When Should You Replace a Toilet Instead of Repairing It?

Toilets are built to last — but not forever. And when something goes wrong, the big question is always:
Should we try to fix it, or just replace the whole thing?

At EPM, we’ve repaired and replaced thousands of toilets across Exeter and the wider Devon area. Sometimes a £10 part solves the issue. Other times, the fix takes longer — and costs nearly as much as a new unit.

Here’s how to tell when it’s worth repairing… and when replacement makes more sense.

When a Repair Makes Sense

We usually recommend a repair if:

• The toilet is relatively modern (last 10–15 years)

• The issue is isolated (e.g. fill valve, flush button, leaking seal)

• The cistern or pan is accessible and undamaged

• The ceramic isn’t cracked or stained

• Replacement parts are available and affordable

Common repair jobs include:

• Replacing a faulty syphon or flush valve

• Fixing a constantly running toilet

• Changing a split flush button

• Replacing the inlet valve or ballcock

• Resealing a leaking pan connector or base

These are often quick, low-cost fixes — and we carry many parts on the van for same-day repairs.

When It’s Better to Replace the Toilet

Here’s when we usually suggest a full replacement instead:

1. Cracked or Damaged Pan or Cistern

Even small cracks in the ceramic can lead to leaks, smells, or complete failure. Once it’s cracked, it’s a replacement job.

2. Constant Problems or Multiple Fittings Failing

If we’re fixing one issue and two more show up — that’s a red flag. Old toilets with worn-out internal fittings can keep costing you.

3. Outdated or Unreliable Mechanisms

Some older models have discontinued parts, difficult access panels, or awkward flush systems. A new toilet with modern fittings is often quicker and cheaper in the long run.

4. Poor Water Efficiency

Older toilets can use up to 13 litres per flush — compared to just 4–6 litres on new dual-flush models. If you’re already considering work, this is a great reason to upgrade.

5. You’re Renovating the Bathroom

If tiles are coming up, flooring is changing, or the bathroom layout is shifting, it usually makes sense to fit a new toilet while access is easy.

Costs: Repair vs Replace

Typical costs in and around Exeter:

• Repairs (parts + labour): £90–£180 depending on access and parts

• Full replacement (supply and fit): £220–£350
  (More if you're upgrading to wall-hung or designer models)

We'll always give you an honest estimate first, and we’ll never push for replacement if a simple fix will do.
