Couldn't stop trickle of water during repair

This is related to another discussion that finished. In the photo of the main shut-off valve that I recently rebuilt,
you can see where I capped off that lower horizontal pipe. That was for an inoperative irrigation system which I will never use again, I could not stop the small trickle of water coming out of that horizontal pipe. I shut off the municipal water valve of course.

I tried to solder a cap on. But water dripped right through the solder. I tried the white bread trick. But it didn't work. I probably didn't use enough bread. I was running out of time. So I found this fitting with 7/8 inch compression on one end and 3/4 inch threaded cap on the other. It worked. No leaks. I know you might be wondering where did 7/8 inch OD copper pipe come from. That pipe was from 1996. So mayve that is what they used back then.

Anyway, How would you have stopped the trickle of water? People always say use a shop vac. But will it still pull out the water with the vacuum hose being too wide for the pipe opening? Would you create a vacuum at a faucet insider the house, or that outside copper pipe opening? Or would you have used a different method altogether?

I just want to be prepared if this happens again. I'm not sure sure if I can justify the cost of buying a shop vac.

Not sure if it would work in your situation as I can't see the picture, but you can always crush the pipe flat, bend it back on itself (upright) and solder it closed.

On PVC I've take a piece of bread and wad it up to stop the water trickle. The bread will dissolve sometime after you are done.

Nothing wrong with using a compression fitting.

It's usually best to turn on any/all faucets in the house to let the pipes actually drain out. Sometimes, the continual dripping is actually coming from a higher faucet/pipes just slowly draining down. Also, by draining the pipes and leaving the faucets open, it gives the water somewhere else to go. Depending on the height of where you're repairing, it can help keep water away.

Ok. Try this link. There must be a problem with this website. I was getting a 503 error which is server related.
Yes, I opened faucets in the house. Would the wet/dry vac have taken care of that dripping? I also wonder if my air compressor would have pushed the water back down into the system?

Yes. I see the photo now. I should cover that copper hardware with something to prevent copper theft.
I don't want to paint over it. Maybe plant a shrub in front of it or something.

I inadvertently posted 3 photos because I thought there was a technical problem. The moderator might want to delete the extra photos on this posting to open space for other members who need to post their photos on other topics.

A Shark Bite cap would have solved the problem in no time. I always carry a couple in my plumbing box.

Put it on correctly and it will probably outlast you. There was a lot of bad press when they first came out as many plumbers felt threatened because the Shark Bite fittings were so DIY friendly. I have yet to hear of one that failed when properly installed.
