A test assembly for permitting the sampling of the effluent of a waste water treatment apparatus is comprised of at least two parallel testing lines, one testing line being in flow communication with effluent that has been filtered through one type of filter and the second testing line being in flow communication with effluent that is unfiltered or has been filtered through a second type of filter. At least one positive shut-off valve is provided so each testing line can be shut off when effluent is passing through the other testing line.
