Softener and Acid Neutralizer Connections


Check out this kludge that the previous HO used to connect the backwash waste lines from the water softener and the acid neutralizer! (I swear I didn't do that!)

Well, it finally started to leak. My questions:

1. I did a short term fix by reconnecting only the softener line with a 1/2 inch male-male nipple to connect just the tubing that comes up from the bottom and out the top. Any thoughts on the right way to connect that gray hose? It looks like it clamps over a 3/4 inch pipe in that kludge.

2. Should there be backflow preventers? I mean when one of them backwashes is the back pressure harmful to the other?

Thanks!

If it is possible run two lines , one for each to the drain, if not possible then a check valve in each of the lines will work.

Softener and Acid Neutralizer Connections


With a properly operating valve on the softener and Acid Neutralizer a separate backflow preventer is not necessary. The valve on softener and the neutralizer prevents backflow into the respective unit. If the valve on either fails the results are typically not serious so the benefits of a separate backflow preventer are minimal.

A downside of backflow preventers is that they introduce some backpressure into the drain system--typically not a problem but not desirable either.
