Leaky Faucets — The #1 Plumbing Call

A dripping faucet is the most common plumbing complaint we hear from homeowners in Arroyo Grande and the Five Cities. While it might seem minor, a faucet dripping once per second wastes approximately 3,000 gallons of water per year — that's real money on your water bill.

What Causes Leaky Faucets?

The most common causes are worn-out cartridges, O-rings, or valve seats inside the faucet body. Hard water (which is common on the Central Coast) accelerates this wear by depositing minerals on internal components. Age is also a factor — most faucet cartridges last 5–10 years before needing replacement.

How Long Does the Repair Take?

A professional faucet repair typically takes 30–60 minutes. This includes shutting off the water, disassembling the faucet, replacing the worn component, reassembling, and testing. In some cases, if the faucet body itself is corroded or cracked (as we sometimes find with older fixtures), a full faucet replacement may be recommended.

DIY or Call a Plumber?

Simple cartridge replacements can sometimes be a DIY project, but if you're not comfortable working with plumbing or if the faucet has unusual connections, it's best to call a residential plumber in Arroyo Grande. A wrong move can turn a $50 repair into a $500 problem.

Quick Facts: Leaky Faucets

Repair time: 30–60 minutes

Common cause: Worn cartridge or O-ring

Water wasted: Up to 3,000 gallons/year

When to call a pro: If the drip persists after tightening, if you see corrosion, or if you're unsure about the faucet type

Quick Facts: Clogged Drains

Repair time: 30 min – 2 hours

Common cause: Hair, soap scum, grease, or tree roots

Warning signs: Slow drainage, gurgling sounds, bad smells

Avoid: Chemical drain cleaners — they can damage pipes

Clogged Drains — Slow Drains to Full Backups

Clogged drains are one of the most frequent calls we get from homeowners across Grover Beach, Pismo Beach, and the entire Five Cities area. A slow drain might seem like a minor annoyance, but it often signals a bigger problem forming deeper in your pipes.

What Causes Clogged Drains?

Kitchen drains typically clog from grease, food particles, and soap buildup. Bathroom drains collect hair, soap scum, and personal care product residue. Main sewer lines can be invaded by tree roots or blocked by years of accumulated buildup.

How Long Does Drain Clearing Take?

A simple drain clearing on a single fixture takes about 30 minutes to 1 hour. More complex blockages deep in the main line can take 1–2 hours and may require camera inspection to locate the obstruction. If tree roots are involved, additional work may be needed.

Why You Should Skip Chemical Drain Cleaners

Store-bought chemical drain cleaners can corrode your pipes from the inside out, especially with repeated use. They're also only effective against certain types of clogs. A professional plumber uses mechanical methods (drain snakes and hydro-jetting) that are safer for your plumbing system and more effective at removing the clog completely.

Running Toilets — A Silent Water Waster

A running toilet can waste 200 or more gallons of water per day — that's potentially thousands of dollars a year on your water bill. The good news? This is usually one of the quickest and most affordable plumbing repairs.

What Causes a Running Toilet?

The most common culprits are a worn flapper valve that no longer seals properly, a faulty fill valve, or an improperly adjusted float. In older toilets, internal components can degrade, crack, or warp over time.

How Long Does the Repair Take?

Most running toilet repairs take just 15–45 minutes. A flapper replacement is the simplest fix. If the fill valve or flush valve needs replacement, it may take closer to 45 minutes. In some cases, especially with very old toilets, we may recommend a full toilet replacement for better water efficiency and reliability.

Quick Facts: Running Toilets

Repair time: 15–45 minutes

Common cause: Worn flapper or faulty fill valve

Water wasted: 200+ gallons per day

Pro tip: Add food coloring to the tank. If color appears in the bowl without flushing, you have a leak.

Quick Facts: Toilet Flange Issues

Repair time: 1–2 hours

Signs of trouble: Rocking toilet, water at the base, sewer smell

Risk if ignored: Water damage to subfloor, mold growth

Our recommendation: If we're pulling a toilet for a flange repair and the toilet is old, it's often worth upgrading to a new, more efficient model at the same time.

