Hi,
After I added Fernox Leak Sealer to my sealed CH system and bled the rads and pump multiple times, every time when the pump starts there is a "water running like" noise coming from the pump for few seconds and the it disappears. Any idea how to get rid of it?
PS The pressure is set to 1.4 bars but it goes to 1.8 when the water is hot.
Thanks
