Drain Cleaning and Clog Busting Options
Our Ongaro & Sons plumbers will assess the problem and recommend the best solution for your plumbing system. The techniques we use are designed specifically for the size and location of the clog. We typically remove clogs that form in your bathroom, kitchen, and floor drains with a drain-cleaning cable machine, though we can use hydro jetting methods when necessary.
Drain Maintenance You Can Do at Home
We recommend leaving drain and sewer line cleaning and flushing to professionals, like our experts at Ongaro & Sons. However, you can help keep your plumbing in top shape by treating it with a little TLC.
Here are some ways you can avoid clogging your drains and sewer line:
Prevent Clogs With Regular Maintenance
You don’t have to wait until a clog causes a toilet or drain backup to call Ongaro & Sons for help. We recommend regular drain cleaning and sewer line maintenance to prevent waste buildup and clogs.
Schedule periodic drain cleanings to keep water flowing in your sinks, toilet, and shower. Consider inspecting your sewer line every few years, especially if large trees grow on your property. We can identify emerging problems, such as root growth, by snaking a camera through the sewer line.
Busy lives can affect remembering routine home system maintenance. That’s why we offer the Ongaro Maintenance Plans to remove all the stress of keeping tabs on your home maintenance. Our plans save you money, offering priority service, friendly reminders, and other perks. Sign up today!
Only flush toilet paper down your toilet—avoid flushing wipes, feminine hygiene products, paper towels, or anything labeled “flushable.” These items can clog pipes, damage plumbing, and lead to costly backups or sewer line issues.

Frequently Asked Questions
Chemical drain cleaners can effectively clear minor clogs but come with risks. They can be harsh on your plumbing, potentially causing damage to pipes over time, especially if used frequently. Additionally, they can be hazardous to handle and may release toxic fumes. Mechanical tools like plungers or drain snakes are safer alternatives.
For persistent or severe clogs, it’s generally more effective to use professional drain cleaning services. These services use methods like snaking or hydro-jetting to clear blockages without the risks associated with chemicals.
