1/2" ID x 1/2" OD quarter turn valve


Does such a thing exist? I searched the forums but I was unable to find an answer.

My plumber put in a new shower and plumbed a second shower head, from a T, after the on/off valve. He installed a shutoff valve in the line but it doesn't shut off 100% so it drips cold water whenever the shower is on but it's not in use. You can improve this by running the water from that head, until it heats up and drips hot water while you shower.

I've found another valve that bills itself as 100% shut off but it comes with a price tag of $40.

I was thinking that if I could find a 1/4 turn valve, it might make a cheaper alternative. In lieu of that, are there any better options for me?

I am aware that this is unorthodox and against code in some areas. However, the cost of retrofitting a second flow control would be cost prohibitive.

Is this valve at the 2nd shower head? I'm not really following what the plumber did. And why those pipe sizes? What kind of pipe are you working with?

Yes. The shut off is at the other shower head.

And maybe I'm wrong about the sizes. Isn't the pipe connected to the shower head 1/2" ?

Yes, it is 1/2" iron pipe size, but the O.D. is actually larger.
I haven't had good luck with the type of valve your looking for- similar to your experience. They are expensive though. Try a local plumbing supply house. Their products are usually a notch above the box stores

Is there any other type of valve I could substitute? A stainless steel ball valve or something else?

Any 1/2" I.P. ball valve will work as long as it is for potable water.

I'm not too familiar with the fittings so I'm not sure the search terms to use.

I'm looking for something that would be male at one end and female at the other. I assume stainless or chromed brass would be what I need. Or will I need a nipple to go along with the ball valve?

Can you point me in the right direction?
