Just an update on this old post.
Never have found the problem but now I have a clue.
Since it has been so Very Very hot the last couple of months the problem has gone away (temporarily I’m sure).
Now I’m wondering:
- bottom of tank had accumulated water and now its remixed and gone?
- regulator working better in hot weather?
- brain fried in hot weather and im inaginin tings?
Just wondering.
