My plumber charged $160 to fix the cistern on my toilet — but created another problem. Do I pay again?
Short answer: usually no, if the new issue was caused by the repair or is part of the same fault. You might pay again if it’s unrelated, a new part is now required, or the problem stems from old or customer‑supplied parts that the plumber warned you about. Here’s how to tell the difference, what to say, and how to escalate if you need to.
Start with a quick diagnosis
– Timing: Did the new problem start immediately or within a day or two of the repair? The closer it is, the more likely it’s connected and should be fixed at the plumber’s expense.
– Location: Is the issue in the same assembly the plumber worked on (cistern/tank, fill valve, flush valve, tank-to-bowl gasket, supply line, shutoff)? If yes, it’s likely on them.
– Symptom chain: Common post-repair issues include:
– Constant running or slow fill after replacing a fill/flush valve (misadjustment, debris in valve, faulty part).
– Drip at the shutoff/stop valve after it was turned for the first time in years (disturbed packing). Plumbers should warn this is likely and either re-pack it or recommend replacement. If they overtightened and cracked it, that’s on them.
– Leak at tank bolts or tank-to-bowl gasket after valve work (improper seating/torque).
– Water hammer or loud refill (fill valve not set up with anti-hammer insert or pressure not adjusted).
– Cracked cistern from overtightening bolts (installer error).
– Paper trail: Check your invoice/quote for:
– Scope of work (what exactly they agreed to fix).
– Any notes about “no warranty on customer‑supplied parts,” “old/brittle fittings may fail,” or “recommend replacement.”
– Warranty terms (many plumbers offer 30–90 days on workmanship; consumer law often implies “reasonable care and skill” regardless of written terms).
A simple rule of thumb
– Don’t pay again if:
– The new problem is a direct result of their work or parts they supplied (misdiagnosis, poor installation, damage while working, failure to test).
– The original fault wasn’t actually fixed, or the fix failed within a reasonable time.
– You may need to pay (perhaps for parts only) if:
– The issue is different or unrelated (e.g., a wax ring or bowl crack discovered later when only the cistern was serviced).
– A new part fails that you supplied yourself.
– They warned an old valve or brittle fitting might fail when operated and you declined replacement.
– The callback is outside the stated or customary workmanship window and there’s no evidence of poor work.
How to approach the plumber (what to say)
– Call or message within 24–48 hours. Keep it factual and calm.
– Script:
– “Hi [Name], you repaired my toilet cistern on [date] for $160. Since then I’ve had [specific issue: leak at the tank bolts/continuous running from the overflow]. It started [immediately/next day] and wasn’t there before. Could you come back for a no‑charge callback under your workmanship warranty to make it right? I’ve attached photos/video.”
– Ask them to:
– Inspect and test in your presence (several flushes, paper towel test at joints).
– Explain cause and remedy before any new chargeable work.
– If they propose new parts, request itemized pricing and to keep/review the failed part.
Negotiating outcomes
– Best case: No‑charge callback for labor and any adjustment/reseal; they cover or swap the faulty part if they supplied it.
– Middle ground: Labor at no charge, you pay for a genuinely new/unrelated part (e.g., replacing an old shutoff valve that started leaking and was not part of original scope, after they warned of the risk).
– If the original repair didn’t resolve the issue: Ask for a redo at no charge or a partial/full refund of the $160 if they misdiagnosed and can’t fix it.
Evidence that helps you
– Photos/video of the symptom and the areas they touched.
– A written timeline (when work was done, when the problem appeared).
– The original invoice/quote and any texts/emails.
– The failed part, if replaced.
Region‑by‑region consumer rights (plain language)
– United States: Contractors must perform in a “workmanlike manner.” If their work causes damage or doesn’t fix the problem, you can demand they remedy it. Many states have licensing boards for plumbers; you can also use small claims court. If you paid by credit card and they refuse a warranted callback or refund, consider a dispute/chargeback with documentation.
– United Kingdom: Consumer Rights Act 2015 requires services be provided with reasonable care and skill. You can insist on repeat performance at no extra cost or a price reduction if they don’t fix it within a reasonable time. Citizens Advice and Trading Standards can assist; some firms are covered by ADR schemes.
– Australia: Under the Australian Consumer Law, services must be rendered with due care and skill and be fit for purpose. You’re entitled to remedies for failures—repeat service, refund, or compensation depending on severity. State Fair Trading/Consumer Affairs can help.
– New Zealand: The Consumer Guarantees Act gives similar rights; services must be carried out with reasonable care and skill. Disputes Tribunal is the usual forum for small claims.
When the plumber can fairly charge again
– The revisit is for a genuinely different fault unrelated to their work.
– The issue involves old or failing infrastructure they didn’t touch, they warned you about it, and it gave up after the job.
– You supplied the part that failed.
– You’re far outside any reasonable callback period without evidence of substandard workmanship.
When to escalate
– If they refuse a reasonable no‑charge callback for a problem clearly linked to their work:
– Send a short written complaint summarizing facts, photos, and your requested remedy with a deadline (e.g., 7 days).
– Post a fair, factual review only after giving them a chance to fix it.
– File with your local consumer protection agency/licensing board.
– Consider a credit card dispute or small claims action; ask for the cost to repair properly and any proven water damage.
Special notes
– Renters: Report issues to your landlord/agent and let them deal with the plumber. Don’t withhold rent without legal advice.
– Before‑and‑after testing: At the end of any cistern work, ask the plumber to flush several times, check for drips at the tank bolts, tank‑to‑bowl gasket, supply line and shutoff, and to demonstrate proper water level and quiet refill.
Bottom line
– If the new problem appeared right after the $160 cistern repair and is in or near the parts they worked on, you shouldn’t have to pay again. Call it a “callback under workmanship warranty,” be specific about the symptom, and ask them to make it right. Pay only if the revisit addresses a legitimately separate issue or a new part outside the original scope. Keep records, be firm but fair, and escalate if needed.
