Common Water Heater Problems We Repair in San Jose
We've seen the full spectrum of water heater repairs in the San Jose area but below we've listed the absolute 2 most common problems we encounter when going out to repair calls
No Hot Water
Water heaters losing their ability to produce hot water is one of our two most common calls we get for repair requests. Typically when looking at a water heater that isn't leaking but isn't getting hot water, we are looking at the repairable components of the water heater. There are only a few repairable components we look at for today's gas storage tank water heaters, which include the gas control valve, which is what you use to set the temperature and light the pilot, and it connects directly to the burner inside the sealed combustion assembly.
The other component we'll look at is the burner assembly, which on some models, a failed thermocouple can be replaced separetely, but with many sealed combustion water heaters, once the burner assembly needs to be removed the entire burner assembly may need to get replaced
Having no hot water doesn't immediately mean you need a full water heater replacement, when you call us out we'll diagnose exactly what's causing the unit to stop producing hot water and give you an honest answer of whether the failed component can be repair or replaced.
Leaking Water Heater
This is the other most common repair call that we get. When we evaluate leaking tanks, our first step is pinpointing exactly whether the leak is coming from the actual tank or the connected plumbing, we estimate that the leak is from the connected plumbing to the water heater about 10% of the time.
When there is a major leak, it often means the water heater tank has been compromised, which is commonly paired with the loss of hot water. San Jose's hard water accelerates the likelihood of compromised tanks due to the effects of aggressive hard water eventually rusting through the heater and developing pinhole leaks.
Other Common Problems
Some other common issues we get called for include unusual noises, inconsistent water temperature, slow heating, code issues, etc.
What to Do Right Now If Your Water Heater is Leaking
If your water heater is actively leaking, we advise you to turn off your water to avoid any further damage from the leak, you can find your shut-off valve on your cold water supply and pull it up to stop the flow of water.
The biggest mistake we see San Jose homeowners make is not knowing how to shut off the water to their water heater, mainly because of the amount of water storage tanks hold which can lead to extensive collateral damage if a major leak does occur. In order to be prepared for a sudden leak, it's important that you know where your shut-off valve is, make sure it is in working condition, and know how to operate it before an emergency.
Our plumbers have seen many cases of leaks causing a lot of damage to floors, drywall, and surrounding items that are in the vicinity of the leak.
What Makes San Jose Water So Tough on Water Heaters
We believe the #1 factor in premature water heater failure in San Jose and the surrounding Santa Clara County is the extremely hard water that residents experience in the area. Untreated hard water creates calcium and mineral deposits that significantly reduce the lifespan of plumbing appliances. For storage tank water heaters specifically, sediment buildup, tank-lining degradation, premature leaks, and inefficient performance in general are all byproducts of San Jose's hard water.
For tankless units, mineral buildup on the heat exchanger is the primary issue and can cause operational/heating issues before a leak is even present - manufacturer descaling and flushing protocols exist for the reason of preventing this. We notice that more technologically advanced units are prone to be more sensitive to mineral buildup for tankless units, and that maintenance is especially important for this kind of heater when there is no present water treatment in the home.
Heat pump water heaters which are becoming far more popular in San Jose because of the incoming 2027 gas water heater ban are affected by hard water through mineralization harming the heating elements and solenoid valves of the unit.
If you don't have any water treatment in your home such as a water softener, it's very important to always take in consideration our local hard water before making any decisions on your plumbing systems, as unit lifespans, efficiency, and maintenance are all very much affected by it.
Water Heater Problems We Repair
Is Water Heater Repair or Replacement the Right Choice
The first thing we recommend any San Jose homeowner considers before deciding between repair and replacement is the age of the water heater, then what is exactly wrong with it right now, for standard storage tanks, once you've reach over 10 years, we almost always see that a water heater replacement is more cost efficient than a repair to an aging system that still has the potential to fail again later on.
Some repairs with parts can approach about 50% of the cost of supplying and installing a new water heater. But the decision isn't always identical for every water heater. Tankless units have different warranties, lifespans, and repair considerations to weigh.
It mainly comes down to the difference between the cost of a potential repair versus the cost of replacing the unit, and evaluating which will save more in the long run. Typical manufacturer warranties run at about 6 years, so if your heater is newer it makes the case for a repair a lot stronger, but again, it is quite situational and depends on the exact age, problem, and cost comparison of both options.

Tank, Tankless, and Heat Pump Water Heater Repair
The 3 main water heaters Venture Plumbing operate on are standard gas tanks, tankless heaters, and electric/heat pump water heaters.
Standard Gas Water Heaters
These are the most common water heaters we seen in San Jose homes, and are typically the easiest of the three to repair due to the simplicity compared to tankless and electric units
Tankless Water Heaters
Tankless units are a bit less forgiving for repairs, they have more electronics, sensors, internal communication, and specialized components, which can make repairs more difficult due to the complexity, on top of the fact that they do not have stored reserves, meaning if hot water goes out, it happens immediately. In addition, tankless replacement parts often are not available off the shelf, and usually require an order in. Tankless maintenance is very important because of the local hard water and multiple different points of failure that exist
Heat Pump Water Heater
These heaters are naturally becoming more popular in the area because of their energy benefits and the incoming ban on gas water heater units. These have more technology/electrical components, solenoid valves, communication wiring, and more. Like tankless, the large amount of different components adds to the amount of points that could need service eventually. Proper maintenance for these heaters are important as well because of the technological complexity they have and the water quality the work with.
