Common Toilet Problems and When to Call a Plumber in Des Plaines

Toilets are one of those fixtures you count on every single day, and when something goes wrong, it is hard to ignore for long. Some issues are simple enough to fix yourself. Others are signs of a bigger problem that will only get worse if you wait.

Here is a practical look at the most common toilet problems, what causes them, and when it makes sense to pick up the phone and call a professional plumber in Des Plaines.

Running Toilet

A toilet that keeps running after the flush cycle is one of the most common complaints from homeowners. It can waste up to 200 gallons of water per day, which adds up fast on your water bill.

• A worn or warped flapper that no longer seals against the flush valve
• A float set too high, causing water to spill into the overflow tube
• A faulty fill valve that keeps cycling without shutting off
• Mineral buildup from hard water common in the Des Plaines area, coating internal parts and preventing a proper seal

Replacing the flapper is an easy DIY fix and costs just a few dollars. If the toilet keeps running after that, the fill valve or flush valve seat likely needs professional attention.

Weak or Incomplete Flush

If your toilet struggles to clear the bowl with a single flush, the problem is usually one of a few things. Mineral deposits can clog the small rim holes under the bowl rim, reducing water flow. A partially closed shutoff valve or a worn flapper that closes too quickly can also cause a weak flush.

In older Des Plaines homes, low-flow toilets installed in the 1990s are notorious for this issue. Cleaning the rim jets with a small brush and a descaling solution sometimes helps, but persistent weak flushing often means the toilet itself is past its useful life.

Toilet That Clogs Frequently

An occasional clog is normal. A toilet that clogs every week is not. Frequent blockages usually point to a deeper issue than too much toilet paper.

• A partial blockage in the trap or drain line that never fully clears
• Root intrusion in older sewer laterals, which is common in established Des Plaines neighborhoods with mature trees
• A low-flow model that simply does not have enough flush power for your household
• Non-flushable items, including wipes labeled as flushable, that accumulate over time

If a plunger does not solve it within a couple of attempts, or if multiple drains in the home are slow at the same time, you likely have a drain line issue that needs professional diagnosis.

Toilet That Rocks or Moves

A toilet that shifts when you sit on it is more than just annoying. Movement at the base breaks the wax ring seal underneath, allowing sewer gases and even water to leak beneath the floor.

Sometimes the fix is simply tightening the floor bolts on either side of the base. But if the toilet has been rocking for a while, the subfloor underneath may already have water damage or rot, especially in bathrooms with tile over wood framing. This is a repair that should not wait.

Water Leaking Around the Base

Pooling water at the base of a toilet after flushing almost always means the wax ring seal has failed. This seal sits between the toilet and the floor flange and prevents water and sewer gases from escaping.

A failed wax ring is not a DIY job for most homeowners. The toilet needs to be removed, the old seal cleared away, and a new ring properly set before reinstalling. If the flange itself is cracked or corroded, that adds another layer of repair.

Frozen or Cracked Tank Components in Winter

Des Plaines winters are cold, with temperatures regularly dropping well below freezing from December through February. Toilets in unheated spaces like garages, additions, or poorly insulated bathrooms on exterior walls are vulnerable to freezing supply lines.

A frozen supply line will leave you with no water to the toilet at all. If the line cracks from the pressure of ice expanding inside, you can end up with a slow leak or a sudden burst when it thaws. Never try to thaw a frozen pipe with an open flame. Call a plumber to handle it safely.

Phantom Flushing

If your toilet seems to refill on its own without anyone flushing it, water is silently leaking from the tank into the bowl. This is almost always a flapper issue. You can confirm it by adding a few drops of food coloring to the tank and waiting 10 minutes without flushing. If color appears in the bowl, the flapper is leaking.

Replacing the flapper is inexpensive and straightforward. If the problem continues after replacement, the flush valve seat may be worn or pitted and will need to be replaced as well.

When to Call a Plumber

Some toilet repairs are reasonable for a handy homeowner to tackle. Others carry real risk of making the problem worse or causing water damage.

• Water leaking at the base after flushing
• A toilet that rocks or shifts on the floor
• Frequent clogs that do not clear with a plunger
• Multiple slow drains throughout the home at the same time
• Gurgling sounds from the toilet when other fixtures drain
• Any issue involving the floor flange, drain line, or supply line
• Frozen or burst supply lines during winter

Catching these problems early almost always costs less than dealing with the water damage or sewer issues that follow when they are ignored.
