Sewer Lateral Repipe Repair in San Diego’s Mission Hills

A Mission Hills homeowner called us to perform a video sewer line inspection, and provide a detailed estimate on a drain and sewer issue that had been causing problems for a number of years. Different plumbers had worked on this 96 year old main house drain and sewer over the years, patching the old galvanized cast iron pipes with plastic ABS. The sewer line runs under the house and then down a steep hill, before emptying into the City of San Diego lateral that runs through the canyon in back of the many adjacent homes.  After performing a video camera pipe inspection, it was determined that there were roots growing into the sewer in multiple spots, and we were hired to remove the old pipes, replacing them with all new ABS material, performing what is referred to as a Repipe.

While examining the pipes with our video camera, we also uncovered an area at the bottom of the hill where the house’s sewer lateral empties into the city main sewer line. Previous plumbers had used concrete to cover the area over a space between the bottom of the house’s sewer line, to where it connects to the City main. After digging a deep hole to inspect and locate the connection of the home’s sewer lateral, we removed the concrete and securely attached the new ABS into the City lines.

Top 8 Plumbing Repairs in San Diego

“We’ve found that the most common reasons customers call us, fall into one of eight main categories,” according to Carini President and Founder Gabriel Carini. “A lot of homeowners can identify their plumbing issue, but not always the underlying cause of the problem. For example, uneven water pressure can be the main cause of all kinds of plumbing problems, including leaky faucets and problems keeping pressure in one room when plumbing appliances are being used simultaneously in another.”

Top 8 plumbing repairs in San Diego

1. Water Pressure Problems

Water pressure regulators can sometimes solve mysterious plumbing problems

One of the most severe and possibly expensive underlying causes for low water pressure is when old plumbing pipes  become too corroded over the years.  The scale and build-up in the pipes inhibits the free flow of water. Home water pressure regulators turn down the water pressure that comes into houses from the public water main. The water pressure is adjusted to a pressure that is usable by the homeowner and in line with normal household plumbing,  fixtures and appliances. It also aids in preventing pressure surges from coming into household plumbing from the public water main. Hard San Diego water is a recurring theme for plumbing problems, whether for water pressure problems or stoppages in pipes and water heaters.

2. Water Heaters and Tankless Water Heaters

Tankless water heaters provide hot water on demand, heating cold water directly without using a storage tank. When someone turns on the hot water at a sink or shower, cold water travels through a pipe into the unit. The water is heated by either an electric or gas burner. Tankless water heaters deliver a continuous supply of hot water. Unlike tank type water heaters, there is no need to wait for a storage tank to fill with enough hot water. Top tankless water heater brands include Noritz, Navien, Rheem and Rinnai

Water heater repairs include

  • Build up of Minerals

Faucet with hard water damage

The hard water in San Diego homes is one of the main culprits behind tank and tankless water heater repairs. The calcium and magnesium in hard water, inside a tankless water heater can cause a ton damage if not dealt with. Experts say to perform a water flush once a year to provide protection against damage.


3. Quality of Water (Whole Home Water Filtration Systems)

Whole house filtration systems connect directly to the main water line coming into your home. That ensures that all  the water dispensers in your home – kitchen and bath faucets, toilets, showers, and washing machines – provided treated water that is purified of a variety of potentially harmful chemicals and minerals. The whole house water filter connects to the main water line prior to splitting into the hot water heater

4. Drains and Sewers (Including Sewer Camera Inspections)

A stopped-up drain can be the result of a simple problem, or the first indication of a more serious issue with sewer pipes.  A sewer camera video inspection may not the the first course of action taken by your plumber, but it could the the way to save you time and money by showing the underlying causes of the problems up close and personal

What is a sewer camera video inspection? It’s a process where your plumbing company  runs a video line through your sewer pipes. The video can view all the way down your branch lines or down the house’s sewer line. A camera is at the end of the line that lets you see the line in real time.

5. Gas Line Repair

Gas fire pit or gas fireplaces may require gas line repairs in San Diego homes









The indicators that you might have a gas leak and require gas line repairs or replacement are pretty standard, no matter if you live in San Diego or Miami. Following are the most common gas line repair and installation applications:

Gas Leak Repair for Outdoor Appliances and Fixtures:

  1. Gas BBQ grills, fire pits and fireplaces, courtyard patio heaters
  2. Pool or Spa Equipment
  3. Gas Line relocation for Tankless or tank-type water heaters

Gas Line Repair for Indoor Appliances and Fixtures:

1. Boilers, Furnaces, Space Heater, clothes dryers, kitchen remodels

2. Main Gas Line from your home to the street

6. Shower, Tub and Sink Faucet Repair

Shower, tub and faucet repairs common due to hard water in San Diego


San Diego’s hard water affects faucets throughout the home, similar to how it affects hot water heaters. It’s not uncommon to see the familiar white calcium or limescale build-up on faucets. One popular solution for hard water is to combine a whole home water filtration system with an anti-scale system.

