We've had a great experience with Precision Plumbing. Most recently, they helped us locate and repair three separate leaks under our concrete slab. They started with a free inspection and did a very thorough job diagnosing the issue, clearly explaining what was going on and what our options were. Their approach was professional, direct, and honest, no upselling, just practical solutions and clear communication. The work was handled quickly and efficiently. I felt confident in their expertise the entire time. We had also used them previously for a midnight plumbing emergency, and they were incredibly responsive and reliable, one of the only companies willing to come out at that time which is why we trusted them again for this most recent project. Martin & his team are super knowledgeable, dependable, a great value for what they provide and easy to work with. I highly recommend Precision Plumbing!!!

Our main water line sprung a leak and it was such a inconvenience when you don't have proper running water. After finding Precision on Google, I decided to give him a call. He was very responsive and was the first out of 3 plumbers to arrive next day in the AM. He was very easy to talk to and didn't try to up sell like the other ones. His quote was fair and I didn't feel like I was getting ripped off. I would call them back if I need any plumbing services in a heart beat!

Our main sewer line had been giving us issues for over a year. Slow drains, weird smells in the backyard, and finally a backup in the guest bathroom that pushed us over the edge. Got three quotes for a sewer replacement for our home in Laguna and these guys came in not the cheapest but definitely the most thorough. The tech ran a camera down the line first and walked me through exactly what we were looking at on his tablet. Turned out we had old clay pipe with two big root intrusions and a partial collapse near the cleanout. They scheduled the work for the following week and got it done in two days. Crew was respectful, kept the yard damage to a minimum, and even reseeded the section of grass they had to dig up. Haven't had a single issue since and I sleep better knowing it's handled.

I’m usually very nervous to call any sort of service company. I feel like they always make me feel stupid and rip me off. My toilet was clogged and I was already embarrassed to contact anyone. When I contacted Martin, he was immediately kind and explained what he would be doing. He did the job perfectly and even left my bathroom cleaner than it was before!

Really happy with the service from Precision Plumbing. I called them out for a plumbing issue at my home and they showed up quickly, which I really appreciated. The plumber was easy to talk to, explained what was going on in and got everything fixed without any hassle, no confusion, just straight to the point and got the job done right. Overall, solid experience. I’d definitely use them again if I run into any plumbing problems.

Was bracing for a hard sell when our 14 year old water heater started leaking. Two other plumbers basically tried to push tankless on me before they even looked at the unit. Called Precision in Mission Viejo and he came out the next morning, walked through both options, laid out the real cost difference and the gas line work tankless would need. No pressure either way. We went with a 50 gallon tank because the math made sense for our family. He pulled the permit, did the install the next day, hauled the old one out, and strapped the new one properly for earthquake code. Straightforward company.

Slow drains in pretty much every sink and tub at the same time, which I now know is not a good sign. Called Precision on a Monday morning and they came to the house by 1pm. He camera scoped the line first, showed me a wall of grease and gunk about thirty feet out, and explained why snaking it would only buy me a few months. They hydrojeted the whole line for a fair price. Drains have been running smoothly. Saved as #1 Plumber lol.

Both units in my duplex were backing up and I knew it was time to get the main line looked at. A friend in Laguna had used Martin before and said to call him. He came out, scoped the line first so we could actually see what was going on in there, and then hydrojetted the whole thing. years of buildup just gone.

These things always seem to happen on the weekend - the outlet from my water heater started leaking. I did a Google search to find a plumber that was open and found Precision Plumbing in Mission Viejo. Within an hour of my call, Martin was at my door. He diagnosed the problem and gave me some options. I chose getting a new water heater and fixing associated fittings. Martin was back out Monday morning to do the work. They were prompt, professional and friendly. They knew I had a tight schedule and they finished earlier than expected. They double checked to make sure everything was working, including replacing the pressure regulator to the house, which probably saved me from an even bigger future repair bill. I highly recommend Precision, for your local plumbing needs. Great service and fair pricing.

