Common Plumbing Problems in Manteca

While plumbing systems are generally the same all over, each area has their own unique set of plumbing problems as well. This is usually due to building standards, the age of homes, and what kind of plumbing equipment is, or was, popular there.

Bad PEX piping – Many new construction homes from the 2000s and 2010s used sub-par PEX piping for all of their plumbing piping. That’s why it’s not uncommon to find that rats or other pests have eaten into your water lines, causing leaks, water pressure drops, and issues with fixtures and appliances. The solution is usually a full home repipe.

Sewer line problems – New construction homes also have issues with sewer lines, either due to improper grading, bad connections, or poor material choices. Therefore, sewer laterals in Manteca tend to clog, crack, and back up a little more than they do in other locations. Older homes can also have different problems with their sewer lines, often due to older standards and materials like Orangeburg. If your home is facing sewer problems, starting with a sewer camera inspection is a good place to start.

Water Heater problems – last but not least, many new construction home builders install low-quality water heaters to save money. Since most new and first time homeowners don’t know what to look for in a water heater, it doesn’t seem like a problem until a couple of years down the line when they start breaking down on a regular basis. The solution here is to replace it with a high-quality water heater from a trusted brand like Bradford White or Navien.

If you’re considering buying a new (or not so new) home in Manteca, one of the smartest decisions you can make is to call out a plumber to perform an inspection. They can help you determine if there are any latent issues with your plumbing system, and can even help you negotiate for a lower sales price. Contact us today to schedule yours.

Read Our Reviews

“We recently purchased a house in Manteca. After a few months of moving in, we found out there are a few plumbing issues in the house. We’ve had different plumbing companies work on different issues. We try not to use one company until we are fully satisfied with their work. For each visit, we would ask for quotes on the other plumbing issues. One specific problem we had was a leaking faucet in our master bathroom. Most of the companies that gave us quotes informed us that we need new faucet because the one we have are really old. (Basically a quick fix solution). We put that on hold because it will cost a lot to buy new faucets and the labor will be costly as well.

After seeing great reviews for Simpson Plumbing, we decided to give it a try. We sent them a picture of the leaky faucet, got a quote over the phone, they came the next day to FIX it…. yup, fix not replace. They just saved us big bucks. Thanks Alex & Chris”

Sewer Inspection and Repair

With the options we provide, sewer inspections and repairs are made to be affordable as well as noninvasive when it comes to diagnosing bigger problems with your particular system. Our team is equipped with the knowledge and materials needed to fix the problem at hand, whether it be drain leaks, sewer clogs or any other problem related.

To get a sense of if you need a sewer inspection, here are some of the following issues that lead up to it:

Examining a sewer blockage with a video inspection camera

  • Trees growing into your sewer line
  • Bad odors from your plumbing or from outside your home
  • Water backing up, often into your bathtub or utility sink
  • Overflowing toilet, especially if frequent
  • Unexplained puddles of water in your lawn
  • Sunken patches in your lawn, especially if around the sewer line
  • Many more.

Issues may also come up from different factors as well, such as:

  • The city has done work on sewer lines near you
  • You have large trees near your sewer line
  • Your home is over 20 years old and the sewer has not been updated
  • You know you have an older type of sewer pipe

Sewer Repair Services

If your sewer is in need of repairs, our preferred approach is to perform trenchless sewer repair. This works much like minimally-invasive surgery: we create a small opening at one end, feed the equipment in, and repair your sewer lateral from the inside. This can fix most sewer issues without the need for tearing up your landscaping.

On shorter sewer runs, or in situations where a trenchless option isn’t available, we can also offer fully trenched sewer repair. Our team works overtime to refill all trenches to their former state once the job is done, so you won’t be stuck with an eyesore.

In some cases, you might also not require a full sewer repair. If you have a blockage that can be cleared with sewer cleaning or sewer jetting, that’s always our first choice. But that option only makes sense if your sewer line is free of cracks and not suffering from collapse.

Gas Line Repair

A broken gas line is a big problem–and an even bigger safety hazard. A ruptured gas line can contribute to carbon monoxide poisoning, which can cause serious health issues including asphyxiation and flu-like symptoms.

The good news is that they won’t be a problem for long. Our team is fully equipped for multiple kinds of gas leak detection, spot repair, and large scale replacement. We can even offer flameless soldering for gas line applications, which is significantly safer for your equipment and property.

Gas Line Installation and Replacement

For new installations, we only use the highest quality copper piping available, so you’ll be able to rest easy. Whether you’re switching your cooking range from electric to gas, you’re installing a new barbecue, or you’re getting a new natural gas clothes drier, we’ll make sure that your gas line system is ready for consistent, reliable, and long-term use. Our team is fully equipped to work with all types of gas lines, including CGP, poly fusion, and corrugated stainless steel gas lines.

Commercial Gas Line Service

Commercial natural gas applications often require more care, planning, and conscious design than a residential application. In Manteca, we have serviced gas lines for restaurants, retail stores, medical centers, and businesses of all sizes, and we’re always happy to provide references.

