Our boiler is nearly 3 years old and has recently had an annual service and passed fine. We have heating and hot water without problem but for the past few weeks we are having to top up the pressure once or twice daily to keep it above 0.6. From reading other posts am I right in assuming we are likely to have a leak somewhere? The whole central heating system and piping was newly put in 3 years ago, no copper pipes, all 'plastic' tubing. I am worried that we have under floor piping in the lounge which is under laminate as I think we might have a pipe connectionj under there? What option do we have before taking the floor up?
Thanks
