Which Pump Discharge Hose Do You Need?

For a sump pump, flood pump or basement pump: Layflat hose is the standard choice. It is cheap, lightweight, easy to store on a reel, and quick to deploy. Almost every flood response van and hire fleet in the UK carries layflat as the default discharge hose.

For irrigation, drinking water, or any high pressure duty: High pressure delivery hose is the right choice. It is double layered yellow PVC, kink resistant, UV stable, abrasion resistant, and certified food and drinking water safe.

For aquariums, ponds, water features, or very light duty work: Budget discharge hose handles the job at the lowest cost. Spiral-helix reinforced thin PVC, supplied in 30 metre coils.

For pumping uphill, around corners, out of basements, or for buried installations: Discharge hose is not the right fit. You need suction and delivery hose instead, which has a nylon spiral-helix that resists kinking and crushing.

How to Size a Pump Discharge Hose

Match the hose internal diameter to your pump's discharge outlet thread. A pump with a 2" BSP outlet needs a 2" (50mm) discharge hose.

Then check working pressure. Divide your pump's maximum head (in metres) by 10 to get the equivalent pressure in bar. The hose working pressure must comfortably exceed this figure with margin to spare.

Common questions

Frequently asked questions.

What is a pump discharge hose?

A pump discharge hose is the hose that connects to the outlet of a water pump and carries the pumped water to its delivery point. Discharge is the technical term for "the water leaving the pump".


Can pump discharge hose be buried?

Layflat, and budget discharge hoses are not suitable for burial. For a permanent underground discharge run from a sump pump or packaged pump station, use suction and delivery hose, which has nylon spiral-helix reinforcement and a service life that can exceed 10-20 years buried.

What size discharge hose do I need for my pump?

Match the hose internal diameter to your pump's outlet thread size. A 1" outlet pump takes 1" (25mm) discharge hose, a 2" outlet takes 2" (50/51mm), and so on. Going smaller restricts flow.
