A Guide to Choosing the Best Suction Pipes

A suction tube creates a vacuum and transports fluids from a source to a pump. Transporting liquids from a source to a pump requires a suction line, preferably a pipe. These pipes form an essential part of the system’s suction line in transporting liquids from a source to the pump.

Not all suction tubes will perform the same function, and sometimes it may be challenging to get the right type without professional experience. However, you don’t need to be a professional to get the right kind. This article provides guidelines for getting the right suction tube, even for a novice.


The general rule is that the diameter of the pipe should be equal to or greater than that of a suction pump. To ensure a steady liquid flow, avoid fittings at the suction pump. Position the pump inlet at the highest point, except where the liquid flows through the pipe to the channel under high pressure. Tighten the suction piping for the pump to operate correctly.

Install the isolation valve in the suction line during piping, and make it at least two pipe diameters to allow for inspection and easy maintenance. If you fix the valve in the suction in region, only use the full-flow valves. However, only close the full flow valves when the pump is off and not control the fluid flow.


The suction process requires the refluxvalves, also called check valves. These valves will come in handy when checking the flow of fluids in a reverse direction. The best place to position them is at the delivery side of the pump, and they work automatically.


Suction pipes are beneficial because you can adjust them to the desired length, most of them allowing adjustment up to 44 inches. They are suitable for one-inch inlet fluid transfer pumps. They are lightweight since they originate from PVC, compared to metallic pipes. It prevents rusting, so it prolongs their lifespan.

Most suction hose pipes work under pressure, withstanding a temperature of up to 23 °C. The operating temperature range varies, with others operating from -10°C to 55 °C. Therefore, it is doubtless to say that these pipes are very efficient and can serve you for a long time with proper maintenance.


The flexibility of suction tubes allows them to be available in different sizes, and your selection will depend on your requirements. The most common measures include pipes with internal diameters of 19 mm to 152mm, while external diameters range from 25.6mm to 172.4mm.

Small pipes are suitable for wells of 50 ft. to 100 ft., holding up to 10 gallons of water. Medium-sized lines are ideal for wells extending from 100 ft to 200 ft, whereas large pipes apply to wells over 200 ft. The storage of liquids also gives guidance on the tubes to use. Medium lines fill 40 gallons of water, while large ones fill 60 gallons.


Suction tubes are essential in maintaining the overall performance of a pumping system. To get the proper pipe, always check for the storage capacity and diameter of the line and ensure you size it well. Also, use the appropriate valves or hire a professional to do it for you if you are unsure about it. Check also about water pumps.
