Do you want to know which of the two possibilities between 1-1/4 and 2 well points are best?
We have taken the effort to present a thorough and informative guide so that you can determine which one would be best for you.
Understanding the term 1 1/4 vs 2 driven well point
A driven point well, also known as a sand point, is a tiny diameter well created by threaded couplings to join lengths of 1-1/4 or 2 diameter steel pipe.
A drive-point well screen is threaded to the end of the pipe string. The screen often has a drive-point or tip made of hardened steel at the bottom and is 2 to 3 feet long.
A sand point’s principal purpose is to keep sand out while allowing water to enter; it is made up of a steel thick wall pipe and a stainless steel screened well point, which is typically 1 1/4 or 2 inches in diameter and 36 inches long.
Function of the screen:
The screen’s function is to let groundwater enter the well while keeping out sand from the surrounding area. The pipe can then be used to pump water up to the surface. The well can be driven into the ground more readily because to the reinforced steel drive-point tip. The drive-point and pipe resemble a long spear.
Let’s start with the 1 1/4 vs 2 well point
- If the water table is less than 20 feet below the surface of the ground, 1-1/4 diameter well pipe can be used.
- If the water table is more than 20′ below the surface, a deep-well pump installation is required. For a jet and packer unit to be put in the well pipe itself, a two-inch diameter pipe is required. With the help of this assembly, water may be extracted from up to 100′ of depth.
This is due to the fact that different pumps and pumping equipment have varying capacities for extracting water from varied depths.
For these shallow water table depths, 1-1/4″ diameter well pipe is adequate. A shallow well pump can only draw water from a maximum depth of roughly 20′.
|1 1/4″||20 feet below the surface of the ground|
|2″||more than 20′ below the surface|
Deep into 1 1/4 vs 2 well point
1-1/4″ well point
With excellent water conditions, a 1-1/4″ well point guarantees 2 to 3 GPM per linear foot.
2″ well point
2″ well point is ideal for obtaining pure water at a higher flow rate. Additionally, it permits a flow of 3 gallons per minute through the screen and casing.
we believe that the 1-1/4″ is preferable for everyday use.
When to use 2 Diameter
A shallow-well pump can only lift water from a maximum depth of around 20 feet due to atmospheric pressure of roughly 14.7 pounds per square inch.
However, you must utilise drive pipe with a minimum diameter of at least 2 inches if you know the pumping water level will be deeper than about 20 feet.
This is required because the drive pipe needs to be big enough to fit a packer-jet assembly inside of it, which will allow the pump to draw water up from a deeper depth.
Expert Advice in using a well point that is 2 or 1-1/4 in size
For a reliable water supply line, most experts advise using a well point that is 2″ or 1-1/4″ in size. Additionally, both of them work well in various water depths to guarantee improved flow rates and facilitate water extraction without coming into contact with the sanitary or waste line.
Cost to Dig a Shallow Well 2 to 10 feet in diameter using 1-1/4″ pipe inside
Sand point wells use 1-1/4″ pipe inside the well casing and have a diameter of 2′ to 10′.
The two most important cost variables are the well’s diameter and the drilling depth to water and bedrock. While some shallow wells only go down to 25 feet to reach groundwater, the typical well is dug 100 to 300 feet deep. The volume of water flow is determined by the diameter of residential wells, which is frequently 4 or 6 inches.
Depending on how deep the water table is, digging a shallow well typically costs between $1,800 and $3,000, or $5 to $10 per cubic yard. The optimum locations for shallow wells are those without any rocks or bedrock, and they are typically 25 to 50 feet deep and 2 to 10 feet in diameter.
What is the cost per foot of Well Drilling and Digging?
The drilling process alone for a well costs $15 to $25 per foot. Irrigation wells cost $50 to $100 per foot, while geothermal wells cost $15 to $40 per foot to install a full well water system.
|Type||Avg Cost per foot|
|Digging A 3″- 4″ Well To 25′||$10-$25|
|4″ Residential Water Well||$25-$40|
|6″ Residential Water Well||$30-$65|
|8″ Residential Water Well||$60-$100|
|Irrigation or Agricultural Well||$50-$100|
Common questions and answers
Q: A sand point’s conventional well pipe size is 1 1/4 “and is effective at depths of 20 feet. If you go more deep, then 2” is a better choice?
A: Everything relies on how much water is present underground and how well the well was set up. No matter how big the pipe is, it won’t matter how much water there is if the well isn’t installed correctly.
If you’re pounding it down, 2″ pipe will produce significantly more water than 1.25″ pipe, but it’s much trickier to install. as well as a 2 “You can use a foot valve, though. With 1.25 “You must utilise a check valve on the surface and connect the suction line directly to the well point.
Q: When we should use a sand Point Well
A: A sand point well might not be the ideal option for your property if your soil is mostly clay or has numerous huge boulders. A sand point well, however, can be a decent alternative for you if you’re looking for a low-cost well installation option and your area’s water table is less than 30 feet below the surface.
Q: What is the price of drilling a 30-foot well pump?
A: Depending on the sort of pipe you use; it wouldn’t cost more than 10,000 to 20,000 dollars overall. The pricing would be reasonable if you planned to drill into the ground and use PVC casting pipes. Similar to this, it will cost more to dig a well pump 30 feet underground using steel casted pipe.
Q: What depth is ideal for a well point?
A: Extend to a minimum depth of 25 feet or a minimum depth of 10 feet below the static water level, whichever is greater. The minimum casing depth for privately drilled wells is the same as this.
Q: What exactly are 1 1/4 vs 2 well points?
A: A section of pipe known as a well point contains apertures wide enough to let water through but small enough to maintain the position of the water-bearing formation.
Q: What is a well point or driven point?
A: A well point (also known as a “driven point”) is a unique kind of well that is installed using a drive point and attached to the end of a small diameter pipe (often 1-1/4 to 2 inches) without an outer casing for protection.
By driving, pounding, or excavating down to the water table, well points are placed. These wells typically employ a suction pump to collect water and are built in shallow aquifers with sandy soils between 10 and 30 feet below the surface. Avoid using single pipe driven point wells under suction because they violate Appendix 5-B.
In 1 1/4 vs 2 well point we conclude this with following pints that:
For regular use, we think the 1-1/4″ is better, because 1-1/4″ well point ensures 2 to 3 GPM per linear foot in ideal water conditions
For receiving pure water at a higher flow rate, a 2 well point is optimal. Furthermore, it allows 3 gallons per minute to pass through the screen and casing.
For regular use, we think the 1-1/4″ is better.
Most experts recommend selecting a well point that is 2″ or 1-1/4″ in size for a dependable water supply line. Furthermore, they both function well in a range of water depths to provide increased flow rates and make it easier to remove water without coming into contact with the sanitary or waste line.
