Common Toilet Problems We Fix
Toilets are simple machines, but when something goes wrong, the symptoms can range from annoying to messy. Here are the issues we see most often.
Running Toilet
A toilet that runs continuously or cycles on and off is usually a flapper, fill valve, or overflow tube issue. It wastes water constantly and can add real cost to your water bill. This is one of the most common calls we get, and it is typically a quick repair.
Frequent Clogging
A toilet that clogs more than once a month often has a partially blocked trapway, a buildup of mineral deposits in older models, or a venting issue in the drain system. Older low-flow toilets from the 1990s are particularly prone to weak flush performance.
Weak or Double Flush
If the bowl does not clear on the first flush, or if you have to hold the handle down to get a full cycle, the problem could be low tank water level, a worn flapper that drops too early, or clogged rim jets. Double flushing wastes water and usually signals an internal component issue.
Leaking at the Base
Water pooling at the base of the toilet typically means the wax ring seal has failed. This seal sits between the toilet and the floor flange and keeps wastewater from seeping out. A failed wax ring should be replaced promptly to avoid water damage to your subfloor.
Toilet Giving You Trouble?
Toilet Replacement and Installation
Sometimes repair is not the best call. If your toilet is old, inefficient, cracked, or constantly needing attention, replacing it is often the smarter long-term choice.
Modern toilets use significantly less water per flush while delivering stronger performance than the low-flow models from 20 years ago.
We install new toilets from trusted manufacturers, set them on a fresh wax ring and new supply line, and verify proper flush performance and fill levels before leaving.
If your floor flange is corroded or damaged, we address that during the install.
Part of Your Bathroom Plumbing System
Toilet problems sometimes connect to broader plumbing issues. A toilet that gurgles when you run the bathroom sink may have a venting problem. A toilet that backs up along with the shower could indicate a main-line issue rather than a toilet-specific clog.
Our technicians look at the full picture, not just the toilet in front of them. If the problem extends beyond the fixture, we will let you know what else is going on and what your options are.
Frequently Asked Questions About Toilet Repair
Should I repair my toilet or replace it?
If the toilet is less than 10 years old and the issue is a running flapper or faulty fill valve, repair makes sense. If it is older, frequently clogs, has cracks in the porcelain, or uses more than 1.6 gallons per flush, replacement is usually the better value.
Why does my toilet keep running after I flush?
The most common cause is a worn flapper that no longer seals properly against the flush valve seat. A faulty fill valve or an improperly adjusted float can also cause continuous running. Both are straightforward repairs.
Can a running toilet really affect my water bill?
Yes. A running toilet can waste 200 gallons or more per day. Over a month, that adds up to thousands of gallons and a noticeably higher water bill. Fixing it quickly saves money.
What does it mean when my toilet gurgles?
Gurgling usually indicates a venting issue or a partial blockage in the drain line. Air that should escape through the vent stack is instead being pulled through the water in the toilet bowl. This can sometimes point to a main-line problem if other fixtures are affected.
How long does a toilet installation take?
A straightforward toilet replacement typically takes about an hour. If the floor flange needs repair or the supply line needs updating, it may take a bit longer. We provide a clear time estimate before starting.
