Installation kit for our 10" GAC/Phos filter cartridge and housing, consisting of 5 metres of JG 3/8th or 10mm drinking line and a push fit isolating tee with built in non-return-valve.
Simply isolate the cold supply, cut the 15mm supply pipe (using a rotary pipe slice) and push-fit this tee into place. You then have a cold water supply to your drinking water filter and faucet.
