Unhook the old flapper

Unclip the chain from the flush lever arm, then slide the flapper's ears off the pegs on the overflow tube.

⚠ Before you continue

Water should already be off at the supply valve. If the tank refills on its own, stop and re-check step 2.

Why Chamfer

Calling a pro for every small fix adds up. Fast.

Most home repairs aren't hard — they're just unfamiliar. The part is cheap; what you're paying for is someone who's done it before. Chamfer gives you that experience, one step at a time.

How it works

Like having a patient friend who's fixed everything before.

No jargon, no 40-minute videos, no guessing whether that forum answer applies to your house.

1

Show Chamfer what's wrong

Snap a photo of the problem, describe it in plain English, or browse the guide library — whatever's easiest.

2

Get a guide sized to you

Clear steps with the tools and parts you'll need up front — written and vetted by real people, not generated on the spot.

3

Do it with a safety net

Ask questions mid-job and get answers that know the exact step you're on. Risky steps come with a built-in stop sign.

Point and fix

Don't know what it's called? Take a picture.

Snap the drippy valve, the tripped breaker, the mystery switch. Chamfer identifies what you're looking at, figures out what's likely wrong, and drops you straight into the right guide — no searching, no guessing at plumber vocabulary.

Compression shutoff valve

That drip at the stem usually means a worn packing washer — a $2 part and a 20-minute fix.

Safety first

Some jobs you shouldn't DIY. Chamfer tells you which.

Confidence comes from knowing where the line is. Chamfer is honest about it.

  • Real guides, not AI guessesThe AI's job is finding the right fix. The instructions themselves are written and vetted by people who've done the repair — never generated on the fly.
  • Safety interceptsBefore any risky step — gas, mains electricity, structural — Chamfer stops and makes sure you're ready.
  • "Call a pro" honestyWhen a job is genuinely beyond DIY, Chamfer says so instead of walking you off a cliff.
  • Answers in contextThe AI helper sees which guide and step you're on, so its advice fits your actual situation.

Ask Chamfer
The shutoff valve won't turn — should I force it?
Don't force it — older valves can snap and flood the room. Try gently working it back and forth a few degrees at a time. If it's stuck solid, use your home's main shutoff instead. Want me to show you where that usually is?
Yes please
Usually it's where the water line enters the house — check the basement wall facing the street, or near the water heater…
