"If any L450 or L450S owners have some location ideas that would be great!"
I installed my 180 lt/hr kit in the starboard hull
of my L450 owners version.
Membranes mounted for/aft under floor directly below electrical
pump / high pressure pump and filters under floor around the starboard bilge
area. Intake thru hull
installed here as well.
in cupboard under starboard head holding tank
Test point plumbed to spigot over owners vanity basin. Discharge installed next to vanity basin discharge in outside of starboard hull
Freshwater output is only feed to starboard tank.
I installed a ball valve from house fresh water
pipe to the port tank in port hull.
This enables me to transfer from starboard to port as required, saving a change over valve and hose run across the boat starboard to port from the water