An example of a recent tankless repair we've completed, we received a call that a homeowner's tankless unit was not producing hot water but wasn't leaking. The unit was still under manufacturer warranty and when we dispatched out to the home, we found that calcium build up had affected the functionality of the solenoid valves, a direct result of hard water. We then had to diagnose with the manufacturer's technical department to determine the warranty parts that needed to be shipped to complete the repair. The homeowner was without hot water for roughly 3 days while waiting, and we returned as soon as possible once the parts arrived and we completed the repair. The alternative to this option would've been replacing the tankless unit at a substantially higher cost.
Water Heater Maintenance
Tank Maintenance
Storage tank gas water heaters should ideally be flushed at least once per year at the bare minimum, especially if you have untreated water due to San Jose's local hard water. Without maintenance your tank heater is more likely to accumulate sediment, perform less efficiently, possibly degrade the tank, and make potential leaks or even failure more likely down the road.
Tankless Maintenance
Tankless water heaters need to be descaled and flushed at least once a year to prevent mineral buildup from hard water, and as previously mentioned, with the larger amount of complexity, tankless units have more potential points of failure which makes maintenance just as important
Heat Pump Maintenance
Annual service for a heat pump is recommended because of the added components and technology that they possess, especially in the local water quality
The practical takeaway is that annual maintenance is highly recommended for all water heater options, and it especially matters if the home's incoming water isn't being treated.
We repair all three types of water heaters, and the diagnostic approach differs for each because the failure modes are fundamentally different.
What to Expect When We Arrive
Scheduling and Arrival
When you contact us for a water heater repair, our goal is to exceed expectations by not only diagnosing the problem accurately, but making sure each step of the way is a smooth and comfortable experience for the homeowner, we do this by making sure we have everything we need to know to be prepared beforehand by our office staff such as time flexibility, special requests, or any other specifics that we need to know to deliver the ultimate client experience. We aim to look at the whole system and always give the homeowner all the info they need to make the best decision for their current situation. We are often able to get out and finish work same day depending on the repair, and we have a $99 service deposit that covers our visit that always gets credited toward approved work.
Full Diagnostic
When our technician arrives, we will properly diagnose the water heater to determine the cause of the current issue and look for anything else that may need attention during the visit to ensure we are able to get a full scope of what the condition of the unit is. We'll then explain to the homeowner what was found, what needs attention, and any other findings that come up during the evaluation, and then present multiple custom relevant estimate options ranging from economy to premium solutions that vary in pricing to give the homeowner flexibility and see what levels of service each option include, no work actually begins until an option is approved
Completing Approved Work
Based on what option gets selected, our technician will perform the entire scope of work in the same day if possible. If specialty or warranty parts are required to complete the job, there can be a ordering process. Once work is completed, we verify the system is operating properly after the repair to ensure nothing comes up down the road.
End of Job
We leave letting the homeowner know exactly what happened and what work we performed on their system, including what the issue was, what we specifically did to repair it, anything else that was discovered that could need attention and anything they should plan or monitor on going forward.

FAQ
Is it worth repairing a 10+ year old water heater?
In most cases, it makes more sense to replace a 10+ year old water heater simply because the price of replacement is usually lower than the cost of a repair for a unit that is likely to fail again in the future.
Every situation is different, and it is important to get a professional opinion before making any repair vs. replacement decisions.
Why is my water heater not producing hot water?
If a water heater is not producing hot water, it could be from an active leak. If there is no leak but the unit is still failing to produce hot water, it could potentially be the gas control valve, burner assembly, or thermocouple having issues.
Having no hot water does not automatically mean a replacement is necessary, we perform repairs on these components consistently and are often able to regain hot water production at lighter cost than a full replacement.
Should I have my water heater repaired or replaced?
It mainly comes down to the price of repair and any future repairs that will happen to the existing unit vs the cost of replacement for a new unit.
Many factors are also taken into consideration such as age, history of issues, and if there is water treatment in the home.
How does San Jose's hard water damage water heaters?
San Jose's hard water damages water heaters by leaving behind calcium and mineral sediment inside of the tank. Over time, the build up of this affects the efficiency of the water heater and cause degradation of the tank lining, which increases the odds of corrosion, pinhole leaks, and a compromised tank.
Tankless heaters accumalate minerals on the heat exchanger, which causes problems with heating and operation.
Heat pump heaters develop mineral deposits which affect componenents such as heating elements and solenoid valves
Do you repair tankless and heat-pump water heaters?
Yes, Venture Plumbing repairs tankless and heat pump water heaters. Tankless and heat pumps are more technologically complex and therefore have more potential points of failure, which makes the exact repair depend on the problem at hand and whether the necessary repair parts are available.
Can a water heater leak be repaired or does it need to be replaced?
It depends on where the link is coming from, we estimate that 10% of the leak calls we dispatch to are leaks from the surrounding plumbing/connections, which may be repairable.
But if the tank has been compromised and is leaking, it often means replacement is necessary.
