Drain T valve repair

[jrsavoie]

Is the drain valve repairable or rebuildable? The drain on the Tahoe was leaking until I tightened it with pliers.

I always "snug" mine down with pliers......Not to say that is correct, but better safe than sorry.

I always have also, usually with my handy dandy Leatherman Wave needlenose pliers. This valve I'm having to exert more pressure than normal and more than I used to on that vehicle.

Does tightening the packing cap help? What kind of seal is used with the valve? Does it have an O ring or is it a machined taper?

They sale that drain at a home depot or a similar store.

I always have to tighten mine down with pliers also. :agreed:

Tighten the cap should help with leaks during pressure testing. I usually use pliers on mine to get it tight.

^^ I was going to say that, ya beat me to it.

I did use a 1/4" NPT ball valve,1" brass nipple and a 90 for my Rad drain though...

F'n petcocks anyway..

I replaced mine with a similar unit and hand tighten it. Works as advertised.

I haven't had mine apart (still closing well by hand), but it does feel like a tapered seat-type seal.
