Heise's Plumbing recently completed a professional toilet repair service in the Colma area of South San Francisco, California.
The Problem
The homeowner reported a constantly running toilet that was causing high water usage.
Our Inspection
Our plumber inspected the inner components of the toilet tank and diagnosed a deteriorated flush valve flapper along with a malfunctioning fill valve that failed to shut off.
Our Solution
We rebuilt the tank assembly by installing a high-quality, corrosion-resistant fill valve and a flexible silicone flapper to ensure a tight seal. We also replaced the shutoff valve connection with a braided stainless steel line to prevent future leaks.
Final Results
Finally, the system was tested and all work was verified for safe, reliable operation.
Common Signs of Toilet Plumbing Issues
If you experience any of the following, your toilet needs professional repair:
- Continuous Running: Water constantly runs into the bowl, increasing your water bill.
- Weak Flush: The toilet does not flush completely or takes multiple flushes to clear.
- Base Leaks: Water pooling on the floor around the base of the toilet.
- Loose Handle: Flashing mechanism is loose, stiff, or fails to engage the fill valve.
Toilet Repair vs. Toilet Replacement
Internal parts like flappers, fill valves, and flush levers are easy and cost-effective to repair. However, if the porcelain bowl or tank has cracks, or if the unit is extremely old and inefficient, installing a modern water-saving toilet is the better option.
Plumbing Considerations in Colma
Colma features mature tree landscaping and older residential construction, which can increase the risk of tree root intrusions in underground sewer cleanouts and lateral pipes.
