Lisa, Have you checked your original posting for the responses to your question? Here is a copy of the response I posted to your original question:Check under the V-berth, on some of the older C22's there are 2 thruhulls that were for the old style direct discharge marine head. When I purchased my 1973 C22 # 1909, 9 years ago it still had the head in it. The first thing I did was replace it with a porta potti, and capped off the intake and discharge thruhulls. If you have the remnants of these thruhulls and they leak the water would come out through one of two holes near the floor on the front bulkhead of the V-berth. If the leak is on the upper end of the pipe and valve to these thruhulls which is located above the waterline It will only leak while underway.Barry Broyles C22 # 1909 "Brighteyes"
