Reduce regeneration water flow...

[BrownTiger]

Need some ideas how to address this issue with water back spillage [~1/4 measuring cup].

Have GE 44k[Not ideal, but it works..] water-softener on city water - plumbed with 1" copper lines. Drain outlet is 3/4" garden house -7' long to 1.5" air drain gap adapter above the softener.

This drain gap adapter connected to 10" vertical elbow to 1.5" ptrap to 2" - 3/16 pitched "horizontal" drain pipe. [Shared with laundry washer, washer works without any issues].

During some either Backwash or Fast rinse phase (not sure) it overflows the 1.5" pipe and spills water outside about 1/4 cup of water (may be less) but each time. Need to reduce the flow somehow... I verified ptrap no issues there. My though is that 1" inlet at 60+ psi is too much for 1.5" ptrap to handle.

1. How can I reduce the flow?
2. Is there a way to advance GE softeners phases so I do not have to wait 3 hours to test.

Thank you very much.

Is this something new? Can you provide a picture of the drain and trap area?

Can you measure the flow the standpipe is dealing with? I would guess that should be about 2 to 2.4 gpm.

If you can play that drain line into a 5-gallon bucket, and if S is the number of seconds to fill the bucket, the gpm=(300/S)

The purpose is to see if the softener is sending too much water, or if the standpipe is not accepting a proper amount of water.

Do you have a media tank and a separate brine tank along side, or is this an all-in-one cabinet unit?

What type of elbow? If it is PVC you want the long sweep as shown on the right picture. Is it PVC or Iron?

Sorry I did not say it right.
Vertical 10" pipe connected to 1.5" ptrap. At the top of 10" air gap adapter.
I used CHARLOTTE PIPE 1 1/2 DWV P-Trap with Solvent Weld Joint DWV connection. It has single nut on water slip joint.

Thinking of redo 3/4" hose.. Get 5/8" adapter to may barbed 1/2" and run 1/2" clear hose to air gap adapter.
This is a big unit and my supplies are huge 1". Somehow 10" pipe + ptrap to 2" waste get overrun a little.

Dropping the hose ID to 1/2 inch should not matter. I would be inclined to increase the standpipe height to maybe 30 inches.

Any response to #3?

Agree, extending the standpipe to 30" will allow additional reserve capacity before the P-trap. A 10" vertical standpipe is too short.

A 2" laundry standpipe and 'P' trap is now commonly utilized. Since the horizontal run past the 1.5" P-trap is 2", perhaps replacing the 1.5" standpipe and P-trap with 2" versions would be a relatively simple retrofit to increase the laundry drain's flow rate.
