Re: larson shower
Dino77 - The hose to the showerhead connects to a threaded fitting on top of the lav faucet unit.  There is a black plastic ringy-thingy around the threaded area.  Pull it UP to divert water to the shower, and push it down to divert water to the faucet.  This took me a whole season to figure out.  Doh!<br /><br />That's how it works on my boat, anyhow.  I have an 89 Larson San Marino 250.
