Dear Sir or Madame,

I have a 1987 Hunter 28.5 sailboat with a waste holding tank and a manual pump-out system that has a diaphragm hand pump. Attached are two photos of the diaphragm hand pump. The black coloured diaphragm is 5 inches in diameter and has a hole in it. Can I replace the black coloured diaphragm or the entire hand pump?
Thanks. Billy

You only need to replace the diaphragm, but not with just any black diaphragm that looks right... it needs to be one for the same model from the pump mfr to be sure it's exactly the right size and any other details that matter.

Hello Peggie,

Thank you for your response to my inquiry. The hand pump is a Rule model. I bought this boat last Spring, so I am not sure whether it is the original pump with the 1987 Hunter 28.5 or not. I have been looking for a part and will continue. Billy

Have had my share of those pumps, after a while the plastic handle tends to snap off. I would say replace the whole thing and do the job just once hopefully for the time you keep the boat.

is there a use for manual pumpouts anymore? Where does it go? Overboard dumping is no longer allowed, so I removed all the manual hoses, etc. and sealed the thruhull. Now just have a pumpout.

In Canada, there are few pump out places and overboard is legal.

Helllo Peggie,

Do you know where I can buy a replacement diaphragm for this hand pump? Billy

Hello,

You can pump-out in the Atlantic Ocean. Billy
