Boiler pressure topped up to correct level so your heating works again. I'll show you how to do it yourself next time.

No Heating, No Hot Water, No Idea Why

The boiler's not firing. No heating. No hot water. You check the boiler - there's a gauge with a needle pointing to zero. Someone mentioned "boiler pressure" but you've no idea how to fix it.

Nine times out of ten, topping up the pressure solves it. Takes 2 minutes. But only if you know where the filling loop is and how to use it.

💡 Pro tip: Boiler pressure drops are usually harmless - the system just needs topping up. If it keeps happening, that's when you worry about leaks. But a one-off top-up? Totally normal.


Why Pressure Drops

Common Causes:

  • Radiators bled recently (removes water from system)
  • Small leak somewhere (radiator valve, pipe joint)
  • Pressure relief valve vented (if system was over-filled before)
  • Just time and natural evaporation

What to Expect

Step 1: Assess

Check current pressure, confirm that's why boiler's not firing.

Step 2: Top Up

Use filling loop to restore pressure to correct level (1.2 bar).

Step 3: Demonstrate

Show you exactly which valves to turn, how much to turn them, when to stop.

🔧 DIY Tips

Once you know how, this is a 2-minute job:

🔧 Finding the filling loop Usually under the boiler. Looks like a braided flexible hose connecting two pipes, with a valve at each end.

📐 The process

  1. Check pressure gauge (should be below 1.0 if you need to fill)
  2. Turn both filling loop valves slowly anti-clockwise
  3. You'll hear water flowing into the system
  4. Watch pressure gauge - stop at 1.2 bar (in the green zone)
  5. Turn both valves fully OFF (clockwise)
  6. Check gauge stabilizes at 1.0-1.5 bar

⚠️ Common mistakes

  • Over-filling (above 2.0 bar) - pressure relief will vent
  • Leaving one valve open - pressure keeps rising
  • Turning valves too fast - overshoots target pressure
  • Forgetting to close valves - water everywhere

💡 Pro trick: Only do this when system's cold. If you've just had heating on, wait 30 mins for pressure to stabilize before topping up.

Rather leave it to a pro? No problem - that's what I'm here for. Give me a call.

Good to Know

🎨 Persistent drops: If you're topping up more than once every few months, get a heating engineer to find the leak. Don't keep filling it indefinitely - you're wasting water and there's a problem that needs fixing.

Old vs new boilers: Modern combis usually have external filling loops under the boiler. Some older models have internal filling loops accessed via a key. I can show you whichever type yours is.

Exeter's hard water: Limescale can cause small leaks in older systems. If your boiler's 10+ years old and losing pressure, might be time for a service to check everything's healthy.

Frequently Asked Questions

How do you top up boiler pressure?

Using the filling loop - it's usually under the boiler, a braided hose with a valve at each end. Open both valves slowly, watch the pressure gauge rise to 1.2 bar, then close both valves. Simple once you know where it is.

Will you show me how to do it myself?

Absolutely - that's half the point. Once I've done it and shown you, you'll be able to top it up yourself if it drops again. Takes 2 minutes once you know how.

What if the pressure keeps dropping after you top it up?

That means there's a leak somewhere in the system. I'll check obvious places (radiator valves, visible pipes), but persistent pressure drops need a Gas Safe heating engineer to find and fix the leak properly.

Is it safe to top up boiler pressure yourself?

Yes - you're just adding water to a sealed system. The only risk is over-filling (which makes the pressure relief valve vent water), but that's not dangerous, just messy.

How often should I need to top up pressure?

If your system's healthy: almost never. Maybe once a year after bleeding radiators. If you're topping up more than once a month, there's a leak that needs finding.
