Family-owned and operated since 1987, D & L Plumbing serves Central Ohio with licensed, bonded, and insured plumbing services. Below you’ll find answers to common questions about backflow testing, drain cleaning services, water heater installation and repair, boiler and radiant heat repair, sump pump installation, and more.

  • What is backflow testing, and why is it required?

    Backflow testing verifies that your backflow prevention device is working correctly to keep contaminated water from flowing into the public water supply. Many municipalities in Central Ohio require annual testing by certified backflow testers to comply with local codes and protect public health.

  • Do you install and repair backflow prevention devices?

    Yes. We provide backflow installation, repair, replacement, and testing for residential and commercial properties. If your device fails a test, we can repair or replace it and retest to ensure compliance.

  • What signs indicate I need professional drain cleaning?

    Slow drains, recurring clogs, gurgling sounds, sewer odors, or multiple backed-up fixtures are common indicators. Professional drain cleaning helps prevent larger issues and restores proper flow.

  • What drain cleaning methods do you use?

    Depending on the issue, we use professional-grade drain augers (snaking) and other industry-approved methods to clear blockages safely. After clearing, we can discuss maintenance tips to reduce future clogs.

  • Do you repair and install water heaters?

    Yes. We provide water heater installation and repair for gas water heaters, electric water heaters, and tankless units. We service a wide range of models and can recommend the right capacity for your home.

  • Should I repair or replace my water heater?

    If your unit is 8–12+ years old, leaking, producing rusty water, or not heating consistently, replacement may be more cost-effective. Newer heaters with minor issues can often be repaired. Our technicians will assess and advise on the best option.

  • Do you service boilers and radiant heat systems?

    Yes. We provide boiler repair, boiler installation, and radiant heat repair for hydronic systems. Our team can diagnose heat loss, circulation issues, air in lines, or control failures and return your system to efficient operation.

  • How can I tell if my boiler needs service?

    Common signs include uneven heating, rising energy bills, unusual noises, frequent cycling, or water leaks. Prompt service helps prevent further damage and restores comfort.

  • Do you install and replace sump pumps?

    Yes. We offer sump pump installation and replacement to protect basements and crawl spaces from flooding. We can also recommend battery backup systems for added protection during power outages.
