Existentialists often ask, "How deep is your well?" The question is meant to get the listener thinking about the depths of feelings he or she has in relation to others or an event. It helps you become introspective, even if for only a few minutes. However, in real life, this question is more frequently asked by well contractors, and rather than ponder the depths of your soul, the contractor really just wants to know how deep your water well is. This is important information because of its impact on deep well pumps, amongst the other following scientific reasons.
Water Pressure, Gravity and Depth
Deep well pumps are designed for, well, deep water. The water pressure in deep wells is such that these pumps need to not only withstand the pressure, but also be able to pump the water up out the wells against the force of gravity. The depth of your well dictates the size and PSI that a specific pump can manage, which is why the contractor needs to know an estimated depth.
If you have the current information on the depth of your well, provide the contractor with this information. It will help him/her determine which new pump to use, should you need a pump repair or replacement. It also helps him/her determine how deep to dig a new well.
Not surprisingly, the depth of a well can cause the weight of the pump system to feel heavier. It takes more strength or mechanical equipment to draw the pump up when the pump is already quite heavy, but then is submerged under fifty feet of water. It is akin to drawing up a deep sea diver in a very thick, very old diving suit. When the contractor knows both the depth of the well and the weight of the pump submerged, he or she can accurately calculate what it will take to draw that pump up out of the well.
Diving Versus Upward Winch Retrieval
Another aspect of deep well pumps and why the contractor needs to know its depth is the retrieval process for the existing pump. Is it safe enough for the contractor to dive down into the well to retrieve the submerged pump, or would it make better sense for an upward, mechanical retrieval?
If the latter has to be performed because the well depth is unknown or too risky, then a winch is connected to the cords and wiring that are connected to the well pump. The contractor flips a switch and the winch draws the entire pump up out the well. This is also a good solution if the pump is especially large or very heavy (as some of the much older models are).
