Capping off bulkhead hole

[Vancouver Reefer]

Bulkhead with a plug in it is the safest, easiest and quickest to do.

Place bulkhead with threads protruding into the tank, make sure you get a bulkhead with threads on the inside:



Place teflon tape around the threads on the plug and then screw the plug into the bulkhead:



Hope this helps.

I got a free scrap piece of 1/4" acrylic, cut it to size and siliconed it over a hole on the back of my tank. I went with acrylic instead of glass because it is simple to cut to size yourself. If the hole is at the bottom of an overflow I would go with Vancouver Reefer and use a bulkhead and plug because unless there is enough room to slip a blade in afterward it won't be coming off again easily.

I've done similar thing in the past - positioning the bulkhead with threads protruding outside of the tank and using slip on plug, not threaded one. If I just do what you suggest, what end I put the gasket on then? Per manufacturer instructions it should be be outside the tank, since it shouldn't be placed on the side where bulkhead nut is. Am I correct?
