Hi all. We are new to sailing and recently purchased a 2001 C36 mkII.  As I've been going through and making repairs, I want to replace the sink drain hose and the drain line from the fridge.  I had some issues w water coming back into the fridge and read where I can raise the T fitting higher which should help that.  I was thinking the Raritan SFH1 or Trident 101 Sani Shield would be good choices for the sink drain.  Any input from you guys?  Thank you.
