DOS for AWC Plumbing Question

[bpro32]

For those of you using a Neptune DOS for AWC, how do you plumb the NSW container and how do you keep the tube at the bottom? I was thinking of using a push connect bulkhead at the top then just having a bunch of extra tubing that would coil up at the bottom but I'm sure there is a better way.

Heat the RO tubing, Once the tubing is hot lay it straight. Let it cool and it will be straight from then on.
I have my tube as you said above one end in a bulkhead then the straight part in the tank 1/2” off the bottom.
Despite my running a pump in my tank every few hours the tubing keeps it’s memory and stays straight down.

Oh and I don’t use a Neptune DOS. I use a GHL Maxi.. same basic pump.

Look at this post to see what I did.

Very nice, loving the cabinet look. And it does indeed go with the house. Thanks, the pictures don't do the area justice.... Darn blue tinted lights LOL

I’ve got a media bag around the bottom of the DOS tube (to prevent anything getting in and blocking it) but when the DOS tube is primed and has water in, it stays around the bottom anyway

I zip tied a piece of PVC at the bottom of the tubing. It worked well to keep it at the bottom.

Any of those approaches will work. I just thread the RO tubing down a piece of 1/2” PVC. Just keep the end a bit off the bottom. Mixing up most salt mixes results in some dust/precipitate that will jam up the DoS.
