I am a new owner of a 1994 Montgomery 15 for about 4 months now. Right now I am trying to install a home made check valve in the cockpit drain to block water trying to enter due to wave action. This also requires a pvc pipe for the centerboard rope. I have some "G/flex 650" that I think should be ok. Any ideas on how to get the two parts mounted and fully wetted by the epoxy while keeping it from dripping excessively into the CB trunk will be appreciated. I tested the valve. It seems ok. I made it from concentric polycarbonate cylinders. Also, the seal and ball are removable or replaceable from the top as instaled. The checkvalve has an ID of 0.875 inches and could accept a rubber or cork plug. There are some project photos linked below. The present plan has a smaller rope pipe fitting than shown in the view 1.
