Hose Bib Repair in Keller TX: Fixing Outdoor Faucets After a Freeze and Upgrading Before the Next One

It is May. The hose bib on the south side of the garage has been dripping since January, when the temperature dropped to 8°F overnight and you forgot to disconnect the hose. You noticed it in February. You told yourself you would deal with it in spring. Now it is spring.

The hose bib is dripping because the freeze cracked the seat washer inside the valve body. Every time you turn on the outdoor faucet, water gets past the damaged washer. The drip looks minor. At even a slow drip rate, it is wasting 3 to 15 gallons per day — and over summer months of daily outdoor water use, it is also wasting money on every water bill.

The repair is straightforward. The smarter move, while Ricky is already there, is to replace the standard compression hose bib with a frost-free sillcock — a design that keeps the valve mechanism inside the heated wall cavity rather than at the exterior face, eliminating the freeze failure point permanently for that faucet.

What January Does to Keller Hose Bibs

North Texas does not have mild winters. It has long stretches of warm weather interrupted by sudden, violent cold events. When a hard freeze arrives — the NOAA climate normals for DFW document that temperatures in the Dallas-Fort Worth region can drop more than 40 degrees in 24 hours — outdoor hose bibs are among the first plumbing components to fail.

The reason is specific to standard compression-style hose bibs, which are still common on Keller homes built before 2000. A compression hose bib has its valve mechanism at the exterior face of the wall, directly exposed to outside air. When temperatures drop below freezing, any water remaining in the valve body freezes and expands. If a garden hose was left connected, it blocks the valve from draining and the ice expansion has nowhere to go. The seat washer — the rubber disc that creates the seal when the faucet is closed — cracks under the pressure.

When temperatures rise and the ice thaws, the cracked washer allows water to pass every time the faucet is opened. The faucet turns on fine. It just does not fully shut off.

A Real Call: The April Drip That Started in January

Tom called in mid-April from his home in Keller’s Stone Crossing neighborhood. The back hose bib had been dripping since he thawed it in January. He had been using it through spring — it ran fine, it just dripped afterward. He had left a bucket under it.

Ricky arrived and turned on the hose bib. Full flow, no restriction. Turned it off. Drip immediately resumed at about 5 to 8 drips per minute.

The seat washer was cracked — the classic freeze-damage finding on a standard compression hose bib. The faucet was original to the home’s 1994 construction, a standard 3/4 inch compression valve. Thirty-one years old.

Ricky gave Tom two options. Option one: replace the seat washer — a 30-minute repair that stops the drip for another few years, on a 31-year-old compression valve that will face the same freeze risk every January. Cost: $150 to $195. Option two: replace the entire hose bib with a frost-free sillcock — the valve mechanism moves inside the wall, the freeze failure point is eliminated, and a new brass frost-free hose bib has a 20-plus year service life. Cost: $280 to $480.

Tom chose the frost-free replacement. The old compression valve had already cracked once. A 30-year-old compression valve in North Texas will crack again.

Standard vs Frost-Free: What the Difference Means for Keller Homes

Understanding the difference between the two hose bib types explains why most Keller homes benefit from the frost-free upgrade.

Standard compression hose bib: The valve mechanism — the seat washer and stem — sits at the exterior face of the wall. When the faucet is closed, standing water remains in the valve body and the short pipe stub between the exterior wall and the interior shutoff valve. In a freeze event, that standing water freezes and can crack the seat washer or the valve body. The freeze risk is present every January in North Texas regardless of how cold the specific event is.

Frost-free sillcock (frost-free hose bib): The valve mechanism is located 6 to 10 inches behind the exterior wall, inside the heated wall cavity. The exterior pipe stem is just a tube — there is no valve mechanism at the exterior face. When the faucet is closed, the long stem retracts and the standing water in the stem drains back into the wall cavity by gravity. There is no water sitting at the exterior face to freeze.

