Hi I need to get remove a sink and am not to sure on how to cap the
pipes off. The supply lines are copper pipes. I know there are caps for
them but if i put the cap on and solder it will it be stong enough to
not blow off from the pressure of the water? As to the drain is there a
cap that I can use that will keep sewer gas from getting in to the room?

Instead of capping the copper, install shutoff valves (stops)
which use compression fittings. No soldering, plus you have
shutoffs for next time.

A wet rag stuffed in the drain is sufficient.
For a more permanent solution, get a Fernco Quick Cap:

Super,

Yes the copper caps will withstand the pressure if you are a competent
solderer. I've never capped off a drain pipe but it's not hard to get a gas
tight seal. I think they use rubber caps attached with hose clamps.

Yes to both. How to do it and what to use depends on the particular
situation. I suggest that if you are questioning this, that you should not
be doing your own soldering.

IMHO,

For the cut water lines, I think you're missing an opportunity to put
in some valves. As for the caps, I have capped water lines and
they've lasted 13+ years.

Now for your sewer line, they sell inside expanding plugs at your big
box stores. Just ask the person in the plumbing section for help.

Good luck,

Not a problem.

Test plug -- looks like a big rubber cork with a wing nut sticking off
one end. $3.00. For a sink drain, you probably want a 1-1/4" plug.

It appears to me the sink is being totally removed so there would be no
future need for water there. Of course it is not 100% clear that is what
the OP intends so your suggestion certainly would be mine if there was any
likelihood of putting a sink or other water user there.
