Hi All,
I haven't been around these parts for quite some time - mostly to remove temptation! Good to be back
I have had my ECM Technika IV Profi plumbed in for the last 4 years or so using a Brita C150 under-sink kit. I apologise up-front if these guys are not site sponsors, not sure of their status:
I had it installed by a plumber. I have changed the cartridge every 12 months as per recommendation. I currently have the C150 Finest cartridge installed.
I have had a periodic problem with what appears to be air trapped in the system. This happened with the first cartridge, not with cartridges 2 and 3 and now it is doing it again with cartridge 4 i.e. the current one.
Problem scenarios:
I have had the original plumber look at this, who charged me for essentially shrugging his shoulders... I had another plumber here just the other day to fix a leak (unrelated) and he was either disinterested or had no idea.
Has anyone encountered this before and is there a way to fix this? I would greatly appreciate any guidance or insight that anyone can offer here.
Thanks
Simon

Problem scenarios:
- When the goose-neck filter tap is opened (e.g. to fill the kettle), there is up to a 20 second delay before water begins to trickle out. The pressure then steady builds.
- I actuate the ECM and there is a very audible 'grunt' that is made when the pump churns through the air. The flow is almost instant out of the group.
