The well screen is the most important part of the well: it attaches to the bottom of the long PVC well pipe and lets the water in, filtering out debris and sand. The well screen has hundreds of small slits that filter out the debris, keeping your water clean. There will be a 4 inch (10.2 cm) space between the bottom of the 8 inch (20.3cm) PVC pipe where there are no slits. This 4 inches (10.2cm) gap will connect to the the PVC pipe. Mark three slits circumferentially around the 8 inch (20.3cm) pipe. The slits should be approximately 7 inches (17.8cm) long and should be equally spaced apart. The gap between each slit should be approximately 1.4 inches (3.5 cm). Make sure your slit does not connect all the way around the pipe. Leave a small gap between the ends of each slit. Draw three more slits two inches above the first set of slits. Again, make sure that the slits don't wrap all the way around the screen, but instead have a gap of two inches between ends of the slits. Keep drawing sets of three slits, all two inches apart. You can stop when the the screen reaches 6 feet (1.8m) in length. The length of six feet will allow a great deal of water to come through the pipe and be filtered. Using a hacksaw, cut out the slits according to the lines you drew. Carefully saw each line, making sure not to cut all the way through the pipe. Continue sawing until you have made a slit for every line. You'll need to find a PVC cap to the end of the well screen. Make sure that it fits the well screen snugly. Any leakage here, and your well will not filter properly. The primer will help hold the end cap onto the screen and prevent any leakages. Apply the primer liberally to avoid any leaks. Once you've applied the primer to the end cap, turn to the well screen. Apply the same amount of primer around the mating portion of the well screen. The double portion of primer will help both pieces to hold together. You'll have to work quickly here, as the cement dries quickly. Paint over the exact area that you primed. Again, work quickly. Hold the end cap onto the screen for fifteen seconds to allow the cement to dry. Let the pipe rest for several minutes to ensure that the glue has dried completely. The foot valve is the mechanism that allows water to be drawn in but does not allow water to escape back out. There are two-foot valves used in this well. The first one is at the bottom of the six-inch PVC pipe and the second one is at the bottom of the 4 inch (10.2cm) PVC. These mechanisms will allow the water to be drawn into the 6 inch (15.2cm) pipe on the upstroke of the well, and it will push water through the 4 inch (10.2cm) pipe on the down stroke, when water is pushed out of the well.
