Drain line question

[picktoo]

Can a 1/2 inch braided stainless faucet supply hose be used as the primary drain line for a water softener? The one I'm considering is rated at 125 PSI.

I'm finalizing the re-install of my softener. I turned it 90 degrees to better fit the space it occupied, but that made the plumbing connections a bit more complicated. I used braided stainless water heater hoses between the supply/delivery connections and my PVC pipes, and they're great. Connecting the drain line with rigid PVC (as it was originally) would require a lot of joints, so I tried using semi-flexible vinyl (?) tubing and barbed irrigation connectors clamped into each end. Those connectors supposedly had IP threads, but they leak pretty badly during backwash. And, yes, I used teflon tape on them.

How long is the drain run?

That line does not see much pressure, because one end is open. Are you saying that the barbed connector you screwed to the softener leaks at the threaded part? Sounds cross-threaded.

Yes. at the softener end, and the drain line end. They threaded on with no resistance, and they look perfectly straight.

A braided faucet supply line is a pretty small interior line.

Yes, and that is my concern.

1. How Long is ....

And I am not asking about an old Oakland Raider or the other guy. If your run is over 20 ft, you should probably increase to 3/4.

2. What softener controller is this?

Usually people use tubing with barbed threads and worm-gear clamps.

If you really want nice full-flow flex, consider a Falcon Stainless connector. You could use a 3/4 connector intended for water heaters. Some are rather stiff, but give some flex, are readily available, and cheap. The falcon is more flexible. So use a plastic or brass adapter as needed.

If you ran 3/4 CPVC instead of PVC, you could ease your connection from flex to pipe using SharkBite or similar push-on.

Thanks, guys, but I finally fixed the leaks. I re-taped the threads and reeeally tightened down the connections. No more leaks . . . at least at those points. But, check here for a new issue https://terrylove.com/forums/index.php?threads/drain-line-into-waste-vent.76256/
