Hello everyone,
We are now looking to activate our (construction) water supply on the property.
For this, we want to use the existing (old) well. It was reportedly still in use "until recently." It consists of a pipe in the ground within a pit. There is a tap at the top. The pump and the connection (we thought simply a flexible hose) to the tap are missing.
The property is just under 1000m² (10,764 sq ft). The well will only be used for garden irrigation. The house water supply is connected to the municipal water system.
Which garden pump / well pump would you recommend? We are currently leaning toward the classic turquoise/light blue brand typically used for gardens. How should the pump be sized? Is it possible to leave the pump installed during the winter, or does it need to be removed because of frost?
Thank you very much for sharing your experience.
Best regards to all.

Gartenfreund22 Dec 2016 06:14The type of pump depends on the pipe used. If it is, for example, a 1 ¼ inch metal pipe, you will need a suction pump. If it is usually a plastic pipe with a diameter of 110mm (4.3 inches) or more, it is better to use a submersible well pump. Whether you need to fully or partially dismantle the system for winter depends on where the pump and the pipe are located. Since the pipe and the valve will definitely be exposed to frost at least partially, they must be drained.
You can easily determine the depth of the well and the water level yourself. You will need a string, a nut or another heavy object, something light such as a wine cork, and a folding ruler or something similar.
Tie the nut to the string and lower it into the pipe until it reaches the bottom, then you can measure how many meters (feet) deep the well is. Next, tie the cork to the string and do the same again; this will show you where the groundwater currently begins. The difference between the well depth and the water surface is the available water column.
Even if the water column is high, it does not necessarily mean you won’t have problems with water supply. It could be that your pump draws more water than can flow back in, or the water level is so low that a suction pump can no longer effectively lift water.

If you say so... Grundfos works for us. Then you have a well pump or deep well pump. These generally deliver lower flow rates but can handle higher pumping heights. The downside of a well pump is the cost. It is about ten times more expensive than a submersible pump.
For the construction phase, you could use a suction pump, provided the well depth is suitable and, as Gartenfreund mentioned, there is enough water constantly replenishing in the well. Or you could do it the right way from the start and get a well pump.

illusionslos13 Feb 2018 11:32Good day,
I’m bringing up this topic because we are currently focusing on well construction ourselves.
We want to purchase a deep well pump, but I’m a bit unsure about which pumps are commonly used.
The company Grundfos was recommended to us. I have looked at some of their pumps, but I would like to hear some user experiences.
Our well water is at a depth of 7 m (max. 10 m).
Which model would you recommend for this situation?

Gartenfreund13 Feb 2018 14:43First of all, hello and welcome to the forum.
I personally only know of one, and that is the one installed in the well about 40 years ago. According to the nameplate the well contractor attached here, it is also a Grundfos. To be precise, an SP4-13 with a maximum flow rate of 5 m³/h (132 gallons per hour) and 380 volts, which today would be 400 volts. It still runs perfectly.
Regarding the well itself, I would advise not to choose a pipe that is too small. You sometimes read that a pump only requires a pipe diameter of 110 mm (4.3 inches). However, I would prefer to have something with 150 or 200 mm (6 or 8 inches) installed. Also, it is better to drill 3 meters (10 feet) deeper rather than just barely reaching the water level.
For us, the water is found at about 7 meters (23 feet), but drilling was done down to 15 meters (49 feet). The pump is positioned (I am estimating here) at 13 meters (43 feet).
