Discovery: Drain valve handle

[ccsmith51]

I have a 2007 Discovery 39V. The three handles for the Fill / Bypass, Hot, and Cold drains have broken.


They were metal and I would like to replace them with metal. I bought some of the plastic ones but they did not last long.


Does anyone know where I can buy metal ones?

If the valves are in PEX plastic pipe , any plumbing supply should have what you're after . Take in an old valve for sizing .

Skip,


Thanks, but replacing the valves themselves is much more involved than I want to get into.


I'm just looking for the valve handles. If I can't find them I'll just continue to use pliers.

Square or splined valve shaft ?

Can you find metal valves and just use the handles?

It might be useful if you send photos.
Using pliers will eventually damage the part even more, and most likely at the worst time.

Here's a photo of the By-Pass valve, the others are the same.

Measure the square ; if it's 1/4" then Google ; 1/4" square water valve handles .

They are out there .

The original handles had a recess that the valve stem fit into, and prevented the handle from contacting the panel around the valve stem. The attaching screw secured the handle to the end of the stem, and the recess held the stem for rotation.



All the ones I have seen so far are just like in the photo above with multiple examples. They just slide over the valve stem, with nothing stopping them from moving down and contacting the panel.


Even if I put small washers around the stem to keep the handle from contacting the panel, there is no way to tighten the handle to the stem.


I was hoping that someone here had the same type of handle and could point me to where I could find some. Or, show how they installed a replacement handle.


Thanks,

Playing around on the interwebs, I found this:

Thank You F4Gary,


I actually purchased those awhile ago. They are 3D printed and not very sturdy. Over time they both weakened and cracked where they capture the valve stem. So now the handle rotates on the stem, but the stem does not turn.

Sounds like you need to do something about the valves themselves. They're evidently harder to turn than they should be so you need to either replace or maybe try taking them apart and cleaning/lubricating with plumber's grease.
