Replacing or installing a toilet can be a challenging DIY project. However, many people successfully tackle this task every day! If you don’t feel confident in your DIY skills, it’s worth considering calling Radiant Plumbing and Air to professionally handle the replacement or installation of a new toilet in your home.

Toilets can leak for various reasons. Common causes of leaky toilets include worn-out wax rings, loose or faulty bolts, cracked tanks and bowls, broken gaskets or flanges, and sometimes just condensation from a high humidity climate. If you have persistent leaking and notice an increase in your water bill, contact Radiant Plumbing and Air. We can help detect the source of the leak and prevent it from becoming a bigger issue.

There are a few reasons why your toilet might not flush. It could be blocked or have low water levels in the tank. You might have issues with the flapper itself or the chain to the flapper. Lift the tank lid and inspect the components. If the running stops, you have found the source of the problem. If not, look below and behind your toilet to locate the water shut-off valve. Turn this valve tightly until it closes, and then call Radiant so we can come and find and fix your running toilet.

Signs of a damaged toilet flange, such as wobbling, base leakage, foul odors, or difficulty flushing, may indicate underlying issues with your bathroom’s functionality. If you observe any of these symptoms, your toilet flange could be the culprit. To address this, the first step is to remove the toilet from the floor to access the flange beneath.

Repairing a damaged toilet flange can be facilitated with kits available at major home stores. These kits provide the necessary components to fix the flange and restore stability to your toilet. However, if you find the prospect of handling plumbing repairs overwhelming, consider enlisting the expertise of professionals.

At Radiant Plumbing and Air, we have been resolving issues with toilet flanges and more since 1999. Our team of experts is well-equipped to handle the complexities of toilet repairs, ensuring a swift and effective solution to your plumbing concerns. Don’t hesitate to contact us for reliable assistance in restoring your bathroom’s functionality.

In the course of day-to-day use, toilet parts can become worn out and may break. This includes the components that secure the toilet firmly to the floor, such as bolts, wax rings, and the flange. However, if there has been a persistent leak in your home, it is possible that the subfloor could be damaged, leading to rotting and an uneven bathroom floor. We recommend calling us to assess the situation. We will provide you with a free estimate for repairing or replacing the toilet and the surrounding parts.

In most cases, repairing a cracked toilet bowl or tank is not recommended. Once a crack appears, the structural integrity is compromised, posing potential risks and hygiene concerns. If you spot a crack, contact Radiant Plumbing and Air promptly. Our team specializes in quick and professional toilet repairs, ensuring a timely resolution to your bathroom issues.

If your toilet tank is not filling up properly, it may be due to issues with the fill valve, float, or other components. Start by removing the tank lid and inspecting the float, flapper, and water level adjustment screw. Make adjustments as needed. If the problem persists or if you notice water leaking around the base of your toilet, it’s crucial to act promptly. Contact Radiant Plumbing and Air right away. Our expert team will not only address the immediate issue but also prevent potential damage to your home. Your peace of mind is just a call away.
