In-pipe inserts for piping systems and related methods are described herein. An example filter insert includes an end plate having a set of openings, a set of filter tubes extending from a first side of the end plate, and a set of support rods extending through respective ones of the channels of the filter tubes. The support rods extend through the openings in the end plate. The filter insert also includes a first retainer disposed on a second side of the end plate. The first retainer is coupled to the support rods at or near first ends of the support rods. The filter insert further includes a second retainer coupled to the support rods at or near second ends of the support rods opposite the first ends such that the filter tubes are clamped between the end plate and the second retainer.
