What is the minimum tube size for low flow sampling?

If the case is the well casing diameter, typical sizes are 50 mm (2-inch US pipe) and 100 mm (4-inch US pipe) flush-threaded pipe. However, over the past decade, small diameter wells installed using direct- push rigs have become more common, using 16 mm (0.5-inch US pipe) and 38 mm (0.75-inch US pipe) casings.

QED manufactures bladder pumps to fit well casings 0.75-inch diameter and larger. You can find more information about these pumps on our website at www.qedenv.com.
