Common Toilet Repairs We Perform

From inefficient faucets to leaking pipes, our San Marcos plumbers have seen their fair share of bathroom plumbing problems. Toilets are simple in function, but a lot can go wrong behind the scenes. Our team handles a full range of repairs with the care and precision your bathroom deserves.

Leaking Toilet Base

If you notice water pooling around the base of your commode, don’t ignore it. A leaking base can occur from a failing wax ring, loose bolts or a cracked flange. Over time, this water loss can lead to moisture damage, mold growth or floor rot. Our plumbers will find the source of the leak and seal it properly to protect your home.

Toilet Clogs

Clogs are one of the most common calls we get — for good reason. A slow or blocked toilet can be anything from an annoyance to an emergency plumbing repair. While a plunger might do the trick once in a while, consistent clogs often point to a deeper issue.

Common causes of these blockages include:

• Flushing too much toilet paper
• Non-flushable wipes or feminine products
• Toys or foreign objects (common in homes with kids)
• Low-flow toilets with poor pressure
• Underlying drain line blockages

We use professional-grade tools to remove clogs safely and completely — without risking damage to your fixtures or pipes.

Toilet Flange Repairs

The flange connects your commode to the drainpipe and helps secure it to the floor. If it’s cracked, rusted or improperly installed, you’ll likely deal with leaks, rocking bases or foul smells in the bathroom. Our team can correct faulty flanges and ensure a secure, long-lasting connection to prevent recurring problems.

Phantom Flushing

If you hear your toilet refilling randomly — even when no one’s used it — you’re likely dealing with phantom flushing. This usually occurs when water gradually leaks from the tank and into the bowl due to a worn-out flapper, faulty fill valve or deteriorated tank parts.

While it might seem minor, phantom flushing wastes water and increases your water bills over time. Oasis can inspect the internal components of your fixture, stop the leak and restore proper operation.

How Long Do Toilets Last?

Most toilets can last 15-25 years with proper care. However, components like flappers, handles and seals often need replacement sooner. If your toilet is older than 20 years and showing signs of wear, replacing it with a newer, high-efficiency model can save water, reduce repair costs and improve your bathroom’s overall comfort.
