The best anti-siphon valve kit depends on the brand and model of your outdoor faucet: Homewerks suits compatible traditional frost-free sillcocks, Ceoighe targets specified Legend valves, and the Eastman-specific kit is intended for model 45417. For broader ASSE 1019-A-style replacements, compare the PILISPARK and GEGEHANSEN kits carefully with your existing parts. Matching the valve style and dimensions before buying is essential.
| Kit | Best For | Key Difference |
|---|---|---|
| Homewerks VACVBKX1B | Traditional frost-free sillcocks | Includes cap, body, plunger, and seals |
| Ceoighe 2 Pack | Specified Legend T550 and T550A valves | Two sets of replacement parts |
| lasuroa for Eastman 45417 | Eastman faucet model 45417 | Model-specific component set |
| GEGEHANSEN | VACVBKX1B-style replacements | Two body sizes included |
| PILISPARK ASSE 1019-A | ASSE 1019-style valve repairs | Plastic body, plunger, and O-ring |
Homewerks VACVBKX1B Replacement Kit
This kit is best for owners repairing a compatible traditional anti-siphon, frost-free sillcock. It includes a vacuum breaker cap, plastic body, plunger, O-ring, and plunger seal, so the listed parts support a component replacement rather than replacement of the entire outdoor faucet. Its vacuum breaker is designed to help prevent contaminated water from siphoning back into the home’s clean water supply.
Why it was selected: The product is a clearly identified replacement kit for traditional anti-siphon frost-free sillcock valves and specifies its included components. Check before buying: Confirm that your faucet uses this style; the listing does not establish compatibility with every outdoor faucet.
Ceoighe Two-Pack For Legend Valves
Choose this two-pack if your faucet uses Legend Valve LEG-108-903 components for a T550 or Improved Flow T550A frost-free faucet. The stated applications cover faucet lengths of 4, 6, 8, 10, 12, and 14 inches. Each set includes a cap, body with rubber O-ring, and piston. The product describes its cover as plated brass and press-on rather than screw-in.
Why it was selected: Its model-specific fit information and two sets make it a practical option for buyers who need that exact Legend-compatible style or want a spare set. Check before buying: Avoid choosing it solely because your faucet is frost-free; verify the valve model and the original part shape.
lasuroa Kit For Eastman 45417
This kit is best for a repair involving an Eastman 45417 faucet. Its listed contents are one vacuum breaker cap, one plunger, and one vacuum breaker body. The stated materials include zinc alloy, rubber, and plastic, and the product is presented for outdoor faucet maintenance.
Why it was selected: The listing names a specific faucet model, making it easier to assess fit when that model matches the existing faucet. Check before buying: The stated compatibility is limited to Eastman 45417; do not assume it fits other Eastman models or other brands.
GEGEHANSEN Kit With Two Body Sizes
GEGEHANSEN is best for buyers looking for a replacement described as matching standard VACVBKX1B models. The kit includes two main body sizes, listed as 0.8 inch and 0.85 inch, along with brass caps, bodies, plungers, and O-rings. The listing also describes the kit as an ASSE 1019-A-style replacement.
Why it was selected: Having two body sizes gives buyers a way to compare the included parts with an existing assembly. Check before buying: Measure the original body and verify the valve style; the two sizes do not guarantee a fit for every spigot.
PILISPARK ASSE 1019-A Repair Kit
This kit is best for buyers seeking replacement core parts for a compatible ASSE 1019-style valve. It includes a decorative cover, plastic body, plunger, and O-ring. The manufacturer describes the body as rust-proof ABS plastic and says the valve is designed to help block reverse siphonage when water pressure drops.
Why it was selected: The listing identifies the valve standard and the core repair components, which helps buyers compare it with an existing assembly. Check before buying: “Universal” application language does not confirm a match for every faucet. Compare the original valve and parts before ordering.
Buying Guide: How To Choose An Anti-Siphon Valve Kit
How do I check whether a kit fits?
Start with the faucet brand and model, then compare the existing vacuum breaker’s shape, dimensions, and attachment style with the product details. A kit described for a specific model, such as Eastman 45417 or Legend T550/T550A, is not automatically suitable for a different faucet. For general ASSE 1019-A-style kits, use the standard as a starting point, not a substitute for checking physical fit.
Which parts should a repair kit include?
Look at the parts that are worn, missing, or leaking. Kits in this selection include combinations of caps, bodies, plungers or pistons, O-rings, and seals. A kit with several components can support a more complete replacement of the listed vacuum breaker parts. Compare the package contents with the parts removed from your faucet.
Should I choose plastic or metal components?
These products use different materials, including plastic, rubber, zinc alloy, and brass or plated brass. Material alone does not establish fit or service life. Prioritize the correct model and body size, then check the product’s stated materials and included seals to ensure the kit matches your repair needs.
Why replace the vacuum breaker?
An anti-siphon vacuum breaker helps reduce the risk of water flowing backward into the potable supply when pressure changes. A damaged or worn assembly may also be associated with leaking around the outdoor faucet. A repair kit replaces specified components; it is not a guarantee that every leak or plumbing issue will be resolved.

In these listings, the terms describe repair kits for vacuum breaker components in anti-siphon outdoor faucet assemblies. Check the specific product’s stated application and fit details.
Can I use one kit for any outdoor faucet?
No. Compatibility varies by faucet model, valve design, and part dimensions. Confirm the existing assembly before selecting a kit.
Does replacing the kit replace the whole sillcock?
These products are described as replacement parts for the vacuum breaker assembly, not as complete outdoor faucets or sillcocks.
What should I compare before ordering?
Compare the faucet model, valve style, body size, cap attachment, and the included components with your original parts.
