Why Is My Faucet Leaking?

Common Causes of Faucet Leaks in Phoenix Homes 

If your faucet is dripping, leaking around the handle, or leaving water under the sink, it’s trying to tell you something. In many cases, a leaking faucet starts as a simple repair — but if ignored, it can quickly turn into a full faucet replacement. 

At Robins Plumbing, Inc., we speak homeowner. That means we help you understand why your faucet is leaking, what may have caused it, and when it’s time to repair versus replace. Our goal is to educate and empower homeowners while providing a higher level of service throughout the Phoenix area. 

Why Do Faucets Leak? 

There are several common reasons faucets begin to leak, especially here in Phoenix where hard water and high water pressure are common issues. 

Age and Normal Wear 

Like anything mechanical in your home, faucets wear out over time. Inside every faucet are moving parts, seals, cartridges, washers, and O-rings that experience constant use. 

Older faucets often begin leaking because: 

• Rubber seals dry out or crack 

• Internal cartridges wear down 

• Metal components corrode 

• Threads and connection points loosen over time 

Sometimes a repair is all that’s needed. Other times, the faucet has simply reached the end of its lifespan. 

High Water Pressure Can Damage Faucets 

Many homeowners don’t realize that excessively high water pressure can slowly destroy plumbing fixtures. 

When water pressure is too high, it places constant stress on: 

• Faucet cartridges 

• Supply lines 

• Internal seals 

• Valves and connection points 

Over time, that stress can cause leaks around the handle, base, or spout of the faucet. 

In Phoenix, pressure issues are extremely common, especially in homes without a properly functioning pressure reducing valve (PRV). 

Signs Your Water Pressure May Be Too High 

• Faucets dripping frequently 

• Banging pipes 

• Toilets running often 

• Appliances failing prematurely 

• Sudden plumbing leaks 

• Water hammer noises 

If your faucets repeatedly fail, your home’s water pressure may be the real problem. 

Hard Water Is Extremely Tough on Faucets in Phoenix 

Phoenix is known for very hard water, and hard water quietly destroys plumbing fixtures from the inside out. 

Mineral buildup from calcium and magnesium can: 

• Damage faucet cartridges 

• Restrict water flow 

• Cause handles to stick 

• Prevent seals from sealing properly 

• Corrode internal faucet parts 

• Leave crust buildup around the spout and handles 

Hard water buildup doesn’t just affect appearance — it shortens the lifespan of your faucet. Over time, minerals can permanently damage the internal body of the faucet, making repairs less effective or impossible. 

Defective or Worn Internal Parts 

Sometimes the faucet itself is still in good shape, but the internal repair components have failed. 

Common faucet parts that fail include: 

• Cartridges 

• O-rings 

• Seats and springs 

• Washers 

• Valve stems 

A professional plumber can often diagnose whether the faucet can still be repaired or if replacement makes more financial sense. 

Why You Shouldn’t Ignore a Leaking Faucet 

One of the biggest mistakes homeowners make is waiting too long to repair a leaking faucet. 

A small drip may seem harmless, but water leaking through worn internal parts can slowly damage the inside of the faucet body itself. 

As water continues leaking: 

• Mineral deposits build up 

• Corrosion forms inside the faucet 

• The sealing surfaces become etched and damaged 

Once the faucet body becomes etched, new repair parts may no longer seal properly for the long term. 

That means what could have been a relatively simple repair may eventually require full faucet replacement. 

Can a Leaking Faucet Increase My Water Bill? 

Absolutely. Even a slow drip can waste a surprising amount of water over time. Multiple leaking fixtures throughout a home can significantly increase monthly water usage and utility costs. 

More importantly, leaks under sinks can also cause: 

• Cabinet damage 

• Mold growth 

• Wood rot 

• Water staining 

• Damage to flooring and walls 

Should I Repair or Replace My Faucet? 

That depends on several factors, including: 

• Age of the faucet 

• Brand and repair part availability 

• Severity of corrosion or hard water buildup 

• Condition of the faucet body 

• Overall cost effectiveness 

At Robins Plumbing, Inc., we help homeowners understand their options so they can make informed decisions without pressure. 

Sometimes a repair is the best value. Other times, replacement saves money and frustration long term.

Suggested FAQ Section 

Can hard water cause faucets to leak? 

Yes. Phoenix hard water can damage cartridges, seals, and internal faucet components, leading to leaks and premature fixture failure. 

Is a leaking faucet always repairable? 

No. If the faucet body becomes etched or corroded from long-term leaking or mineral buildup, replacement may be the better option. 

Can high water pressure damage faucets? 

Absolutely. Excessively high pressure puts stress on faucet components and can shorten the lifespan of plumbing fixtures throughout the home. 

How do I know if I need a new faucet? 

If your faucet leaks repeatedly, has severe corrosion, poor water flow, or repair parts no longer seal properly, replacement may be recommended.
