    Leak at supply line and valve under the sink
    I went to replace a faucet in the restroom sink. The existing lines where too short for the new faucet. I bought two new 1/2 in lines. Came home connected to faucet, then it didn't connect to valve. Went back to the hardware store and they told me the valves I have at home are 40 years old. I bought 2 new valves. I installed both exactly the same. The valve connected to the cold water is leaking at the connection from the pipe to the valve. I tried adding more teflon tape and same. I switched the two valves and the cold water pipe still leaks. Please tell me its an easy fix and that I don't have to change pipes behind the wall

    Shouldn't be using Teflon tape if you are installing compression fittings... may be that is the issue... ;)