This design eliminates the primary freeze failure mode for Keller hose bibs. The critical caveat: a frost-free hose bib still fails if a garden hose is left connected during a freeze. A connected hose creates backpressure that prevents the water in the stem from draining. The water stays in the stem, freezes, and the failure is the same as a standard hose bib. The rule is simple: disconnect all garden hoses before any forecasted hard freeze, regardless of hose bib type.

Texas Anti-Siphon Requirement

All outdoor hose bibs in Texas must have anti-siphon protection. This is a plumbing code requirement, not a recommendation. The anti-siphon valve prevents a backflow event — a scenario where a drop in supply pressure could allow contaminated outdoor water (from a pesticide sprayer, a bucket of fertilizer solution, an attached hose sitting in a puddle) to be drawn back into the home’s potable water supply.

Many frost-free sillcocks come with an integrated anti-siphon valve — Ricky confirms this is present in the unit installed. Some older Keller homes have hose bibs that were installed before the requirement was consistently enforced and lack anti-siphon protection entirely.

On any hose bib replacement, Polly Plumbing installs a unit that meets the current Texas code requirement. If an older hose bib is being repaired rather than replaced, Ricky notes whether an anti-siphon valve should be added.

Every Common Hose Bib Problem and Its Fix

Dripping After Shutoff (Most Common Spring Finding)

Cause: Cracked or worn seat washer, usually from freeze damage. The washer cannot fully seal against the valve seat.

Fix: Washer replacement or full hose bib replacement. For a hose bib less than 10 years old in good condition: washer replacement. For a hose bib 15 or more years old on a Keller home: replacement with a frost-free unit is the more cost-effective long-term solution.

Cost: Washer repair $150 to $195. Full frost-free replacement $280 to $480.

Will Not Fully Shut Off (Water Continues to Flow)

Cause: The stem or seat has been damaged, often from overtightening over years of use, or from a freeze event that cracked the valve body.

Fix: Full hose bib replacement. A valve body that has been overtightened or cracked cannot be reliably restored to a fully functional shutoff.

Cost: $280 to $480 for frost-free replacement.

Handle Hard to Turn

Cause: Mineral scale from Keller’s hard water accumulating around the stem threads, or corrosion on an older brass or galvanized valve body. This is the same hard water mechanism that affects shower cartridges and faucet cartridges — just applied to the outdoor valve.

Fix: For minor stiffness: the stem threads can be cleaned and lubricated. For severe corrosion or if the handle is at risk of breaking during operation: replacement.

Cost: $80 to $150 for cleaning and lubrication. $280 to $480 for replacement.

Leaking From the Wall or Handle Area (Not From the Spout)

Cause: A failed stem packing — the seal around the valve stem behind the handle. Water is bypassing the packing and coming out around the handle base or into the wall cavity.

Fix: Packing replacement if the valve body is otherwise in good condition. For older units: replacement.

Cost: $150 to $250 for packing replacement. $280 to $480 for full replacement.

Outdoor Faucet Runs But Pressure Is Very Low

Cause: Mineral scale clogging the aerator screen (if present) or a debris blockage at the inlet screen. In rare cases, a failing interior shutoff valve that is not fully open.

Fix: Check and clean the inlet screen at the hose bib connection. Confirm the interior shutoff is fully open. For whole-house low pressure see our low water pressure guide for Keller TX.

Adding a New Outdoor Hose Bib

Many Keller homes — particularly older construction on larger lots — have only one or two outdoor hose bibs, often positioned for the original 1970s or 1980s landscaping layout that no longer fits how the yard is used. Adding a new hose bib on the back patio, the side yard, or the garage wall is a common spring project.

A new outdoor hose bib requires: a connection to the nearest interior supply line, a hole through the exterior wall, the frost-free sillcock installation, and an interior shutoff valve added at the connection point. In most Keller homes with accessible wall cavities, this is a one-day project.

Cost: $350 to $650 for a new hose bib installation depending on the distance from the nearest interior supply and wall material. All new installations include the required Texas anti-siphon protection.

How to Winterize Your Keller Hose Bibs Before Next January

Annual winterization takes 15 minutes and prevents the repair call in April.

