Maxi Gas Combi boiler losing pressure help required

iwantitnow

I have a Maxi combi boiler to fuel my hot water and radiators. Recently the pressure drops 0 within a couple of days. I top it up to 2 however it still drops. I have tried bleeding my radiators and can notice no leaks.

Any suggestions what to do next?

Hi

Corgi guy here.

Bleeding rads will lower the pressure.
one bar pressure when system is cold will usually suffice .
Check the rad valves for any leaks .
You might be losing water from the pressure relief valve .This should be a 15mm copper pipe from the boiler to outside .See if it is wet or has been dripping.
If you have one bar pressure and then run the heating for a while ,see how much the pressure has gone up.
Good luck.

If you have nil pressure then repressurise it and try again.
Are you losing pressure continuously when you top it up?

Since you have no idea on what to do or how to do it I suggest you call out someone who does. Only use a registered GSI.
Good Luck!

Please how do I repressurise it.

Try to locate the filling loop. Normally a flexi stainless pipe. Open the valve on it until the pressure is 1 - 1.3 bar. Keep an eye on the system to see if the pressure drops again in the future - you may have a small leak somewhere.....;)

Thanks to all for being so helpfull. I have located the refill loop.
The pressure is back up and system is up and running.
