We are removing a sink from a wet bar that used to be in what is now our family room. We have to use compression fittings because our shut off valves are old and don't shut the water off completely, there's still quite a bit of leakage which makes soldering impossible.
We have installed compression fittings with caps to condemn both hot and cold lines. We put teflon tape around the threads as recommended by hardware store employee.
We have two questions:
1- Is it normal for them to be so darn hard to tighten? We're still getting about a drop every hour after we've tighten the heck out of it.
2- Are compression fittings as trusworthy as a soldered connection? Will it last as long?
