Comet Plumbing And Sewer
Comet plumbing did a excellent job at my home . A fair price, competent, knowledgeable, efficient , clean and professional! Thank you Andy, I will be calling you for future issues if needed.
We had a drain issue right around the holidays and Andrew fixed it that same day. He and his team have always done great work at a fair price!
Andrew from Comet Plumbing was wonderful! He helped install two clean-outs and fixed a root infested pipe for a reasonable price (plus nice discount). I'll definitely be using them again!
Consider Better Water Heaters if...
- ✓ You need tankless water heater expertise, particularly for Rinnai systems or complex diagnostics that other plumbers have failed to resolve
- ✓ Your project is clearly defined as water heater-only work without concerns about related plumbing infrastructure
- ✓ You value a specialist who focuses exclusively on water heater installation, repair, and maintenance rather than juggling diverse plumbing projects
- ✓ You want established expertise in annual tankless maintenance programs for long-term system care
Consider Comet Plumbing And Sewer if...
- ✓ Your water heater replacement might reveal related issues like corroded pipes, inadequate gas lines, or drainage problems requiring immediate broader plumbing work
- ✓ You prefer a veteran contractor with 15 years of licensing history and exposure to complex residential plumbing scenarios
- ✓ Your property has older plumbing infrastructure where a water heater project could uncover hidden problems best handled by a full-service plumber
- ✓ You want a single contractor who can handle everything from the water heater itself to sewer lines, re-pipes, and emergency plumbing repairs
Questions to Ask Before Hiring
- → If choosing Better Water Heaters, ask whether they can handle related plumbing work if the water heater replacement reveals corroded supply lines or inadequate venting
- → If choosing Comet Plumbing, ask about their specific experience with tankless water heater installations and whether they handle annual tankless maintenance programs
- → For either company, confirm current availability and typical timeline from quote to installation given their emergency response capabilities
- → Ask both contractors what percentage of their recent projects involved water heater work specifically to gauge current practice focus
The Bottom Line
For straightforward water heater replacements or tankless system issues requiring specialized expertise, Better Water Heaters' focused specialization serves most homeowners well despite fewer years in business. However, if your home is older with aging plumbing infrastructure, if you're unsure whether related systems need attention, or if you simply want the security of a veteran contractor with 15 years of licensing and full-service capabilities, Comet Plumbing's broader experience justifies choosing them even for water heater work. The specialist wins on focused expertise; the veteran wins on scope and depth of experience.

Frequently Asked Questions
It matters most if complications arise. Comet's 15 years means more exposure to scenarios where water heater projects reveal bigger issues—corroded gas lines, inadequate venting, pressure problems—requiring immediate diagnosis and solutions. For straightforward replacements on newer homes, Better Water Heaters' 6 years and focused specialization provides sufficient experience, with the advantage of exclusive water heater focus rather than divided attention across all plumbing trades.
Better Water Heaters' specialization gives them an edge in tankless diagnostics, Rinnai servicing, and resolving issues other plumbers couldn't fix. Customers specifically mention their ability to troubleshoot complex tankless problems. However, if your home's plumbing infrastructure is older or you're uncertain about gas line capacity and venting adequacy, Comet's broader experience helps address the entire system, not just the unit itself.
Comet handles water heater replacements as part of their full-service plumbing work, and customers report satisfaction with these projects. However, their reviews don't emphasize the deep tankless expertise or specialized troubleshooting that Better Water Heaters demonstrates. For standard tank replacements, Comet's veteran experience is more than adequate; for complex tankless diagnostics or annual maintenance programs, Better Water Heaters' specialization may provide more focused expertise.
Both companies demonstrate strong emergency availability, including weekends. The difference lies in what happens after they arrive. Better Water Heaters can immediately address any water heater emergency but would need to refer out non-water-heater plumbing problems. Comet can handle whatever plumbing emergency they encounter on-site, from the water heater itself to supply line failures, sewer backups, or related issues discovered during diagnosis.

How We Compare Contractors
License Verification
All license data is sourced from official California CSLB records and verified regularly.
Review Analysis
Customer reviews are aggregated from Google and analyzed to identify patterns in service quality.
Detailed Comparison
We analyze credentials, insurance, experience, and feedback to highlight meaningful differences.
Not all licensed contractors are created equal. While a valid license is the baseline requirement in California, contractors can vary significantly in experience, insurance coverage, and customer satisfaction.
- Experience matters: A contractor with 15+ years of experience has likely encountered and solved problems that newer contractors haven't faced yet.
- Workers' compensation protects you: If a contractor without workers' comp insurance has an employee injured on your property, you could be held liable.
- Reviews reveal patterns: Individual reviews can be misleading, but patterns across many reviews often reveal a contractor's true strengths and weaknesses.
- Bond amounts vary: A contractor's bond provides financial protection if they fail to complete work as agreed. Higher bonds offer more protection.
Taking time to compare contractors on these factors can save you from costly mistakes and help ensure your project is completed by a qualified professional.
