KH Director Waste Water Question

JKenny · Feb 23, 2020

Hello everyone...

I'm looking at installing the KH Director and have a question I don't see asked elsewhere. There are, effectively, 2 water outputs on the Director, 1 via the waste water pump and 1 via the "Vent Connector"/emergency drain in the rear of the unit.

I have an 1/4" silicone RO line available that runs from my DT location to the basement that can run directly into a slop sink.

Would it be possible to connect both the waste water output and the "Vent Connector" output, via a 3-way connector, to the same basement-bound RO tube? I'm concerned that the pump pressure might push water back into the Vent Connector. Maybe a one-way valve? I also don't know how much water actually comes out of the Vent Connector on a regular basis...

Not certain if this is a good idea or not, so, any thoughts or concerns would be greatly appreciated.

Thanks in advance.

Joe

I ran my waste line directly to the sink like you suggest and my vent line drains into a 1 L bottle. It doesn't accumulate much liquid but I'd be concerned about pressurizing this line.

nezw0001, thank you... I was hoping not to have another container in the sump, but, just another grain of sand I guess. You're a gentleman.

The vent line could also go back to the sump with an airgap between it and the water.

If you use the “alternative” reagent (0.1Nm HCL) you can just put both straight into your sump.. like the guys with the KHG do. Same reagent

Following. I'm interested in hearing about this.

This is what people (me included) have been using instead of the GHL reagent.. cheaper and can be dumped in sump (will be incredibly diluted by your water sample), obviously being an acid you will need to increase a tinch your ALK dosing (as when dosing vinegar i.e.)..
