Re: Drains, valves, and seacocks: weighing the alternatives

If you do decide to add the ball valves, be advised that most valves will be NPT thread (ie tapered) and the through hull threads are not. What that means is that when you install the valves on the through hull threads you'll only get maybe 1 1/2 threads engaged before it tightens up.. not very secure. Check Mainesail's 'how-to' site for the RIGHT way to do this.
