Under normal use conditions, toilets are highly durable and can last for decades with minimal maintenance. However, they occasionally develop leaks around the base, leading to significant water damage in flooring and other areas where moisture can seep. Unwanted water causes structural damage and promotes the growth of dangerous mold, mildew, and fungus.

Plumbing presents a complex engineering problem unique to every residential or commercial building. In the rapidly developing world of innovative plumbing and government regulations of water systems, you must select the best professional firm suited to your situation. 

Iron Mountain Plumbing wants to help you be the best-informed customer possible. In this post, we’ll examine the most common answers to what causes a toilet to leak from the bottom in Hurricane, UT. 

Toilet Seal Failure

A toilet seal is found on the bottom of a toilet at the point where it rests on the floor. It is a ring of special wax that forms a watertight seal between the toilet and the flooring surface as a gasket that forms itself to the hardware. 

This inexpensive item usually lasts for many years. However, drying over time or minor manufacturing flaws can lead to loosened or cracked seals that can first show themselves by slowly leaking around the toilet base onto the surrounding floor. 

If you see pooling, you can visually inspect the area between the bottom of the toilet base and the floor for seeping water, apparent cracks, or deteriorated wax. If this is the only problem detected, we can usually resolve the leak by removing the damaged seal with a putty knife, installing a new wax ring, and properly aligning the toilet base.

Our seasonal climate in Hurricane, Utah, involves temperature and humidity fluctuations that can accelerate wax ring deterioration. Sometimes, we see leaks from elsewhere, which we’ll discuss below, that can place additional stress on wax rings and lead to the more advanced breakdown of the seal. You should rely on our expert inspection to ensure that no deeper cause would require us to do more than replace the wax ring.

Toilet Pipe and Hardware Leaks

The plumbing and hardware that make up the toilet system can sometimes fail, leading to leaks that develop as pooling water around the bottom of the toilet. Standard plumbing pipes that bring water to the toilet can corrode or rust, leading to cracks that allow water to run out. If the pooling around the bottom of the toilet appears to be coming from behind a wall near the toilet, that is strong evidence of a leaking or rusted pipe. 

Leaking pipes can be a severe issue, as the water inside them can be under pressure, and small amounts of seeping can rapidly evolve into major leaks that can cause dangerous moisture damage. 

Sometimes the water connections between the incoming pipes and the toilet or the shut-off valve become loose and develop leaks, and a professional should carefully check these as well.

You should also enlist an HVAC contractor to inspect the toilet tank. Leaks sometimes develop between the tank that holds water and the toilet bowl. These allow water to seep to the floor level and pool around the bottom of the toilet. The bolts and gaskets that hold these parts of the toilet system together could malfunction.  

The toilet base is also bolted to the floor. Loose bolts at the base can cause leaks, as they are designed to hold the toilet firmly against the wax ring seal and prevent shifting. 

Toilet Flange Failure

Toilet flanges, sometimes described as floor flanges, are pipe fittings that directly connect the base of a toilet to the drainage system that begins at the floor level. The flange is shaped in a circle and is usually made of rubber, metal, or PVC. It is mounted at floor level around the end of the drain pipe and has connection points for the bolts that hold the toilet firmly against the drainage pipe.

The design of the flange allows the toilet to remain stable. If the bolts directly connected the toilet to the floor, the inherent water intrusion would always lead to moisture damage and leaking sewage.

A broken or loose flange can cause a toilet to leak from the bottom and often make the entire toilet structure unstable. 

Because the bolts on the flange are primarily responsible for bearing the weight of the toilet and users while holding it stationary, they are under stress and sometimes break after years of service. If you see a leak around the bottom of your toilet and it rocks or feels loose when you press on it, there is a good chance the flange or the bolts holding it together cause the leak.

Sometimes, all that is needed is for a professional to tighten the bolts, but they must inspect them thoroughly for any damage that would require replacing them.

Toilet Bowl Cracking

While toilet bowls are made from durable materials, they sometimes develop cracks through wear and tear or unusual stress caused by improper or faulty installation. A cracked toilet bowl can cause a toilet to leak from the bottom.

Improperly fitted or worn toilet seats can cause impacts that eventually damage toilet bowls. Of course, if something heavy or sharp falls on a toilet, an immediate crack can occur. Porcelain is tough, but it’s certainly not indestructible.

The first cracks on toilet bowls are usually hairline breaks that are hard to see with the naked eye. However, water seeps through tiny fissures, and the resulting pressure causes small cracks to spread and grow larger. Eventually, leaks can develop, leading to unwanted moisture on the floor around the toilet.

If there are any visible cracks around the outside of the toilet, they could be evidence of ordinary wear and tear. Any deeper breaks or cracks are almost certain to lead to water leaks. Because of their design and materials, toilets are difficult to repair. If professionals see evidence of cracking causing leakage, they will consult with you about replacing the toilet with a new model. 

Drain Line Clogs

If nothing above the toilet flange is causing the toilet to leak from the bottom, the problem could lie with a clogged drain line. The drain line begins at floor level, carrying waste out of your building and to a sewer line or septic system. When drain lines are clogged, the resulting pressure can press directly back against the toilet flange and seal, leading to leaking around the bottom of the toilet onto the floor and in the subflooring. 

A leak around the bottom of a toilet caused by a clogged drain line can be a small sign of a much more significant problem. It can indicate an issue with the part of your plumbing system that safely transports waste away from your home or commercial building.

This plumbing issue requires at least two essential repairs: first, professionals must identify and clear the drain line clog, and second, they must repair any damage to the toilet seal or flange.

Of course, clogs in sewage drainage are potentially highly damaging and hazardous. Experts must address these issues immediately to permit the safe usage of your toilet and ensure the integrity of your overall plumbing system. 

Condensation Buildup

Water condensation can also cause water to pool around the bottom of a toilet. While standing water is often the result of a leak, condensation occurs as water vapor in the atmosphere accumulates on a surface as droplets. 

Of course, bathrooms typically experience the highest humidity level in our homes, especially in those where family members take hot showers. We often see that humidity leads to condensation on the porcelain of toilet bowls, which then trickles down to the floor level and forms a puddle. 

The best remedy for excess condensation is to run the bathroom exhaust fan when using hot water. Leaving the bathroom door open when possible while taking a hot shower also helps move the excess humidity out of the bathroom.