For standard compression hose bibs: Locate the interior shutoff valve for each outdoor faucet — typically in the garage or utility room on the interior wall behind the exterior faucet location. Turn the interior shutoff fully closed. Then open the exterior hose bib handle and leave it open to drain any residual water from the valve body and the pipe stub between the shutoff and the exterior face. Disconnect all garden hoses. Leave the exterior handle open until spring.

For frost-free sillcocks: The interior shutoff step is not required for the valve itself since the mechanism is inside the heated wall. The critical step: disconnect all garden hoses before any forecasted hard freeze. A hose left connected traps water in the stem and recreates the exact freeze failure the frost-free design was meant to prevent.

Frequently Asked Questions About Hose Bib Repair in Keller TX

Why is my Keller TX outdoor faucet dripping after the January freeze?

The seat washer inside the valve cracked when water froze in the faucet body during the hard freeze. A connected garden hose blocks the valve from draining, trapping water that then expands when it freezes and damages the washer. The faucet turns on normally but the cracked washer cannot fully seal when closed. Washer replacement stops the drip. Upgrading to a frost-free sillcock eliminates the freeze failure point permanently. Call Polly Plumbing at (817) 286-3446.

How much does hose bib repair cost in Keller TX?

Seat washer replacement runs $150 to $195. Stem packing replacement runs $150 to $250. Frost-free hose bib replacement at an existing location runs $280 to $480. New hose bib installation at a new location runs $350 to $650. Anti-siphon valve addition runs $95 to $175. The $89 dispatch fee is waived for PollyCare members. Written quote before any work begins. Call Polly Plumbing at (817) 286-3446.

What is a frost-free hose bib and do I need one in Keller TX?

A frost-free sillcock places the valve mechanism 6 to 10 inches inside the heated wall cavity rather than at the exterior face. When the faucet is closed, water drains from the stem by gravity and nothing is left at the exterior to freeze. This eliminates the primary freeze failure mode for Keller outdoor faucets. Most Keller homes built before 2000 have standard compression hose bibs that are candidates for frost-free replacement. Always disconnect garden hoses before a freeze even with a frost-free unit — a connected hose prevents the stem from draining. Call (817) 286-3446.

Does Texas require an anti-siphon valve on outdoor hose bibs?

Yes. Texas plumbing code requires anti-siphon protection on all outdoor hose bibs. The anti-siphon valve prevents contaminated outdoor water from being drawn back into the home’s potable water supply during a pressure drop event. Many frost-free sillcocks include an integrated anti-siphon valve. Polly Plumbing installs code-compliant units on every hose bib replacement in Keller. If an older unit lacks anti-siphon protection, Ricky can add a vacuum breaker at the same visit. Call (817) 286-3446.

How do I prevent my Keller TX hose bib from freezing next winter?

For standard compression hose bibs: close the interior shutoff valve for the outdoor faucet, then open the exterior handle to drain the valve body and pipe stub. Leave the exterior handle open until spring. For frost-free sillcocks: disconnect all garden hoses before any forecasted hard freeze. The frost-free design handles the rest automatically — but a connected hose traps water in the stem and recreates the freeze failure the design was meant to prevent. For the full freeze prevention checklist see our burst pipe repair guide for Keller TX.

Can I add a new outdoor hose bib to my Keller TX home?

Yes. Polly Plumbing installs new outdoor hose bibs at new locations — back patios, side yards, garage walls, and any exterior wall location where a supply line can be tapped. A new installation requires a connection to the nearest interior supply line, a hole through the exterior wall, and a frost-free sillcock with anti-siphon protection. Cost: $350 to $650 depending on wall access and distance from the supply line. Call (817) 286-3446.

How long does a hose bib last in Keller TX?

A quality frost-free brass sillcock lasts 20 to 30 years with annual disconnection of hoses before freezes. Standard compression hose bibs in Keller last 15 to 20 years but are vulnerable to a freeze failure at any point when a hose is left connected. Keller’s hard water at 15 to 25 GPG adds minor mineral scale to the stem threads over years but is less damaging to outdoor hose bibs than to indoor fixtures because outdoor faucets are typically not in constant daily use.
