Boiler Losing Pressure for Kingston upon Thames homes
A sealed heating system should hold its pressure for months. If you are re-pressurising every week, water is leaving the system or the expansion vessel is no longer absorbing expansion.
The common causes are a weeping radiator valve or towel rail, a pinhole in buried pipework, a leaking auto air vent, a failed pressure relief valve discharging outside, or a flat expansion vessel with a perished diaphragm.
When your boiler dies on a Sunday morning or a pipe bursts under the kitchen sink, the last thing you want is a national callout line dispatching whoever's "nearest" — sometimes an hour away. Maxfix Plumbing and Heating is based in Kingston upon Thames.

Frequently asked
Your questions, answered
What pressure should my boiler be at?
Most domestic systems sit around 1 to 1.5 bar cold, rising when hot. Check the manufacturer figure on your appliance — some differ.
Is it safe to keep topping up?
Short term yes, but repeatedly adding fresh water introduces oxygen and accelerates internal corrosion and sludge. It is worth fixing the cause.
How do you find a hidden leak?
Pressure testing, thermal imaging and acoustic tracing where needed, so we open up one small area rather than a whole floor.
Could it be the expansion vessel?
Very often, especially if the pressure swings widely between cold and hot. We test the charge and recharge or replace it.
