An ASSE 1019-A repair kit refreshes the vacuum breaker and handle on a frost-proof wall hydrant so you can stop leaks without replacing the faucet.
What ASSE 1019-A Means For Your Outdoor Faucet
Outdoor wall hydrants that carry the ASSE 1019-A mark are designed for two big jobs: keeping the line from freezing and protecting drinking water from dirty hose water. The standard calls for a built-in check valve and an air inlet so the hydrant can relieve backpressure and stop backsiphonage when a hose is connected and pressure changes.
On a typical frost-proof wall hydrant, the actual shutoff point sits inside the heated side of the wall. When you close the handle, water drains out of the tube and away from the cold exterior. The ASSE 1019-A device adds a vacuum breaker near the hose connection, so yard chemicals, pet bowls, or bucket water at the hose end cannot be pulled back toward the house supply when pressure drops.
The vacuum breaker assembly on an ASSE 1019-A faucet usually sits under a cap at the hose outlet. Inside that cap you will see a small plastic or brass body, an O-ring, a spring, and a float or poppet. When these parts wear out, the hydrant may spray from the top, drip constantly, or fail a backflow test. That is where an ASSE 1019-A repair kit comes in.
An ASSE 1019-A repair kit replaces those wear parts while keeping the main body, copper tube, and interior connections intact. Done correctly, the repair restores freeze protection and backflow protection while saving the cost and mess of opening the wall to swap the entire hydrant.
ASSE 1019-A Repair Kit Lowes Shopping Basics
When you walk into a Lowes plumbing aisle or scan the site, you will not always see “ASSE 1019-A” on every label. Instead, repair parts often appear under categories such as valve repair, vacuum breaker repair part, frost-free sillcock kit, handle and anti-siphon repair kit, or brand-specific wall hydrant repair kit. The goal is to match the thread style, brand, and size of your existing outdoor faucet to the kit on the shelf.
Common kits near the ASSE 1019-A range include handle and anti-siphon repair sets for frost-free sillcocks. These kits usually contain a replacement handle with screw, a vacuum breaker body, and a cap for outdoor faucets that already have an anti-siphon top. Other kits focus only on the vacuum breaker itself, with a cap, inner float, O-ring, and spring for hose bibbs and wall hydrants that drip or spray at the top.
Some repair kits at Lowes carry a specific brand name such as Prier, American Valve, or ReliaBilt. Others work as “universal” vacuum breaker repair parts, often for 4- to 14-inch frost-free sillcocks. The packaging and product page may mention anti-siphon components, frost-free wall faucets, or vacuum breaker repair, even when the ASSE 1019-A code is not printed in large text.
Dedicated ASSE 1019-A repair kits also appear through online sellers. Many describe themselves as outdoor faucet repair kits or vacuum breaker replacement kits for ASSE 1019-A wall hydrants. These often list fine-thread 3/4-inch hose connections and include the cap, internal breaker body, O-rings, spring, and sometimes a new handle. If a local Lowes does not stock a clear ASSE 1019-A match, shoppers often mix an in-store handle kit with an online vacuum breaker kit matched to the exact standard.

For many homes, Lowes offers the fastest route to a working ASSE 1019-A outdoor faucet. The key is to bring information with you: pictures of the faucet, close-ups of the top cap, and any casting numbers on the body or handle. With those in hand, it is much easier to match the right ASSE 1019-A repair kit Lowes has in stock or to decide when to order a branded kit online instead.
Finding An ASSE 1019-A Repair Kit At Lowes
To track down an ASSE 1019-A repair kit at Lowes, start with the valve repair section in the plumbing aisle or the valve repair category on the site. Look for headings that mention vacuum breaker repair part, sillcock repair, or wall hydrant repair rather than only inside shutoff valves. Packaging that mentions anti-siphon components, frost-free faucets, or backflow protection usually belongs in the same family as ASSE 1019-A outdoor taps.
On the shelf, match three details before you buy: the brand, the thread style, and the overall kit style. Many frost-proof hydrants from makers like Woodford, Prier, Arrowhead, and American Valve use fine-thread vacuum breaker caps on a 3/4-inch hose outlet. Others use coarse-thread caps or brand-specific tops that do not accept third-party parts. The cap on your faucet should guide your choice more than the word “universal” on a box.
When you browse the Lowes site, filter by valve repair parts, then by vacuum breaker repair part or sillcock repair. Product descriptions often list whether the kit works with 4- to 14-inch frost-free sillcocks, whether it includes a handle, and whether it restores anti-siphon function. If the kit description describes a vacuum breaker that sits on top of a frost-free sillcock and replaces backflow parts, it likely aligns with the same use case as an ASSE 1019-A repair kit.
- Check For Brand Marks — Look along the wall plate, handle hub, or casting for a brand name or model number you can match to a specific kit.
- Measure Stem Length — If you ever replace the full stem, measure from the back of the wall plate to the tip of the stem so brand-specific kits stay aligned.
- Compare Cap Shape — Hold the picture of your vacuum breaker cap next to product photos so the ridges, slots, and overall shape match closely.
- Read ASSE Language — Scan descriptions for frost-proof wall hydrant, backflow protection, or ASSE 1019 wording to stay with the right performance group.
If your local Lowes only stocks handle and anti-siphon repair kits without a direct ASSE 1019-A note, you can still use them on an existing ASSE 1019-A faucet when the threads, shape, and brand all line up. When none of the kits match, it may be better to order a dedicated ASSE 1019-A vacuum breaker repair kit online or move to a full hydrant replacement that already carries the correct listing.
Step-By-Step ASSE 1019-A Repair Kit Lowes Installation
Once you have the right ASSE 1019-A repair kit Lowes supplied or you sourced online, the repair itself is usually short and tidy. The steps below describe a common layout where the vacuum breaker sits on top of a frost-proof wall hydrant. Always follow the leaflet in your kit if it gives brand-specific directions, and follow local plumbing rules where licensed work is required.
