All,
I have not been able to locate the waste holding tank on our boat. Can anyone tell me where exactly it would be located in the bilge and the approximate tank capacity?
Also, I was pumping out the tank last weekend to get it ready for winter haul out and I was only able to catch a prime and pump out the waste for about 5 seconds. Almost seems like its clogged. Any thoughts on what might be causing my inability to pump out the tank completely? The boat has a Vacuflush system.
Thanks in advance!

Guessing you do not have a full set of drawings supplied with your boat. Contact Sams marine with your hull number and purchase the. They will greatly assist you or whoever is working on the boat. Fantastic bit of information that some other brands do not have available. You are in good hands with a “Hat”!

Sounds like the dreaded Hatteras corroded dip tube syndrome that’s like yacht COVID-sooner or later it’s your turn in the box. Fortunately, there’s a spot on video that’ll help you out. Here’s the link: https://m.youtube.com/watch?v=k3nMZIW2dJc

Could a clog in the vent opening cause an inability to pump the tank out?

We had an issue with pump out Previous owner did not use holding but we did on trip to Keys. Had issues pumping out. Long story short we used Campo blue goo RV tank treatment. Dissolved everything that was solid and pumped right out.

1973 42c may have similar location, right in the middle between the stringers ahead of the water tank. I have a hatch in the side cabin that gives access to the top of the tank and fittings.

Re: 1981 Hatteras 43 Convertible Holding tank
I have a 79 43C. Access to mine is in the master suite next to the berth (I have one queen berth, not the twin singles). I had the same problem several years ago and had to replace the pickup tube. Its been a while, but I recall using a plastic pipe and sliding it inside the remains of the original pickup tube. I think I may have used a plumbing drain pipe with a flared end and it fit perfectly.
