Dean,
That would depend on where the Y connection is located — If it is after the
vented loop, then you should be all right. Otherwise whatever gets pumped out
of one pump will likely flow back through the other one.
If you are going to put the Y closer to the pumps, you should install check
valves so flow only goes one way. However, check the specifications on your
pumps as some do not recommend using a check valve.
All the best,
Edd

On my C&C 34, I have a non-automatic bilge pump in the well next to the mast
holder. It’s old and back flows about gallon (maybe an exaggeration!) of water
back into the bilge once it shuts off. I’m replacing it and expect I can just
attach the new bilge pump to the existing outflow piping. My question is, if I
wanted to install a second one (automatic one), slightly higher in same area,
Do I need an entirely new outflow and thru-hull or can I join it with a ‘Y’
connector to the same pipe as the first bilge pump… so they would each use same
pipe/thru-hull?
