersible water pumps meant to be fully submerged? I am mainly interested in this information because I am concerned about the amount of noise they make, being submerged seems likely that they would not be able to be heard. Thanks.

Answer:

they all make noise. my Ex had them all, arrrgh!
submersible pumps are absolutely able to be completely submerged. they come in may sizes based on outlet pipe size and horsepower ratings. they are also very quiet, usually about as loud as a fish tank air pump or so. you need to know distance from pump to end of outlet hose and rise(meaning how far uphill it will be pushing the water in order to size it properly. you will also need a waterproof spot to plug it in for outdoor applications.
This type of pump is designed to run under water and when submerged will make little noise.
Submersible water pumps are totally submersible. They are encased watertight. Mainly, since they are submerged inside a well away from the house, even if the made a little noise, you wouldn't hear it unless maybea bearing was bad, or the brushes were bad. When your pressure tank is filling, you can hear a little hum (IF you are at the scene of where the tank is. If you are talking about a sump pump that you use to pump standing water, say, out of your basement, since it is portable and awkward, there might be a racket when it is running. Papaw