Martin helped us in the past with a clogged drain and this time with a slab leak. Again, I can't say enough good things about his team. From the start, it was clear they really know their stuff and are incredibly transparent and honest. They were thorough with the inspection and took the time to explain everything in detail. The crew that came to do the repipe was just as impressive. They were hardworking, knowledgeable, and cleaned up after themselves. It was very obvious they knew exactly what they were doing and were great at it!

Water Heater Repair Installation in Orange County

Emergency Water Heater Repair in Orange County

A failing water heater disrupts the whole household. Showers turn cold, dishes pile up, and laundry has to wait. Water pooling around the base of the tank can soak floors, walls, and stored items in the garage. A pilot that keeps going out or water that never gets hot enough are also signs that something is wrong.

Precision Plumbing repairs gas and electric water heaters, including both tank and tankless units. Our water heater leak repair service finds out whether the leak comes from a valve, a fitting, or the tank itself. We come prepared with common parts like thermocouples, gas valves, heating elements, and relief valves to fix many problems in one visit. If the unit is failing, we explain your options right away so you can decide with confidence.

Water Heater Replacement in Orange County

Tankless Water Heater Installation Service in Orange County

Many households run out of hot water when several people shower back to back. A standard tank also takes up valuable garage or closet space and keeps heating water even when no one is home. Switching to tankless is appealing, but the upgrade involves more than swapping one unit for another. Gas line size, venting, and electrical needs all affect how well the new system performs.

Our team sizes each tankless unit to your home’s peak hot water demand, so performance holds up when it matters. We check whether your existing gas supply can handle the higher load and arrange a gas line installation upgrade when needed. Proper venting and a dedicated electrical connection are set up as part of the job. You get on demand hot water, more open space, and less wasted energy.

Your Trusted Partner for Residential & Commercial Plumbing

Our Full Range of Plumbing Services

Water heaters are one slice of the work. A hot-water problem sometimes appears alongside a leak, clog, fixture issue, or another plumbing concern. Here is the rest of what we handle.
Larger jobs need somebody planning the whole sequence, not just the visible repair.
Shutting water off quickly limits the damage, so knowing where your main valve sits helps when a line fails.
Slow sinks and gurgling tubs mean the line has restricted flow, not simply a plug sitting at the strainer.
Cable machines open a path through a blockage while some buildup remains on the pipe wall.
Roots can enter sewer joints, while older or damaged pipe sections can crack or separate over time.
A warm patch underfoot, a spinning meter with every tap closed, and an unexplained jump in water use can all point toward a leak beneath the concrete.
Pinhole leaks can appear in aging copper, often inside a wall or ceiling. A single stain on drywall does not always show how far the pipe problem extends.

Scale on glassware, changes in taste, and residue around fixtures can relate to what is present in the water.

Tank and tankless units alike get repaired, serviced, and installed through Precision Plumbing.
A toilet running all night wastes water and usually points to a component that needs attention.
Dripping faucets and stiff handles wear on you every day, while mineral buildup can affect cartridges and other internal parts.

Gas work leaves no room for guessing. New runs for ranges, dryers, fire pits, and outdoor kitchens each need correct sizing, secure connections.

How A Water Heater Visit Works

Three steps cover the job from first call to finish.
Look At The Unit

Nothing gets priced over the phone without seeing the actual situation. Your heater gets inspected, tested, and compared against everything connected to it. Age, scale, pressure, connections, and venting all shape what comes next.

Hear Both Options

Repair and replacement each get explained in plain terms with the reasoning attached. Cost, remaining service life, condition, and potential future issues all factor into the discussion. The decision stays yours.

Finish It Properly

Parts go in, or the new unit does, with the appropriate connections and installation details addressed. Temperature, operation, connections, and relevant venting get checked before we pack up.

Tank Water Heater Installation in Orange County

Gas Water Heater Installation in Orange County

A traditional tank is still the right choice for many homes. It costs less upfront and works well when sized correctly for the household. The problem is that many tanks are installed with the wrong capacity, poor venting, or missing safety parts. These mistakes lead to short hot water supply, wasted gas, and real safety risks. When a new gas heater needs a larger or relocated supply pipe, we handle it through our gas line repair service.

