If you think the strainer coming apart is bad...wait till you twist the old style seacock where the top bolts on and it starts to fall apart on you...
...Especially with no way to stop the water flow if the top breaks off completely!!!!
Of course that was back in July so the fleet mechanic and I just used 2 "t" bolt clamps to keep it together for the rest of the season.
Running commercial boats is a good exercise in seeing how really silly many "ABYC" guidelines are and how many rec boaters really fret over nothing.
Sure there a great way of doing things and products supporting those theories....an I strive to do the best whenever I can for my boat...but falling way short doesn't mean your boat is going to sink without a doubt or catch fire or any other unimaginable catastrophe...especially if you are aboard a lot and can catch things as they progressively get worse.
