leaving the old valve = job security.

yup, wrong thread, unless the tree root crept all the way up the line and wrapped around the valve
Wonder where the original thread regarding the root problem was ?
Just found it, garden sprite responded to this question on jan.13 @ 5:41 pm, and made mention of clogged sewer lines

Joe, given the weather in the SE, it might be warmer and less snowy ABOVE the Mason-Dixon line in the winter! If I came to Virginia to do your summer projects, could I expect plenty of time to go to the ocean?

Nona, actually your post was on target, since I mentioned the tree root problem I've had. I did check out the link you posted and will investigate it further.

I know that copper sulphate has been used to kill tree roots, so that's a good suggestion.

The tree closest to my yard has grown fat and aggressive since the house was abandoned almost 2 years ago. I suspect it's feeding off two sewer lines.

I've been thinking about pouring copper sulphate directly at the base of the tree and/or onto some feeder roots but this isn't my preferred option.

Anyway, thanks for the suggestion as it was truly helpful.

Swschrad, now I know the truth behind what the plumbers do and don't do! Could it be that they're also feeding the tree roots when they snake them out?
