Mend Worcester 440 Heating Boiler Radiators

Worcester combi 440 boiler?

I got an 18 month boiler which was working ok till few month ago. I noticed that the pressure is dropping and it requires frequent filling (once a month). It is getting a bit rusty from inside. It still works even if I switch off the central heating and hot water buttons from the timer!!

I also need to bleed the some of the radiators.

The whole system is nearly 18 month old including the pipes.

Obviously there is a water leak somewhere,first check the PRV pipe which should terminate outside just below the flue.If it`s leaking you need a new PRV.
Signs of rust inside suggest it may be something else,so I suggest getting a Corgi Engeneer in or your installer back to give it a thorough check.
