If you have learned where the filling loop is and you use it every few weeks, the system is losing water. Something is getting wet.

In the Victorian terraces around the town centre, it is usually an old radiator valve or a joint behind a boxed-in pipe run. In the 1930s semis out at Warley, it is more often the expansion vessel. It has a rubber diaphragm inside that gives up somewhere around its tenth birthday.

Common Boiler Losing Pressure questions

What pressure should it be sitting at?

Cold, most boilers want somewhere around one bar. The manufacturer sticker inside the case is the one to trust, rather than a number off the internet. What matters more is whether it stays there.

Could it be the radiators rather than the boiler?

Easily. Valve glands weep slowly enough to dry on the pipe and leave nothing on the floor. They are also one of the cheapest things on a heating system to put right.

Is a small drip from the outside pipe urgent?

Not dangerous, but it will not stop on its own and it will keep costing you pressure. It points at the vessel or the relief valve. It is worth booking in rather than watching.

How long does it take to trace a loss?

Allow one to two hours for the diagnosis. Fixing a valve or recharging a vessel often follows in the same visit. A buried joint takes longer, and you are told that once it is found.

What decides the cost?

Where the water is escaping. A valve or vessel is a short job. A joint behind boxed-in pipework takes longer. The figure is for your leak, not a general rate.
