Can I replace a toilet fill valve myself without professional help?

Some homeowners can replace a toilet fill valve, but call a pro if leaks continue or the source is unclear. Our plumbers repair or replace tank components, then confirm the real problem with on-site diagnosis and upfront pricing.

Quick checks:

• Use food coloring to test for tank-seal leaks.
• Add color to the bowl and flush to check the wax seal.
• If the toilet is “sweating,” insulation is the fix, not a valve.

We serve Denver, Highlands Ranch, and Aurora.
