Toilet Repair & Installation
Toilet Repair & Installation in Marin, Sonoma & Napa County
Has the “handle jiggle” become your go-to fix for a toilet that just won’t stop running? Do you find yourself flushing with a bucket of water to compensate for a weak or inconsistent flush?
Are you lifting the tank lid to reattach the chain to the flapper valve, again?
While these quick DIY fixes can help in the short term, they often mask more significant issues that will only get worse over time. Eventually, even the most patient homeowner reaches a point where patchwork solutions just won’t cut it anymore.

Signs Your Toilet Needs Repair
Ongaro & Sons will address your plumbing issue immediately because we know how inconvenient a malfunctioning toilet can be. When you notice these signs, your toilet needs attention:
- If your toilet flushes weakly or slowly and doesn’t clear the bowl, clogged rim jets or mineral buildup in the siphon hole could be the cause. An improperly adjusted toilet float inside the tank may also affect flushing performance.
- Water pooling around the base of your toilet usually signals a broken seal or cracks in the porcelain. Prompt repair is essential to prevent water damage to your floor and surrounding areas.
- If you find yourself constantly jiggling the handle to get the toilet to flush, it’s likely time to replace the flapper valve, which controls the water flow from the tank to the bowl.
- A worn or malfunctioning fill valve can prevent the toilet bowl from filling properly after a flush, affecting the toilet’s ability to function efficiently.
- An overflowing toilet is often a sign of a clog in the drain line. Immediate attention is needed to prevent water damage and restore proper function.

Installing a New Toilet
How do you know when it is time to replace your toilet? Age is a significant factor when weighing repairs versus replacement. Your toilet may continue to operate after 20 years, but it may also waste water and cost you money.
The EPA says toilets are the main source of water use in homes. Older, inefficient toilets that use more than six gallons per flush are a significant source of wasted water.
The plumbing pros at Ongaro & Sons can help you choose a quality toilet with a strong flush and water-saving efficiency. Replacing your old toilet is a cost-effective alternative to frequent repairs.
Before beginning any job, we discuss repair and replacement options. We tailor our recommendations to your specific needs and budget. We make our financing options (subject to approved credit) as convenient as possible.

Toilet Maintenance Tips
You can prevent common toilet problems by making maintenance a habit in your home. Avoid flushing wipes, feminine hygiene products, cotton swabs, and other paper items into your plumbing system, even if the labeling claims they are flushable. They are likely to clog your toilet or pipes.
Take a close look at your toilet. Inspect for wet areas or water accumulation at its base, the signs of a leak. Add a few drops of food coloring to your tank, wait about 15 to 30 minutes, and check the bowl. If the bowl contains colored water, your tank is leaking.
Test the valve that shuts off water to your toilet. Consider replacing it if it is rusty or resists movement.
