Welcome to our forum.
I dont know about the O ring. My dealer never called me today, so I guess we'll see what info I get on Monday, and see what happens between now and then. Thanks!
Anne-PM me if you have any questions. Check your water level and see if it lost any more. The union (white ring you tightend) can infact loosen. It looks like that was pump 1 which does the filtering/heating.
Thank you all!At 7 am when I left today, all was well- previous water dried up, and no dripping, pumps on or off, and no change in water level. What the h%@^ is a sclice valve?