Toilet Flange Repair — Stop the Rock & Roll

If your toilet rocks when you sit on it or you notice water seeping around the base, you likely have a faulty toilet flange. The flange is the fitting that connects your toilet to the drain pipe in the floor. When the bolt slots wear out or the flange cracks, the toilet can't be secured properly, causing the wax seal to break and leading to leaks.

How Long Does a Flange Repair Take?

A toilet flange repair typically takes 1–2 hours. This involves removing the toilet, replacing or repairing the flange, installing a new wax seal, resetting the toilet, and ensuring it's secure and level. If the subfloor has water damage, additional repair time may be needed.

Water Heater Problems — No Hot Water?

Waking up to a cold shower is never fun. Water heater issues are among the most urgent non-emergency plumbing calls we receive from homeowners in Arroyo Grande and Pismo Beach.

Common Water Heater Symptoms

No hot water at all: Could be a failed thermocouple, pilot light issue, or a failed heating element.

Water not hot enough: May indicate a failing heating element, sediment buildup, or a unit that's too small for your household.

Strange noises: Popping or rumbling sounds usually mean sediment has built up at the bottom of the tank.

Leaking from the tank: This often means the tank itself has corroded through. Replacement is usually the only option.

Rusty water: Could indicate a failing anode rod or corroding tank walls.

Repair vs. Replace — How to Decide

Repair if: Your water heater is under 8 years old, the issue is a component failure (thermocouple, heating element, anode rod), and the tank itself isn't leaking.

Replace if: Your water heater is over 10–12 years old, the tank is leaking, you're seeing rust in your hot water, or repair costs exceed 50% of a new unit.

Consider upgrading to tankless if: You want endless hot water, lower energy bills, and space savings. With available rebates and tax credits of up to $2,400, the upgrade can actually be more affordable than a tank replacement. Learn more about our tankless options.

How Long Do Repairs & Replacements Take?

Water heater repair: 1–3 hours depending on the issue. Component replacements like thermocouples and anode rods are on the shorter end.

Tank water heater replacement: 4–6 hours. This includes draining the old unit, disconnecting and removing it, installing the new one, and testing.

Tankless water heater installation: Typically a full day (6–8 hours). This is because tankless units often require gas line upgrades, new venting, and electrical modifications. The investment pays off in energy savings and endless hot water.

Pipe Leaks — Hidden Damage Behind Your Walls

Pipe leaks can range from a minor drip under a sink to a major burst behind a wall that's flooding your home. Either way, they need prompt attention from a qualified plumber in Arroyo Grande to prevent water damage, mold growth, and structural issues.

How Long Does a Pipe Leak Repair Take?

An accessible pipe leak (under a sink, in a crawlspace, or near the water heater) typically takes 1–2 hours to repair. Leaks hidden behind walls or in ceilings may take 2–4 hours because drywall may need to be cut to access the pipe. In some cases, especially with older homes that have galvanized or corroding copper pipes, a partial or full repipe may be the better long-term solution.

Signs You Have a Hidden Leak

Water stains on walls or ceilings, unexplained increase in your water bill, the sound of running water when nothing is on, musty smells or visible mold, and warm spots on floors (for hot water line leaks) are all signs that warrant a call to a professional.

Pipe Leak? Act Fast.

Water damage gets exponentially worse with time. A small leak behind a wall can cause thousands of dollars in damage if left unaddressed for even a few weeks.

Step 1: If actively leaking, shut off the water at the main valve.

Step 2: Call a licensed emergency plumber immediately.

Step 3: Document the damage with photos for insurance.

Quick Facts: Whole-Home Repipes

Partial repipe: 4–8 hours

Full repipe: 1–2 days

Material: Uponor PEX piping

Best for: Homes with galvanized pipes, recurring leaks, or low water pressure

Additional work: Drywall repair typically done separately

Learn about our repipe services →

Whole-Home Repipes — When Repairs Aren't Enough

If you're dealing with recurring leaks, rusty water, or persistently low water pressure, the underlying problem may be your entire pipe system. Many homes in the Five Cities area — especially those built before the 1990s — still have original galvanized steel or early copper piping that's reached the end of its lifespan.

