FloPlast Underground Square Grid Hopper 110mm

A 110mm Square Grid Hopper is the top half of a traditional trapped gully, for plumbers and groundworkers who need an open collecting head for downpipes, waste pipes and run-off from paving.

It fits over a 110mm gully trap and gives you a square grid that lifts out for cleaning and rodding the trap below. The D504 code on our listing matches FloPlast’s square hopper, which is used with their low back P trap and universal gully trap. One hopper can take several waste pipes, and the grid can be cut to let them through.

Run incoming waste pipes down through the grid so they finish below grid level, which stops splashing and keeps leaves out of the pipe ends. Make sure the hopper sits level and is well bedded so it can’t rock, and check how the hopper is to be joined to the trap before you start.

A 110mm single socket low back P trap and the rest of the gully parts are in our soil and underground pipe and fittings range, ready to pair with the 110mm Square Grid Hopper.

Common Questions

Does the hopper include the grid? Yes, it comes with its square grid, which lifts out so the trap below can be cleared.

What trap does it fit? A 110mm gully trap such as a low back P trap. Check the trap and hopper are from a matching system before you buy.

Can several pipes go into one hopper? Yes. Cut the grid to let the pipes through and finish each pipe below the grid so it discharges cleanly into the trap.

How should the pipe be bedded? Lay it on a granular bed, such as pea gravel, with a steady fall, and surround it in the same material before backfilling. Keep big stones and rubble away from the pipe and fittings.
