What Are the Most Common Plumbing Issues in Napa?

Located in the heart of the famous Napa Valley wine region, Napa is a popular vacation site, but it is also a lovely place to live. It is warm, but not so warm as to be intolerable, and it is home to some of the most gorgeous views in California. Homes in Napa are affected by plumbing problems that are common around the country, such as clogged pipes and slow drains, but some are more common than others.

  • Low Water Pressure: Napa’s water supply is moderately hard, which means mineral deposits in your pipes can form and lower your water pressure. The hardness of your water is determined by the levels of different minerals in your water, specifically calcium, magnesium, and sodium. 
  • Flooding: There are many areas in Napa that are susceptible to flooding, both slow-rise and flash floods. Flooding can cause damage, contribute to blocked drains and clogged sewer lines, and it can also contaminate the drinking water.

Napa is also located along the San Andreas Fault, which is one of the most active faults in the world, and there are a fair number of earthquakes. Damage to pipes is very common after earthquakes, and some problems result from the poor water supply after an earthquake. Additionally, Napa, and California in general, are prone to droughts, and there are often water waste prohibitions in place.

How Does the Water In Napa Affect Your Plumbing?

Napa’s water comes from three sources and three different treatment plants; the Barker Slough in the Sacramento Delta via the North Bay Aqueduct, which is treated by the Edward I. Barwick Jamieson Canyon Water Treatment Plant, Lake Hennessey, which is treated by the Hennessey Water Treatment Plant, and Lake Milliken, which treated by the Milliken Water Treatment Plant. According to testing done by the City of Napa, the water from all three sources is moderately hard. Whether water is considered soft or hard is based on the levels of calcium, magnesium, and sodium. Hard water has higher levels of calcium and magnesium, with soft water having higher levels of sodium. Hard water can cause mineral deposits to form in your pipes, resulting in lower water pressure, and it can also deteriorate your fixtures, appliances, and plumbing equipment more quickly than soft water.

How Much Does Plumbing Usually Cost in Napa?

Plumbing repairs are often one of the more costly home repairs, particularly if repairs are not done right away. On average, plumbing costs in Napa are between $159.00 and $1,015.00. Costs for any inspections needed as well as permit fees are typically not included in these prices, nor is sales tax on materials. Some other factors will affect the cost of your plumbing repairs as well.

Cost Factor: Size and Difficulty

As problems get bigger and more difficult, they become more expensive to repair. Costs also tend to increase quickly in homes where the plumbing is in poor condition because often more problems are discovered during the project. A dripping faucet could expose problems, such as damaged pipes and mold, that are more expensive, and require more time to fix.

Cost Factor: Materials

PVC plumbing is generally the most common pipe material that our plumbers use, in large part because it is also the cheaper option for pipes. If our plumber needs to use copper, stainless steel, or ABS pipes, these will raise your costs. Sales tax for materials, which is currently 7.75%, is also a factor in how much your repairs will cost. Many installation projects, such as installing a water softener system, will use a fixed charge which typically accounts for the cost of materials.

Cost Factor: Fixed Charge or Hourly Charge

Depending on the plumbing project, it may be priced using a fixed charge or an hourly charge. Projects such as toilet installations, often use a fixed charge because the cost for time and materials are generally similar. More complicated projects, including projects where you need to hire a contractor for build back, are almost always priced using an hourly charge. An hourly charge generally only represents the cost of labor and does not include the cost of supplies and materials. A contractor is typically only needed for extensive renovations or remodels.

Can Better Plumbing Save You Money in Napa?

You bet! By being proactive about plumbing repairs or updates, you usually end up saving money over time, even if you have to spend a little more upfront. Preventing more expensive repairs down the road will not only save you money in general, but it can also help you save money on your utility bill. A dripping faucet might not seem like a major problem, but it can actually end up costing you around an extra $20 a year, as well as waste over 3,600 gallons of water a year, which is enough to fill a small above-ground pool. Plus, only 1% of water on the planet is suitable for human consumption. And it is always nice to have an extra $20 in your bank account, plus it will probably earn interest as well! Here are a few more ways that better plumbing can save you money.

  • Having more efficient fixtures not only saves money on your utility bill, but is an important measure in conserving water. Additionally, the state of California offers rebates on energy-efficient washing machines as well as water heaters. The City of Napa also has various rebates, and they also have energy programs you can participate in, as well as free water-saving devices for residents. There are some other rebates on the California Water Service website you can take advantage of.
  • It also often increases the value of your home. By promptly fixing leaks and slow drains, installing energy-efficient fixtures, as well as installing a dishwasher if your home does not already have one, you can increase the value of your home, and even decrease your property taxes using rebates.

When Should You Call the Water Utility Company in Napa Vs Hire a Plumber?

Most of the time, the majority of plumbing problems you come across can be managed by our plumbers. However, there are some instances where the utility company will need to be involved. Sometimes it is simply something where, legally, only the utility company can step in, and sometimes it is a situation where the problem is just not something our plumbers can help with. If you don’t know if you need to call us or the utility company, calling our plumbers to come and check out the problem is a good choice, and they will be able to let you know if you need to involve the utility company. 

If it appears that your house has run out of water, this might be an issue with the city water supply, which would necessitate a call to your utility company. But check with your neighbors first. If your house is the only one having problems with its water supply, it is more likely that there is something wrong with the pipes in your home, and we would be the more appropriate choice.

For water leaks, it usually depends on where the leak is coming from as to whether it is your responsibility or the responsibility of the utility company to fix it. Leaks that are on your property are your responsibility, while leaks from a broken water main are the responsibility of the utility company. If you suspect a break in your water line, and the shut-off valve does not work or you aren’t even sure where it is, our plumbers can usually help you. However, if you discover the leak is from the city water main, you will still need to contact your utility company.

Always call the utility company if you spot a leak in your neighbor’s home and they are not home. Even though it seems like the most helpful thing to do, you should not shut your neighbor’s water off yourself. You can actually get in big trouble because it is illegal for you to turn another person’s water off. The utility company will come out and investigate and turn off the water if needed. Additionally, if you think your bill needs to be adjusted, you will need to call your utility company. 

When Do You Need Permits For Plumbing Service in Napa?

Attempting to fix your plumbing without our professional plumbers to save money can be tempting. However, plumbing jobs can become complicated and overwhelming quickly, and often you will still need to hire us. Additionally, often you need to get a permit from the city. In most cases, if it involves an existing appliance or parts that are already in place, as long as you are not replacing or removing valves or pipes, you do not need a permit. If you are replacing something like a toilet seat that does not require water to operate, you do not need a permit. Here are some situations where the City of Napa does require a permit.

  • If you are installing or modifying the plumbing or piping system, including replacing a metallic (copper or galvanized steel) plumbing system with a non-metallic (plastic or CVPC) plumbing system. Additionally, you will need an electrical permit as well if you need to install a new grounding electrode.
  • If you are installing, repairing, or removing a well or a water softener system
  • If you are adding or changing any fixtures or drains, or you need to cap pipes from fixtures that have already been removed
  • If you are adding or remodeling a residential swimming pool or spa, excluding some prefabricated swimming pools that are installed entirely above ground.
  • If you are installing lawn sprinkler systems or backflow prevention assemblies for lawn sprinkler systems 
  • If it involves sewer lines, sump pumps, or septic systems. A septic system cleaning does not typically require a permit, but it should always be done by a licensed professional.

It is probably best to call us if your job requires a permit from the city. Our plumbers know exactly which permits are needed and will know how to obtain them from the city if needed.