- Shut Off The Supply — Close the indoor shutoff valve feeding the outdoor faucet, then open the outdoor handle to drain pressure from the line.
- Remove The Hose — Unscrew any hose or timer from the hydrant so you can reach the vacuum breaker cap without side load.
- Unscrew The Breaker Cap — Turn the cap on top of the faucet by hand or with an adjustable wrench wrapped in tape to protect the finish.
- Pull Out Old Parts — Lift out the float, spring, O-ring, and inner body from the top of the faucet, keeping track of the order for reference.
- Clean The Seat Area — Wipe away mineral buildup and debris from the metal seat and threads with a cloth or small brush.
- Match New Pieces — Compare each new part from the ASSE 1019-A repair kit to the old part so sizes and shapes line up before installation.
- Lubricate New O-Rings — Apply a thin coat of plumber’s silicone grease to O-rings if the kit documentation allows it.
- Rebuild The Breaker — Drop in the new inner body, spring, and float in the order shown in the diagram, then thread on the new cap by hand.
- Tighten The Cap — Snug the cap until it seats firmly, staying short of crushing the gasket or stripping the threads.
- Restore Water And Test — Open the indoor shutoff, then open and close the outdoor faucet a few times while watching for leaks around the cap.
Many ASSE 1019-A repair kits also include a new handle and handle screw. If your handle is bent, cracked, or stripped, swap it while the system is off. A fresh handle improves grip in cold weather and makes it easier to shut the hydrant fully so the freeze-proof section can drain.
After the repair, attach a hose and run water for a short time. Then close the faucet and watch the vacuum breaker area. A small puff of water at the air inlet as the faucet shuts can be normal. Continuous spray from the cap, a steady drip at the spout, or water inside the house wall points to deeper issues that a kit alone cannot fix.
Troubleshooting Wall Hydrant Issues After A Repair
Even after fitting an ASSE 1019-A repair kit Lowes supplied or one ordered online, some wall hydrants still act up. The behavior of the faucet gives clues about what still needs attention. Pay close attention to where water appears, how fast it leaks, and when noise or spray happens.
Leaks Around The Vacuum Breaker Cap
- Check Cap Tightness — Make sure the cap is snug by hand and that the gasket sits flat instead of pinched or rolled.
- Inspect O-Ring Seating — Remove the cap again and confirm the new O-ring sits in the groove rather than twisted or stretched.
- Look For Cracks — Examine the new cap and inner body for hairline cracks from over-tightening or tool slips.
If the cap still leaks after those checks, the metal seat inside the faucet body may be pitted from years of mineral buildup. No repair kit can restore a deeply scarred seat, so a full hydrant replacement often becomes the better long-term fix.
Drips At The Spout After Shutoff
- Verify Full Shutoff — Turn the handle all the way off and confirm the stem stops firmly instead of hanging in mid travel.
- Check Stem Packing — Look around the packing nut for seepage that might hint at a worn stem packing rather than a vacuum breaker issue.
- Test Without Hose — Remove any hose, sprayer, or timer, then test again to rule out trapped pressure at the hose end.
A steady drip from the spout after an ASSE 1019-A repair kit install usually points to a worn main seat or damaged stem seal. Many brands offer full stem repair kits that pair well with a vacuum breaker kit. When stems are no longer available, replacing the hydrant body becomes the cleanest route.
Noisy Operation Or Poor Flow
- Flush Debris — Open the faucet fully without a hose attached to wash out chips or grit that may lodge in the new breaker parts.
- Check Breaker Orientation — Confirm the float and spring sit in the order shown in the instructions, since reversed parts can chatter or restrict flow.
- Confirm Supply Pressure — Compare flow at another faucet to make sure a pressure drop is not coming from the main line or pressure regulator.
A wall hydrant in good shape should deliver steady flow and then drain once shut off. If chatter, rattling, or sharp pressure swings continue after repairs, a licensed plumber can check system pressure, backflow assemblies, and regional code requirements around outdoor faucets and hose connections.
When To Replace The Wall Hydrant Instead Of Repairing
An ASSE 1019-A repair kit Lowes sells or an online source supplies can solve many outdoor faucet issues, but some hydrants reach a point where more parts do not help. Age, freeze damage, and repeated makeshift repairs all take a toll on the tube inside the wall and the main seat. At that stage, a new ASSE 1019-A wall hydrant is often the better investment.
- Split Or Bulged Tube — If water appears inside the wall or you can see a bulge on the copper tube, the frost-proof section has failed and should be replaced.
- Badly Corroded Body — Heavy scaling, green corrosion, or thin metal around the hose outlet can keep new vacuum breaker parts from sealing.
- Obsolete Or Unknown Model — When brand and model markings are gone, finding a safe ASSE 1019-A repair kit match becomes guesswork.
- Failed Backflow Test — If a tester reports that the hydrant cannot maintain backflow protection even with new parts, replacement keeps the system safer.
Modern frost-proof wall hydrants listed to ASSE 1019 often come with improved vacuum breaker designs, better materials, and clear labeling on the casting and packaging. Many are sold at big-box stores as complete assemblies in several lengths, matched to common wall thicknesses. A new hydrant does require opening a section of wall or reaching through a rim joist, yet it also resets the clock on freeze resistance and backflow protection.
Whichever route you choose, match your repair or replacement to local plumbing rules. Outdoor faucets are more than just garden taps; under many codes they form part of the backflow protection strategy for the whole water supply. A well-chosen ASSE 1019-A repair kit Lowes provides or a new listed hydrant helps keep that system in line while keeping your outdoor faucet easy to use through every season.
