Hi all hope we all had a great '91 season - I did!
Anyway,
After living the jammed macerator pump ordeal, and you know what you
have to do to replace the pump and clear the effluent (sp?), I
installed a Y valve.
Basically one end of the fork goes to the macerator pump and then to
a through hull fitting. The other side of the fork goes to a side pump
out port (the boat came out of Lake Winnipesauke). Of course the lower half
of the Y connects to the holding tank.
Quick diagram: /-----------> to side pump out port

\ macerator-----------> to thru hull fitting
The reason I did this is because if the macerator gets jammed again,
I can pump out the tank from any pumping station and then work on
removing the pump (not fun!). Problem is when I turn the Y to use the
macerator, the flow from the tank is barely a dribble. It takes a LONG
time to empty the tank, whereas before, when hooked directly to the
holding tank, the stuff would 'shoot' out the side.
Anybody else have the above configuration or run into this situation
before?

Thanks

Wild guess dept:
The Y valve is not air tight on the upper leg, which causes the
macerator pump to cavitate?

your sucking air from someplace, its easier for the pump to
pull air (least resistance). put a bronze gate valve on
the line that does NOT go to the macerator, and after the y.
this should close off the other line for sure.
if the y is the only change you made, the above has to work.
you can test this out before you put in a valve, disconnect
the y from the line, put your hand over the end of the y
valve, turn on the macerator and see what happens...

| 927.3 | Check the seal on the Y Valve (oh yuck) | FSOA::MCKIE | Sun Nov 10 1991 09:44 | 14 | |
Joe,
It is possible that the Y valve is not seating well when you
have it cover up the pump-out side. Hence the recommendation
in .2. Although totally "yucky", you can put a new coat of
lubricant on the seal after checking it.
Is your pump still in the same position relative to the tank
as it was before you installed all this good stuff?
I did the same project this summer...
