Tuf-Tite Distribution Boxes - the US industry standard, are now available in Europe through Ashtecs. Distribution boxes are used to split effluent evenly between the outlet pipes into the percolation area. The Irish Environmental Protection Agency recommends that distribution boxes be inspected every 6 months to ensure they have not shifted. Foundations must be reset by the builder if they are found to be uneven. Ashtecs adjustable plastic weirs and distribution boxes make this instantly possible by rotating the plastic weir insert without any site interference.

D-boxes are available from many regional outlets - contact us on 0404 66433 for your nearest supplier.

Distribution box sizes are 4 hole and 7 hole.
