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.

Is the pipe wall thick enough for taping? I have the taping tool i can loan u when we meet next week to buy your trigger system ato container.

 

[Flagg37]

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.

 

[Gablami]

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.

Just remind me before we meet for the ato container.

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:

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?

 

[Julius Chen]

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.
