Plastic ball valve leaking

[sinister99]

A plumber installed this valve a few years ago as an isolation valve for my water service. I've cycled it a number of times recently, and it has developed a slow drip from a weep hole on the valve body. I'm guessing this means water is leaking around the ball. I've cycled the valve a few more times and tried it in throttled positions to try to flush the seat, but there was no change.

Is there any fix for this slow leak? If not, what type of valve is this so I can replace it?

Also, shouldn't there be a grounding jumper around the plastic valve since the rest of my system is copper?

Any thoughts? It is still leaking very slowly a month later.

I’m not a big fan of all-plastic valves in critical locations. Personally, I’d tear it out and replaces with a brass ball valve.

It looks like it is connected with either compression or threads, can’t tell for sure, but you’d need to know which before trying to replace it. I don’t think that there’s much you can fix in the thing unless it’s a threaded connection that needs to be tightened.

Yeah, this was years ago before I knew anything about plumbing. The plumber also installed sharkbite fittings inside a wall in another location instead of sweating copper (even these leaked and I had to call him back). Now I would have called him out, but I didn't know better then.

It is definitely not leaking from the threaded connections. It is leaking past the ball through a telltale weep hole, so I think the valve needs to be replaced. There was no spring in the 3/4" copper pipe when he put it in.

I ditto what he said...
Replace it.
