How much does it cost to fix a running toilet?

A standard running toilet repair costs £80 to £150 in the Exmouth area, including parts. The most common cause is a worn flush valve, which costs £30 to £50 in parts and 30 to 60 minutes of labour to replace. If the fill valve also needs replacing, add another £40 to £80.

How long does it take to replace a toilet?

A like-for-like toilet replacement takes a competent plumber two to three hours. This includes removing the old unit, inspecting the soil pipe, fitting a new wax seal and isolation valve, installing the new toilet and testing it. A back-to-wall or wall-hung toilet takes longer — typically half a day.

Can I unblock a toilet myself?

Yes, for simple blockages. A good toilet plunger clears most blockages in a few minutes. If the water is rising and not draining at all, stop flushing and call a plumber — repeated flushing can flood the bathroom. Never pour caustic drain cleaner into a toilet; it damages the seals and rarely works on the actual blockage.

What is the difference between a macerator toilet and a normal toilet?

A macerator toilet (Saniflo and similar) grinds waste and pumps it through small-bore pipework. It is used where a standard gravity-fed soil pipe cannot reach — typically basements, en-suites added to existing rooms or garage conversions. Macerators are more expensive to maintain and limited in what you can flush.

How do I know if my toilet has a hidden leak?

Put a few drops of food colouring in the cistern and wait 15 minutes without flushing. If colour appears in the bowl, you have a leaky flush valve wasting water 24/7. For floor leaks, look for staining or lifting at the base. Persistent low cistern levels overnight also point to a slow leak.

Should I buy a new toilet or get the old one repaired?

Repair if the toilet is under 10 years old and the issue is mechanical (flush valve, fill valve, seals). Replace if the pan is cracked, the ceramic is heavily stained from limescale, or you are renovating the bathroom anyway. A new close-coupled toilet supplied and fitted costs £250 to £500 — often less than multiple repair callouts to an aging unit.

Why does my toilet smell even after flushing?

Smells usually come from a dry or broken trap, a failed wax seal at the base or a vent problem on the soil stack. A plumber can diagnose by inspecting each potential source. Smells can also indicate a partial blockage downstream in the drain — a CCTV survey is worthwhile if the smell persists after sealing every joint.

Toilet Repair Services in Exmouth

Most toilet issues are diagnosed and fixed in a single visit.

Running toilet repair

Fix the most common toilet fault — a worn flush valve, faulty fill valve or stuck float that lets water trickle constantly into the bowl. Usually fixed in under an hour.

Leak repair

Diagnose and stop leaks at the cistern, the pan-to-floor seal, the fill valve, the flush valve or the supply pipe. Hidden leaks behind the unit are flagged before they cause floor damage.

Blocked toilet

Clear stubborn blockages a plunger cannot shift. Includes flexible drain rods, drain snakes and CCTV inspection if the blockage is in the soil pipe beyond the toilet.

Full toilet replacement

Remove an old toilet and fit a new close-coupled, back-to-wall or wall-hung unit. Includes new isolation valve, flexible connector, wax seal and bottom-floor sealant.

Macerator toilet repair

Saniflo, Sanicompact and other macerator-style toilets need specialist care — blocked blades, failed micro-switches and pump faults. Most plumbers in Exmouth carry common spares.

Limescale removal

Heavy limescale build-up under the rim or in the fill valve is common in hard-water areas like Exmouth. A plumber can descale internally without damaging the ceramic.

Diagnose Your Toilet Problem

Match your symptom to the most likely cause and typical fix. If in doubt, a plumber can usually diagnose over the phone.

Toilet keeps running

Likely cause: Worn flush valve washer or stuck fill valve

Typical fix: Replace the flush valve (£30 part) or adjust/replace the fill valve. A plumber will diagnose and fit in 30–60 minutes.

Toilet will not flush properly

Likely cause: Worn flush mechanism, low water level or blocked rim jets

Typical fix: Adjust the cistern water level, replace the flush handle assembly or descale the rim. Fix usually takes 30 minutes.

Water on the floor around the base

Likely cause: Failed wax seal, cracked pan or loose connection

Typical fix: Lift the toilet, replace the wax seal and refit. If the pan is cracked, you need a new toilet — leaks behind tiles can cause floor damage if ignored.

Toilet rocks slightly when you sit on it

Likely cause: Loose floor fixings or failing wax seal

Typical fix: Re-tighten floor screws and check the seal. Persistent rocking eventually breaks the wax seal and leaks — get it fixed early.

Cistern fills very slowly

Likely cause: Partially closed isolation valve, blocked inlet or low water pressure

Typical fix: Open the isolation valve fully, descale the inlet filter or check mains pressure. If the whole property has low pressure, see our low water pressure guide.

Strong smell from the toilet

Likely cause: Dry trap, broken seal or vent issue

Typical fix: A plumber can check the soil stack vent and re-seal any failed connections. Persistent smells can also indicate a partial blockage downstream.

What to Expect During a Toilet Replacement

A like-for-like toilet replacement takes a competent plumber two to three hours and follows five clear stages.

Isolate and drain

The plumber closes the isolation valve, flushes the toilet to empty the cistern and sponges out the last of the water from the bowl and cistern.

Disconnect and remove

Disconnect the cold supply, unbolt the cistern from the pan, then unbolt the pan from the floor. The old unit is carried out carefully to avoid breakage.

Inspect the soil pipe

With the toilet out, the plumber checks the soil pipe seal and the floor area underneath. This is the only time you can spot hidden leaks or rot — worth doing properly.

Fit the new toilet

New wax seal, fresh isolation valve and flexible connector, then bolt the pan to the floor and the cistern to the pan. All joints sealed with silicone where appropriate.

Test and commission

Plumber fills the cistern, runs three full flushes, checks for leaks at every joint and confirms the flow is full and the bowl refills correctly. Hand-over takes 5 minutes.
