Hi i have a frost free spigot oustide thats hook up to my garden hose. it always lacks and i didnt know if i had to replace the whole thing or if i can just take it apart and replace a few o rings or whatever. is that even worth it, do they sell repair kits? how would you repair it if you can or do you just replace it? thank you
I am currently working on a frost proof garden spigot myself. I am looking to replace the whole unit. I found out I don't need to as a repair kit was locally avaialble for the anti-siphon valve, which is located on the top of the water valve. The kit was around $4 and super easy to replace and there is a schematic on the back of the package.
I didn't need it, but they offered a valve repair kit for around $7 which include any necessary washers, orings, valve stem/seat, etc. The kit looked almost universal for a variety of models, however manufacturer specific. I would look at your valve and figure out which manufacturer and do an online search. There are plenty of web-based plumbing outfits with parts and also online diagrams.
Mine is a Mansfield and readily avaialable at the local big box stores.
I haven't done a repair, however it looks like you need to remove the handle which gives access to a hex nut fitting that allows removal of the valve stem assembly. IMPORTANT to remember to shut off water supply somewhere upstream and then drain the line.
