There\u2019s no need to call a plumber and spend a couple of hundred dollars to have him\/her fix it. With about five minutes of effort, and for less than ten dollars, you yourself can replace an anti-siphon valve on an outdoor faucet.<\/span><\/p>\n<table style=\"width: 100%;\">\n<tbody>\n<tr>\n<td style=\"text-align: left;\" width=\"50%\">\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\"><strong>Steps for Replacing the Anti-Siphon Valve on an Outdoor Faucet<\/strong><br \/>\n<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">The first step in replacing an anti-siphon valve is to turn water off to the outdoor faucet. Typically, you will find a valve inside the home, such as in the basement, that is associated with the outdoor spigot. Turn this valve off and then go out and turn the handle wide open on the outdoor spigot to confirm the water is no longer flowing out of it.<\/span><\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"47%\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-18555\" src=\"http:\/\/homeadditionplus.com\/dev\/wp-content\/uploads\/2018\/05\/anti-Siphon_valve_outdoor_spigot-300x167.jpg\" alt=\"anti-Siphon valve outdoor spigot\" width=\"300\" height=\"167\" srcset=\"https:\/\/homeadditionplus.com\/dev\/wp-content\/uploads\/2018\/05\/anti-Siphon_valve_outdoor_spigot-300x167.jpg 300w, https:\/\/homeadditionplus.com\/dev\/wp-content\/uploads\/2018\/05\/anti-Siphon_valve_outdoor_spigot.jpg 551w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">Next, using a common screwdriver or a nut and ratchet set remove the screw that holds the outdoor faucet handle onto the faucet. This will allow you to have easier access to the anti-siphon valve.<\/span><\/p>\n<table style=\"width: 100%;\">\n<tbody>\n<tr>\n<td style=\"text-align: left;\" width=\"50%\">\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">Now, using the common screwdriver, carefully pry the cap off of the anti-siphon valve to expose the valve itself.<br \/>\n<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">Then, preferably using just your fingers, unscrew the plastic valve body assembly from the metal outdoor faucet. You may have to use a pair of adjustable pliers. If you do, try to be careful not to break the anti-siphon valve body, not that you are going to use it again. It just can be more difficult to unscrew it if it is broken with the pliers.<\/span><\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"49%\"><a href=\"http:\/\/homeadditionplus.com\/dev\/ebooks\/how-to-install-a-faucet-ebook\/\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-6707\" src=\"http:\/\/homeadditionplus.com\/dev\/wp-content\/uploads\/2016\/12\/Installing-a-New-Faucet-Ebook-252x300.jpg\" alt=\"How to Install a New Faucet Ebook\" width=\"252\" height=\"300\" srcset=\"https:\/\/homeadditionplus.com\/dev\/wp-content\/uploads\/2016\/12\/Installing-a-New-Faucet-Ebook-252x300.jpg 252w, https:\/\/homeadditionplus.com\/dev\/wp-content\/uploads\/2016\/12\/Installing-a-New-Faucet-Ebook-768x916.jpg 768w, https:\/\/homeadditionplus.com\/dev\/wp-content\/uploads\/2016\/12\/Installing-a-New-Faucet-Ebook-859x1024.jpg 859w, https:\/\/homeadditionplus.com\/dev\/wp-content\/uploads\/2016\/12\/Installing-a-New-Faucet-Ebook.jpg 955w\" sizes=\"auto, (max-width: 252px) 100vw, 252px\" \/><\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">Next, using your screwdriver remove the small screw that holds the spigot handle to the faucet assembly.<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">Now remove the handle from the faucet.<\/span><\/p>\n<table style=\"width: 100%;\">\n<tbody>\n<tr>\n<td style=\"text-align: left;\" width=\"50%\">\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">Once you\u2019ve unscrewed the old anti-siphon valve body from the outdoor faucet, screw in the replacement anti-siphon valve body using your fingers.
