Peggy,
I am re-plumbing my holding tank to include a macerator pump, Y-valve,
and through hull. The easiest way to mount the macerator pump is to
screw it into the outlet of the tank then plumb to the y-valve. Question
is, will the pump out be able to suck through the pump or can I turn the
pump on while pumping out the tank. Also is there any problem with
pushing stuff through the Y-valve rather than pulling through the valve.
Thanks