With more than 26 years of experience, our technicians know how to match the right tank to each home. A 50 gallon water heater replacement is common for families of three to five, while smaller households may do well with 40 gallons. We connect the gas supply safely, set up proper venting, and add an expansion tank where code requires one. Every unit is tested for leaks and correct burner operation before we leave.

When a heater swap turns into a larger job, the work is handled by our Plumbing Contractor side.

Tankless Water Heater Installation in Orange County

Same Day Water Heater Replacement in Orange County

When a tank starts leaking from the body, repair is no longer an option. Corrosion has broken through the steel, and the leak will only get worse. Waiting several days for a new unit means cold water and a growing risk of water damage. For most families, a fast swap is the only practical choice.

We keep popular tank sizes on hand, so your water heater installation can often happen the same day you call. Our team drains and removes the old unit, sets the new one in place, and connects it to code. We also replace worn supply lines and shutoff valves so the new heater starts on a solid footing. Hot water is usually back within a few hours of our arrival.

Electric Water Heater Repair in Orange County

Water Heater Flush Service in Orange County

Hard water leaves minerals behind every time the tank heats. That sediment settles at the bottom, where it forms a barrier between the burner and the water. The heater has to work harder, uses more energy, and wears out sooner. Rumbling or popping noises from the tank are a common sign of heavy buildup.

Our water heater maintenance visit drains the tank and clears out the sediment that has settled inside. We inspect the anode rod, test the temperature and pressure relief valve, and check the burner or heating elements. For tankless units, we descale the heat exchanger to keep water flowing at full temperature. If buildup keeps returning quickly, a hard water treatment system can reduce minerals before they reach the heater.

Gas Water Heater Repair in Orange County

Gas Water Heater Repair in Orange County

A pilot that will not hold, a burner showing unusual flame behavior, or a failed thermocouple can each point to a different problem. The gas valve, burner assembly, thermostat, thermocouple, venting, and other components may need to be checked before the right repair becomes clear. If your gas water heater keeps losing its pilot, contact us and we will find the cause before any parts are replaced.
Gas-related repairs receive careful attention because the system has to operate properly after the work is complete. Our team inspects the relevant connections and venting, complete the approved repair, and test the heater afterward. If you smell gas near the heater, treat it as a safety issue. Leave the area, avoid creating a spark, and contact the gas utility from a safe location. New runs for ranges, dryers and outdoor kitchens fall under gas line services rather than heater work.

Water Heater Questions People Ask

How long does a water heater last?

Most tank water heaters last 8 to 12 years, while tankless units often last up to 20 years with regular care. Hard water, high water pressure, and skipped maintenance can shorten either lifespan. Checking the manufacture date on the unit’s label helps you plan a replacement before it fails.

Repair usually makes sense for a newer unit with one failed part, such as a thermostat, heating element, or gas valve. Replacement is the better choice when the unit is over 10 years old and needs a costly repair. Rising energy bills and frequent breakdowns also point toward a new heater.

This smell usually comes from bacteria in the tank reacting with the magnesium anode rod, which produces hydrogen sulfide gas. Flushing the tank and switching to an aluminum zinc or powered anode rod often solves the problem. If the smell is in both hot and cold water, the issue may be the water supply instead.

Yes. California law requires water heaters to be braced, anchored, or strapped to resist movement during an earthquake. Most installations use two straps, one in the upper third and one in the lower third of the tank, and the permit inspector checks them during the final review.

A tank that is too small for the household is the most common cause. Sediment buildup, a broken dip tube, or a failed lower heating element in electric units can also cut your hot water supply short. A plumber can test the unit to find the exact cause.

Cities We Cover Across Orange County

Mission Viejo is home base, with the shop on Dolorosa and service extending roughly 20 miles from that location. That puts several South County communities within our regular service area. Water heater work, drain trouble, leaks, and other plumbing needs all get covered across the same footprint. Familiarity with the area matters because properties differ from one city to another. Older plumbing, newer equipment, attached housing, rentals, and small commercial spaces can each present different access and installation considerations. Our local experience gives us a useful starting point without assuming every property has the same setup. The rest of what we handle across the county is listed on precisionplumbingoc.com.
