With this lead through set a quick water connection to an ebb and flow tray can be realized. The lead through is inserted through the hole in the discharge point in the ebb & flow tray and secured with the nut.
The tap is then turned onto the lead through. This allows the amount of water that is pumped into the tray to be adjusted.
At the other end of the tap 25mm PVC fittings can be turned for the water supply line.
