New unvented system - ground floor losing pressure

[plastics77]

Which model Ecofit Pure (Since its not an Ecotec) do you have? Does the model number start with 4 or 6. There is a badge on the underside?

Hi there, it's an Ecofit pure 630

Yup plumber not coming and insists not a boiler issue, says it's a leak that needs sorting. He said just keep filling up and resetting boiler until leak sorted. Good point re. Electric immersion heater, I'm not sure where that switch is on this new system, will have to ask.


What's an auto bypass??

follow the cable to hopefully find a switch for the immersion

An auto bypass will open to give water somewhere to go if the pump is running but zone valves are shut.
Nothing to do with your leak problem

All Vaillant System boilers have an auto bypass integrated so doesn't need an external one.
