I have to disagree with the use of those bulkhead fittings....they are VERY brittle and can snap easily...Trust me I went through 6 before using Rex's Idea.
I have been using your idea without the sealant for a couple weeks now and it works GREAT! I would have never thought of that til you mentioned it! Thanks again HIGHLY RECOMMENDED!
