Suction Hose

Suction & Delivery Hose is the heavy hitter of the hose family: rigid but flexible, shock resistant, and built around an embedded nylon spiral-helix that stops the hose collapsing under suction or kinking under sharp bends. Available...

Key Benefits

  • Resistant to kinking: nylon spiral-helix reinforcement holds shape around tight bends
  • Flexible: rigid wall, but coils and lays out easily
  • Can be buried: built to survive permanent underground installation
  • Ideal for pumping upwards: holds shape when running up stairs, out of basements, or over walls
  • Hardwearing: shock resistant PVC stands up to construction sites, hire fleet use, and abrasion
  • Dual purpose: works on both the suction (inlet) side and the delivery (outlet) side of pumps

When to Choose Suction & Delivery Hose Over Layflat

The decision usually comes down to the route the water has to travel. If your hose run is straight, level, and on open ground, Layflat Hose is cheaper and easier to store. If the run involves any of the following, suction and delivery hose is the right choice:

  • Pumping out of a basement, cellar, or lift shaft (water travels upwards)
  • Running over steps, kerbs, or uneven ground
  • Sharp corners or 90 degree turns
  • Permanent or semi-permanent installations
  • Buried hose runs, for example from a packaged pump station to a discharge point under block paving
  • Anywhere the hose may be driven over, walked on, or knocked


It is also the standard choice for the suction side of a surface mounted pump. A surface pump pulls water up through its inlet by creating a vacuum, and the hose used must hold its shape under that suction load. Layflat hose will collapse flat and block flow, so where flexible hose is needed on the suction side, only a rigid walled hose with spiral reinforcement will do the job.

Permanently installed rigid pipework is the alternative where a fixed installation suits the application.

How to Choose the Right Size

Match the hose internal diameter to your pump's port size. A pump with a 2" suction inlet needs 2" (51mm) suction hose. Going smaller restricts flow, drops your pumping rate, and on the suction side can cause cavitation that damages the pump.

Typical Applications

  • Surface mounted pump suction lines drawing from tanks, ponds, sumps, or rainwater harvesting systems
  • Permanent discharge runs from packaged pump stations and basement sump systems
  • Site dewatering on construction projects where hoses are exposed to traffic and abrasion
  • Agricultural irrigation feeds where hoses run across fields and are repositioned regularly
  • Flood response work where pumps need to lift water up and out of cellars and basements
  • Hire fleet use, where durability and resistance to mishandling matter

Common questions

Frequently asked questions.

Will suction and delivery hose kink?

The nylon spiral-helix reinforcement is specifically designed to prevent kinking. It will hold its bore around corners, over steps, and around tight bends where layflat hose would fold and cut off flow. It is not indestructible, so avoid sharp bends tighter than the hose's stated minimum bend radius.

Can I use suction and delivery hose on a submersible pump?

Yes, on the delivery side. Submersible pumps push water upwards from below, and suction delivery hose handles the lift comfortably. It is the better choice over layflat where the hose has to climb out of a deep sump or borehole, or where the discharge run involves bends.
