• The proper way to install supply lines is with the brass nipple as shown above. The tube can also be inserted into a brass solder style male adapter. The supply line will slide into either fitting. Both should be stubbed out of the floor between 3/4" and 1".  The brass nipple is best because the installer can easily slide the supply tube up and down when connecting to the faucet. If you go into an old house, look at the nipple coming out of the wall beneath the toilet. You will see a brass nipple attached to a valve or "stop". This is the best way.
• When using "solder" or "sweat" male adapters, the supply bottoms out in the fitting but still has ample room to make a proper seal. To fit the many old style faucets our double offset supply is 9/16 outside diameter which will fit the above fittings. Our single offset and straight supply tubes are 1/2" O.D..

• Installation with  "solder" or "sweat" male adapter. Sometimes the fit may be a little tight, but will go in with a little twist.
