Pool plumbing: pipes, fittings, and valves

Find the parts you need to connect, repair, or modify your pool plumbing: rigid PVC pipes, flexible hoses, fittings, unions, valves, gaskets, and assembly products. Compare the nominal diameter, connection type, and equipment part number to choose the right parts.

Choose the pipe and the right connection

• Schedule 40 rigid PVC pipe: available in several diameters, sold by the foot, with a maximum length of 10 ft per piece. We recommend picking up this pipe at a store.
• White 1½ in. SpaFlex and white 2 in. SpaFlex: flexible hoses sold by the foot, to be joined with compatible solvent cement.
• 1⅝ in. Tigerflex: hose sold by the foot for use with compatible barbed fittings. Its connection method differs from that of SpaFlex, which is solvent-welded.

Valves, unions, and repair parts

A diverter valve directs water between pipes; a ball valve or gate valve is used to isolate a compatible section; a check valve limits reverse flow. Unions provide a convenient disconnect point for maintenance. When choosing a replacement part, also check the thread and gasket seat: two fittings with the same nominal size are not necessarily interchangeable.

Prepare the assembly

Choose the cement and primer based on the pipe material and the manufacturer’s instructions. A socket fitting, a barbed fitting, and a threaded fitting do not use the same sealing method. Make sure you have the necessary gaskets, clamps, or assembly products, and allow the recommended curing time before turning the water back on.
