How To Fix a Water Leak in the Anti Siphon Valve of an Outdoor Faucet

hey guys got here with everyday home repairs and moving to the outdoors it is it's warming up quite a bit here and I've kind of been putting off a really simple repair for for the last couple of years I'm sure that's never happened to any of you but I'm not sure why this one's taking me so long but I'll show you how to fix it it's a quick and easy one what's going on is this outdoor faucet or spigot the top anti-siphon valve or vacuum brake valve when you turn it on we get leaking out of the top of that valve so what's happening is there is a small kind of plunger that goes up and down there when you turn it on it should seat no water should come out but then when you turn it off it does let air go back through and creates a flow path so you don't get kind of a siphon effect which would pull water back in to the clean water supply so a few things this can be just some debris or something in that small little plunger preventing it from seating correctly in the small casing or there could be some other just malfunction it's pretty cheap part so this thing does can go kind of in and out so I'll show you how to kind of pop off that cap pull it out and then I'll show you a repair kit or also just how to look at the part that you currently have to see maybe if you can just do the fix by removing some debris okay so here we are at the outdoor spigot again I'll show you the where the leaks coming from so you can see out of the cap here the leaks coming around so we're getting quite a bit of water flowing out which we don't want it's going right on the foundation and it's not helping this concrete slab loosening up the under footing so what we do is pop this off just with a flathead this one's really loose so this one's really easy to pop off you might have to work your side to side but this one's gonna be real easy to to take off there that one's so easy to take off because there is some kind of plastic missing here on that piece so now I'll just take some channel locks again we might want to reuse this part so take your time and try not to smash that plastic part because if you do you could you could damage one of these components that you could reuse after removing some debris okay so so really simple right there's that plunger that we talked about and kind of that outer casing what you can do is turn on and flush out so flush out any debris kind of let that water come out at the top and then that will make sure there's no debris within the threads here within the spigot and then what I'm going to do is just gonna pop out a little plunger okay so that is the little seal if you look at mine is kind of discolored looks to be a little oblong and and really because it has that cone shape here it's only it's only gonna see on that little edge there to the plastic top there so what I'm gonna do is I'm gonna just swap out the kit so what I got here is just a replacement kit again anti-siphon valve they call it though a vacuum breaker valve so it comes with a casing that plunger there and then the cap so go ahead and open this guy up now you can get these at most big-box stores Home Depot's Lowe's we got from Menards if not all so we'll put a link in the description you can get you can get them online as well from Menards so all we're gonna do is place that little plunger within the casing okay so if it falls out like that make sure it does seat well as you screw this in so I'm gonna probably pop that back out and make sure it all right then just of course hand tighten it should be pretty easy at I do not do not overtighten this again it's just plastic so you can easily break the casing so really just get it snug in there just another quarter turn or so and even before the cap you should be able to turn this on and you should see that plunger go up let's get a little closer look there I see that plungers is down I turn the water on and that plunger goes up okay yep so you can see that will block the water and then it goes back down and that's what allows that airflow path to open back up to make sure there's no siphon on the spit get pulling back through a hose or depending on if there's a vacuum pulled through your through your water line and then just replace the cap here and believe it or not is that that easy that's it now we got a little water leak still kind of coming out of the hose here that we might address but at least now the the anti siphon or vacuum brake valve is good to go all right now we got the anti-siphon valve swapped out that leak is fixed I am gonna check out that handle a little bit I saw some additional water coming out of that so if I find anything there I'll also share that one with you guys a few tips before you buy the replacement k go ahead and go out to your spigot and pop that cap off and take take the valve out to see it could be just some debris that's not allowing that plunger to go up and down like I showed you that could be a really easy kit a really easy fix and that kid I think is like eight to ten dollars so that might save you a little money so check it out first and also you'll check it out to see if that's the same construction valve that you have there are a few others on the market I think my cap said Mansfield so I believe that's the brand of this one so just check it out before you do it save yourself some time and then possibly some money so that's it again my name is Scott from everyday home repairs if you like these type of videos don't forget to subscribe and then also look in the description if you want to know exactly what kid I got I'll put a link there so thanks for joining
