In addition to the exact choice of equipment for supplying water to the house from the well, it must be properly installed. These two conditions will ensure the best and long-term operation of the entire water supply system. Considering that pump models are also surface, the installation method is somewhat different. This is worth talking about in detail.
Submersible and surface pumps (stations) - features
Depending on the ultimate goal - to provide water for a summer cottage or a residential building with year-round living - equipment is chosen. For submersible and surface pumps, the distinctive characteristics are not only in location.
For example:
- Pumping stations (surface units) have a limited lifting depth - up to 9 m. Such installations are used, as a rule, for small wells or shallow wells. They are used for pumping tanks, basements and other things.
- Submersible pumps are not limited by lift height or other operating characteristics. They are typically used in deep - from 50 m wells with high atmospheric pressure. Normal operation is determined by the power of the unit.
- Installation of various equipment requires compliance with the instructions. A do-it-yourself process is possible, it is only important to take into account the features of the units, the presence of a sufficient water level in the well and the inclusion of an uninterruptible power source in the system.
Installation of a pumping station to the well
It is best to locate the pumping station in a caisson - a special room that reduces the sound of a running engine. Naturally, it must be insulated and waterproofed - low temperatures and humidity are detrimental to the installation.
The station is connected to the well as follows:
- To hold the overall pump, it is strongly recommended to arrange a pedestal on the floor with a rubber backing or a frame with fasteners directly in the wall of the caisson. In the future, the station should not move even a millimeter from its original position, due to vibration during operation. Otherwise, there is a risk of damage from hitting the ground and damage to all equipment beyond repair.
- A coupling is mounted on the cut pipe of the HDPE. A nipple and a check valve are attached to it. Even if the model of the pumping station already contains the last element, the understudy will not be superfluous - it will delay the mass of water from leaving back to the well. At this stage, a coarse filter is also installed at the end of the pipe - it will prevent mechanical suspensions from clogging the station mechanism. Then the pipe is lowered into the well.
- The other end of the pipe is similarly equipped with a coupling for connection to the station. Threaded connections cannot be absolutely reliable, therefore, one cannot do without sealing materials - fum, tangit-unilok, tow. The latter option is already out of use due to its high hygroscopicity - it is impossible to allow stagnation of moisture with the subsequent formation of rust.
- From the outlet of the unit, water pipes are being installed. The nodes will be ball valves, tees, knees - the number depends on the need for several wiring - for irrigation, home, bath and so on. Fittings are brass or plastic - the latter react to temperature changes with cracks, therefore only high-quality raw materials are selected that are inert to weather manifestations.
- The power cable is brought in - the socket should already be brought out into the caisson. The cord may also be long, but this is not very convenient, you will have to constantly step over, step on it, which is fraught with the danger of electric shock. The thickness is determined in advance so that there is no chance of a fracture.
- Water is poured into the pump hole. The quantity is indicated in the assembly instructions. Now the machine is turned on and waiting for the pump to turn off when the desired pressure is reached. If it matches the passport data, then the installation can be considered complete. Otherwise, the settings are made manually - there are special screws in the pressure switch that are responsible for the upper and lower parameters.
It remains to check the operating station for leaks, pressure force and normal circulation in the home wiring.
Installation of a submersible pump to the well scheme
The principle of installing a submersible or deep-well pump is not much different from the general one with a pumping station. There is a difference in the size of the equipment. A submersible pump does not require a special caisson, however, it will still be necessary to equip the head well - a strong cable is attached to it for the subsequent extraction and prevention of the unit.
- The HDPE pipe is cut off. Its size depends on the depth of the well. The unit itself is installed 1.5 m above the bottom so as not to scoop up silt or other dirt from the bottom and 2–3 m below the water table so as not to remain dry if the horizon leaves. The end of the pipe is equipped with a coupling and a check valve. The design is connected to the pump by a double nipple with an external thread.
- Now, along the entire length of the pipe, a power cable is attached with clamps. Electrical tape is also suitable, but metal fasteners are more reliable - the tape is capable of losing adhesive properties during condensate. Fastening frequency - 3 m. The cable cannot be twisted around the pipe - it lies parallel to it. Sufficient length for installation and connection is measured in advance.
- The rope is reinforced. It can be metal or nylon, depending on the weight of the device. For this, there are special lugs on the pump housing. The sections of the cable are connected with a loop and secured with several clamps for reliability. Now the structure can be lowered into the well, carefully, without jerking.
- At the head of the well there is a hole for inserting a water pipe, where it is led out. There is also a safety wire attached. There is always a lightning rod on the head, since the installation is electric.
- It remains to connect the pump to the network, check the pressure and install the plumbing from the outlet pipe.
Thus, two types of pumps from the well are mounted. It is not difficult - with the skills of handling a metalwork tool, the work is familiar. Installation time depends on the timely acquisition of all components - this should be taken care of in advance.
