No and no need for one here. Our boat has a wye fitting, not a valve, which allows the skipper to discharge overboard or through the deck pump out fitting without fussing with a valve. Our tank has a discharge stand pipe. That pipe has a hose to a wye fitting; one routes to an overboard macerator pump the other to the deck pump out. Simple, effective and convenient.i have my hunter 456 in the Caribbean. Has anyone put a y valve in to pump overboard?

Hunter built our boat as is with the wye fitting, two electric macerator pump toilets and an electric macerator overboard pump.Did you install the pump out with the y fitting or was it already in place.
