Waste tank odour

I recently purchased a 1991 Hunter 30. There is holding tank odour in the aft berth. There does not appear to be a leak, the only possible cause I have at this point is the vent from the pump out trickling waste. The aft berth is not sealed from the cockpit locker where the waste pump is located. Could this be the cause? It seems to be a small source for the smell to get down into the cabin. Is this issue common with this vintage of Hunter?

Hose Odor

Congratulations on your new boat. You will probably get many replies on this. It is probably one of the most common issues posted on this site. The archives have a WEALTH of information on this subject. You need to get familiar with the "search archives" function of the site. You will have endless reading on the topic, guaranteed. With all that said, a used boat, probably has odor permeating through the hose. If that is the case, you will need to replace it. Do not use any hose. You will see the postings on the better hose to use. There is a test that can be performed, credit to Peggy Hall. Take a rag and dampen with warm water. Put the rag around the hose. If the odor is on the rag, when removed, it is time. It is best to check in low-lying areas. Sometimes the easiest point to test is not the problem area. Odors can be tricky. Start with the most obvious. Head hoses, bilges and areas with poor air circulation. Good luck with your new purchase. I hope you enjoy immensely as we enjoy ours. Mike D

Holding Tank

Does your new boat still have the original aluminum holding tank? If so it is a disaster just waiting to happen. Since the holding tank on the H-30T (1991) is located next to the aft cabin bulkhead I suspect you have a leaking aluminum tank. I have had correspondence with a couple of 30T owners who found leaking on the bottom of their tanks where it was impossible to see the origin until the tank was removed. If you don't have a plastic holding tank let me know and I can send you pictures and instructions showing how I replaced the tank on my H-30T (1991).

Phew....

Suggest you change all the hoses to and from the holding tank as they get porous as they get older. I have a 93 Hunter 33.5 and spoke with the customer service, got the name of the mfg for the holding tank and had them send me a new one, and then did new hoses, problem solved.
