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

Yes, you can replace a toilet fill valve yourself if you can shut off the water and follow the part’s directions. If the shut-off won’t close, parts are corroded, or you’re unsure of valve type, call a pro. We offer a Free Toilet Repair Diagnostic, same-day service if booked by 6 PM, and trucks stocked with common parts. S.A.M. members get 15% off repairs and a 2-year labor and limited parts warranty.

Quick checks:

• Close the toilet’s emergency shut-off.
• Match the fill valve to your toilet.
• After install, do a toilet dye test.
