Why won't the toilet stop running?
Picture it: 2 a.m., you’ve just flushed, and instead of a polite refill you’re treated to a never-ending hiss that’s louder than the night bus on Oxford Street.
Besides the irritation, a running toilet can waste up to 200 litres a day, the same as 2,600 cups of tea. Bad for the planet, worse for metered water bills.
Our engineers’ secret? A grab-bag of four mission-critical parts that cover 90 % of toilet call-outs.
1. Universal Fill Valve
Symptom: Water trickles into the pan long after the flush.
Why it fails: Limescale (cheers, Thames Water) or worn-out seals.
Our fix: We carry a quiet-fill, side- or bottom-entry valve that adjusts to pretty much any cistern height. Swaps out in 20 minutes, no special tools—meaning your marble floor stays pristine.
Premium perk: Our valves have rubber seals rated for hard-water zones, so you won’t be back on the blower in six months.
2. Silicone Flapper/Flush Seal
Symptom: Ghost flushing—cistern empties itself every few minutes.
Why it fails: Brittle rubber or a chain that’s too tight.
Our fix: A chemical-resistant silicone flapper that copes with those blue toilet tabs interior designers love. We also trim the chain to the Goldilocks length (not too slack, not too tight).
Pro tip: If you hear a brief glug every 10 min, shine a torch into the cistern. If the water level wiggles, the flapper’s gone on holiday.
3. Adjustable Float/Fill Cup
Symptom: Water line creeps up and cascades into the overflow tube.
Why it fails: Older ballcocks get waterlogged or stick on limescale.
Our fix: A compact float cup that slides along the valve stem. It fits slimline designer cisterns the old ball-on-a-stick can’t. We dial in the level so it shuts off bang on the fill mark saving you cash and the sound of Niagara.
4. Dual-Flush Button Kit
Symptom: Push button sticks half-down; cistern never reseals.
Why it fails: Plastic threads strip, spindle gums up, or the return spring snaps.
Our fix: We stock a chrome-or-matt-black button kit (to match your taps, naturally) with a stainless spring. Swaps into most concealed frames without ripping off expensive tiled boxing.
Why DIY Isn’t Always Cheaper
Yes, you can order a £12 fill valve online. But factor in:
- Half a Saturday lost to YouTube rabbit holes.
- £80 of tools you’ll allegedly “use again”.
- The risk of shearing a shut-off valve that’s older than the Gherkin and flooding the downstairs neighbour.
Our call-outs start at £120 plus VAT and we hit any Zone 1–2 postcode in under 60 minutes; Islington, Camden, Mayfair, you name it. For penthouses and heritage homes, we carry indemnity insurance that covers seven-figure refurbishments. Peace of mind, priced sensibly.