7. Toilet Repair and Replacement

Toilets come in different shapes and sizes for San Diego residential application

Depending on age, wear and quality of installation, toilets can be repaired or sometimes require replacement. Low-flow or low flush toilets use a lot less water than full-flush toilets, saving consumers on water bills and energy usage. Low-flow toilets typically use 1.3  gallons or less per flush, compared to 1.6 gallons per flush or more.

8. Re-Piping

Finally, re-piping is a plumbing application that is fairly common but one that we all hope to avoid. Pipe technologies have evolved dramatically over the years, and many older homes still have original plumbing that will need to be replaced at some point in the future.



How to Select the Right Size Tankless Water Heater for San Diego

Average water temperatures coming into San Diego homes









How to Select the Right Size Tankless Water Heater

There’s no question that tankless water heaters, also known as on-demand water heaters, are gaining in popularity with smart homeowners. A tankless water heater only heats water that is needed and does so very rapidly.

So how do you choose the right size tankless water heater for your San Diego home?

Step One

First, start by estimating the flow rate and temperature rise you’ll need for the application – a whole home vs. just a bathroom for example.

Determine the maximum number of appliances and fixtures you want to run and their total flow rate.

Then, using gallons per minute, add up their flow rates (gallons per minute). This is the desired flow rate you’ll want for the demand water heater.

Tankless Water Heater Flow Rates

How much hot water do you require at any one time? It’s probably unlikely that you will be running two showers at the same time. Maybe a shower and a couple sinks simultaneously would be more realistic. The chart below shows the range of water usage and average water temperatures for various fixtures. We suggest using 2.5 gpm for a shower and 1.0 gpm for a bathroom as a reference point in determining your total simultaneous water needs.

Tub4.0 GPM102°F
Shower2.5 – 3.0 GPM104°F
Washing Machine2.0 GPM120°F
Dishwasher1.5 GPM110°F
Kitchen Sink1.5 GPM110°F

Here are some other scenarios, where you might have guests using showers simultaneously or a vacation rental where people don’t care how much water they use. For example, if you are running 2 showers at the same time, you will need 5 gallons of hot water per minute from the tankless water heater. If you were running a shower and the washing machine at the same time, you would need 4.5 gallons per minute from the water heater. In either of these situations, you will want to size the unit that meets or exceeds how much hot water you need at the same time.

Step Two

Calculate required temperature rise. To quantify temperature rise, subtract the incoming water temperature from the desired temperature you want from the fixtures. Let’s say your average incoming water temperature is 50°F. Even though your incoming water temperature could be higher, some experts recommend using a lower temperature assumption, thereby ensuring you will not undersize your tankless unit.

For the majority of users, you’ll want your water heated to around 105–115°. On the low end of this example, you’ll need a tankless water heater that produces a temperature rise of 55°.

Here’s another scenario: Average shower temperatures will be between 104–106° and uses 2.6 gpm’s of water. If you assume your water temperature is 50° coming into your home, and you want to ensure enough hot water to run two showers at the same time, what temperature rise would be required?

Here’s the answer: The water temperature coming into your house has to be raised from 40 to 105 degrees. You’ll want to heat at least 5.2 gallons of water per minute.  With this information, spec out a tankless water heater that can produce at least a 60 degree rise in temperature at 5.2 gallons per minute.

Top electric tankless water heater installation applications

“Tankless heaters are sometimes referred to as demand type water heaters,” said Carini. “Since they provide hot water only as it is needed, home and business owners can realize large savings in their utility bills compared to conventional ‘tank’ type water heaters.”

There are a variety of scenarios where tankless water heaters help homeowners save money. Depending on the size of the home, it’s possible that multiple units might be required to handle different appliances – like washers and dryers; or if you are needing hot water at the same time in different parts of the house.

Carini explains that some of the typical residential and commercial applications for tankless water heaters include single family whole house water heating, multi-family residential, point-of-use water heating, retail, restaurants, beauty salons and offices.

Top 5 tankless water heater repairs

Some of the most common repairs on tankless water heaters include:

  • Build up of Minerals
tankless water san diego

Faucet with hard water damage

San Diego has hard water – similar to 85% of U.S homes. The two main components that cause hard water are calcium and magnesium, and their presence inside a tankless water heater can cause lots of damage if not properly addressed. A once-per-year water flush is recommended to protect against damage.


