Hi. I have a Vaillant Eco Tec Boiler we have just moved into the house and it looks like it was installed in 2007 - we’ve just had it serviced about 2 months ago and it’s now leaking and needing topped up every other day.
Nothing on the radiators but the discharge pipe under the boiler I attached a bag to that last night and this morning had water in it. How do we fix?
