How to Install an Under Counter Water Filter System

Step-by-Step Guide

1. 1

   Step 1: Look under your kitchen sink and identify the cold water pipe feeding your cold tap.

   If you have a monoblock style tap with flexible hoses where it is difficult to determine which pipe is the cold main, run the hot tap for a couple of minutes, and you should clearly be able to see which is the warm pipe and which is the cold by touching the copper pipes.
2. 2

   Step 2: Ensure the section of copper pipe is suitable for installation of the saddle valve clamping device.

   This means check it is clean, free from corrosion or any nearby obstructions. ,,,,,,,,,,, Threaded cartridges will screw into the head in an anti-clockwise direction. ,,, For a standard touch tap (i.e. as shown in the image) you will require a 12mm hole. ,,,, Tighten up fully so the tap above the worktop no longer moves. , Line up the tube with the red collet and push it home. , Line up the tube with the blue collect and push it home. ,,,, This is to prime/flush the new cartridge. ,,

   Step 3: Remove the saddle valve from the packaging - This is the device which looks like a small clamp

4. 4

   Step 4: with tubing attached to it.

5. 5

   Step 5: Identify the diameter of the pipework - for a UK installation this will be 15mm or 22mm.

6. 6

   Step 6: Set the small mounting block from the clamp on the pipe - the side you use will be determined by the diameter of the pipe.

7. 7

   Step 7: Fit the clamp over the pipe and mounting block

8. 8

   Step 8: and tighten the nut at the base (turn anti clock-wise).

9. 9

   Step 9: Take a bucket or similar receptacle

10. 10

    Step 10: and place the red end of the tube into it.

11. 11

    Step 11: Turn the T-Bar handle on the top of the clamp clockwise fully down - this will pierce the copper pipe.

12. 12

    Step 12: Remove the filter housing

13. 13

    Step 13: housing bracket and screws from the packaging

14. 14

    Step 14: Screw the bracket to a suitable part of the kitchen cabinet

15. 15

    Step 15: you will need to check the dimensions of the housing to ensure it will mount.

16. 16

    Step 16: Open the filter cartridge supplied with the system

17. 17

    Step 17: Unscrew the filter cartridge housing

18. 18

    Step 18: Install the cartridge into the housing - cartridges are usually threaded or flat seal - flat seal cartridges simply sit in the housing and when its tightened up form the connections necessary.

19. 19

    Step 19: Re-assemble the filter housing.

20. 20

    Step 20: Mount the filter housing on the bracket

21. 21

    Step 21: Drill a suitable hole in the worktop or kitchen sink for the drinking water faucet/tap.

22. 22

    Step 22: Seat the tap base over the hole - this neatens up installation

23. 23

    Step 23: Push the tap tubing through the hole (from the top side of the hole)

24. 24

    Step 24: and mount the tap into its desired position.

25. 25

    Step 25: Fit the tap washer over the tubing beneath the sink

26. 26

    Step 26: and push up to the worktop/sink base

27. 27

    Step 27: Fit the tap nut over the tubing and turn anti-clockwise.

28. 28

    Step 28: Connect the red tube you have in the bucket to the input side of the filter housing - these are simple push fit connectors.

29. 29

    Step 29: Connect the blue tube from the tap to the output side of the filter housing - these are simple push fit connectors.

30. 30

    Step 30: Carefully turn the T-Bar on the saddle valve anti-clockwise - this will allow water to flow through the red tube

31. 31

    Step 31: to the filter housing

32. 32

    Step 32: and on to the tap.

33. 33

    Step 33: Check for leaks - if leaks are found see the tips section

34. 34

    Step 34: Wait two minutes

35. 35

    Step 35: Turn on the drinking water tap

36. 36

    Step 36: and allow the water to flow for two minutes.

37. 37

    Step 37: Adjust the saddle valve to ensure optimum flow to 1.5 liters (0.4 US gal) per minute - turn clockwise to reduce the flow

38. 38

    Step 38: and anti-clockwise to increase the flow.

39. 39

    Step 39: Installation is complete

40. 40

    Step 40: continue to check the plumbing connections periodically for the next few days.
