Toilet fill valve adjusted so your cistern fills to the right level and shuts off properly. No more constant running, slow filling, or wasted water.
When Your Toilet Won't Behave
You flush and the cistern takes five minutes to refill. Or worse - you hear it running constantly, trickling water into the pan all day and night.
That's your fill valve. Easy fix, saves you money on water bills.
💡 Pro tip: A constantly running toilet can waste 200+ litres a day. That's real money down the drain, especially if you're on a water meter.
Common Fill Valve Problems
| ✅ Fixable With Adjustment | ❌ Needs Parts/Replacement |
|---|---|
| Water level too high in cistern | Fill valve mechanism broken |
| Water level too low (weak flush) | Cracked overflow pipe |
| Slow filling after flush | Blocked inlet pipe (limescale) |
| Constant running/trickling | Worn flush valve (different job) |
Most cistern issues are fixable without replacing anything.

What It Costs
Our minimum callout: £60 (covers first hour).
Adjusting a fill valve takes 15-20 minutes, so you'll pay £60. While I'm there we can tackle other bathroom jobs - tighten toilet seat, replace tap washers, fix shower head.
💡 Multiple toilets? If you've got two bathrooms both playing up, we'll sort them both in one visit.
Perfect For You If...
✅ Slow filling - cistern takes ages after flushing
✅ Constant running - hear water trickling all the time
✅ Wrong water level - too full (overflow risk) or too low (weak flush)
✅ High water bill - meter reading gone up for no reason

What to Expect
Step 1: Diagnose The Problem
I lift the cistern lid and have a look at how the fill valve's behaving. Usually obvious what's wrong - float stuck, water level set wrong, or valve not shutting off.
Step 2: Adjust & Test
Adjust the float arm or screw to set the correct water level (about 2-3cm below overflow pipe). If there's limescale or debris, clean it off. Test flush a few times.
Step 3: Final Check
Make sure it fills properly, shuts off cleanly, and doesn't run on. You should hear silence once the cistern's full.
🔧 DIY Tips
Adjusting your own toilet fill valve is doable:
🔧 What you'll need
- Screwdriver (maybe)
- Adjustable spanner (maybe)
- Torch to see inside the cistern
- Cloth for mopping up drips
🎯 For older brass ballcock valves
- Find the float arm (brass arm with ball on the end)
- Bend it DOWN slightly to reduce water level (ball sits lower)
- Bend it UP slightly to increase water level (ball sits higher)
- Flush and check the new level
- Aim for 2-3cm below the overflow pipe
📱 For modern plastic fill valves
- Look for an adjustment screw or clip on the side
- Turn screw clockwise to lower water level
- Turn anti-clockwise to raise water level
- Some have a sliding clip you move up/down
- Flush and test
⚠️ Common DIY mistakes
- Setting water level too low (weak flush)
- Setting too high (wastes water, might overflow)
- Not checking it actually shuts off after filling
- Bending old brass arms too hard (they snap)
💡 Pro trick: While you've got the lid off, check for limescale buildup around the fill valve. A quick wipe with vinegar on a cloth can improve performance massively.
Rather leave it to a pro? No problem - that's what I'm here for. Give me a call.
Good to Know
🎨 While I'm there: If your toilet has other niggles (wobbly seat, stiff handle, slow drain), mention them. Can often fix multiple issues in the same visit.
When adjustment isn't enough: If the fill valve mechanism itself is worn out, adjustment won't help - it needs replacing. I'll let you know if that's the case. Replacement is a bigger job (30-45 mins) but still straightforward.
Limescale issues: Exeter water is pretty hard. If you've got major limescale buildup in your cistern, that might be causing the valve to stick. Sometimes cleaning is all it needs, sometimes replacement is better.
Frequently Asked Questions
How do I know if my toilet fill valve needs adjusting?
Common signs: toilet takes ages to fill after flushing, water keeps running into the pan constantly, you hear it filling randomly when nobody's used it, or the water level in the cistern is too high/low. All fixable with adjustment.
Will adjusting it stop my toilet running constantly?
Usually yes - if water's constantly trickling into the pan, it's often because the fill valve isn't shutting off properly. Adjusting the float level or replacing a worn washer sorts it. If the flush valve itself is worn, that's a different job.
Can you do this while I'm at work?
Yes, as long as I can access the bathroom. The water will be off briefly while I work on it (few minutes), but everything will be working and tested before I leave. Just let me know if anyone's home who needs to use the toilet.
Is this the same as fixing a leaky toilet?
Related but different. Fill valve adjustment stops constant filling or slow filling. A leaky toilet usually means the flush valve (the bit that lets water into the pan) is worn. I can diagnose which problem you've got when I look at it.
Will it waste less water after adjusting?
Yes - if your toilet's been constantly running or overfilling, you've been wasting water (and money) 24/7. Adjusting the fill valve stops that. Can save surprisingly high amounts on your water bill.
