Rusting Toilet Tank Bolt Causing a Leak
On a recent home inspection in Las Vegas, we found a rusting bolt inside a toilet tank that appeared to be contributing to a leak. Water was also affecting the flooring or subflooring around the toilet.
It's an easy issue to overlook because the hardware is inside the tank and isn't normally visible during everyday use. But even a relatively small plumbing leak can cause damage if it continues long enough.
What This Means For You
The bolts and other hardware inside a toilet tank help secure the tank to the toilet bowl and maintain a watertight connection.
When that hardware begins to corrode, the seal can deteriorate and allow water to leak from the tank. There may also be additional sources of leakage that aren't immediately obvious, so it's important to determine exactly where the water is coming from.
A small leak doesn't necessarily mean extensive damage has occurred, but moisture around the base of a toilet can affect flooring, subflooring, and other materials if left unaddressed.
Why It Matters
Plumbing leaks are one of those problems that can start small and become much more expensive when they're allowed to continue.
Water that gets into flooring or subflooring can cause deterioration and create conditions where mold growth is possible. That's why water leaks found during an inspection may warrant additional evaluation, including mold sampling and testing.
The good news is that the visible issue in this case is relatively straightforward to address. Catching it early can help prevent a minor plumbing repair from turning into a larger flooring or subfloor repair.
What We Typically Recommend
We recommend having a qualified plumber evaluate the toilet and replace the corroded hardware with corrosion-resistant materials, such as brass or stainless steel.
The hardware should be properly installed and sealed to prevent future leakage. If the corroded hardware is difficult to remove, a plumber can determine the best way to make the repair without damaging the toilet.
Any evidence of water damage around the toilet should also be evaluated to determine whether additional repairs are necessary.
Main Takeaway for Las Vegas Home Buyers
A little rust inside a toilet tank may not seem like a big deal, but it can be an early warning sign of an active plumbing leak.
During a home inspection, we're looking beyond the things that are immediately visible. Small plumbing issues like this can be easy to miss during a typical walkthrough but important to address before they cause more extensive damage.
If you're buying a home in Las Vegas, a professional inspection can help identify plumbing leaks and other maintenance concerns before they become someone else's expensive repair.