Water Heater Repair in Manteca

Water heater repair and replacement specialists

When it comes to finding a licensed plumber to handle your water heater repair or installation, Simpson Plumbing is the company to turn to! We do a complete inspection of the condition of your water heater to determine whether it can be repaired or if it needs to be replaced. If you don’t stop heating water in a water heater that needs to be replaced, it will eventually spring a leak and flood the surrounding area, costing you hundreds more in emergency repairs than you would’ve paid to have it replaced.

Common Signs that You May Need Water Heater Replacement

  • Puddles forming around or underneath your water heater
  • Shower and sinks not heating up immediately
  • Rusty or discolored water
  • Low water pressure
  • Higher than normal water bills

Installing Bradford White Tanked Water Heaters

For traditional, tanked water heaters, our go-to brand is Bradford White. Bradford White water heaters offer superior lifespans, high efficiency ratings, generous warranties, and trouble-free equipment. Bradford White traditional water heaters are available in electric and natural gas models, and the models we install are Energy Star qualified.

For some applications, we may also install equipment by other trusted brands, such as AO Smith and American Standard.

Installing Navien Tankless Water Heaters

Tankless water heaters often last longer, operate more efficiently, and take up less space than traditional tanked heaters–but only if they’re correctly installed and maintained. Our team installs only the best tankless water heaters by Navien, one of the most trusted names in the industry. We are also proud to be a Navien Service Specialist, which means our technicians have received thorough hands-on training with Navien product specialists and that we carry a full Navien parts kit, allowing us to fix the majority of Navien tankless water heater issues without ordering (and waiting for) additional equipment.

Navien tankless water heaters offer some significant benefits over traditional, tanked heaters. They produce a never-ending supply of hot water for long showers, filling up oversized bath tubs, or whatever you need. They last significantly longer than tanked water heaters, with limited warranties up to 15 years and equipment that can last up to 20. They also use a lot less gas or electricity to operate, though they do require higher throughput in shorter intervals.

In the end, you get a higher efficiency, more reliable, and more useful water heater.

But tankless water heaters aren’t perfect. They also require special training to service and repair, and have higher upfront installation and equipment costs. For many, the trade off is more than worth it, but speak with a specialist at Simpson Plumbing today to learn more about whether or not installing a tankless water heater is the right choice for you.

Repairing All Water Heaters

We might be picky about the kind of water heaters we install, but we’re much more flexible when it comes to repairs. Our team can diagnose and repair virtually any name brand of water heater you’ll find in North America, including American Standard, AO Smith, Slate, RUUD, Rinnai, Rheem, Kenmore, Noritz and much more. We service gas, electric, and tankless water heaters, in addition to commercial-grade heaters.

Slab Leak Detection & Repair

Pipe leaks are one of the most common problems in plumbing, but it can be hard to spot the signs when they’re under your concrete slab. Some common signs of a slab leak are:

  • Warped wood flooring
  • Wet carpeting
  • Hot spots on your floor
  • Bad, moldy smells around your foundation
  • Low water pressure throughout your home

Slab leaks, also known as foundation or concrete leaks, can severely damage your home, your plumbing, and your resale value.

If you suspect that your home has a slab leak, calling our leak detection team is a great place to start. Our team can help diagnose the issues, see if there are other problems that could be contributing or exacerbating them, and plan for the most minimally-invasive repairs possible under your unique circumstances.

Our Slab Leak Detection Options

There are many ways we detect slab leaks, including:

  • Static pressure testing
  • Video inspections
  • Line tracing
  • Thermal scanners
  • Listening equipment
  • And more

The location of the suspected slab leak is usually the biggest factor in determining how we approach detection.

How We Approach Slab Leak Repair

Fortunately, there are a few options for slab leak repair

  • Trenchless relining. If the pipe is only minimally damaged, then we can typically use epoxy pipe liners or CIPP to patch the issue.
  • Re-routing. Instead of tearing up the slab, we can sometimes re-route your pipe to pass through another part of your property. This is typically a good option if only a small number of pipes are affected, or excavating the slab would be a big issue.
  • Excavating. If there are multiple broken lines and little room for re-routing, sometimes it makes the most sense to break the slab, fix the lines, and then repair (or repour) the slab. 

Speed makes all the difference

Quickly diagnosing and solving your slab leak does more than prevent damage to your concrete slab. It can also save you hundreds, if not thousands of gallons of water, in addition to preventing mold growth in some of the hardest-to-reach parts of your home. So if you think your home may be facing a foundation leak, don’t delay!

Shower repairs are like unexpected rain on your parade—annoying but manageable. Leaky faucets are the rockstars of common shower issues. Usually, a quick fix involves replacing a worn-out washer or tightening a loose connection. If your showerhead resembles a waterfall more than a spritz, chances are it’s clogged with mineral deposits. Soak it in vinegar for a DIY spa day. Dodgy grout and caulk are the silent troublemakers, inviting water damage. Refresh them to keep your shower watertight. And let’s not forget the temperamental temperature dance—a faulty mixer valve might be stealing the show.
