Frequently Asked Questions

After the installation of your new shower or tub, adhering to a regular maintenance routine is crucial to ensure its longevity and optimal performance.

Here are some maintenance tips we recommend at Mainstream:

  1. Regular Cleaning: Use non-abrasive cleaners to clean your shower or tub. Harsh chemicals should be avoided to preserve the finish and integrity of the surface.
  2. Drain Maintenance: To prevent clogs, use drain strainers. They help catch debris and hair that could otherwise block your plumbing.
  3. Leak Prevention: Consider installing leak detectors to monitor for water leaks. Address any detected leaks promptly to prevent water damage.
  4. Mold and Mildew Control: Maintain proper ventilation in your bathroom, especially after showers or baths, to reduce humidity levels. This helps prevent mold and mildew growth. Ensure the caulk around the base of your tub remains intact and sealed.
  5. Fixture Inspection: Regularly inspect your fixtures for any signs of wear or damage and repair them as necessary to avoid leaks and other issues.

For those who may not be confident in handling maintenance tasks or simply prefer a professional touch, Mainstream offers our Service Protection Plan, a comprehensive home maintenance plan for homes in and around Spokane, WA.

The duration needed to install a bathtub or shower varies, largely depending on the specific details of the installation, such as the type of unit, the project’s complexity, and any extra features or custom work required.

However, more complex installations, such as those involving high-end models with additional functionalities or requiring significant modifications to your bathroom’s existing plumbing, may extend this timeframe.

Generally, repairing a cracked toilet bowl or tank is not advisable. A crack can significantly compromise the structural integrity of the toilet, leading to potential leaks, water damage, and hygiene issues. Upon noticing a crack, it’s critical to address the problem swiftly.

Mainstream Electric, Heating, Cooling, and Plumbing advises against attempting to repair cracks in toilet bowls or tanks due to the risks involved. Instead, we recommend replacement to ensure the safety, functionality, and hygiene of your bathroom. Our experienced team specializes in efficient and professional toilet replacements, providing a swift solution to such issues. Contact Mainstream for reliable advice and service, ensuring your bathroom remains in optimal condition.

Signs of a damaged toilet flange include a wobbly toilet, leaks at the base, unpleasant odors, or difficulty flushing, all of which suggest your toilet’s stability and functionality might be compromised. If you encounter any of these issues, the toilet flange may need attention. To address a damaged flange, the toilet must first be detached to access and evaluate the flange underneath.

While repair kits for damaged toilet flanges are available at home improvement stores, providing a do-it-yourself solution to stabilize your toilet, the repair process might seem daunting for those less experienced with plumbing tasks.

Mainstream offers expert services to tackle toilet flange problems and more. Our skilled plumbers bring years of experience to every job, ensuring a thorough and efficient repair. If the thought of plumbing repairs is overwhelming, let Mainstream handle the complexities, providing peace of mind and restoring your bathroom to perfect working order. Contact Mainstream for dependable plumbing solutions and professional repairs, safeguarding your home’s comfort and functionality.

Toilets can leak due to a variety of reasons, often leading to wasted water and increased utility bills. Common causes of toilet leaks include:

  1. Worn-Out Wax Rings: The wax ring seals the toilet base to the drain. Over time, it can degrade and lose its seal, causing leaks at the base of the toilet.
  2. Loose or Faulty Bolts: The bolts securing the toilet to the floor can become loose or corroded, allowing water to escape.
  3. Cracked Tanks and Bowls: Cracks in the toilet’s tank or bowl can lead to significant leaks. These cracks may be small and not immediately noticeable.
  4. Broken Gaskets or Flanges: Gaskets and flanges that have deteriorated can result in leaks between the toilet and the plumbing system.
  5. Condensation: In areas with high humidity, condensation on the tank’s exterior can sometimes be mistaken for a leak.

Persistent leaks not only waste water but can also cause damage to your bathroom flooring and increase your water bill.

Mainstream is equipped to swiftly identify and fix the source of your toilet leak, preventing further damage and restoring efficiency to your bathroom. If you notice a leak or a spike in your water bill, don’t hesitate to contact Mainstream. Our team of professionals will ensure your plumbing is in top condition, safeguarding your home from potential water damage.

Installing or replacing a toilet can indeed be within the reach of a dedicated DIY enthusiast. With the right tools, instructions, and a bit of patience, many homeowners can complete this project successfully.

The cost of replacing a bathroom sink can vary widely based on several factors, including the type of sink you choose, the materials it’s made from, and the complexity of the installation process. More straightforward options, such as basic drop-in or wall-mounted sinks, tend to be on the more affordable end, with prices ranging between $200 to $600 or more. Opting for vessel sinks, under-mount sinks, or sinks made from custom materials can increase the cost. Also, additional expenses might arise from the need to replace faucets, make plumbing adjustments, or cover the cost of labor for the installation.

To ensure you receive the most accurate estimate tailored to your specific needs, Mainstream is here to help. Contact us to schedule a visit, and we’ll provide you with a free, no-obligation estimate. Our commitment is to get the job done right, offering reliable and quality service every time.

There are several warning signs indicating a potential sewer line issue in your bathroom that should prompt you to act swiftly to prevent further damage. Recognizing these signs early can save you from significant inconvenience and costly repairs:

  1. Foul Odors: Persistent unpleasant smells, particularly those resembling sewer odors, are a clear indicator of a sewer line problem.
  2. Slow Draining Fixtures: If multiple fixtures in your bathroom are draining slowly, this could signal a blockage or issue within your sewer line.
  3. Gurgling Noises: Unusual gurgling sounds when flushing the toilet or running water can indicate a disturbance in your sewer system.
  4. Water Backing Up: Water backing up into sinks, showers, or bathtubs is a direct sign of a sewer line blockage.
  5. Multiple Clogs: Experiencing frequent and persistent clogs across various fixtures suggests a deeper issue within the sewer line.
  6. Wet Spots in the Yard: Noticeable wet or soggy spots in your yard near the sewer line could mean a leak or break in the sewer pipe.
  7. Foundation Cracks: The appearance of cracks in your home’s walls or floor might be caused by sewer line damage affecting the foundation.
  8. Sewage Smells Outside: Detecting unpleasant sewage odors near sewer cleanouts or in your yard is a strong indicator of a sewer line breach.

If you notice any of these signs, it’s crucial to contact Mainstream immediately. Our team is equipped to detect and resolve sewer line issues promptly and efficiently, minimizing damage to your property and mitigating potential health risks.