  • Too many users – an overloaded system

There are things you can do – reduce water usage, reset the unit periodically, or consider upgrading to a larger capacity unit. And don’t forget about adding recirculating pumps

  • Error messages about air supply or exhaust blockage

Your tankless hot water heater could be experiencing problems related to combustion air or improper venting

  • No Ignition Message

For some reason, the hot water heater is attempting to ignite, but it’s not happening. This kind of problem is often related to a gas supply or venting issue.

  • Error message about flame failure

This could be a problem with gas pressure; your gas line could be too small; the regulator could be failing; or it could be caused by combustion problems or venting.

Are Tankless Water Heaters the Spotify of the Appliance Industry? We Examine Five Main Similarities and Benefits

Spotify and Noritz tankless water heatersClick here to learn more tankless water heaters.

Spotify announced last month that it will begin offering political coverage and news to expand on its already dominant market share in the music streaming market.

Similarly, the market for tankless water heaters is expected to experience more growth in North America than all other global markets in the next six years.

As big fans of both of these products, we at Carini got to asking: just how similar are these two industry innovators?

1) Limitless Hot Water

Tank-based water heaters offer a finite amount of hot water. Just like Spotify’s endless streaming, tankless water heaters provide limitless hot water by heating only the water that flows through them from pipes they’re connected to. Say goodbye to cold showers because another family member used all the hot water!

2) Tankless Water Heater Installation Increases Efficiency and Reduces Costs

In a traditional tank-based water heater, the tank heats water all the time. With a tankless unit, the water is only heated when you need it, which means you save money and energy. We love being as efficient and cost effective with our water usage as we are in our music streaming and discovery!

3) Twice the Life Expectancy of Storage Water Heaters

Most tankless units last about 20 years, which is double the life expectancy for tank-based units. Tankless water heaters are already the norm in Europe and Japan – only time will tell if they make traditional heaters obsolete in the US like Spotify has done to CD sales.

4) Tankless Design Saves You Space

Traditional water heaters’ large storage tanks make them inconvenient and cumbersome to place in your home. Because tankless units don’t have tanks, they’re much smaller. They’ll save you space just like Spotify’s cloud saves you space on your hard drive!

5) Recirculation Pumps Give Instant Hot Water

We love how Spotify Discover adapts to our music taste. With new technologies like smart recirculation systems, now our water heaters can learn our preferences, too!

These systems learn your peak water usage times and begin heating the water just before you need to use it. This way, there’s no wait time for hot water.

The top manufacturers of tankless water heaters include Navien, Noritz, Rinnai, and Rheem.

Don’t Do It Yourself, San Diego! 5 Mess-Ups That Show Why You Need a Drain Cleaning Service

Many residents of America’s finest city think they can save money on drain cleaning by renting a snake or using drain cleaner instead of consulting a San Diego drain cleaning service. However, using an experienced drain cleaning company means you’ll get vital expertise to evaluate many factors and make sure your repair is properly executed.

The age, material, and length of your pipes, as well as clog type and possibility of sewer inspection camera, are all intricately interrelated and therefore best interpreted by an expert. So-called quick fix solutions like Drano and other drain cleaners are less effective and acidic and harmful to the environment.

Avoid These Scenarios By Calling a San Diego Drain Cleaning Company!

1) Sewer Snake in the Pipes

Our plumbing team helped a client who had rented a sewer snake from home depot to unclog their drain. Due to improper use, 100 feet of cable became stuck underneath asphalt. Two days of downtime were necessary to dig up the ground, remove the cable and put the pipes back together. 

2) Blown Pipe from Botched Clogged Drain Remedy

Another Carini client rented a jetting machine and used it on extremely old pipes in an attempt to remedy a persistent clog. “The client blew up a sewer line underneath concrete,”  “They didn’t know for two months that it was broken until water began seeping up from it.” Total repair cost: $8000

3) Wrong Sewer Snake

Choosing the wrong snake for a job can also lead to costly repairs. “I helped a gentlemen who had used too powerful of a snake and destroyed the drain fittings under his home,” said Ron. “We had to replace numerous damaged fittings and it was a real headache for everyone.” Total repair cost: $2000

4) Clogged Toilet Catastrophe!

Even using the right size snake can be an issue if it’s not right for particular fixture. “I can still remember the disappointment on this homeowner’s face when she saw that her husband had turned the inside of their toilet black by pushing a sewer snake down it. The porcelain was severely damaged and they had to purchase a new toilet.” Total replacement cost: $700

5) Possible Danger

“An electric drain snake can also be super dangerous if it catches your arm, hand or clothing,” he said. “The last thing I would want is a customer to hurt themselves doing something that would be quick and affordable to contact a drain cleaning company for.”


The Age of a Navien Tankless Water Heater from its Serial Number

Different tankless water heaters a consumer might have installed by San Diego plumbers, include Navien, Noritz, Rheem and Rinnai. Each have there own system of listing things like the age of the unit on the warranty data plate.