How Long Does a Repipe Take?

A partial repipe (replacing pipes in a specific area like the ceiling or bathroom) takes about 4–8 hours, often with water restored the same day. A full whole-home repipe typically takes 1–2 days. We use Uponor PEX piping, which is flexible, durable, freeze-resistant, and comes with a 25-year warranty.

During a repipe, we cut out the old piping, route new PEX lines, and reconnect all fixtures. Drywall repair (where we cut to access pipes) is usually handled by a separate contractor or can be coordinated as part of a larger project.

Shower & Tub Valve Replacement

If your shower won't maintain temperature, leaks behind the wall, or has an outdated three-handle setup, it may be time for a valve replacement. We frequently upgrade old three-handle tub/shower valves to modern single-handle mixing valves (like the Moen remodel kits designed specifically for this purpose) — giving you better temperature control and a refreshed look.

Typical repair time: 2–4 hours. Working with older galvanized water systems can add time due to the condition of the existing pipes. Learn about our remodel plumbing services.

Garbage Disposal Repair & Replacement

A jammed or leaking garbage disposal is a common kitchen plumbing issue. Sometimes a simple reset or clearing a jam is all that's needed (your disposal has a small red reset button on the bottom — try that first!). But if the unit is leaking from the body, making unusual grinding noises, or won't turn on at all, replacement is usually the best option.

Typical repair time: 30 minutes for a simple jam clearing; 1–2 hours for a full disposal replacement including new connections.

Sewer Line Backups — A Plumbing Emergency

A sewer backup is one of the most serious plumbing emergencies a homeowner can face. When your main sewer line is blocked, sewage can back up into your home through toilets, showers, and floor drains. This is a health hazard and requires immediate attention from an emergency plumber in Arroyo Grande.

Common causes: Tree root intrusion, collapsed or broken sewer pipes, accumulated grease and debris, and foreign objects flushed down toilets.

Typical repair time: 2–6 hours depending on the cause and location of the blockage. Camera inspection may be needed to identify the exact problem. In severe cases involving collapsed pipes, excavation and line replacement may be required (this is a multi-day project).

If you're experiencing a sewer backup, call us immediately at (805) 459-1646.

Frequently Asked Plumbing Questions

Here are answers to some of the most common plumbing questions we get from homeowners in Arroyo Grande and the Central Coast.

As a general rule: if the fix involves turning off the water supply, working behind walls, or dealing with gas lines, call a professional. Simple tasks like plunging a toilet or tightening a faucet handle are usually safe for DIY. But if you're ever unsure, it's better to call and ask — a quick phone consultation can save you from a costly mistake. Call us at (805) 459-1646.

In most Arroyo Grande and Five Cities homes, the main shut-off valve is near the front of the house where the main water line enters, often in the garage or near an outside hose bib. There's also usually a shut-off at the water meter near the street. Knowing where these are before an emergency happens is one of the most important things you can do as a homeowner.

Tank water heaters typically last 8–12 years. Tankless water heaters can last 20+ years with proper maintenance. Signs it's time to replace include: age over 10 years, rust in your hot water, leaking from the tank, or insufficient hot water for your household. Regular maintenance like anode rod replacement can extend the life of your water heater. Learn about our water heater services.

Yes — the Central Coast generally has moderately hard water. Over time, mineral deposits can build up inside your pipes, water heater, and fixtures, reducing efficiency and lifespan. A water softener can help protect your plumbing system and improve water quality throughout your home. We install and service water softeners as part of our plumbing services.

In California, permits are generally required for any plumbing work that involves new pipe installation, water heater replacement, or changes to the existing plumbing system. Minor repairs (like replacing a faucet or fixing a leak) typically don't require permits. As a licensed plumbing contractor in Arroyo Grande, we handle all necessary permits and inspections as part of our service.

We use quality products from manufacturers we trust, including Moen (fixtures and the Flo smart leak detector), Uponor (PEX piping systems), Noritz (tankless water heaters), and Bradford White (tank water heaters). We choose these brands because they offer reliability, warranty support, and proven performance. See all our services.
