Do you, by any chance, happen to live in a one-storey house but still experience drops in water pressure (i.e. your tap sometimes “fail” to give you adequate water)? If you answered “Yes” to this question, then, chances are, you might need a water pump in your house. Don’t have an idea which pumps to choose? Then read on to find out.
For starters, it depends on where you live. If, for example, you live in a city or a metropolitan area, chances are your tap water comes from underground water pipes laid out by the utility company several years ago, so the most likely reasons for the drop in water pressure are: 1) busted or corroded underground pipes, which means that they should be fixed first, making our discussion here moot; or 2) gradual decrease in pressure due to the numerous connections made to those government-owned underground pipes (i.e. the city’s water-consuming residents have “increased” in number). Whatever the case is, you can try using even just a one-line jet pump to try to artificially “increase” the water pressure in your tap and sort of “siphon” off as much water as you can, then consider installing a pressure tank to store the water and distribute it with the right amount of pressure around your houses’ kitchen sinks, lavatories, showers, etc. Of course, it would be advisable to involve professionals in doing all of these.
Now, if you are living in a rural area or outside the city limits, then perhaps your tap water comes from underground sources such as a well. First off, you should try to consult a water well specialist or geologist to find out if the decrease in your tap water’s pressure is attributable to the dwindling water supply in your water table (i.e. the reservoir of water lying underneath the grounds on top of, or near your house), or that your water table is just too deep, and the pressure has become inadequate. Most likely, the specialist will recommend that you use well water pumps.
Now there are many kinds of well pumps and you can go with several options here, depending on what the specialist says. For instance, if the water table is low-lying (i.e. less than 25 feet deep), he/she will probably recommend that you use single-drop jet pump systems. But if the water table is deep (i.e. greater than 25 feet), then a double-drop jet pump system or submersible (water) pumps, would probably be the way to go. Again, as in our foregoing discussion, you can pair this with a pressure tank to store the water and circulate it with the desired pressure around your house.
Bear in mind though that all we had done here is to just clue you in on what the experts might say in these situations, and the “final” recommendation will still come from them (or they might recommend something else entirely), so just trust the experts.
