Installing layflat and flat PE submains

  • The submains should be installed in a shallow trench. This helps keep the hose moving away from the laterals, which causes laterals to pop-off.

    The trench should be the width of the layflat (e.g. 4” wide for 4” layflat) and ½ the diameter for the depth (e.g. 2” for 4” layflat).

  • When installing, pull it tight every 15 m (50 ft) or so to eliminate kinks and snaking.


  • Never drag the hose.

  • A note for seasonal layflat retrieval – in most cases, the core diameter when retrieving must be above 100 mm (4”).
