Do you provide 24 hour emergency plumbing?

Is it dangerous if my boiler loses pressure?

Low pressure on its own isn't dangerous. The boiler will usually lock out and stop heating rather than run unsafely. The real risk is whatever's causing it. A hidden leak can rot floorboards and stain ceilings, and a failing PRV can let hot water out. Get the cause found rather than topping up forever.

Why does my boiler pressure go up when the heating is on, then drop?

Some rise is normal, because water expands as it heats. A big jump followed by a drop usually means the expansion vessel has lost its air charge. The PRV then releases water each time the system heats up, so the pressure falls when it cools. An engineer can test and recharge or replace the vessel.

Can I leave the filling loop open?

No. A filling loop left open, even slightly, lets mains water creep into the heating system. Pressure then rises until the PRV opens, which can wear the valve out. Close both valves fully after every top-up. If your loop is the removable hose type, disconnect it as the manufacturer advises.

Will low boiler pressure stop my hot water?

On a combi boiler, usually yes. Most combis lock out completely when the pressure drops too low, so you lose hot water as well as heating. Topping up to 1 to 1.5 bar and resetting the boiler normally gets both working again, as long as there is no other fault.

How can I stop my boiler losing pressure again?

Fix the cause rather than the symptom. Have leaks repaired, get the expansion vessel checked, and have the boiler serviced once a year. A service is a good time for the engineer to check the PRV and vessel charge before they fail. Check the gauge every few weeks through the winter.

Will you provide a breakdown of costs after the job is done?

Yes, you will receive an invoice with a detailed breakdown and an engineer's report after the job.

Is there a cancellation fee if I no longer need the service?

The call-out fee applies as the cancellation fee if the engineer is on route to your property.

What should I do if I smell gas in my London flat?
