I removed the new inline thermostat : all was tight fit, etc, so I took it and filled the "backside" with water under the tap : and its liking like crazy !
I suppose it should only get open at 88 degrees. Its not fully open, but definitely leaking quite badly !
And it's a brand new thermostat
?!
COLVERT and sewerman : thanks of the tip ! I will get a new thermostat next week
