    Cool. I used the first one (nail) and it was loose.

    The screw type should work if I add plastic expander.

    Have u used the screw type and is its opening right for 1/4" OD tubing?

    I've only used the nail ones but you're right, they pop out easily. Any where I can I nail it into wood. Door casing, shelving; stuff like that.

    You can also drill a hole in the ceiling and run it above the ceiling.

    I haven't used it before but I bet it would work.

    Well, after all that discussion, I ended up drilling a 0.25 in hole and squeezed the ro tubing into it.

    It should be thick enough. I regularly tap .065" material but that is stainless steel not ABS. If you can tap it, that would be much better than simply inserting it into the pipe.

    Yes I think it is thick enough. Home Depot didn't have the tap. Thank you for offering to let me borrow. Might take you up on that.

    So I drilled and tapped with NPT thread this morning thanks to a tap kit loaned to me from @Julius Chen. Very doable.

    Testing it out:

    In the crawl space:

    Cool. I'd run the rodi tubing inside 1/2" pvc pipe in the crawl space, so rodents wont chew on it.

    What size tap did you use? That’s the 1/4” fitting, correct?

    Look for a 1/4 - 18NPT tap. It uses a 7/16” drill bit.

    Thanks!
    I do have a tap that worked for one but I feel the fitting is a bit loose and only a few wraps in teflon tape makes it feel snug. I will get a set that size.

    I have found yelliw sediment inside 1/4” tubing in both nsw and drain lines. Overtime they got blocked real bad.

    I thus use 3/4” pvc pipe for the section inside wall and in crawl space. 1/4” tubing only at tank and garage where i can easily check and replace.

    You got build up from the RO drain line or a drain line from your tank?

    Two lines: drain line from tank (not surpring), and new salt water line from brute can to tank (surprising).

    The build up is most obvious where there is a u shape (where sediment can collect).

    I’d say I need to change the lines every 4 months (running at 3-5 gallon/day).

    So I built this fitting to connect between the 3/4" pipe and 1/4" the peristaltic pump. The slip between clear tubing and the white fittings will not be glued, so I can slide the fitting out to replace the 1/4" tubing when needed.
