It would be quite a job to relocate the raw water pump on my Yanmar
much lower

I thought about running a line from after the pump over to the
Aqualarm and back for just the reasons you cite but am reluctant to
change a silver painted factory hose. No practical reason not to but
it's the kind of thing that could be a hang up and haggling point with
an unimaginitive insurance surveyor down the road.
