Re: Location of water tank breather pipe
I agree with MedSailor: he doesn't understand the contamination issue. Unless you don't care about bilge fumes affecting your drinking water, I wouldn't extend the vent hose to the bilge. BTW, as you drain your tank, you may be creating a partial vacuum in the vent line, then what do you think might happen (presumably the loop itself isn't vented)?
