The installation of the electricity, the water pipes, the underwater lighting, pump, sand filter, solar collectors and all other necessary components you need to install a pool are discussed in this video.

You can see how all the power cables are in the ground for the power supplies in the shed and the pump cabinet. The LED pool lighting is connected to a transformer in the shed.

After laying the ground cables and installing the electrical components I started installing the water pipes. This video shows how the water flows through the closed water circuit.
The heart of the closed water circuit is the pump in the pump cabinet, once switched on, it will draw water from the pool through the skimmer. the water then passes through the pre-filter and the pump then pushes the water to the sand filter. Filtered water is then pumped to the injectors in the pool. At least, that's the case if the water has the right temperature.
I built a bypass in the pump cabinet, which contains 3 ball valves with which I can lead the water to the solar collectors on the roof terrace when the water needs to be heated.
The solar collectors absorb the heat from the sun and then transfer that heat to the water that flows through the solar collectors. The heated water will then flow back into the pool through the bypass through the injectors.

Two other ball valves, before the pump, can be used to control where the water is drawn from the pool. From the skimmer or bottom of the bottom suction connection. The water goes through the skimmer with the normal standard filter operation. If the bottom of the pool needs to be cleaned, the ball valves can be used to set the water from the bottom suction connection to be sucked into the pool. A hose and a vacuum cleaner can be connected at that point.

I also installed a non-return valve in the pump cabinet, between the skimmer and the pump.
With the normal standard filter operation, this valve lets water through. However, as soon as the pump is switched off, the non-return valve will close immediately. This prevents slow water from flowing back to the pool. If there was a small hole somewhere in the water circuit that is above the surface water of the pool, however small, that could happen. Without a non-return valve, starting the pump will be accompanied by a lot of noise because the pump will suck in air instead of water. There are also air bubbles in the water pipes that are eventually blown out of the injectors with a lot of gurgling and noise. It then takes quite a long time before all the air is gone and the filtering works properly again.
