Bought few months back a straight trv drayton trv4, and got around installing it last weekend, however i noticed when the trv is closed (with white cap) there was a bit of water in the head abour 1/6 of the cap i would say, when the trv head is there in frost mode, there was a bit of water seeping from the head (not from the compression fittings or radiator).
Is this normal, all my other draytons are always dry its not something i ever noticed, or do i have a faulty seal?
Thanks in advance
