How to Connect Sprinklers to the House
Installing a sprinkler system includes integrating it using the water to your home. A cost-effective way to do this is by installing a backflow prevention valve, also referred to as an anti-siphon sprinkler valve, in a hose spigot connection. The valve installs where the spigot was eliminated along with a PVC pipe riser from the sprinkler line attaches at the underside of the valve. The very first step is measuring pipe connection seams and obtaining the appropriate valve. Generally, the average do-it-yourself fan can put in the sprinkler valve and connect it into the sprinklers in around an hour.
Measurements and Parts
Switch off the main source valve for water into the home. Open the spigot where the valve will install and permit residual water in the home lines to drain.
Fit a flexible wrench onto the body of the spigot and unscrew the spigot from the pipe fitting in the side of the home.
Measure the diameter of the male nozzle which was twisted to the home connection. Many spigots are designed for 1/2-inch or 3/4-inch pipe. Assess the diameter of the PVC sprinkler pipe riser. Larger sprinkler systems utilize 3/4-inch PVC and more compact systems can use 1/2-inch PVC.
Obtain an anti-siphon sprinkler valve dependent on the sizes of the home connection and PVC riser. If the connection and riser aren’t like diameter, then obtain a 1/2-to-3/4-inch threaded male-female PVC reducer. Incorporate a 6-inch pipe nipple, a 2-inch nipple along with a 90-degree PVC elbow exactly the identical diameter as the home connection. A small roll of vinyl contractor’s tape is all that is needed to seal the few connections when installing the valve.
Wrap vinyl contractor’s tape around both ends of the 2-inch PVC nipple. Screw one end into the vent below the flow-control manage on the sprinkler valve. If a reducer is needed, wrap the 3/4-inch male threads on the reducer with tape, then screw that end into the port and tighten it using adjustable pliers, then bend the 2-inch nipple to the female end of the reducer.
Expand a 90-degree PVC connector onto the open end of the 2-inch nipple. Hold the valve with a single hand. Tighten the elbow clockwise with adjustable pliers, and continue to rotate it clockwise to fully tighten the opposite and also the nipple in the reducer or valve.
Wrap vinyl contractor’s tape around both ends of the 6-inch PVC nipple. Screw one end into the open port on the 90-degree elbow and tighten the nipple using the pliers. Expand the other end to the home connection where the spigot was eliminated. Tighten the nipple clockwise and stop if the sprinkler valve is positioned upright using the open port to get the sprinkler line facing straight down.
Sprinkler Line Structure
Wrap plumber’s tape around the threaded end of a PVC slip-to-thread connector. Expand the finish into the sprinkler-line port in the underside of the valve. Tighten the connector clockwise using the pliers.
Rank the PVC sprinkler riser contrary to the outer side of the valve and mark the riser where it aligns with the top end of the slip-to-thread connector. If necessary, remove soil around the foundation of the riser using a garden spade to position the riser contrary to the valve. Using PVC pipe cutters, cut off the riser where it aligns at the top end of the connector.
Apply PVC cement around the top rim of the riser. Fit the finish fully into the slip-port in the underside of the valve. Fill in any soil that has been removed near the riser and tamp it by foot.
Close off the sprinkler valve utilizing the ball-valve lever above the riser connection. Turn on the main water source to the home. Turn on the sprinkler valve and sprinklers and consent to the directions to correct the flow control setting on the sprinkler valve.
