A malfunctioning toilet is more than just an inconvenience — it can waste water, increase your utility bill, and even cause serious water damage. If you're dealing with toilet issues in Central Texas, knowing when to try a simple fix and when to call a professional plumber can save you time, money, and frustration.

At OnCall Plumbing, we provide expert toilet repair and plumbing services throughout Liberty Hill, Bertram, Leander, Burnet, Marble Falls, Bastrop, Austin, and surrounding areas. Here are the five most common toilet problems homeowners face — and when it’s time to call a licensed plumber.

1. Constantly Running Toilet

A toilet that won’t stop running can waste hundreds of gallons of water per day.

Common Causes:

• Worn flapper

• Faulty fill valve

• Improper chain length

• Tank water level imbalance

While replacing a flapper is a simple DIY fix, if the running continues or internal parts keep failing, you may have a larger issue with the tank mechanism.

Call OnCall Plumbing if: The toilet continues running after replacing basic components or if water is overflowing into the overflow tube.

2. Frequent Clogs

Occasional clogs happen — but frequent blockages are a red flag.

Possible Reasons:

• Drain line buildup

• Low-flow toilet issues

• Sewer line obstruction

• Tree root intrusion

If plunging doesn’t solve the issue or clogs keep returning, you may have a deeper blockage in your drain or sewer line.

Call OnCall Plumbing if: Clogs occur repeatedly or you notice gurgling sounds in other drains.

3. Leaking Around the Base

Water pooling around the base of your toilet often signals a failed wax ring seal.

What This Means:

• The toilet seal may be broken

• Bolts may be loose

• Flange may be damaged

Ignoring this issue can lead to subfloor damage, mold growth, and costly repairs.

Call OnCall Plumbing immediately if:You see water around the base or notice flooring becoming soft or warped.

4. Weak or Incomplete Flush

If your toilet doesn’t flush completely, you may be dealing with:

• Mineral buildup in rim jets

• Partial drain blockage

• Low water pressure

• Failing internal components

Austin-area homes often experience mineral buildup due to hard water, which can impact flush performance.

Call OnCall Plumbing if: Cleaning doesn’t improve flush strength or if waste frequently remains after flushing.

5. Toilet Won’t Stop Refilling

If you hear water refilling long after flushing, there may be:

• A slow tank leak

• Faulty fill valve

• Internal tank crack

This not only wastes water but increases your water bill.

Call OnCall Plumbing if: Refilling happens constantly or your water bill suddenly spikes.

When to Replace Instead of Repair

Sometimes repairs aren’t the most cost-effective option. If your toilet is:

• Over 15–20 years old

• Cracked

• Frequently clogging

• Inefficient (high water usage)

A professional toilet replacement may save you money long-term.
