> Why are check valves a no-no?
I'm not real sure, but I assume that a bilge pump being a VERY important
system, a check valve puts a restriction in the output of the pump. At best,
it restricts the flow, at worst, it could clog and shut the flow off
completely.
That being said, by main bilge pump DOES have a check valve and looks like
it has had since the boat was new (1988 model boat). It has never been a
problem. I do have an emergency backup pump, a 3700 gph pump mounted about 3
inches above the main pump, so I haven't worried about the main pump
failing. Actually it has failed once a couple of years ago, but that was a
switch as I remember and had nothing to do with this check valve. I do think
it's important to have either a check valve or a vented loop in the
discharge of a bilge pump. My big pump has the vented loop.
I included the "check valve no-no" comment in my original note because I
knew if I didn't someone would probably point out to me what a dumb-a$$ I
was for using them......... :o)
