Anyone know what this valve is?

Hi Folks

Any one know what this valve is. It for the fresh water supply and It ls located after the output of the water pump. I just noticed this valve is leaking very slowly (a drip every few minutes) from the control knob I turned the control knob many turns in each direction but do not notice any difference in the water output. :confused:

Looks like it might be tho an ice maker. Appears to be in shut off position.

X2 - that's a water shut-off valve alright. If it's developed a drip it probably needs to be replaced. Something you can pick-up at Home Depot or Lowes.

Definitely not shutting off. To do so the handle would be at 90 degrees to the hose line.

From the photo, it looks like it is a rebuildable valve. If you shut off the water and drain the system you should be able to turn the top of the valve out of the body with the nut under the handle, clean it, replace o rings, and reseat it. Problem is the flex tubing may crack, valve may break, and repacking the valve may not be possible. If you choose to try to rebuild it, have a new sharkbite valve on hand just in case.

Agree it appears to be a shut off valve that needs to be 90* to the line to cut water flow. The problem I see is the bracket that is holding the line to the wall. It doesn’t look to be affixed with screws or other removable hardware and you’ll need to remove that bracket to work on the valve.

The water tubing , being grey , and not clear , could be ; poly B ; and not pex .
There is writing on the tube to the left of the valve .

Knowing exactly what you're dealing with is important if replacing the valve is required , poly B , could require a different valve and clamps.

The valve is a cheap one that turns several times to open and close

The packing often leaks

Tighten it lightly

Ours, at least, is not a ball valve, so you cannot tell the difference between open and closed by the position of the handle. I do agree that it looks like an ice maker valve, though.

To the OP, if it's leaking from the packing (that is, around the valve stem or from the threaded part of the center), try to tighten it a bit. Don't overdo it. You're aiming for snug, not tight.

The good news is a replacement valve is probably less than $10, perhaps even less than $5.

[Edit: I see Milford 47 gave the same advice about trying to tighten it. I am guilty of not reading all the posts before posting. Sorry 'bout that. But it's still an inexpensive valve to replace if that doesn't work. Take it out and bring it to a good hardware store.]

Hi Folks
Thanks for the replies. A couple notes on the comments..
1) The valve is not for the ice maker...It is in the Main Water Line. It is right on the Output of the Water Pump.
2) The valve is not mounted on the wall. It is mounted on the floor. I have a couch along the window. Under the couch cushion is the Fresh Water tank, The Water Pump and this valve.
3) The valve does not have a adjuster nut to tighten the knob. So I dont see how to tighten.

Attached is a closer view. You can see where the water is seeping. Also note.. The valve appears to have an output that runs down and outside of the coach. ( circled this in red) I suspect this may be a valve to allow one to completely drain the water system. But I can not see underneath because the outside storage bay blocks the view.

My thought is to remove this point of failure and replace it with a straight line. I am boondocking currently and will have to cut my trip short bc it is starting to soak the carpeting.

That makes it seem that it's a low point drain valve. If it is then if you put in a straight piece and eliminate the valve you might have water constantly running out of wherever the other end of the line is. Just a thought.

Put a drip pan under it and turn off your water pump until needed. Of course that won't work is it is spurting. Might be able to wrap in tape with pressure off for a temporary fix.

Hi Folks
Just wanted to provide an update. The valve was a low point drain valve that allows one to drain the fresh H2O system out the bottom of the coach. Also note the valve does NOT open an close by turning the petcock as one would expect. The valve is open by physically grabbing the petcock and pulling it upwards, and the valve is closed by physically pushing the petcock down. THat is why when I rotated the petcock it didnt make any difference. Anyway that thing is gone, replaced with a straight pipe.
BTW I did find two other low point valves under the kitchen sink so I can use thoes if needed.
