What is this?

Looks to me like a quick connect for an air line with a pressure regulator.

X2. And probably added by a previous owner, not WRV.

The red pex line is the bleed drain from the RO membrane.

That was leaking like crazy. 49 gallons of fresh water lost. Why would that happen? I did have the RO switched on with no water coming from the city.

The leak looks like it coming from the black ABS line. Is that correct?

No, it was coming from the red plex line that filled the waste tank all the way to the hose then into the grey waste line up to the waste gate, then up the 1/2” vent hose that is connected to the abs plastic vent tube.

I was told in an earlier post that was the RO bladder line. But if so, the. Would it be leaking?

I have a short video showing the leak. But don’t know how to post it.

If the pex line is split, splice in a coupler to seal it up.

No split just water draining from the pex line into the waste lines.

Deploy your sewer hose and open the hand valve at the outlet. Keep your blade valves closed.

The question is why did it leak all the water in the first place? If I open the waste valve will that stop it from dumping all the water in the RO tank?
