🛠️ Step-by-Step Guide to Fix a Running Toilet

Step 1: Diagnose the Issue

Quick Steps

  • Remove the tank lid carefully and set aside.
  • Observe: Is water flowing into the bowl non-stop? Is the tank constantly refilling?
  • Look for common signs: flapper not sealing, fill valve never shutting off, chain too tight or tangled. (The Home Depot)

Time: 5-10 minutes

Step 2: Replace the Flapper

Quick Steps

  • Turn off water supply valve behind toilet.
  • Flush toilet and hold the handle down to empty tank.
  • Disconnect chain, remove old flapper; clean valve seat.
  • Install new flapper, reconnect chain with about ½ inch slack. Test for seal. (Legacy Plumbing)

Cost (LA):

  • DIY parts ~$10-$20
  • Pro installation ~$120-$180 for homes; higher for high-use restrooms
    Time: ~20-45 minutes

Step 3: Adjust or Replace the Fill Valve

Quick Steps

  • If tank keeps filling, lift float arm or cup float; if it stops, just adjustment is needed.
  • Lower float (for ball-type float, bend metal arm; for cup-type, move clip down).
  • If water still runs, turn off supply, drain tank, remove fill valve, install new one per manufacturer instructions. (The Home Depot)

Cost (LA):

  • DIY parts ~$25-$50
  • Pro installation ~$160-$250 (home); ~$300+ (business application)
    Time: ~30-60 minutes

Step 5: Final Testing & Preventative Maintenance

Quick Steps

  • Ensure no continuous fill, no hisses, and that bowl water-level is correct.
  • For businesses, record service date and plan periodic checks every 6-12 months.

Why it matters: Ongoing maintenance stops hidden leaks, avoids high water bills, and preserves property value.
