I have a 2007 Autotrail Cheyenne and when I run the shower the water temperature goes up and down. It is a straight mixer (photo attached) which I have had to pieces and cannot see any problems. Both the vanity and kitchen sink work ok and the problem occurs even when no other taps are being run.
Can anybody suggest a possible cause. Cheers. Dave
