Two-Valve Tap Manifold for 4 mm Micro-Irrigation Pipe

This kit is a small manifold for the tap end of a micro-irrigation system. It screws onto a garden tap with a 3/4 or 1 inch BSP thread and divides the water into two separate lines of 4 mm pipe, each with its own on/off valve, so one outside tap can feed two watering runs that are switched independently of each other.

It is built from three kinds of part that fit one into the next. The two-way tap splitter takes the tap thread at its inlet and branches into two valved outlets. A lime quick connector clicks onto each outlet and carries a 3/4 inch BSP male thread on its other end. That thread takes a hose tail, a 3/4 inch BSP female fitting with a barbed spigot, and the 4 mm micro-irrigation pipe pushes onto the spigot.

Because each line has its own valve, one can be closed while the other keeps running: a greenhouse on one line and a raised bed on the other, or a row of patio pots and a border, each watered when it needs it. The quick connectors also let either line be unclipped from the splitter and clipped back on later without unscrewing anything at the tap.

It suits gardeners who already water with 4 mm pipe and want a second line from the same tap, as well as anyone putting together a first small micro-irrigation system. The kit contains one two-way valved tap splitter, two lime quick connectors and two 3/4 inch BSP female to 4 mm hose tails. The 4 mm pipe, drippers or sprayers and the tap itself are not included.
