My combi boiler keeps loosing pressure & the overflow is dripping

[GreenSS]

As the title says, sometimes my boiler turns it self off when it goes to zero pressure which happens quite a lot so I re- pressurise & comes back on all fine (heating & hot water). When the heating or hot water is on, small drops of water comes out of the overflow.

Also when I have restarted the boiler & the heating is on for awhile I'll go in the loft & the boiler has turned itself off with zero pressure but still overflowing.

It sometimes drips from the bottom of the boiler when heating is on.

Lastly I have bleed all the rads in the house.

I'm wondering if it's the pump?

Feedback would be appreciated

No not the pump I would say you have a leak somewhere on your system that's why the pressure is dropping

Do you know the make and model of your boiler ?

Well the overflow is dripping & I can't see where the water is dripping from within the boiler

Any chance of a pic of the pipe that's dripping?

Ahhh man wish I could but I'm at work till tomorrow. As soon as I get home I'll take a picture for you. You got an idea roughly why it could be leaking pressure? My boiler was loosing pressure before it started leaking from the bottom

Depends where it's coming from tbh the easiest way would be to call a gas safe engy on Monday

That's the annoying thing I have done but made it worse because after he fiddled about, boiler now goes to zero & leaks from the bottom which it didn't do before he came
