NO the end of the line drains are overkill definatly...........we never have used them, nor ever will and 2 out of 10 contractors use them.......the small compressor is fine, except if you have over 180 foot runs, where i suggest you install another tee to blow out. becasue its too long for a small compressor..............honestly i wouldnt use them
