shut off valve
Posted by: Fritz
Date: April 27, 2021 04:26PM


I have this kind of ball shut off, except 1/2" solder. It leaks a bit when off and a bit more at full on, but is ok at 50%.
What kind of maintenance might this require?
Tighten? Re-pack? Replace? Hurling insults?

Try tightening, but likely you’ll have to repack.

Repacking would be easiest since you wouldn’t need to remove the unit it self

when a plumber replaced the multi-turn water shut off with 1/4 turn ball valve at my old place, he did tighten the packing nut. I asked why, he said sometimes they leak.

I know you can re-pack a multi-turn valve (essentially taking the stem out and replacing the gaskets, or even replacing the entire stem with a new one. I don't think you can do that with 1/4 ball shut off valves, but previous posters said it can be done, so yeah, try that if tightening the valve does not stop the leak.

Do you have another valve to shut off water at that valve? and do you have a backup plan if things go wrong? this is why I don't like messing with plumbing. With electricity you shut off one circuit and the entire house is still functional.

Some of the newer valves have a double o-ring assembly. Older ones I
guess you have to repack, though I can't picture how that's done.
New sweat valve is $9, shark-bite $15-20.
Good luck!

My old style hose bib, round wheel on top, had been leaking for a while. I was pleasantly surprised when all I needed to do was tighten the packing nut a little. I would start with that.

I've never heard of a ball valve that used gaskets nor packing? Basically, you're doomed.

doing some further investigation, apparently the ball valve does have a packing nut under the top nut that holds the handle on.
The packing nut is perhaps 1/8" thick.
Many read as give that a tweak and it should fix the issue.
It is a Mueller B&K, a quality valve, so hopefully ....

Pretty sure the shut off in front of it is right below it in the basement with the cave crickets, spookities and 6 eyed speedersaurus.

I would not like to replace this one as it is sweated on right up against an interior wall with no space behind. Cutting it out wouldn't be fun and I'd think it be an easier replace with a shark-bite.

it starts with a regular valve but around 2' mark it changes to a ball valve... and around 8-9' mark he puts some packing rope in there.

I found a product page for a similar one. The packing is PFTE for their version. I'm a little dubious that it will be an easy job. Almost easier to replace if it weren't in that specific location.

Of the ball valves I have worked with, the stem was either sealed with o-rings or some type of packing. About a third of the valves used o-rings, don't know what the fraction is across standard valve used in residential plumbing. Depending on the design, the packing nut could be a pain to get at or require either the right type of standard tool or a special tool.

"Almost easier to replace if it weren't in that specific location."

exactly what I'd normally do. Although the valve is barely 12yo.
But I'll have to maintain in this case.

You’ll wish you replaced it when that pot metal handle breaks off and you have to leave a vise grip permanently attached.
